54LVX3245

8-Bit Dual Supply Translating Transceiver with

TRI-STATE^®Outputs

General Description

Features

n Bidirectional interface between 3V and 5V buses

n Inputs compatible with TTL level

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 Out-

put Enable input, when HIGH, disables both A and B ports by

placing them in a TRI-STATE condition. The A port interfaces

with the 3V bus; the B port interfaces with the 5V bus.

n 3V data flow at A port and 5V data flow at B port

n Outputs source/sink 24 mA

n Available in ceramic DIP and Flatpack packages

n Implements proprietary EMI reduction circuitry

n Functionally compatible with the 54 series 245

n Standard Microcircuit Drawing (SMD) 5962-9860501

The LVX3245 is suitable for mixed voltage applications such

as systems using 3.3V memories which must interface with

existing busses or other components operating at 5.0V.
