MM74HC423A Dual Retriggerable Monostable Multivibrator September 1983 Revised January 2004 MM74HC423A Dual Retriggerable Monostable Multivibrator General Description Features The 74HC423A high speed monostable multivibrators (oneTypical propagation delay: 40 ns shots) utilize advanced silicon-gate CMOS technology.Wide power supply range: 2V–6V They feature speeds comparable to low power Schottky Low quiescent current: 80 μA maximum (74HC Series) TTL circuitry while retaining the low power and high noise Low input current: 1 μA maximum immunity characteristic of CMOS circuits. Fanout of 10 LS-TTL loads Each multivibrator features both a negative, A, and a posi- Simple pulse width formula T = RC tive, B, transition triggered input, either of which can be used as an inhibit input. Also included is a clear input thatWide pulse range: 400 ns to ∞ (typ) when taken LOW resets the one shot. The MM74HC423A Part to part variation: ±5% (typ) cannot be triggered from clear. Schmitt Trigger A & B inputs allow rise and fall times to The MM74HC423A is retriggerable. That is, it may be trig- be as slow as one second gered repeatedly while its outputs are generating a pulse and the pulse will be extended. Pulse width stability over a wide range of temperature and supply is achieved using linear CMOS techniques. The out- put pulse equation is simply: PW = (R ) (C ); where EXT EXT PW is in seconds, R is in ohms, and C is in farads. All inputs are protected from damage due to static discharge by diodes to V and ground.
