Low Voltage 16-Bit Dual Supply Translating Transceiver

with 3-STATE Outputs

General Description

Features

■ Bidirectional interface between busses ranging from

The VCX163245 is a dual supply, 16-bit translating trans-

ceiver that is designed for 2 way asynchronous communi-

cation between busses at different supply voltages by

providing true signal translation. The supply rails consist of

1.65V to 3.6V

■ Supports Live Insertion and Withdrawal (Note 1)

■ Static Drive (I_OH/I_OL

)

V_CCA, which is a higher potential rail operating at 2.3V to

24 mA @ 3.0V V_CC

18 mA @ 2.3V V_CC

6 mA @ 1.65V V_CC

3.6V and V_CCB, which is the lower potential rail operating at

1.65V to 2.7V. (V_CCBmust be less than or equal to V_CCA

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.

■ Uses patented Quiet Series noise/EMI reduction

circuitry

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 higher volt-

age bus (2.7V to 3.3V); The B Port interfaces with the lower

voltage bus (1.8V to 2.5V). Also the VCX163245 is

designed so that the control pins (T/R_n, OE_n) are supplied

■ Functionally compatible with 74 series 16245

■ Latchup performance exceeds 300 mA

■ ESD performance:

Human Body Model 2000V

Machine model 200V

■ Also packaged in plastic Fine-Pitch Ball Grid Array

(FBGA)

by V_CCB

The 74VCX163245 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.

Note 1: To ensure the high impedance state during power up or power

down, OE should be tied to V

through a pull up resistor. The minimum

CCB

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

driver.
