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).

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the
specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
V+ and V– can have maximum magnitudes of 7 V, but their absolute difference cannot exceed 13 V.
