Description

This is RS-232 Transceivers. MAX3221E, AVAILABLE MAX3223E, MAX3243E ±15kV ESD-Protected, 1 A, 3.0V to 5.5V, 250kbps, RS-232 Transceivers with AutoShutdown General Description Next Generation Device Features The MAX3221E, MAX3223E, MAX3243E are 3V-powered EIA, TIA-232 and V.28, V.24 communications interfaces with automatic shutdown, wakeup features, high datarate 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. The MAX3221E, MAX3223E, MAX3243E achieve a 1 A 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 transceivers have a proprietary low-dropout transmitter output stage.
