General Description

The VCX162835 low voltage 18-bit universal bus driver combines D-type latches and D-type flip-flops to allow data flow in transparent, latched and clocked modes.

The VCX162835 is designed with 26Ω series resistors in the outputs. This design reduces noise in applications such as memory address drivers, clock drivers, and bus transceivers/transmitters.

The 74VCX162835 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O capability up to 3.6V.

The 74VCX162835 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.
