OUTPUT VALID CONDITIONS
The DS1836 can maintain valid outputs as long as one
input remains above 1.2 volts. However, the RST out-
puts on the DS1836A (or C) use a push–pull output
structure which can maintain a valid output below 1.2
volts on an input. To sink current below 1.2 volts a resis-
tor can be connected from RST to GND (see Figure 5).
This arrangement will maintain a valid value on the RST
outputs even if all supply inputs are at 0 volts. During
conditions when the RST is in the inactive or high state
this arrangement will draw current through the pull down
resistor. A value of about 100K
should be adequate to
maintain a valid condition.
The DS1836 NMI output requires a pull–up resistor on
the output to maintain a valid output. The value of the
resistor is not critical in most cases but must be set low
enough to pull the output to a high state. A common
value used is 10K
s (see Figure 3).
