Functional Description

• Octal Schmitt D-Type Flip-Flop with 3-State Outputs

General

The 74VHCV374FT is an advanced high speed CMOS OCTAL FLIP-FLOP 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 flip-flop is controlled by a clock input (CK) 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 74VHCV374FT

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 (Note) pins

without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and

input/output voltages such as battery back up, hot board insertion, etc.

Note: Output in off-state
