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.

space-saving thin shrink small-outline package (TSSOP).
