74VCX2245
Low Voltage Bidirectional Transceiver
with 3.6V Tolerant Inputs and Outputs
and 26 Series Resistors in B Outputs
General Description
The VCX2245 contains eight non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus ori-
ented applications. The T/R input determines the direction
of data flow. The OE input disables both the A and B ports
by placing them in a high impedance state.
The 74VCX2245 is designed for low voltage (1.4V to 3.6V)
V
CC
applications with I/O compatibility up to 3.6V. The
VCX2245 is also designed with 26
:
series resistance in
the B Port outputs. This design reduces line noise in appli-
cations such as memory address drivers, clock drivers, and
bus transceivers transmitters
The 74VCX2245 is fabricated with an advanced CMOS
technology to achieve high-speed operation while main-
taining low CMOS power dissipation.

value of the resistor is determined by the current sourcing capability of the
driver.
