74LVX4245
8-Bit Dual Supply Translating Transceiver with 3-STATE Outputs

General Description

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/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 5V bus; the B Port interfaces with the 3V bus.

The LVX4245 is suitable for mixed voltage applications such as laptop computers using 3.3V CPU's and 5V LCD displays.

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
Guaranteed simultaneous switching noise level and dynamic threshold performance
Implements patented EMI reduction circuitry
Functionally compatible with the 74 series 245
