74LCXZ2245 Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs and Outputs and 26: Series

Resistors in B Outputs

October 2000

Revised March 2005

74LCXZ2245

Low Voltage Bidirectional Transceiver

with 5V Tolerant Inputs and Outputs

and 26: Series Resistors in B Outputs

General Description

The LCXZ2245 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

(2.7V and 3.3V) V

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 in the B Port out-

put helps reduce output overshoot and undershoot.

The LCXZ2245 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing CMOS low power dissipation.

When V

is between 0 and 1.5V, the LCXZ2245 is on the

high impedance state during power up or power down. This

places the outputs in the high impedance (Z) state prevent-

ing 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

through a pull-up resistor: the minimum value or the

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