ANALOG DEVICES MAX3223EEUP+ Transceiver RS232, 3V-5.5V supply, 2 Drivers, TSSOP-20

MAX3223EEUP+ is a RS-232 transceiver with AutoShutdown. It is a 3V-powered EIA/TIA-232 and V.28/V.24 communications interface 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 AirGap discharge, to ±8kV using IEC 1000-4-2 contact discharge, and to ±15kV using the human body model. It saves 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 has a proprietary low-dropout transmitter output stage, delivering true RS-232 performance from a +3.0V to +5.5V supply with a dual charge pump. Applications include notebook, subnotebook, and palmtop computers, cellular phones, battery-powered equipment, handheld equipment, peripherals, printers.
