54F/74F563

Octal D-Type Latch with TRI-STATE Outputs

General Description

The ’F563 is a high-speed octal latch with buffered common

Latch Enable (LE) and buffered common Output Enable

(OE) inputs.

Features

Inputs and outputs on opposite sides of package

allowing easy interface with microprocessors

Useful as input or output port for microprocessors

Functionally identical to ’F573

This device is functionally identical to the ’F573, but has

inverted outputs.
