HD74HC221

Dual Monostable Multivibrators (with Schmitt Trigger Input); ? High Speed Operation\n? High Output Current: Fanout of 10 LSTTL Loads\n? Wide Operating Voltage: VCC = 2 to 6 V\n? Low Input Current: 1 μA max\n? Low Quiescent Supply Current;

Description\nEach multivibrator features both a negative, A, and a positive, B, transition triggered input, either of which can be used as an inhibit. Also included is a clear input that when taken low resets the one shot. The HD74HC221 can be triggered on the positive transition of the clear while A is held low and B is held high. This device is a non-retriggerable, and therefore cannot be retriggered until the output pulse times out. The output pulse equation is simply: tW = 0.7·(Rext)·(Cext)
