74HC573 IC Octal D-Type Latch with 3-State Output DIP-20 74HC573

Product Overview

The 74HC573 is an 8-bit D-type transparent latch featuring 3-state outputs. It includes a latch enable (LE) input and an output enable (OE) input. When the LE input is HIGH, the device is transparent, meaning the Q outputs follow the data (D) inputs directly. When LE transitions to LOW, the device stores the information present at the D inputs immediately preceding that transition. The 3-state outputs allow the device to be used effectively in bus-oriented systems, as the OE input can place the outputs into a high-impedance (OFF) state without affecting the stored data within the latches.
