Description
The SP3485E is a 3.3V powered, half-duplex, low-power RS-485 transceiver that fully meets the requirements of the TIA/EIA-485 standard.
The SP3485E includes a driver and a receiver, both of which can be independently enabled and disabled. When both are disabled, both the driver and the receiver output a high impedance state. The SP3485E has a 1/8 load that allows 256 SP3485E transceivers to be connected to the same munication bus. Error-free data transfer of up to 12Mbps is possible.
The SP3485E operates from a voltage range of 3.0 to 3.6V and features fail-safe,...
