74VCX162374 Low Voltage 16-Bit D-Type Flip-Flop
74VCX162374
Low Voltage 16-Bit D-Type Flip-Flop
with 3.6V Tolerant Inputs and Outputs
and 26: 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
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 (1.4V to
3.6V) V
CC
applications with I/O compatibility up to 3.6V.
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
down, OE
should be tied to V
CC
through a pull-up resistor; the minimum
value of the resistor is determined by the current-sourcing capability of the
driver.
