TCN75AVOA713

Microchip Tech · Temperature Sensors · SOIC-8

TCN75AVOA713 from Microchip Tech, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	SDA	bidirectional	Bidirectional serial data pin for the I2C-compatible interface, which requires a pull-up resistor to output data.
2	SCL	input	Serial clock input pin; all bus communication and timing is relative to the clock generated by the host controller.
3	ALERT	output	Open-drain temperature alert output that signals when the ambient temperature goes beyond the user-programmed limit.
4	GND	power_in	System ground pin.
5	A2	input	Device address select pin (bit 2, LSb side of the 7-bit address), set externally to VDD for '1' or GND for '0'.
6	A1	input	Device address select pin (bit 1), set externally to VDD for '1' or GND for '0'.
7	A0	input	Device address select pin (bit 0), set externally to VDD for '1' or GND for '0'.
8	VDD	power_in	Power supply input; the operating voltage in the DC electrical specification table (2.7V to 5.5V per the features list) is applied on this pin.
