RS-485 Half-Duplex Transceivers Detailed Description The MAX14840E/MAX14841E are +3.3V ESD-protected RS-485 transceivers intended for high-speed, half-duplex communications. A hot-swap capability eliminates false transitions on the bus during power-up or hot insertion. The MAX14840E features symmetrical fail-safe and larg- ...
