The charge pump requires only four small 0.1-F 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). ORDERING INFORMATION
