74VCX16374
Low Voltage 16-Bit D-Type Flip-Flop with 3.6V Tolerant
Inputs and Outputs
General Description
The VCX16374 contains sixteen non-inverting D-type flip-
flops with 3-STATE 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 74VCX16374 is designed for low voltage (1.65V to
3.6V) V
CC
applications with I/O compatibility up to 3.6V.
The 74VCX16374 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
