74VCX2245 Low Voltage Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs and 26: Series

Resistors in B Outputs

June 1999

Revised April 2005

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)

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.

Note 1:

To ensure the high impedance state during power up and power

down, OE

should be tied to V

through a pull up resistor. The minimum

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

driver.
