Octal Schmitt D-Type Latch with 3-State Output

The TC74VHCV373 is an advanced high speed CMOS OCTAL

LATCH with 3-STATE OUTPUT fabricated with silicon gate

CMOS technology.

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.

Input pin have hysteresis between the positive-going and

negative-going thresholds. Thus the TC74VHCV373 are capable

of squaring up transitions of slowly changing input signals and

provides an improved noise immunity.

Input protection and output circuit ensure that 0 to 5.5 V can be

applied to the input and output

supply voltage. These structure prevents device destruction due

to mismatched supply and input/output voltages such as battery

back up, hot board insertion, etc.
