XD3232 – RS-232 Line Driver/Receiver (Transceiver) – Xinluda

The Xinluda XD3232 is a 3V to 5.5V multichannel RS-232 line driver/receiver with two drivers, two receivers, an on-chip dual charge pump, and ±15kV HBM ESD protection. Available for RFQ through Pacific Component Xchange.

The Xinluda XD3232 is a multichannel RS-232 line driver/receiver designed to provide the electrical interface between an asynchronous communication controller and a serial-port connector. It integrates two line drivers, two line receivers, and a dual charge-pump circuit, enabling full RS-232 operation from a single 3V to 5.5V supply using only four small external 0.1µF capacitors. The device meets or exceeds the requirements of TIA/EIA-232-F and ITU v.28, making it a functional alternative to popular MAX3232-class transceivers.

With ±15kV Human Body Model (HBM) ESD protection on its serial-port pins, the XD3232 is well suited for industrial and external-connector applications where robustness matters. It supports data signaling rates up to 250 kbit/s and accepts 5V logic inputs even when operating from a 3.3V supply, simplifying mixed-voltage designs.
