MAX232CPE RS-232 Transceiver Full
The MAX232CPE, developed by Maxim Integrated (now Analog Devices), is a classic dual-channel RS-232 transceiver designed for TTL/CMOS to RS-232 level conversion, housed in a robust 16-pin DIP package for through-hole assembly in legacy and industrial communication systems. Operating from a single +5V supply (4.5V–5.5V), it integrates an on-chip charge pump that generates the ±10V RS-232 voltage levels without requiring external ±12V power supplies, simplifying power supply design. Supporting data rates up to 120kbps, it features two drivers and two receivers, enabling full-duplex asynchronous communication compliant with EIA/TIA-232E and V.28 standards. With a commercial temperature range of 0°C to +70°C, Schmitt trigger inputs for noise immunity, and low power consumption (typically 8mA), it has been a staple in serial interface design for decades.
