READ-TIME SLOTS
A read-time slot is initiated when the bus master pulls the 1-Wire bus line from a logic-high level to a
logic-low level. The bus master must keep the bus line low for at least 1 s and then release it to allow the
DS2740 to present valid data. The bus master can then sample the data t
RDV
from the start of the read-
time slot. By the end of the read-time slot, the DS2740 releases the bus line and allows it to be pulled
high by the external pullup resistor. All read-time slots must be t

in duration with a 1 s minimum
recovery time, t
