DS2740
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
μ
s and then release it to allow the
DS2740 to present valid data. The bus master can then sample the data t
from the start of the read-
RDV
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
μ
s minimum
SLOT
recovery time, t
, between cycles. See Figure 12 for more information.
