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.
Wide supply voltage 3V to 5.5V
Hot plug circuitry-Tx and Rx outputs remain three-state during power-up/power-down
Data rate: up to 500Kbps
Full fail-safe (open, short, terminated) receivers
Up to 256 nodes on a bus (1/8 unit load)
Bus-Pin Protection: ±15kV HBM protection
Specified from -40℃ to +85℃
Packaging information: SOP8/MSOP8/DFN8
