74VHC374
Octal D-Type Flip-Flop with 3-STATE Outputs
April 2007
tm
Features
■ High Speed: tPD = 5.4ns (typ) at VCC = 5V
■ High noise immunity: VNIH = VNIL = 28% VCC (Min.)
■ Power down protection is provided on all inputs
■ Low power dissipation: ICC = 4µA (Max) @ TA = 25°C
■ Pin and function compatible with 74HC374
General Description
The VHC374 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.
An input protection circuit ensures that 0V to 7V can be
applied to the input pins without regard to the supply
voltage. This device can be used to interface 5V to 3V
systems and two supply systems such as battery back
up. This circuit prevents device destruction due to mis-
matched supply and input voltages.
