General Description
The TCN75 is a serially programmable temperature
sensor that notifies the host controller when ambient
temperature exceeds a user programmed set point.
Hysteresis is also programmable. The INT/CMPTR
output is programmable as either a simple comparator
for thermostat operation or as a temperature event
interrupt.
Communication
accomplished via a two-wire bus that is compatible with
industry standard protocols. This permits reading the
current temperature, programming the set point and
hysteresis, and configuring the device.

2-wire bus to activate the low power Standby mode.
Address selection inputs allow up to eight TCN75s to
