Product Summary

The 74HC573 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). The 74HC573 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 (OE) input are common to all latches.

Parametrics

74HC573 absolute maximum ratings: (1)VCC supply voltage: 2.0 to 6.0 V; (2)Tamb ambient temperature: -40 +25 +125 ℃; (3)VCC supply voltage: -0.5 +7 V; (4)ICC quiescent supply current: 70 mA; (5)IGND ground current: -70 mA.

Features

74HC573 features: (1)Inputs and outputs oopposite sides of package allowing easy interface with microprocessors; (2)Useful as input or output port for microprocessors and microcomputers; (3)3-state non-inverting outputs for bus oriented applications; (4)Commo3-state output enable input; (5)Functionally identical to 74HC563; 74HCT563 and 74HC373; 74HCT373; (6)Complies with JEDEC standard no. 7A.
