Description
The MAX3221EAE+T is a single-channel RS-232 transceiver designed by Maxim Integrated, now part of Analog Devices. It operates with a single +3V to +5.5V power supply and meets the RS-232 and V.28/V.24 communication standards. The device is ideal for battery-powered and portable applications due to its low power consumption, featuring a 1µA shutdown mode to conserve energy. It integrates a charge pump that requires no external capacitors, simplifying the design.
The transceiver operates at data rates up to 250kbps, ensuring compatibility with high-speed serial communication. It features an automatic shutdown that engages when the device is inactive, further enhancing power efficiency. The MAX3221EAE+T also includes enhanced electrostatic discharge (ESD) protection on the RS-232 lines, safeguarding against voltage spikes.
Packaged in a 16-pin TSSOP, it is suitable for space-constrained applications. Typical use cases include handheld devices, laptops, and peripherals where RS-232 connectivity is needed. The "E" denotes the extended temperature range, while the "+T" indicates a lead-free, tape-and-reel packaging for automated assembly.
