54LCX16374 Low Voltage 16-Bit D Flip-Flop with 5V Tolerant Inputs and Outputs
July 1999
54LCX16374
Low Voltage 16-Bit D Flip-Flop with 5V Tolerant Inputs
and Outputs
General Description
The LCX16374 contains sixteen non-inverting D flip-flops
with TRI-STATE
廬
outputs and is intended for bus oriented
applications. The device is byte controlled. A buffered clock
(CP) and Output Enable (OE) are common to each byte and
can be shorted together for full 16-bit operation.
The LCX16374 is designed for low voltage (3.3V) V
CC
appli-
cations with capability of interfacing to a 5V signal environ-
ment.
The LCX16374 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
