MAX3232CPE in MAX232 / MAX3232 RS-232 Family
The MAX3232CPE family, manufactured by Maxim Integrated (now Analog Devices), comprises high-performance RS-232 transceivers designed for 3.0V to 5.5V operation. These devices utilize a proprietary dual charge-pump structure that allows true RS-232 performance from a single low-voltage supply while maintaining compatibility with legacy 5V logic. They are primarily used to bridge the gap between TTL/CMOS microcontrollers and standard RS-232 serial ports in communication systems where low power consumption and small footprint are critical.
Variants in This Sub-Family
Variants within this family are primarily distinguished by their operating temperature ranges and package types. The 'CPE' suffix denotes a 16-pin Plastic DIP package rated for the commercial temperature range of 0°C to +70°C. Other variants, such as the EPE or CSE, offer industrial temperature ratings (-40°C to +85°C) or surface-mount form factors like SOIC and TSSOP to accommodate different thermal environments and manufacturing requirements.
