STC3232E
High ESD-Protected, Low Power, 3.3V to 5.5V, True RS-232 Transceivers
General Description
The STC3232E is 2 driver, 2 receiver RS-232 transceiver solutions intended for portable or hand-held applications, 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.
