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 (1.4V to
3.6V) V
The 74VCX16721 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
