MAX232EWE-T from Maxim Integrated
The MAX232EWE-T is a highly-reliable, dual driver/receiver device from Maxim Integrated, designed to facilitate serial communication in electronic systems. This integrated circuit is part of the MAX232 series and is specifically engineered to convert TTL or CMOS logic levels to RS-232 and vice versa, making it an essential component for applications requiring serial port communication.
Constructed with Maxim Integrated's advanced technology, the MAX232EWE-T offers improved specifications and performance compared to its predecessors. This device operates with a supply voltage ranging from 4.5V to 5.5V, which is typical for many digital systems, ensuring compatibility with a wide range of microcontrollers and digital logic families.
Featuring two drivers and two receivers, this versatile IC can support the full-duplex communication necessary for a standard RS-232 interface. The MAX232EWE-T is capable of generating the necessary RS-232 voltage levels (±7.5V minimum) from a single 5V power supply, thanks to its onboard charge pump circuitry. This eliminates the need for additional power supplies, simplifying design and reducing board space.
The MAX232EWE-T is housed in a 16-pin wide SOIC (Small Outline Integrated Circuit) package, making it suitable for space-constrained applications. Its industrial temperature range of -40°C to +85°C ensures reliable operation under harsh environmental conditions.
Key features of the MAX232EWE-T include:
- Two drivers and two receivers for full-duplex communication
- Onboard charge pump circuitry for RS-232 voltage level generation
- Compatible with 5V power supply
- Low supply current of 8mA typical
- ESD protection up to ±15kV
- Meets or exceeds TIA/EIA-232-F and ITU-T V.28 standards
The MAX232EWE-T is ideal for applications such as point-of-sale systems, industrial control, telecommunications, and any other system requiring a reliable RS-232 communication interface. Its robustness, combined with Maxim Integrated's reputation for quality, makes the MAX232EWE-T a preferred choice for designers looking to implement serial communication in their projects.
