DM74LS573

Octal D-Type Latch with 3-STATE Outputs

General Description

The DM74LS573 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 allow-

ing easy interface with microprocessors

■ Useful as input or output port for microprocessors

■ Functionally identical to DM74LS373

This device is functionally identical to the DM74LS373, but

has different pinouts.

■ Input clamp diodes limit high speed termination effects

■ Fully TTL and CMOS compatible
