... Most devices in the ICL32XX family provide pins that allow the user to force the IC into the low power, standby state. On the ICL3222 and ICL3241, the powerdown control is via a simple shutdown (SHDN) pin. Driving this pin high enables normal operation, while driving it low forces the IC into it’s powerdown state. Connect SHDN to V function isn’ ...

... NOTE: 4. Applies only to the ICL3241 and ICL3243. 3-12 ICL3221 thru ICL3243 are floating (but pulled to GND by the internal receiver pull down resistors), the INVALID logic detects the invalid levels and drives the output low. The power management logic then uses this indicator to power down the interface block. ...
