74LVX4245

8-Bit Dual Supply Translating Transceiver

with TRI-STATE Outputs

General Description

Features

Bidirectional interface between 5V and 3V buses

Control inputs compatible with TTL level

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

Outputs source/sink 24 mA at 5V bus; 12 mA at 3V

bus

The LVX4245 is a dual-supply, 8-bit translating transceiver

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

in a mixed 3V/5V supply environment. The Transmit/Re-

ceive (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 Z condition. The A

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

the 3V bus.

Guaranteed simultaneous switching noise level and dy-

namic threshold performance

Available in SOIC, QSOP and TSSOP packages

Implements patented Quiet Series EMI reduction

circuitry

The LVX4245 is suitable for mixed voltage applications such

as laptop computers using 3.3V CPU’s and 5V LCD dis-

plays.

Functionally compatible with the 74 series 245
