**TS556** Low-power dual CMOS timer **==> picture [61 x 39] intentionally omitted <==** ## **Features** - Very low power consumption: 220 µA typ at VCC = 5 V 180 µA typ at VCC = 3 V - High maximum astable frequency 2.7 MHz - Pin-to-pin and functionally compatible with bipolar NE556 - Wide voltage range: 2 V to 16 V - Supply current spikes reduced during output transitions - High input impedance: 10[12] Ω - Output compatible with TTL, CMOS and logic MOS **==> picture [46 x 39] intentionally omitted <==** **==> picture [102 x 137] intentionally omitted <==** **----- Start of picture text -----**<br> N<br>DIP14<br>(Plastic package)<br>D<br>SO14<br>(Plastic micropackage)<br>**----- End of picture text -----**<br> ## **Description** The TS556 is a dual CMOS timer which offers a very low consumption: (Icc(TYP) TS556 = 220 µA at VCC = +5 V versus Icc(TYP) NE556 = 6 mA), and high frequency: (f(max.) TS556 = 2.7 MHz versus f(max.) NE556 = 0.1 MHz). In both monostable and astable modes, timing remains very accurate. The TS556 provides reduced supply current spikes during output transitions, which enable the use of lower decoupling capacitors compared to those required by bipolar NE556. **Pin connections** (top view) **==> picture [151 x 112] intentionally omitted <==** **----- Start of picture text -----**<br> Discharge 1 14 +VS<br>Threshold 2 13 Discharge<br>Control 3 12 Threshold<br>Voltage<br>Control<br>Reset 4 11 Voltage<br>Output 5 10 Reset<br>Trigger 6 9 Output<br>GND 7 8 Trigger<br>**----- End of picture text -----**<br> Due to the high input impedance (10[12] Ω), timing capacitors can also be minimized.

Referring to figure 2, the external capacitor is initially held discharged by a transistor inside the timer, as shown in _Figure 4_ . ## **Figure 4. Application schematic** **==> picture [154 x 117] intentionally omitted <==** **----- Start of picture text -----**<br> VCC<br>Reset<br>R<br>Trigger<br>1/2<br>C<br>TS556<br>Out<br>Control Voltage<br>0.01 Fμ<br>**----- End of picture text -----**<br> The circuit triggers on a negative-going input signal when the level reaches 1/3 VCC. Once triggered, the circuit remains in this state until the set time has elapsed, even if it is triggered again during this interval. The duration of the output HIGH state is given by t = 1.1 R x C. It can be noticed that since the charge rate and the threshold level of the comparator are both directly proportional to the supply voltage, the timing interval is independent of the supply. Applying a negative pulse simultaneously to the Reset terminal (pin 4) and the Trigger terminal (pin 2) during the timing cycle discharges the external capacitor and causes the cycle to start over. The timing cycle now starts on the positive edge of the reset pulse. While the reset pulse is applied, the output is driven to the LOW state. When a negative trigger pulse is applied to pin 2, the flip-flop is set, releasing the short circuit across the external capacitor and driving the output HIGH. The voltage across the capacitor increases exponentially with the time constant τ = R x C. When the voltage across the capacitor equals 2/3 VCC, the comparator resets the flip-flop which then discharges the capacitor rapidly and drives the output to its LOW state. _Figure 5_ shows the actual waveforms generated in this mode of operation. When Reset is not used, it should be tied high to avoid any possible or false triggering. ## **Figure 5.

The external capacitor charges through RA and RB and discharges through RB only. Thus the duty cycle may be precisely set by the ratio of these two resistors. In the astable mode of operation, C charges and discharges between 1/3 VCC and 2/3 VCC. As in the triggered mode, the charge and discharge times and therefore frequency, are independent of the supply voltage. ## **Figure 6.

The charge time (output HIGH) is given by: t1 = 0.693 (RA + RB) C and the discharge time (output LOW) by: t2 = 0.693 x RB x C Thus the total period T is given by: T = t1 + t2 = 0.693 (RA + 2RB) C The frequency of oscillation is then: **==> picture [79 x 18] intentionally omitted <==** The duty cycle is given by: **==> picture [54 x 17] intentionally omitted <==** ## **Figure 7.

STMicroelectronics is a global leader in the semiconductor industry, recognized for developing highly integrated, energy-efficient solutions that power modern electronics. With a strong focus on innovation, ST provides a comprehensive portfolio of microelectronics that address the demanding requirements of industrial, automotive, communications, and consumer applications. Our extensive selection of STMicroelectronics components is built around a robust lineup of discrete semiconductors and circuit protection devices. We offer a wide variety of single MOSFETs, Schottky diodes, and fast and ultrafast recovery rectifier diodes, designed to deliver exceptional efficiency and thermal performance in power management and conversion systems. For robust circuit protection, our inventory features hundreds of transient voltage suppressors and TVS diodes that safeguard sensitive electronic components against destructive voltage spikes. In addition to core power discretes like TRIACs, SCRs, bipolar transistors, and single IGBTs, our STMicroelectronics range includes specialized integrated passive filters and MEMS sensors. Furthermore, ST offers advanced integrated passive devices, such as baluns and RF filters, which utilize high-quality monolithic RF IPD processes on glass or high-resistance silicon substrates. These components provide competitive cost structures, reduced power losses, and simplified RFIC-to-antenna matching, ensuring optimal system performance and delivering the reliability required for next-generation wireless and power designs.
About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
