Features and Benefits

  • 3V to 5.5V Single-Supply Operation
  • Configurable Multiprotocol Operation:
    • 2Tx/2Rx RS-232 Transceivers
    • Single RS-485/RS-422 Transceiver
  • 10Mbps RS-485/RS-422 Data Rates and 1Mbps RS-232 Data Rates
  • Configurable RS-232/RS-485 Transmitter Slew Rates
  • Configurable Full-Duplex/Half-Duplex RS-485/RS-422 Operation
  • Fully Assembled and Tested

Product Details

The MAX3161E evaluation kit (EV kit) circuit demonstrates the RS-232/RS-485/RS-422 multiprotocol transceivers using the MAX3161E 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 MAX3161E 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 MAX3161E 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 MAX3161E EV kit operates from a single 3V to 5.5VDC supply capable of providing 100mA.

Applications

  • Industrial Controls
  • Interface Converters
  • Networking
  • Peripherals
  • Point-of-Sale Equipment
  • RS-232 to RS-485
  • Security Systems
