Note 2: All devices are 100% production tested at T
Note 3: V
Note 4: Use external current-limit resistor to limit current to 20mA (max).
Note 5: CEIN/CEOUT resistance is tested with V
Note 6: WDI is internally serviced within the watchdog period if WDI is left unconnected.
Note 7: The WDI input current is specified as the average input current when the WDI input is driven high or low. The WDI input is
