Hot-selling and scarce MAX3243ECAI 250kbps RS-232 Transceivers with AutoShutdown SSOP28 spot stock

Product Descriptions

The MAX3221E/MAX3223E/MAX3243E are 3V-poweredEIA/TIA-232 and V .28/V .24 communications interfaceswith automatic shutdown/wakeup features, high datarate capabilities, and enhanced electrostatic discharge(ESD) protection . All transmitter outputs and receiverinputs are protected to ±15kV using IEC 1000-4-2 AirGap Discharge, to ±8kV using IEC 1000-4-2 ContactDischarge, and to ±15kV using the Human Body Model .

The  MAX3221E/MAX3223E/MAX3243E  achieve  a1µA   supply   current  with   feature . They save power withoutchanges to the existing BIOS or operating system by entering low-power shutdown mode when the RS-232 cable isdisconnected, or when the transmitters of the connectedperipherals are off .

The transceivers have a proprietary low-dropout transmitter output stage, delivering true RS-232 performancefrom a +3 .0V to +5 .5V supply with a dual charge pump .The charge pump requires only four small 0.1µF capacitors for operation from a +3 .3V supply . Each device isguaranteed to run at data rates of 250kbps while maintaining RS-232 output levels .

The MAX3221E contains just one driver and one receiver,making it the smallest single-supply RS-232 transceiver .The MAX3223E has two drivers and two receivers . TheMAX3243E is a complete 3-driver/5-receiver serial portideal for notebook or subnotebook computers . It alsoincludes two noninverting receiver outputs that are alwaysactive, allowing external devices to be monitored withoutforward biasing the protection diodes in circuitry that maybe powered down .
