+    :keywords: TC74
+
+The TC74 sensor platform allows you to use your TC74 (`datasheet
+<https://ww1.microchip.com/downloads/en/DeviceDoc/21462D.pdf>`__, `Adafruit
+<https://www.adafruit.com/product/4375>`__) temperature sensors with ESPHome.
+The :ref:`I²C Bus <i2c>` is required to be set up in your configuration for this
+sensor to work.

+
+    # Example configuration entry
+    sensor:
+      - platform: tc74
+        name: "Living Room Temperature"
+
+Configuration variables:
+------------------------
+
+- **update_interval** (*Optional*, :ref:`config-time`): The interval to check
+  the sensor. Defaults to ``60s``.
+- **address** (*Optional*, int): The I²C address of the sensor. Defaults to
+  ``0x48``, the address of the TC74A0. For suffixes other than ``A0`` add the
+  final digit to ``0x48`` to calculate the address. For example, the TC74A5 has
+  I²C address ``0x4D``.
+- All other options from :ref:`Sensor <config-sensor>`.
