VALID RESET WITH V
CC
UNDER 1.0 V
To ensure that the CAT809
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 CAT810, a pull-up resistor from
RESET pin to V
CC
is needed.
BI-DIRECTIONAL RESET PIN INTERFACING
The CAT809/810 can interface with
μ
P/
μ
C bi-directional reset pins by connecting a 4.7 k
resistor in series with the
CAT809/810 reset output and the
μ
P/
μ
C bi-directional reset pin.
