MAX3221EEAE+ Datasheet PDF - Maxim Integrated

●The MAX3221EEAE+ is a RS-232 Transceiver for handheld equipment. The MAX3221E is 3V-powered EIA/TIA-232 and V.28/V.24 communications interfaces with automatic shutdown/wakeup features, high data rate capabilities and enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 air-gap discharge, to ±8kV using IEC 1000-4-2 contact discharge and to ±15kV using the human body model. The MAX3221E achieve a 1µA supply current with Maxim"s revolutionary AutoShutdown™ feature. They save power without changes to the existing BIOS or operating system by entering low-power shutdown mode when the RS-232 cable is disconnected or when the transmitters of the connected peripherals are off. The transceiver have a proprietary low-dropout transmitter output stage, delivering true RS-232 performance from a +3.0 to +5.5V supply with a dual charge pump.

●ESD sensitive device, take proper precaution while handling the device.
