3.0
The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
3.1
SDA is a bidirectional input/output pin, used to serially
transmit data to and from the host controller. This pin
requires a pull-up resistor to output data.
3.2
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 controller on the bus.
3.3
V
specified in the DC electrical specification table, is
applied on this pin.
3.4
GND is the system ground pin.

The TCN75A’s ALERT pin is an open-drain output. The
device outputs an alert signal when the ambient
temperature goes beyond the user-programmed
temperature limit.
3.6
A2, A1 and A0 are device or slave address input pins.
The address pins are the Least Significant bits (LSb) of
the device address bits. The Most Significant bits
(MSb) (A6, A5, A4, A3) are factory-set to <1001>. This
is illustrated in Table 3-2.
