74VCX162374

Low Voltage 16-Bit D-Type Flip-Flop

with 3.6V Tolerant Inputs and Outputs

and 26

Ω Series Resistors in Outputs

General Description

The VCX162374 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 VCX162374 is also designed with 26

Ω series resistors

in the outputs. This design reduces line noise in applica-

tions such as memory address drivers, clock drivers and

bus transceivers/transmitters.

The 74VCX162374 is designed for low voltage (1.65V to

The 74VCX162374 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.

Note 1: To ensure the high-impedance state during power up or power

value of the resistor is determined by the current-sourcing capability of the

driver.
