Octal D-Type Latch with 3-State Output

The TC74LVX573F/ FT is a high-speed CMOS octal latch with

3-state output fabricated with silicon gate CMOS technology.

Designed for use in 3-V systems, it achieves high-speed operation

while maintaining the CMOS low power dissipation.

This device is suitable for low-voltage and battery operated

systems.

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.

An input protection circuit ensures that 0 to 5.5V can be

applied to the input pins without regard to the supply voltage.

This device can be used to interface 5V to 3V systems and two

supply systems such as battery back up. This circuit prevents

device destruction due to mismatched supply and input voltages.

Features

• Power-down protection provided on all inputs

• Pin and function compatible with 74HC573
