VALID RESET WITH VCC UNDER 1.0V
To ensure that the CAT811 RESET
pin is in a known
state when VCC is under 1.0V, a 100k pull-down
resistor
between
RESET
pin
and
GND
is
recommended; the value is not critical. For the
CAT812, a pull-up resistor from RESET pin to VCC is
needed.

Valid with VCC under 1.0V

BI-DIRECTIONAL RESET PIN INTERFACING
The CAT811/812 can interface with P/C bi-
directional reset pins by connecting a 4.7k resistor in
series with the CAT811/812 reset output and the
P/C bi-directional reset pin.
