Octal D-Type Latch with 3-State Output

The TC74VHC373 is an advanced high speed CMOS OCTAL

LATCH with 3-STATE OUTPUT fabricated with silicon gate

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

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 5.5 V can be

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

This device can be used to interface 5 V to 3 V 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 is provided on all inputs.

• Pin and function compatible with 74ALS373
