open-in-new Find other RS-232 transceivers

Description

The TRSF3232E consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection pin to pin (serial-port connection pins, including GND). This device provides the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V supply. The TRSF3232E operates at data signaling rates up to 1 Mbit/s and a driver output slew rate of 14 V/µs to 150 V/µs.

Reference Design for Converting RS-232 Signaling to RS-485 Signaling
TIDA-060008 — This reference design provides a circuit of converting RS-232 signaling to RS-485 signaling. This allows for long-distance communication, since the range supported by RS-232 is normally less than 50 feet while the range for RS-485's can exceed 1000 feet. The design implements bidirectional (...)
