MAX3223EAP+

MAX3223EAP+ is a +3V to +5.5V, RS232 transceiver with autoshutdown. It achieves 1µA supply current with Maxim’s revolutionary AutoShutdown™ feature. When the MAX3243 do not sense a valid signal level on its receiver inputs, the onboard power supply and drivers shut down. This occurs if the RS-232 cable is disconnected or if the transmitters of the connected peripheral are turned off. The system turns on again when a valid level is applied to any RS-232 receiver input. The MAX3223 requires only 0.1µF capacitors in 3.3V operation, and can operate from input voltages ranging from +3.0V to +5.5V. A proprietary, high-efficiency, dual charge-pump power supply and a low-dropout transmitter combine to deliver true RS-232 performance from a single +3.0V to +5.5V supply.

• 2-driver/2-receiver
• Integrated charge pump circuitry simplifies power requirement
• Eliminates the need for a ±12V supply
• AutoShutdown feature is enabled after no activity on receiver inputs for 30µs
• Software control option for shutdown
• Temperature range from -40°C to +85°C
• Available in 20 pin SSOP package
