open-in-new Find other RS-232 transceivers

Description

The TRS3386E is a three-driver and two-receiver RS-232 interface device, with split supply pins for mixed-signal operations. All RS-232 inputs and outputs are protected to ±15 kV using the IEC 61000-4-2 Air-Gap Discharge method, ±8 kV using the IEC 61000-4-2 Contact Discharge method, and ±15 kV using the Human-Body Model.

The charge pump requires only four small 0.1-µF capacitors for operation from a 3.3-V supply. The TRS3386E is capable of running at data rates up to 250 kbps, while maintaining RS-232-compliant output levels.

The TRS3386E has a unique VL pin that allows operation in mixed-logic voltage systems. Both driver in (DIN) and receiver out (ROUT) logic levels are pin programmable through the VL pin. The TRS3386E is available in a space-saving thin shrink small-outline package (TSSOP).

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 (...)
