Présentation
Description
Key features:
- Dual-channel (2 drivers, 2 receivers).
- Onboard charge pump eliminates the need for external ±12V power.
- Operates at 5V supply, up to 120kbps data rate.
- ESD protection (±15kV, human-body model).
- Industrial temperature range (−40°C to +85°C).
Packaged in a 16-pin SOIC (EESE), it’s widely used in serial communication interfaces. Common applications include UART-to-RS-232 adapters, industrial controls, and embedded systems.
Alternatives: MAX3232 (3V–5.5V operation).
Concise, robust, and reliable for legacy serial communication.
Equivalent
- ST232E (STMicroelectronics)
- SP232E (Sipex/Exar)
- ADM232A (Analog Devices)
- ICL232 (Intersil/Renesas)
- HIN232 (Holt Integrated Circuits)
These are pin-compatible RS-232 transceivers with similar specs (dual drivers/receivers, 5V operation). Always verify datasheet compatibility for your application.
Features
- Dual Charge Pump: Generates ±5V from a single +5V supply, eliminating the need for external power supplies.
- Compliance: Meets EIA/TIA-232 and V.28/V.24 standards.
- Data Rate: Supports up to 120kbps transmission speed.
- Low Power: Typically consumes 5mA supply current.
- ESD Protection: ±15kV (Human Body Model) on I/O lines.
- Package: 16-pin SOIC (EESE), suitable for surface-mount applications.
- Operating Temp: -40°C to +85°C, ideal for industrial use.
- Pin Compatibility: Drop-in replacement for older MAX232 variants.
Ideal for RS-232 communication in embedded systems, industrial controls, and legacy serial interfaces.
Pinout
### Key Functions:
- Converts TTL/CMOS logic levels (0V/5V) to RS-232 levels (±3V to ±15V) and vice versa.
- Includes 2 drivers (TX) and 2 receivers (RX).
- Operates from a single +5V supply.
- Features on-board charge-pump voltage converters (no external ±12V required).
### Pin Count:
- 16-pin (SOIC package, EESE suffix).
Commonly used in UART communication between microcontrollers and RS-232 devices (e.g., PCs).
Manufacturer
Maxim Integrated was a leading semiconductor company specializing in analog and mixed-signal ICs, known for high-performance power management, data conversion, and interface solutions. Its products were widely used in industrial, automotive, and consumer electronics.
Analog Devices (ADI) is a global leader in analog, mixed-signal, and DSP technologies, serving diverse markets like healthcare, communications, and automotive. The merger strengthened ADI's portfolio with Maxim's expertise in power and signal conditioning.
The MAX232EESE+T is a classic RS-232 transceiver, converting TTL/CMOS logic levels to RS-232 voltages, commonly used in serial communication.
