74VCX16240

Low Voltage 16-Bit Inverting Buffer/Line Driver with

3.6V Tolerant Inputs and Outputs

General Description

The VCX16240 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 74VCX16240 is designed for low voltage (1.65V to

The 74VCX16240 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.
