74LCXR2245
Low Voltage Bidirectional Transceiver with
5V Tolerant Inputs and Outputs and
26
Series Resistors on Both A and B Ports
General Description
The LCXR2245 contains eight non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus ori-
ented applications. The device is designed for low voltage
(2.5V and 3.3V) V
CC
applications with capability of interfac-
ing to a 5V signal environment. The T/R input determines
the direction of data flow through the device. The OE input
disables both the A and B ports by placing them in a high
impedance state. The 26
series resistor helps reduce
output overshoot and undershoot.
The LCXR2245 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.

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