DS1834/A/D
OUTPUT VALID CONDITIONS
All versions of the DS1834 can maintain valid outputs as long as one input remains above 1.2 volts.
However, the RST outputs on the DS1834 use a push-pull output structure which can maintain a valid
output below 1.2 volts. To sink current below 1.2 volts a resistor can be connected from RST to GND
(see Figure 5). This arrangement will maintain a valid value on the RST outputs even if all inputs are at 0
volts. During both power-up and power-down this arrangement will draw current when RST is in the high
state. A value of about 100 k ? = should be adequate to maintain a valid condition.
The DS1834A requires pull-up resistors on the outputs to maintain a valid output. The value of the
resistors 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 10 k ? s (see Figure 6 and Figure 7).

Note: If outputs are pulled-up to different voltages the outputs can not be connected to form a wired
"AND".
