74VCX16721
Low Voltage 20-Bit D-Type Flip-Flops with 3.6V Tolerant
Inputs and Outputs
General Description
The VCX16721 contains twenty non-inverting D-type flip-
flops with 3-STATE outputs and is intended for bus oriented
applications.
The 74VCX16721 is designed for low voltage (1.65V to
3.6V) V
CC
applications with I/O compatibility up to 3.6V.
The 74VCX16721 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
