74HC221 Dual Monostable Multivibrator with Reset IC (74221 IC) DIP-16 Package
74HC221 is a 16 Pin Hex D-type Flip-Flop with Reset IC having 2V to 6V Operating Voltage range with 5.2mA output current and 1uA low input current. It utilize advanced silicon-gate CMOS technology. They feature speeds comparable to low power Schottky TTL circuitry while retaining the low power and high noise immunity characteristic of CMOS circuits. Each multivibrator features both a negative, A, and a positive, B, transition triggered input, either of which can be used as an inhibit input. Also included is a clear input that when taken low resets the one shot. The 74HC221 can be triggered on the positive transition of the clear while A is held LOW and B is held HIGH.
