FUNCTION
+5V External Power Supply. Decouple with a 0.1µF capacitor to ground.
Negative Terminal of the Voltage Inverter Charge-Pump Capacitor
Shutdown Active-Low (0 = off, 1 = on)
Valid Signal Detector Output, Active-Low. A logic high indicates that a valid
RS-232 level is present on the receiver input.
