Timing is initialized by turning on power, whereupon the power-on reset is enabled and initializes the counter, within the specified VDD range. With the power already on, an external reset pulse can be applied. Upon release of the initial reset command, the oscillator will oscillate with a frequency determined by the external RC network. The 16-stage counter divides the oscillator frequency (fosc) with the n[th] stage frequency being fosc/2[n] . ## **Features** - Available Outputs 2[8] , 2[10] , 2[13] or 2[16] - Increments on Positive Edge Clock Transitions - Built-in Low Power RC Oscillator (±2% accuracy over temperature range and ±20% supply and ±3% over processing at < 10 kHz) - Oscillator May Be Bypassed if External Clock Is Available (Apply external clock to Pin 3) - External Master Reset Totally Independent of Automatic Reset Operation - Operates as 2[n] Frequency Divider or Single Transition Timer - Q/Q Select Provides Output Logic Level Flexibility - Reset (auto or master) Disables Oscillator During Resetting to Provide No Active Power Dissipation - Clock Conditioning Circuit Permits Operation with Very Slow Clock Rise and Fall Times - Automatic Reset Initializes All Counters On Power Up - Supply Voltage Range = 3.0 Vdc to 18 Vdc with Auto Reset Supply Voltage Range = Disabled (Pin 5 = VDD) Supply Voltage Range = 8.5 Vdc to 18 Vdc with Auto Reset Supply Voltage Range = Enabled (Pin 5 = VSS) - NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC-Q100 Qualified and PPAP Capable - These Devices are Pb-Free and are RoHS Compliant **SOIC-14 SOEIAJ-14 TSSOP-14 D SUFFIX F SUFFIX DT SUFFIX CASE 751A CASE 965 CASE 948G** ## **PIN ASSIGNMENT** **==> picture [114 x 111] intentionally omitted <==** **----- Start of picture text -----**

**Figure 5. RC Oscillator Frequency as a Function of Rtc and Ctc** ## **OPERATING CHARACTERISTICS** With Auto Reset pin set to a “0” the counter circuit is initialized by turning on power. Or with power already on, the counter circuit is reset when the Master Reset pin is set to a “1”. Both types of reset will result in synchronously resetting all counter stages independent of counter state. Auto Reset pin when set to a “1” provides a low power operation. The RC oscillator as shown in Figure 3 will oscillate with a frequency determined by the external RC network i.e., **==> picture [195 x 37] intentionally omitted <==** The time select inputs (A and B) provide a two-bit address to output any one of four counter stages (2[8] , 2[10] , 2[13] and 2[16] ). The 2[n] counts as shown in the Frequency Selection Table represents the Q output of the N[th] stage of the counter. When A is “1”, 2[16] is selected for both states of B. However, when B is “0”, normal counting is interrupted and the 9th counter stage receives its clock directly from the oscillator (i.e., effectively outputting 2[8] ). The Q/Q select output control pin provides for a choice of output level. When the counter is in a reset condition and Q/Q select pin is set to a “0” the Q output is a “0”, correspondingly when Q/Q select pin is set to a “1” the Q output is a “1”. When the mode control pin is set to a “1”, the selected count is continually transmitted to the output. But, with mode pin “0” and after a reset condition the RS flip-flop (see Expanded Block Diagram) resets, counting commences, and after 2[n−1] counts the RS flip-flop sets which causes the output to change state. Hence, after another 2[n−1] counts the output will not change. Thus, a Master Reset pulse must be applied or a change in the mode pin level is required to reset the single cycle operation. ## **DIGITAL TIMER APPLICATION** **==> picture [235 x 151] intentionally omitted <==** **----- Start of picture text -----**

When Master Reset (MR) receives a positive pulse, the internal counters and latch are reset. The Q output goes high and remains high until the selected (via A and B) number of clock pulses are counted, the Q output then goes low and remains low until another input pulse is received. This “one shot” is fully retriggerable and as accurate as the input frequency. An external clock can be used (pin 3 is the clock input, pins 1 and 2 are outputs) if additional accuracy is needed. Notice that a setup time equal to the desired pulse width output is required immediately following initial power up, during which time Q output will be high. **www.onsemi.com** **6** **MC14541B** ## **REVISION HISTORY** |**Revision**|**Description of Changes**|**Date**| |---|---|---| |16|Rebranded the Data Sheet to**onsemi**format.
