Hot-selling and scarce MAX3225ECAP+ 3.0V to 5.5V, RS-232 Transceivers with AutoShutdown Plus SSOP20 spot stock

Product Descriptions

The MAX3224E/MAX3225E/MAX3226E/MAX3227E/  MAX3244E/MAX3245E 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, ±8kV using  IEC 1000-4-2 Contact Discharge, and ±15kV using the  Human Body Model.

All devices achieve a 1μA supply current using Maxim’s  revolutionary AutoShutdown Plus™ feature. These devices automatically enter 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. They turn on again when they sense a valid  transition at any transmitter or receiver input.  AutoShutdown Plus saves power without changes to the  existing BIOS or operating system.

The MAX3225E/MAX3227E/MAX3245E also feature MegaBaud™ operation, guaranteeing 1Mbps for  high-speed applications such as communicating with  ISDN modems. The MAX3224E/MAX3226E/MAX3244E  guarantee 250kbps operation. The transceivers have a  proprietary low-dropout transmitter output stage enabling  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 capacitors for operation from a 3.3V  supply. The MAX3224E–MAX3227E feature a logic-level  output (READY) that asserts when the charge pump is  regulating and the device is ready to begin transmitting.

All devices are available in a space-saving TQFN,  SSOP, and TSSOP (MAX3224E/MAX3225E/MAX3244E/ MAX3245E) packages.
