MAX232EIDR

The MAX232EIDR is a dual driver/receiver IC from Maxim Integrated (now part of Analog Devices), designed for RS-232 communication in TTL/CMOS systems. It features two drivers and two receivers, converting TTL/CMOS logic levels (±5V) to RS-232 voltage levels (±7.5V) and vice versa, enabling communication with serial ports.
Key features:
- 3V to 5.5V supply range, suitable for low-power applications.
- Onboard charge-pump voltage converters, eliminating the need for external ±12V supplies.
- 120kbps data rate, sufficient for standard serial communication.
- ESD protection on RS-232 lines (up to ±15kV).
Applications include industrial control, embedded systems, and legacy serial interfaces. The EIDR suffix denotes a SOIC-16 package.
A compact, reliable solution for TTL-to-RS-232 level shifting.
