74LCX374
Low Voltage Octal D-Type Flip-Flop
with 5V Tolerant Inputs and Outputs
General Description
The LCX374 consists of eight D-type flip-flops featuring
separate D-type inputs for each flip-flop and 3-STATE out-
puts for bus-oriented applications. A buffered clock (CP)
and Output Enable (OE) are common to all flip-flops. The
LCX374 is designed for low voltage (3.3V or 2.5V) V
CC
applications with capability of interfacing to a 5V signal
environment.
The LCX374 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.

To ensure the high-impedance state during power up or down, OE
should be tied to V

through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.
