Evaluation kit (EV kit) circuit demonstrates the RS232/RS485/RS422 multiprotocol transceivers using the MAX3161E IC. The circuit can be configured to operate as a dual transceiver in RS232 mode or as a single transceiver in RS485/RS422 mode. The MAX3161E RS232 data rates can reach 1Mbps while RS485/RS422 data rates can reach 10Mbps. The configurable slew rate limiting feature reduces data rates for either protocol to achieve reduced EMI. In RS485/RS422 mode the EV kit demonstrates full-duplex or half-duplex communication. The MAX3161E drivers feature short-circuit and thermal protection as well as fail-safe circuitry for open, shorted, or unconnected RS485/RS422 receiver inputs.
Operates from a single 3V to 5.5VDC supply capable of providing 100mA
