74ALVC2245
Low Voltage Bidirectional Transceiver
with 3.6V Tolerant Inputs and Outputs
and 26: Series Resistors in B Outputs
General Description
The ALVC2245 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 74ALVC2245 is designed for low voltage (1.65V to
3.6V) V
The ALVC2245 is also designed with 26
in the B Port outputs. This design reduces line noise in
applications such as memory address drivers, clock driv-
ers, and bus transceivers transmitters
The 74ALVC2245 is fabricated with an advanced CMOS
technology to achieve high-speed operation while main-
taining low CMOS power dissipation.

Features
Note 1: To ensure the high impedance state during power up and power
down, OE
value of the resistor is determined by the current sourcing capability of the
driver.
