VALID RESET WITH V
To ensure that the CAT809 RESET pin is in a known
state when V
between RESET pin and GND is recommended. For
the CAT80, a pull-up resistor from RESET pin to V
is needed.
BI-DIRECTIOnAL RESET PIn InTERfACInG
The CAT809/80 can interface with µP/µC bi-directional
reset pins by connecting a 4.7kΩ resistor in series with
the CAT809/80 reset output and the µP/µC bi-directional
reset pin.
