TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74HCT573AP,TC74HCT573AF

Octal D-Type Latch with 3-State Output

The TC74HCT573A is a high speed CMOS OCTAL LATCH

technology.

It achieves the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

Its inputs are compatible with TTL, NMOS, and CMOS output

voltage levels.

Its 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 or transient excess voltage.

Features

• Output drive capability: 15 LSTTL loads

• Pin and function compatible with 74LS573
