MAX3232EPE in MAX232 / MAX3232 RS-232 Family
The MAX3232EPE series, manufactured by Analog Devices (Maxim Integrated), is a dual-channel RS-232 transceiver family designed for high-speed serial communication. Operating from a 3.0V to 5.5V supply, these ICs utilize a proprietary low-dropout transmitter output stage and a dual charge pump to maintain true RS-232 performance while minimizing power consumption. They are industry-standard components for bridging the gap between low-voltage microcontrollers and legacy serial peripherals in industrial and commercial hardware designs.
Variants in This Sub-Family
Variants within this sub-family primarily differ by package type, temperature rating, and ESD protection levels. While the MAX3232EPE specifically denotes the 16-pin PDIP package rated for the extended commercial temperature range (0°C to +70°C), sibling variants like the MAX3232EUE or MAX3232ESE offer TSSOP and SOIC footprints. Some 'E' suffix versions also include enhanced ESD protection up to +/-15kV for harsh environments.
