概述
Description
The MAX3243CDBR is a 3V to 5.5V-powered, 3-driver/5-receiver RS-232 transceiver from Texas Instruments. It features AutoShutdown Plus™, reducing power consumption by entering low-power mode when inactive.
Key specs:
- Data rates up to 250kbps
- ±15kV ESD protection (HBM) on I/O lines
- 1µA shutdown current (typical)
- Small SSOP-16 package
Applications include portable devices, industrial systems, and legacy serial interfaces. It integrates charge-pump voltage converters, eliminating the need for external ±12V supplies.
The MAX3243CDBR is pin-compatible with older RS-232 transceivers, making it a drop-in upgrade for power-sensitive designs.
