AVAILABLE MAX3224E/MAX3225E/ MAX3226E/MAX3227E/ MAX3244E/MAX3245E ±15kV ESD-Protected, 1µA, 1Mbps, 3.0V to 5.5V, RS-232 Transceivers with AutoShutdown Plus ________________General Description 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 highspeed 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 (READYF) uthnatcatsisoenrtsawl hDeinatgherachmarsge 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. ________________________Applications Notebook, Subnotebook, and Palmtop Computers Cellular Phones Battery-Powered Equipment Hand-Held Equipment Peripherals Printers __Next Generation Device Features ♦ For Space-Constrained Applications: MAX3228E/MAX3229E: ±15kV ESD-Protected, +2.5V to +5.5V, RS-232 Transceivers in UCSP™ MAX3222E/MAX3232E/MAX3241E/MAX3246E: ±15kV ESD-Protected, Down to 10nA, +3.0V to +5.5V, Up to 1Mbps, True RS-232 Transceivers (MAX3246E Available in UCSP) ♦ For Low-Voltage or Data Cable Applications: MAX3380E/MAX3381E: +2.35V to +5.5V, 1µA, 2Tx/2Rx RS-232 Transceivers with ±15kV ESD-Protected I/O and Logic Pins Ordering Information PART TEMP RANGE PIN-PACKAGE MAX3224ECTP+ 0°C to +70°C 20 TQFN-EP* MAX3224ECUP+ 0°C to +70°C 20 TSSOP MAX3224ECAP+ 0°C to +70°C 20 SSOP MAX3224ECPP+ 0°C to +70°C 20 Plastic DIP MAX3224EETP+ -40°C to +85°C 20 TQFN-EP* MAX3224EEUP+ -40°C to +85°C 20 TSSOP MAX3224EEAP+ -40°C to +85°C 20 SSOP MAX3224EEPP+ -40°C to +85°C 20 Plastic DIP MAX3224EAAP+ -40°C to +125°C 20 SSOP +Denotes a lead(Pb)-free/RoHS-compliant package. *EP .
