• an enhanced automatic powerdown function that powers down the on-chip power-supply and driver circuits. Automatic powerdown occurs when all receiver and transmitter inputs detect no signal transitions for a period of 30s. The ICL3238E automatically powers back up whenever it senses a transition on any transmitter or receiver input. The transmitter and logic inputs include active feedback resistors that retain the input state when driven to a valid logic level. Table 1 summarizes the features of.
