1. Describe
The MAX3232IPWR device consists of two line drivers, two line receivers, and a dual charge pump circuit with ±15 kV ESD protection pin-to-pin (serial port connections, including GND). The device is TIA/EIA-232-F compliant and provides the electrical interface between the asynchronous communication controller and the serial port connector. A charge pump and four small external capacitors allow operation from a single 3V to 5.5V supply. The devices operate at data signaling rates up to 250 kbit/s and driver output slew rates up to 30-V/μs.
