74VCX162240
Low Voltage 16-Bit Inverting Buffer/Line Driver with 3.6V
Tolerant Inputs and Outputs and 26
Series Resistors in
Outputs
General Description
The VCX162240 contains sixteen inverting buffers with 3-
STATE outputs to be employed as a memory and address
driver, clock driver, or bus oriented transmitter/receiver.
The device is nibble (4-bit) controlled. Each nibble has sep-
arate 3-STATE control inputs which can be shorted
together for full 16-bit operation.
The 74VCX162240 is designed for low voltage (1.65V to
3.6V) V
CC
applications with I/O capability up to 3.6V. The
74VCX162240 is also designed with 26
series resistors in
the outputs. This design reduces line noise in applications
such as memory address drivers, clock drivers, and bus
transceivers/transmitters.
The 74VCX162240 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.

through a pull-up resistor; the minimum
value of the resistor is determined by the current-sourcing capability of the
driver.
