VALID RESET WITH V

unDER 1.0V
To ensure that the CAT809
RESET
pin is in a known
state when V
CC
is under 1.0V, a >10k pull-down resistor
between
RESET
pin and GND is recommended. For
the CAT810, a pull-up resistor from RESET pin to V
CC
is needed.

The CAT809/80 can interface with μP/μC bi-directional
reset pins by connecting a 4.7k resistor in series with
the CAT809/80 reset output and the μP/μC bi-directional
reset pin.
