HD74LVC573A Datasheet Octal D-type Transparent Latches with 3-state Outputs

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74LVC573A Octal D-type Transparent Latches with 3-state Outputs ADE-205-116B(Z) 3rd Edition December.

General Description

The HD74LVC573A has eight D type latches with three state outputs in a 20 pin package.

When the latch enable input is high, the Q outputs will follow the D inputs.

When the latch enable goes low, data at the D inputs will be retained at the outputs until latch enable returns high again.
