Functional Description

• Low-Voltage Octal D-Type Latch with 5-V Tolerant Inputs and Outputs

General

The 74LCX573FT is a high-performance CMOS octal D-type latch. Designed for use in 3.3-V systems, it achieves

high-speed operation while maintaining the CMOS low power dissipation.

The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5-V supply

environment for both inputs and outputs.

This 8-bit D-type latch is controlled by a latch enable input (LE) and an output enable input (OE).

When the OE input is high, the eight outputs are in a high-impedance state.

All inputs are equipped with protection circuits against static discharge.

Features

1) Low-voltage operation: VCC = 1.65 to 3.6 V

2) High-speed operation: tpd = 8.0 ns (max) (VCC = 3.0 to 3.6 V)

3) Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 to 3.6 V)

4) Power-down protection provided on all inputs and outputs

5) Pin and function compatible with the 74 series

(74LVC/ALVC/ etc.) 573 type
