MAX3221ECAE+

Description

Product Details

The MAX3221E/MAX3223E/MAX3243E are 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/MAX3223E/MAX3243E achieve a 1µA supply current with Maxim’s revolutionary AutoShutdown™ feature. They save power without changes to the existing BIOS or operating system by enter ing 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 trans mitter output stage, delivering true RS-232 performance from a +3.0V to +5.5V supply with a dual charge pump. The charge pump requires only four small 0.1µF capaci tors for operation from a +3.3V supply. Each device is guaranteed to run at data rates of 250kbps while main taining RS-232 output levels
