MAX3232 Datasheet – RS-232 Line Driver/Receiver – TI

Part Number : MAX3232, MAX3232IDW

Function : 3-V to 5.5-V Multichannel RS-232 Line Driver/Receiver

Package : SOIC, SSOP, TSSOP 16 Pin type

Manufactures : Texas Instruments



Description :

The MAX3232 device consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV 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-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.
