General Description

The 74AC573 and 74ACT573 are high-speed octal latches with buffered common Latch Enable (LE) and buffered common Output Enable (OE) inputs.

The 74AC573 and 74ACT573 are functionally identical to the 74AC373 and 74ACT373 but with inputs and out puts on opposite sides.

Features

■ ICC and IOZ reduced by 50

■ Inputs and outputs on opposite sides of package

allowing easy interface with microprocessors

■ Useful as input or output port for microprocessors

■ Functionally identical to 74AC373 and 74ACT373

■ 3-STATE outputs for bus interfacing

■ Outputs source/sink 24mA

■ 74ACT573 has TTL-compatible inputs
