MAX232AEWE+ RS-232 Interface IC

The MAX232AEWE+ from Maxim Integrated is a dual driver/receiver that includes a capacitive voltage generator to supply RS-232 voltage levels from a single 5V supply. This integrated circuit (IC) is designed to meet the stringent specifications of EIA/TIA-232 and V.28/V.24 communications interfaces while being used in applications with limited space that require reliable data transmission.

Each receiver converts RS-232 inputs to 5V TTL/CMOS levels. These receivers have a typical threshold of 1.3V, a typical hysteresis of 0.5V, and can accept ±30V inputs. Furthermore, the receivers can remain in a valid state if up to 25% of the power supply is lost, which makes the MAX232AEWE+ robust in fluctuating power conditions.

The drivers, on the other hand, convert 5V TTL/CMOS levels to RS-232 levels, and they are capable of driving up to 250 kbps. They can handle ±10V output swing with RS-232 load, and they are protected against output short circuits and thermal overloads, ensuring reliability and stability in your communication system.

This IC is available in a 16-pin Wide SO package, making it compact and suitable for space-constrained applications. The MAX232AEWE+ operates in the 0°C to +70°C temperature range, making it versatile for commercial-grade applications.

Key features of the MAX232AEWE+ include:

• Two drivers and two receivers
• Operates from a single 5V power supply
• Capacitive voltage generation for RS-232
• Meets EIA/TIA-232 specifications
• Up to 250 kbps data rate
• ±30V receiver input levels
• Low-power shutdown mode
• 16-pin Wide SO package

With its combination of performance, reliability, and compact form factor, the MAX232AEWE+ is an excellent choice for applications requiring RS-232 communications, such as point-of-sale systems, modems, and various industrial and consumer products.
