General Description

The VCX16821 contains twenty non-inverting D-type flipflops with 3-STATE outputs and is intended for bus oriented applications.

The 74VCX16821 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O compatibility up to 3.6V.

The 74VCX16821 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.
