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 7V, allowing the interface of 5V systems to 3V systems.

•

High Speed: tPD = 5.0ns (Typ) at VCC = 5V

Low Power Dissipation: ICC = 4µA (Max) at TA = 25°C

High Noise Immunity: VNIH = VNIL = 28% VCC

Power Down Protection Provided on Inputs

Balanced Propagation Delays

Designed for 2V to 5.5V Operating Range

Low Noise: VOLP = 0.9V (Max)

Pin and Function Compatible with Other Standard Logic Families

Latchup Performance Exceeds 300mA

ESD Performance: HBM > 2000V; Machine Model > 200V

Chip Complexity: 186 FETs or 46.5 Equivalent Gates
