Philips 74HC573D D Type Transparent Non-Inverting Latch SMT / SMD SO-20

The 74HC573; 74HCT573 is an 8-bit D-type transparent latch with 3-state outputs. The device features latch enable (LE) and output enable (OE) inputs. When LE is HIGH, data at the inputs enter the latches. In this condition the latches are transparent, a latch output will change each time its corresponding D-input changes. When LE is LOW the latches store the information that was present at the inputs a set-up time preceding the HIGH-to-LOW transition of LE. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not affect the state of the latches. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

The 74HC573D is a high speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL). The 74HC573D 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 input and an output enable input are common to all latches.
