●ESD protection for RS-232 bus pins ○±15 kV (HBM) ○±8 kV (IEC61000-4-2, Contact discharge) ○±15 kV (IEC61000-4-2, Air-gap discharge) ●Meets or exceeds the requirements of TIA/EIA-232-F and ITU V.28 standards ●Operates with 3-V to 5.5-V V_CC supply ●Operates up to 250 kbit/s ●Two drivers and two receivers ●Low supply current: 300 µA (typical) ●External capacitors: 4 × 0.1 µF ●Accepts 5-V logic input with 3.3-V supply ●Pin compatible to alternative high-speed devices (1 Mbit/s) ○SN65C3232E (–40°C to +85°C) ○SN75C3232E (0°C to 70°C)The MAX3232E device consists of two line drivers, two-line receivers, and a dual charge-pump circuit with ±15-kV IEC ESD protection pin to pin (serial-port connection pins, including GND). The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V supply. The devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/µs driver output slew rate.
