74VHCT374A Rev. 1.3

74VHCT374A

Octal D-Type Flip-Flop with 3-STATE Outputs

Features

■ High speed: fMAX = 140MHz (Typ.) at TA = 25°C

■ High noise immunity: VIH = 2.0V, VIL = 0.8V

■ Power down protection is provided on all inputs and

outputs

■ Low power dissipation: ICC = 4µA (Max.) @ TA = 25°C

■ Pin and function compatible with 74HCT374

General Description

The VHCT374A 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 main-

taining the CMOS low power dissipation. This 8-bit

D-type flip-flop is controlled by a clock input (CP) and an

output enable input (OE). When the OE input is HIGH,

the eight outputs are in a high impedance state.

Protection circuits ensure that 0V to 7V can be applied to

the input and output(1) pins without regard to the supply

voltage. This device can be used to interface 3V to 5V

systems and two supply systems such as battery back

up. This circuit prevents device destruction due to mis-

matched supply and input voltages.

Note:

1. Outputs in OFF-State.

Ordering Information

Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the

ordering number. Pb-Free package per JEDEC J-STD-020B.
