The MAX16816 can only transmit data to the master
when the master issues read time slots.
All read time slots must be a minimum of 60µs in dura-
tion with a minimum of a 1µs recovery time between
slots. A read time slot is initiated by the master device
pulling the 1-Wire bus low for a minimum of 1µs and
then releasing it (Figure 9). After the master initiates the
read time slot, the MAX16816 will transmit a ‘1’ or a ‘0’

on the bus. The MAX16816 transmits a ‘1’ by leaving
the bus high and transmits a ‘0’ by pulling the bus low.
When transmitting a ‘0’, the MAX16816 will release the
bus before the end of the time slot, and the bus will be
pulled back to its high idle state by the pullup resistor.
Output data from the MAX16816 is valid for 15µs after the
falling edge that initiated the read time slot. Therefore, the
master must release the bus and then sample the bus
state within 15µs from the start of the slot.
