_*ECS-3953M is also compatible with a supply voltage of +3.0V DC ±0.3V_ 

_**Inclusive of 25°C tolerance, operating temperature range, input voltage change, load change, aging shock and vibration._ 

_***An internal pullup resistor from pin 1 to 4 allows active output if pin 1 is left open._ 

_Note: A 0.01 μF bypass capacitor should be placed between VCC (Pin 4) and GND (Pin2) to minimize power line noise._
