Dual Retriggerable Monastable Multivibrator
74VHC123A Dual Retriggerable Monostable Multivibrator July 1993 Revised April 1999 74VHC123A Dual Retriggerable Monostable Multivibrator An input protection circuit ensures that 0 to 7V can be General Description applied to the input pins without regard to the supply volt- The VHC123A is an advanced high speed CMOS age. This device can be used to interface 5V to 3V systems Monostable Multivibrator fabricated with silicon gate CMOS and two supply systems such as battery back up. This cir- technology. It achieves the high speed operation similar to cuit prevents device destruction due to mismatched supply equivalent Bipolar Schottky TTL while maintaining the and input voltages. CMOS low power dissipation. Each multivibrator features both a negative, A, and a positive, B, transition triggered Features input, either of which can be used as an inhibit input. Also included is a clear input that when taken low resets the � High Speed: one-shot. The VHC123A can be triggered on the positive t = 8.1 ns (typ) at T = 25°C PD A transition of the clear while A is held low and B is held high. � Low Power Dissipation: The output pulse width is determined by the equation: I = 4 μA (Max) at T = 25°C PW = (R )(C ); where PW is in seconds, R is in ohms, and CC A x x C is in farads. � Active State: I = 600 μA (Max) at T = 25°C CC A Limits for R and C are: x x � High Noise Immunity: V = V = 28% V (min) NIH NIL CC External capacitor, C No limit x � Power down protection is provided on all inputs External resistors, R V = 2.0V, 5 kΩ min � Pin and function compatible with 74HC123A x CC V > 3.0V, 1 kΩ min CC Ordering Code: Order Number Package Number Package Description 74VHC123AM M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150” Narrow 74VHC123ASJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74VHC123AMTC MTC16 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 74VHC123AN N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide Surface mount packages are also available on Tape and Reel.
