74VCX162245
Low Voltage 16-Bit Bidirectional Transceiver
with 3.6V Tolerant Inputs and Outputs
and 26
: Series Resistors in A Port Outputs
General Description
The VCX162245 contains sixteen non-inverting bidirec-
tional buffers with 3-STATE outputs and is intended for bus
oriented applications. The device is byte controlled. Each
byte has separate 3-STATE control inputs which can be
shorted together for full 16-bit operation. The T/R inputs
determine the direction of data flow through the device.
The OE inputs disable both the A and B ports by placing
them in a high impedance state.
The 74VCX162245 is designed for low voltage (1.4V to
3.6V) VCC applications with I/O compatibility up to 3.6V.
The 74VCX162245 is also designed with 26
: series resis-
tance in the A Port outputs. This design reduces line noise
in applications such as memory address drivers, clock driv-
ers, and bus transceivers/transmitters.
The 74VCX162245 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.

Machine model
!200V
Note 1: To ensure the high-impedance state during power up or power
down, OE should be tied to VCC through a pull-up resistor; the minimum
value of the resistor is determined by the current-sourcing capability of the
driver.
