Dual Non-Retriggerable Monostable Multivibrator
74VHC221A Dual Non-Retriggerable Monostable Multivibrator April 1994 Revised May 1999 74VHC221A Dual Non-Retriggerable Monostable Multivibrator Limits for R and C are: x x General Description External capacitor, C : No limit x The VHC221A is an advanced high speed CMOS Monostable Multivibrator fabricated with silicon gate CMOS External resistors, R : V = 2.0V, 5 kΩ min x CC technology. It achieves the high speed operation similar to V > 3.0V, 1 kΩ min CC equivalent Bipolar Schottky TTL while maintaining the An input protection circuit ensures that 0 to 7V can be CMOS low power dissipation. Each multivibrator features applied to the input pins without regard to the supply volt- both a negative, A, and a positive, B, transition triggered age. This device can be used to interface 5V to 3V systems input, either of which can be used as an inhibit input. Also and two supply systems such as battery back up. This cir- included is a clear input that when taken LOW resets the cuit prevents device destruction due to mismatched supply one-shot. The VHC221A can be triggered on the positive and input voltages. transition of the clear while A is held LOW and B is held HIGH. The VHC221A is non-retriggerable, and therefore cannot be retriggered until the output pulse times out. The Features output pulse width is determined by the equation: � High Speed: t = 8.1 ns (typ) at V = 5V PD CC PW = (Rx)(Cx); where PW is in seconds, R is in ohms, � Low Power Dissipation: I = 4 μA (Max) at T = 25°C CC A and C is in farads. � Active State: I = 600 μA (Max) at T = 25°C CC A � High Noise Immunity: V = V = 28% V (min) NIH NIL CC � Power down protection is provided on all inputs � Pin and function compatible with 74HC221A Ordering Code: Order Number Package Number Package Description 74VHC221AM M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow 74VHC221ASJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74VHC221AMTC MTC16 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 74VHC221AN 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.
