OUTPUT VALID CONDITIONS
The
output uses a push-pull output which can maintain a valid output down to 1.0V V
. To sink

current below 1.0V a resistor can be connected form
to Ground (see Figure 9.) This arrangement

will maintain a valid value on
during both power-up and -down but will draw current when

RST
in the high state. A value of about 100kW should be adequate in most situations. The output with a
resistor pull-down can maintain a valid reset down to V
equal to 0V.
