General Description

The ABT573 is an octal latch with buffered common Latch Enable (LE) and buffered common Output Enable (OE) inputs.

This device is functionally identical to the ABT373 but has broadside pinouts.

Features

■ Inputs and outputs on opposite sides of package allow

easy interface with microprocessors

■ Useful as input or output port for microprocessors

■ Functionally identical to ABT373

■ 3-STATE outputs for bus interfacing

■ Output sink capability of 64mA, source capability of 32mA

■ Guaranteed output skew

■ Guaranteed multiple output switching specifications

■ Output switching specified for both 50pF and 250pF loads

■ Guaranteed simultaneous switching, noise level and

dynamic threshold performance

■ Guaranteed latchup protection

■ High-impedance, glitch-free bus loading during entire

power up and power down

■ Nondestructive, hot insertion capability
