The XD232 is a RoHS-compliant RS232 DIP-16 interface circuit manufactured by XINLUDA. It features signal isolation for improved noise and interference protection and is designed for use in harsh environments such as high voltage automotive applications. It features a CMOS-based design, which conserves power and extends the longevity of the circuit. The XD232 uses a 3-pin TTL interface for configuring the circuit and has a wide-range of associated driver options, such as RS-232 drivers and NPN transistors for driving high-current loads. The integrated isolation voltage is up to 2.25KVrms, protecting the circuit from external interference. Additionally, the circuit features an optimal internal adjustment range, reducing production costs and helping to ensure consistent performance.
