MAX3227EEAE+

MAX3227EEAE+ is a ±15kV ESD-protected, RS-232 transceiver with AutoShutdown plus. 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 air-gap discharge, ±8kV using IEC 1000-4-2 contact discharge, and ±15kV using the human body model. It achieves a 1μA supply current using the revolutionary AutoShutdown Plus™ feature. This device automatically enters a low-power shutdown mode when the RS-232 cable is disconnected or the transmitters of the connected peripherals are inactive, and the UART driving the transmitter inputs is inactive for more than 30 seconds. Applications include notebooks, subnotebooks, and palmtop computers, cellular phones, battery-powered equipment, hand-held equipment, peripherals, and printers.
