8位双电源转换收发器与3态输出 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.

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
