MAX232 Serial Programming Driver/Receiver IC SMD Package

MAX232 Serial Programming Driver/Receiver IC SMD Package 

The MAX232 is a widely used serial programming driver/receiver IC that enables reliable communication between TTL/CMOS logic levels and RS-232 serial interfaces. It integrates two RS-232 line drivers and two line receivers, allowing full-duplex serial communication with PCs, programmers, and other RS-232 compatible devices.

The IC uses an internal charge-pump voltage converter to generate the required RS-232 voltage levels from a single 5 V supply, eliminating the need for dual power supplies. Packaged in a surface-mount (SMD) package, the MAX232 is ideal for compact PCB designs and embedded programming interfaces.
