MAX3232CPWR

The MAX3232CPWR is a Multichannel RS-232 Line Driver/Receiver, dual charge-pump circuit with ±15kV ESD protection terminal to terminal (serial-port connection terminals, 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 to 5.5V supply. The devices operate at data signalling rates up to 250kbps and a maximum of 30V/µs driver output slew rate.

• RS-232 bus terminal ESD protection exceeds ±15kV using human-body model (HBM)
• Meets or exceeds requirements of TIA/EIA-232-F and ITU V.28 standards
• Operates up to 250kbps
• Two drivers and two receivers
• 300µA Typical low supply current
• 4 x 0.1µF External capacitors
• Accepts 5V logic input with 3.3V supply
• Green product and no Sb/Br
