Functional Description

• Hex D-Type Flip-Flop with Clear

General

The 74VHC174FT is an advanced high speed CMOS HEX D-TYPE FLIP FLOP fabricated with silicon gate

C2MOS technology.

It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS

low power dissipation.

Information signals applied to D inputs are transferred to the Q output on the positive going edge of the clock pulse.

When the CLR input is held low, the Q output are in the low logic level independent of the other inputs.

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.
