MAX3232EIDBR

The MAX3232EIDBR is a 3.3V-powered RS-232 transceiver from Texas Instruments, designed for serial communication between microcontrollers and RS-232 devices. It features two drivers and two receivers, supporting data rates up to 250kbps.
Key highlights:
- Low power consumption with a 1µA shutdown mode.
- ±15kV ESD protection on I/O lines for robustness.
- Operates from 3V to 5.5V, making it compatible with mixed-voltage systems.
- Auto-powerdown to conserve energy when idle.
Packaged in a SSOP-16 form factor, it’s ideal for embedded systems, industrial controls, and battery-powered devices. The MAX3232EIDBR ensures reliable TTL-to-RS-232 level conversion, maintaining signal integrity over longer cables.
A cost-effective, industry-standard solution for UART-to-RS-232 interfacing.
