74LCXZ245
Low Voltage Bidirectional Transceiver
with 5V Tolerant Inputs and Outputs
General Description
The 74LCXZ245 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 74LCXZ245 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation. When V
CC
is between 0V
and 1.5V, the 74LCXZ245 is on the high impedance state
during power up or power down. This places the outputs in
the high impedance (Z) state preventing intermittent low
impedance loading or glitching in bus oriented applications.

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