74LCX374
Low-Voltage Octal D Flip-Flop
with 5V Tolerant Inputs and Outputs
General Description
The LCX374 consists of eight D-type flip-flops featuring sep-
arate D-type inputs for each flip-flop and TRI-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) V_CC applications
with capability of interfacing to a 5V signal environment
The LCX374 is fabricated with an advanced CMOS technol-
ogy to achieve high speed operation while maintaining
CMOS low power dissipation
