MAX3224E, MAX3225E, MAX3226E, MAX3227E, MAX3244E, MAX3245E ±15kV ESD-Protected, 1µA, 1Mbps, 3.0V To 5.5V, RS-232 Transceivers With AutoShutdown Plus

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 1A 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 77d 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 0.1F 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.
