Features

low power consumption, high data-rate capabilities, and enhanced ESD protection. The ESD tolerance of the STC3232E devices is over ± 15kV for both human body model and IEC1000-4-2 air discharge test methods. A low-dropout transmitter output stage delivers true RS-232 performance from a +3.0V to +5.5V power supply, using an internal dual charge pump. The charge pump requires only four small 0.1µ F capacitors for operation from a +3.3V supply. Each device guarantees operation at data rates of 250kbps while maintaining RS-232 output levels. The STC3232E is pin, package, and functionally compatibl.
