We offer RS232 transceivers, RS485 transceivers, and RS422 transceivers

The RS232 interface complies with the interface standard for serial data communication established by the Electronic Industries Alliance (EIA). It has long been popular for computer serial interface peripheral connections, and RS232 transceivers support a data transmission rate to 19200 baud.

The RS485 serial bus is widely used when the communication distance must be several tens of metres to several kilometres. RS485 uses balanced transmitters and differential receivers so that it can reject common-mode interference. A distributed RS485 system can have up to 32 drivers and 32 receivers connected in parallel.

The electrical performance of RS422 transceivers is the same as RS485 transceivers. The main difference is that RS422 has four signal lines: two for transmission and two for receptions. This allows simultaneous reception and transmission (full-duplex).

We offer the popular MAX485 device. This low power transceiver handles RS485 and RS422 communications, and contains one driver and one receiver. The driver slew rates of the MAX485 are not limited, allowing it to transmit at up to 2.5Mbps.

This is part of our broad range of RS232, RS485, and RS422 transceivers from Analog Devices, Renesas, ST Microelectronics, Texas Instruments and other manufacturers. Devices with multiple drivers and multiple receivers are available. Various case styles, supply voltages and operating temperature ranges are supported.
