Low-Power 500Kbps Full Fail-Safe RS-485 Transceiver

The AiP485B is 3V~5.5V powered transceiver that meets the RS-485 standards for balanced communication.

This transceiver delivers at least a 2.1V differential output voltage on 5V supply condition, into the RS-485 required 54Ω load, for better noise immunity. This 500Kbps device has very low bus currents so that presents a true “1/8 unit load” to the RS-485 bus. This allows up to 256 transceivers on the network without using repeaters.

Receiver (Rx) inputs feature a “Full Fail-Safe” design, which ensures a logic high Rx output if Rx inputs are floating, shorted, or on a terminated but undriven bus.
