74LVX3245

8-Bit Dual Supply Translating Transceiver with

3-STATE Outputs

General Description

Features

■ Bidirectional interface between 3V and 5V buses

The LVX3245 is a dual-supply, 8-bit translating transceiver

that is designed to interface between a 3V bus and a 5V

bus in a mixed 3V/5V supply environment. 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 input, when HIGH, disables

both A and B Ports by placing them in a high impedance

condition. The A Port interfaces with the 3V bus; the B Port

interfaces with the 5V bus.

■ Inputs compatible with TTL level

■ 3V data flow at A Port and 5V data flow at B Port

■ Outputs source/sink 24 mA

■ Guaranteed simultaneous switching noise level and

dynamic threshold performance

■ Implements proprietary EMI reduction circuitry

■ Functionally compatible with the 74 series 245

The LVX3245 is suitable for mixed voltage applications

such as notebook computers using 3.3V CPU and 5V

peripheral components.
