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.
