VALID TO 0 VOLTS VCC Figure 9
OUTPUT VALID CONDITIONS
The RST output uses a push-pull output which can maintain a valid output down to 1.0 volts VCC. To sink
current below 1.0 volts a resistor can be connected form RST to Ground (see Figure 9.) This arrangement
will maintain a valid value on RST during both power-up and -down but will draw current when RST is
in the high state. A value of about 100 k
=should be adequate in most situations. The output with a
resistor pull-down can maintain a valid reset down to VCC equal to 0V.
