Microchip Tech · Temperature Sensors · MSOP-8
MCP9808T-E from Microchip Tech, in a MSOP-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 line of the 2-wire SMBus/I2C interface that requires an external pull-up resistor, with SDA output VOL limited to 0.4 V max at IOL = 3 mA. |
| 2 | SCL | input | Serial clock input from the bus master, to which all communication and timing is referenced, with VIH min of 0.7 VDD and VIL max of 0.3 VDD. |
| 3 | Alert | output | Open-drain temperature alert output that signals when ambient temperature exceeds user-programmed limits and requires an external pull-up resistor, with VOL max of 0.4 V at IOL = 3 mA. |
| 4 | GND | power_in | System ground pin. |
| 5 | A2 | input | Device address input whose level (connected to VDD or GND) sets address bit A2 of the 7-bit slave address and must match the device pin configuration. |
| 6 | A1 | input | Device address input whose level (connected to VDD or GND) sets address bit A1 of the 7-bit slave address and must match the device pin configuration. |
| 7 | A0 | input | Device address input whose level (connected to VDD or GND) sets address bit A0 of the 7-bit slave address and must match the device pin configuration. |
| 8 | VDD | power_in | Supply pin; the operating voltage range is 2.7 V to 5.5 V per the DC electrical specifications. |
