VALID RESET WITH V
CC
UNDER 1.0 V
To ensure that the CAT811
RESET
pin is in a known
state when V
CC
is under 1.0 V, a 100 k
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 V
CC
is needed.

BI-DIRECTIONAL RESET PIN INTERFACING
The CAT811/812 can interface with

reset pins by connecting a 4.7 k
resistor in series with
the CAT811/812 reset output and the
