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).
