Product Summary

The LTC1387CSW is a low power reconfigurable CMOS bidirectional transceiver. It can be configured as an RS485 differential port or as two RS232 single-ended ports. An onboard charge pump uses four 0.1mF 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 5mA. The applications of the LTC1387CSW include Point-of-Sale Terminals, Software Selectable Multiprotocol Interface Ports, Low Power RS485/RS422/RS232/EIA562 Interface, Cable Repeaters, Level Translators.
