The MAX232CPE-C70055 is a dual driver/receiver that includes a capacitive voltage generator to supply RS-232 voltage levels from a single 5V supply. Manufactured by Maxim Integrated, this IC is designed to interface with the standards of EIA/TIA-232 and V.28/V.24 communications interfaces which are commonly used in serial communications protocols.

This device features two drivers and two receivers, making it an ideal choice for serial data exchange for modems, printers, and various other peripheral devices that utilize RS-232 protocol. Each receiver converts RS-232 inputs to 5V TTL/CMOS levels, and each driver converts 5V TTL/CMOS input levels to RS-232 output levels.

The MAX232CPE-C70055 is equipped with a unique charge pump circuit that allows for operation from a single 5V supply while maintaining RS-232 output levels. This circuit eliminates the need for the multiple power supplies typically required by RS-232 transceivers, thereby simplifying design and reducing board space requirements.

The IC is packaged in a 16-pin DIP (Dual In-line Package), making it convenient for breadboard prototyping and production PCBs alike. Its robust design allows for data rates up to 120 kbps and ensures reliable communication even under harsh conditions. Additionally, the MAX232CPE-C70055 features ±30V input levels, low supply current, and an efficient power-saving shutdown mode.

Its wide range of applications includes but is not limited to industrial controls, point-of-sale systems, and data acquisition systems. The MAX232CPE-C70055 provides a reliable and cost-effective solution for establishing RS-232 communication in a variety of electronic projects and commercial products.

Maxim Integrated's commitment to quality ensures that the MAX232CPE-C70055 meets the stringent requirements of modern electronic communication standards, offering designers a versatile and dependable interface solution.
