TIMAX232DR
Overview
The MAX232DR is a dual driver/receiver pair that converts TIA/EIA-232-F voltage levels to 5V TTL/CMOS levels. It features an integrated capacitive voltage generator, allowing it to operate from a single 5V supply using four external 1uF capacitors. This transceiver is a standard solution for bridging legacy serial RS232 communication with modern microcontrollers.
Why Choose This Part
The device simplifies power supply design by generating the necessary RS232 positive and negative rail voltages internally from a single 5V source. It supports data rates up to 120Kbps and provides robust +/-30V input levels, ensuring reliable communication in electrically noisy environments.
Applications
Key Specifications
Getting Started
To implement this part, connect four 1uF charge-pump capacitors as specified in the datasheet to pins 1, 3, 4, and 5. Ensure the 5V supply is decoupled with a capacitor placed close to the VCC pin, and verify that your UART logic levels are compatible with the 5V CMOS/TTL inputs.
