Introduction

AI Translation

The MAX3221/MAX3223/MAX3243 achieve 1µA supply current with Maxim’s revolutionary AutoShutdown™ feature. When the MAX3221/MAX3223/MAX3243 do not sense a valid signal level on their 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 MAX3221/MAX3223/MAX3243 require 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. The MAX3221 is a 1 - driver/1 - receiver 16 - pin SSOP version of the 20 - pin 2 - driver/2 - receiver MAX3223. The MAX3243 is a 3 - driver/5 - receiver with a complementary always - active receiver for external monitoring in a variety of 28 pin packages.
