MAX3232ECDBRE4

3V至5.5V多通道RS - 232线路驱动器/接收器【 15千伏IEC ESD保护 3-V TO 5.5-V MULTICHANNEL RS-232 LINE DRIVER/RECEIVER WITH 【15-kV IEC ESD PROTECTION

DESCRIPON

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.
