CAT809, CAT810
VALID RESET WITH V
To ensure that the CAT809 RESET pin is in a known
state when V
resistor between RESET pin and GND is recommended;
the value is not critical. For the CAT810, a pull-up
resistor from RESET pin to V
BI-DIRECTIONAL RESET PIN INTERFACING
The CAT809/810 can interface with µP/µC bi-directional
reset pins by connecting a 4.7 kΩ resistor in series with
the CAT809/810 reset output and the µP/µC bi-directional
reset pin.
