Octal D-Type Latch with 3-State Output

LATCH with 3-STATE OUTPUT fabricated with silicon gate

Bipolar Schottky TTL while maintaining the CMOS low power

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

•

The TC74VHC373 is an advanced high speed CMOS OCTAL

It achieves the high speed operation similar to equivalent

This 8-bit D-type latch is controlled by a latch enable input

When the OE input is high, the eight outputs are in a high

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