VALID RESET WITH VCC unDER 1.0V
To ensure that the CAT809 RESET pin is in a known
state when VCCisunder1.0V,a>10kpull-downresistor
between RESET pin and GND is recommended. For
the CAT80, a pull-up resistor from RESET pin to VCC
is needed.

The CAT809/80 can interface with P/C bi-directional
reset pins by connecting a 4.7k resistor in series with
theCAT809/80resetoutputandtheP/Cbi-directional
reset pin.
