Product Overview

The LTC1387CSW#PBF is a low power reconfigurable CMOS bidirectional Multiprotocol Transceiver can be configured as an RS485 differential port or as two RS232 single-ended ports. An onboard charge pump uses four 0.1µF capacitors to generate boosted positive and negative supplies, allowing the RS232 drivers to meet ±5V output swing requirements with only a single 5V supply. A shutdown mode reduces the ICC supply current to 5µA. The RS485 receiver assumes a known output state when the inputs are floating or shorted to ground. All interface drivers feature short-circuit and thermal shutdown protection. An enable pin allows RS485 driver outputs to be forced into high impedance which is maintained even when the outputs are forced beyond supply rails or the power is OFF. A loop back mode allows the driver outputs to be connected back to the receiver inputs for diagnostic self-test.
  • Guaranteed receiver output with inputs floating or shorted to ground
  • Logic selectable fast/slow RS485 driver slew rate
  • Self-testing capability in loopback mode
  • Separate driver and receiver enable controls
  • Driver maintains high impedance in three-state, shutdown or with power OFF
  • Receiver inputs can withstand ±25V
