3.0
The descriptions of the pins are listed in
TABLE 3-1:
3.1
These pins are device address input pins.
The address pins correspond to the Least Significant
bits (LSb) of address bits. The Most Significant bits
(MSb) (A6, A5, A4, A3). This is shown in
TABLE 3-2:
3.2
The GND pin is the system ground pin.
3.3
SDA is a bidirectional input/output pin, used to serially
transmit data to/from the host controller. This pin
requires a pull-up resistor. (See Section 4.0 “Serial
Communication”).

Pin Function
3.4
The SCLK is a clock input pin. All communication and
timing is relative to the signal on this pin. The clock is
generated by the host or master controller on the bus.
(See Section 4.0 “Serial Communication”).
3.5
The MCP98242 Event pin is an open-drain output. The
device outputs a signal when the ambient temperature
goes beyond the user-programmed temperature limit.
(see Section 5.2.3 “Event Output Configuration”).
3.6
V
specified in the DC electrical specification table, is
applied on this pin.
3.7
There is an internal electrical connection between the
Exposed Thermal Pad (EP) and the GND pin; they
must be connected to the same potential on the Printed
Circuit Board (PCB).
DD
