DESCRIPTION/ORDERING INFORMATION
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).
