Description
Power Supply Terminal. The DS1847 will support supply
voltages ranging from +3.0V to +5.5V.
Ground Terminal.
2-Wire Serial Data Interface. The serial data pin is for serial data
transfer to and from the DS1847. The pin is open drain and may
be wire-ORed with other open drain or open collector interfaces.
2-Wire Serial Clock Input. The serial clock input is used to
clock data into the DS1847 on rising edges and clock data out on
falling edges.
Write Protect Input. If open or set to logic 1, all memory, control
are write protected. If set to a logic 0, the device is not write protected and
can be written to. The WP pin is pulled high internally.
Address Input. Pins A0, A1, and A2 are used to specify the
address of each DS1847 when used in a multi-dropped
configuration.

Address Input.
High terminal of Resistor 0. For both resistors, it is
not required that the high terminal be connected to a potential
greater than the low terminal. Voltage applied to the high terminal
of each resistor cannot exceed V
High terminal of Resistor 1.
Low terminal of Resistor 0. For both resistors, it is
not required that the low terminal be connected to a potential less
than the high terminal. Voltage applied to the low terminal of each
resistor cannot exceed V
Low terminal of Resistor 1.
