MAX3160 RS-232/RS-485/422 Multiprotocol Transceiver Evaluation Kit

The MAX3160E evaluation kit (EV kit) circuit demonstrates the RS-232/RS-485/RS-422 multiprotocol transceivers using the MAX3160E IC. The circuit can be configured to operate as a dual transceiver in RS-232 mode or as a single transceiver in RS-485/RS-422 mode. The MAX3160E RS-232 data rates can reach 1Mbps, while RS-485/RS-422 data rates can reach 10Mbps. The configurable slew-rate limiting feature reduces data rates for either protocol to achieve reduced EMI. In RS-485/RS-422 mode, the EV kit demonstrates full-duplex or half-duplex communication. The MAX3160E drivers feature short-circuit and thermal protection as well as fail-safe circuitry for open, shorted, or unconnected RS-485/RS-422 receiver inputs. The MAX3160E EV kit operates from a single 3V to 5.5VDC supply capable of providing 100mA.
