MAX3232EIPWR

Provides ESD protection for RS-232 bus pins. The MAX3232E device consists of two line drivers, two line receivers, and a dual charge pump circuit, featuring ±15kV IEC ESD protection pin-to-pin (serial port connection pins, including GND). The device meets TIA/EIA-232-F requirements and provides the electrical interface between asynchronous communication controllers and serial port connectors. The charge pump and four small external capacitors enable operation from a single 3V to 5.5V power supply. The device operates at data signaling rates up to 250kbit/s, with a maximum driver output slew rate of 30V/μs.
