The IN74HC221 will function at 2.0 V but for optimum pulse width stability, VCC should be above

3.0 V.

This device contains protection circuitry to guard against damage due to high static

voltages or electric fields. However, precautions must be taken to avoid applications of any voltage

higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and

VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or

VCC). Unused outputs must be left open.
