| MM74HC123A Dual Retriggerable Monostable Multivibrator MM74HC123A Dual Retriggerable Monostable Multivibrator The MM74HC123A high speed monostable multivibrators one shots 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 MM74HC123A can be triggered on the positive transition of the clear while A is held LOW and B is held HIGH. The MM74HC123A 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 and supply is achieved using linear CMOS techniques. The output pulse equation is simply PW = REXT CEXT where 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 VCC and ground. s Typical propagation delay 25 ns s Wide power supply range s Low quiescent current 80 µA maximum 74HC Series s Low input current 1 µA maximum s Fanout of 10 LS-TTL loads s Simple pulse width formula T = RC s Wide pulse range 400 ns to ∞ typ s Part to part variation ±5% typ s Schmitt Trigger A & B inputs allow rise and fall times to be as slow as one second Ordering Code: Order Number Package Number Package Description MM74HC123AM M16A 16-Lead Small Outline Integrated Circuit SOIC , JEDEC MS-012, Narrow MM74HC123ASJ M16D 16-Lead Small Outline Package SOP , EIAJ TYPE II, 5.3mm Wide MM74HC123AMTC MTC16 16-Lead Thin Shrink Small Outline Package TSSOP , JEDEC MO-153, 4.4mm Wide MM74HC123AN N16E 16-Lead Plastic Dual-In-Line Package PDIP , JEDEC MS-001, Wide Devices also available in Tape and Reel.
