74LVX3245
8-Bit Dual Supply TranslatingTransceiver with 3-STATE Outputs

General Description

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.

The LVX3245 is suitable for mixed voltage applications such as notebook computers using 3.3V CPU and 5V peripheral components.

Features

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
