74LVX3245
8-Bit Dual Supply Translating Transceiver 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
■ Bidirectional interface between 3V and 5V buses
■ 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
