HD74HC123A Dual Retriggerable Monostable Multivibrators (with Clear) REJ03D0564-0200 (Previous ADE-205-438) Rev.2.00 Oct 11, 2005 Description This 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 HD74HC123A can be triggered on the positive transition of the clear while A is held low and B is held high. The HD74HC123A is retriggerable. That is it may be triggered repeatedly while their outputs are generating a pulse and the pulse will be extended. Pulse width stability over a wide range of temperature. The output pulse equation is simply: tw = (Rext) (Cext). Features High Speed Operation High Output Current: Fanout of 10 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current Ordering Information Part Name Package Type Package Code (Previous ...
