MC74VHC373
Octal DType Latch
with 3State Output
The MC74VHC373 is an advanced high speed CMOS octal latch
with 3state 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 8bit Dtype 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.
High Speed: t
PD = 5.0 ns (Typ) at VCC = 5.0 V
Low Power Dissipation: I
CC = 4.0
mA (Max) at TA = 25°C
High Noise Immunity: V
NIH = 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: V
OLP = 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
