LTC1387CG#TRPBF

The LTC1387CG#TRPBF is a versatile, low-power, reconfigurable CMOS bidirectional transceiver from Analog Devices. It can function as either an RS485 differential port or two RS232 single-ended ports, making it suitable for a wide range of communication needs. This device operates from a single 5V supply and features an onboard charge pump to generate the necessary voltage levels for RS232 drivers, meeting -5V output swing requirements.

Key electrical specifications include a 5V operating voltage, a data rate of 150KBd, and receiver hysteresis of 40mV. It supports multiprotocol communication and operates in half-duplex mode. The transceiver is designed with features such as short-circuit and thermal shutdown protection for its drivers. The RS485 receiver guarantees a known output state even when inputs are floating or shorted to ground.

Packaged in a 20-SSOP (0.209", 5.30mm Width) surface mount configuration, the LTC1387CG#TRPBF is designed for efficient integration into various electronic systems. Its operating temperature range is 0°C to 70°C. The device supports separate driver and receiver enable controls, and the driver maintains high impedance in three-state, shutdown, or power-off conditions, enhancing system flexibility and protection.

Applications for this transceiver include point-of-sale terminals, cable repeaters, and level translators, where reliable and flexible serial communication is essential. Its ability to switch between RS232 and RS485 protocols simplifies system design and reduces component count.
