Overview
Description
The MAX3232CDBR is a 3.0V to 5.5V-powered RS-232 transceiver from Texas Instruments, designed for serial communication in industrial, embedded, and consumer applications. It features two drivers and two receivers, supporting full-duplex communication at up to 250kbps.
Key highlights:
- Low power consumption with a 1µA shutdown mode.
- ±15kV ESD protection on I/O lines for robustness.
- Auto-powerdown to conserve energy when idle.
- SOIC-16 package, suitable for space-constrained designs.
The MAX3232CDBR converts TTL/CMOS logic levels to RS-232 voltage levels, ensuring compatibility with legacy serial interfaces (e.g., UART). It’s ideal for microcontrollers, PCs, and peripherals requiring reliable, noise-resistant communication.
For detailed specs, refer to the datasheet.
