74HC573D Octal D-type transparent latch, 3-state, Non-Inverting  DataSheet

Product description

The 74HC573; 74HCT573 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL).

The 74HC573; 74HCT573 has octal D-type transparent latches featuring separate D-type inputs for each latch and 3-state true outputs for bus oriented applications. A latch enable (LE) input and an output enable 1input are common to all latches.

When LE is HIGH, data at the Dn inputs enter the latches. In this condition the latches are transparent, i.e. a latch output will change state each time its corresponding D input changes.

When LE is LOW the latches store the information that was present at the D-inputs a set-up time preceding the HIGH-to-LOW transition of LE. When 1is LOW, the contents of the 8 latches are available at the outputs. When 1is HIGH, the outputs go to the high-impedance OFF-state. Operation of the 1input does not affect the state of the latches.

The 74HC573; 74HCT573 is functionally identical to:
  • 74HC563; 74HCT563, but inverted outputs
  • 74HC373; 74HCT373, but different pin arrangement
Features
  • Inputs and outputs on opposite sides of package allowing easy interface with microprocessors
  • Useful as input or output port for microprocessors and microcomputers
  • 3-state non-inverting outputs for bus oriented applications
  • Common 3-state output enable input
  • Functionally identical to 74HC563; 74HCT563 and 74HC373; 74HCT373
