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.
