MC74LVX373
Octal D-Type Latch
with 3-State Outputs
With 5V−Tolerant Inputs
The MC74LVX373 is an advanced high speed CMOS octal latch
with 3−state outputs. The inputs tolerate voltages up to 7.0 V, allowing
the interface of 5.0 V systems to 3.0 V systems.
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.
Features
• High Speed: t
PD
= 5.8 ns (Typ) at V
CC
= 3.3 V
• Low Power Dissipation: I
CC
= 4 mA (Max) at T
A
= 25°C
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Low Noise: V
OLP
= 0.8 V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300 mA
• ESD Performance:
Human Body Model > 2000 V;
Machine Model > 200 V
• These Devices are Pb−Free and are RoHS Compliant
