ST3293 is a high-speed RS-422 transceiver from STMicroelectronics. It supports data rates up to 25Mbps and features a digitally programmable voltage amplifier. The device also supports short circuit current limiting and open circuit fault protection.
The ST3293 is a high-speed RS-422 transceiver featuring an emphasis circuitry on the driver. This design allows for reliable long-distance communication at high data rates by reducing inter-symbolic interference. The differential amplitude of the device is digitally programmable in seven steps through three control pins, and it operates from a single +5V supply.
