MAX3227ECAE+

MAX3227ECAE+ is a 3V-powered EIA/TIA-232 and V.28/V.24 communications interface 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. It achieves a 1μA supply current using Maxim’s revolutionary AutoShutdown Plus™ feature. This device automatically enters 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. It turns 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.

• 1 driver/1 receiver
• Guarantees 1Mbps for high-speed applications such as communicating with ISDN modems
• Charge pump requires only four small 0.1μF capacitors for operation from a 3.3V supply
• Logic-level o/p (READY) asserts when charge pump is regulating & device is ready to begin transmit
• Operating temperature range from 0°C to +70°C
• Available in 16 pin SSOP package
