Octal D-Type Flip-Flop with 3-STATE Outputs
May 2007
tm
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.
