max3221

The MAX3221 is a single-channel RS-232 driver/receiver designed for high-speed communication. It operates from a single 3.0V to 5.5V supply, making it ideal for portable devices and battery-powered applications. The device includes a charge-pump voltage converter to generate RS-232 voltage levels, eliminating the need for external power supplies. The MAX3221 features a 1μA low-power shutdown mode, ensuring minimal power consumption when in standby. The receiver has a typical input sensitivity of ±30mV, allowing for reliable data reception even in noisy environments. With a data rate of 250kbps, it is suitable for high-speed communication in industrial and consumer applications. The device comes in a compact SSOP package, making it easy to integrate into space-constrained designs. With its low-power operation, high-speed communication, and compact form factor, the MAX3221 is an excellent choice for designers looking to add RS-232 connectivity to their portable and space-constrained applications.
