DESCRIPTION/ORDERING INFORMATION

The MAX3386E 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 MAX3386E is

capable of running at data rates up to 250 kbps, while maintaining RS-232-compliant output levels.

The MAX3386E 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 MAX3386E is available in a

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