TIMAX3232CPWR
Overview
The MAX3232CPWR is a dual-channel RS-232 line driver and receiver designed for high-speed serial communication at data rates up to 250kbps. It features a proprietary low-dropout transmitter output stage and a dual charge pump, allowing true RS-232 performance from a single 3V to 5.5V supply. This component is widely used for bridging standard UART logic to industrial-level serial interfaces while maintaining low power consumption.
Why Choose This Part
The device simplifies power supply design by requiring only four small 0.1uF external capacitors to generate the necessary RS-232 voltage levels. It offers high reliability with 15kV HBM ESD protection and features 300mV of receiver hysteresis to ensure robust performance in noisy environments.
Applications
Key Specifications
Getting Started
To implement this part, place 0.1uF charge-pump capacitors close to the pins as specified in the datasheet to ensure stable voltage doubling and inversion. For prototyping, the 16-TSSOP package can be used with standard TSSOP-to-DIP adapter boards or integrated directly into PCB layouts using 0.65mm pitch footprints. Ensure that the logic-side VCC matches your microcontroller's I/O voltage, as the device supports a wide 3V to 5.5V range.
