The AM26LS31CD with RS-422 Interface IC Quad Diff is a quad differential line receiver manufactured by Texas Instruments. It is designed to provide an isolated low power logic interface between two systems. It is capable of transmitting and receiving data in unbalanced, low noise environments. It has two independent channels, allowing for independent data streaming. It has a differential input and output, aiding in reduced EMI emissions and superior signal integrity. The input tolerance is 500 mV and it has an output current of 4 mA. It is functioning over a wide voltage range of 3V to 15V and a wide temperature range of 0°C to 70°C. It has high performance features, such as low input offset voltage drift, low input bias current, and low output offset voltage, making it well suited for RS-422 interface applications.
