Low Voltage 16-Bit Dual Supply Translating Transceiver

with 3-STATE Outputs

General Description

The VCX164245 is a dual supply, 16-bit translating trans-

ceiver that is designed for two way asynchronous commu-

nication between busses at different supply voltages by

providing true signal translation. The supply rails consist of

3.6V and V

1.65V to 2.7V. (V

for proper device operation.) This dual supply design

allows for translation from 1.8V to 2.5V busses to busses at

a higher potential, up to 3.3V.

The Transmit/Receive (T/R) input determines the direction

of data flow. Transmit (active-HIGH) enables data from A

Ports to B Ports. Receive (active-LOW) enables data from

B Ports to A Ports. The Output Enable (OE) input, when

HIGH, disables both A and B Ports by placing them in a

High-Z condition. The A Port interfaces with the lower volt-

age bus (1.8V

higher voltage bus (2.7V

designed so that the control pins (T/R

by V

The 74VCX164245 is suitable for mixed voltage applica-

tions such as notebook computers using a 1.8V CPU and

3.3V peripheral components. It is fabricated with an

Advanced CMOS technology to achieve high speed opera-

tion while maintaining low CMOS power dissipation.

Ordering Code:
