Included on the chip is a shutdown pin for reducing supply current to near zero. During shutdown one receiver remains active to detect incoming RS232 signals, for example, to wake up a system. All other receivers and the drivers assume high impedance states during shutdown. The driver disable function provides additional control of operating mode. When driver disable is high the charge pump and drivers turn off.
