The Texas Instruments MAX202IDR is a highly integrated dual-channel RS-232 line driver and receiver designed to provide the electrical interface between asynchronous digital communication controllers and RS-232 serial ports.
The device integrates two line drivers, two line receivers and a dual charge-pump circuit, allowing RS-232 signal levels to be generated from a single 5V power supply. Only four small external capacitors are required for operation, helping simplify board design and reduce external component count.
MAX202IDR supports data signaling rates up to 120kbps and provides a typical driver output voltage of approximately ±9V. The maximum driver output slew rate is 30V/µs, providing reliable performance for standard RS-232 serial communications.
The RS-232 bus pins provide ±15kV Human Body Model (HBM) ESD protection, improving robustness against electrostatic discharge in serial-port applications. The device meets or exceeds the requirements of TIA/EIA-232-F and ITU V.28 interface standards.
The MAX202IDR industrial-temperature version operates from -40°C to +85°C and is supplied in a 16-pin SOIC (D) package. The R suffix indicates tape-and-reel packaging for automated SMT production.
