To ensure that the CAT809 RESET pin is in a known state when V
between RESET pin and GND is recommended; the value is not critical. For the CAT810, a pull-up resistor from
RESET pin to V
The CAT809/810 can interface with P/ C bi-directional reset pins by connecting a 4.7 k resistor in series with the
CAT809/810 reset output and the P/ C bi-directional reset pin.
