MC74VHC373
Octal D-Type Latch with 3-State Output
The MC74VHC373 is an advanced high speed CMOS octal latch with 3−state output fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining CMOS low power dissipation.
This 8−bit D−type latch is controlled by a latch enable input and an output enable input. When the output enable input is high, the eight outputs are in a high impedance state.
The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. The inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V systems to 3.0 V systems.
Features
High Speed: tPD = 5.0 ns (Typ) at VCC = 5.0 V Low Power Dissipation: ICC = 4.0 mA (Max) at TA = 25°C High Noise Immunity: VNIH = VNIL = 28% VCC Power Down Protection Provided on Inputs Balanced Propagation Delays Designed for 2.0 V to 5.5 V Operating Range Low Noise: VOLP = 0.9 V (Max) Pin and Function Compatible with Other Standard Logic Families Latchup Performance Exceeds 300 mA ESD Performance: HBM > 2000 V; Machine Model > 200 V Chip Complexity: 186 FETs or 46.5 Equivalent Gates These Devices are Pb−Free and are RoHS Compliant
