# LM86CIMX

**Texas Instruments** · Temperature Sensors · SOIC-8

LM86CIMX from Texas Instruments, 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 | VDD | power_in | Positive supply voltage input, specified for a DC voltage from 3.0 V to 3.6 V (absolute maximum supply is -0.3 V to 6.0 V). |
| 2 | D+ | passive | Diode current source output to the diode anode of a remote diode-connected transistor; it must not be forward biased by more than 50 mV or temperature measurements may be corrupted. |
| 3 | D- | passive | Diode return current sink to the diode cathode; the D- input current is limited to ±1 mA absolute maximum. |
| 4 | T_CRIT_A | output | Active-low open-drain T_CRIT alarm output that needs a pull-up resistor, used for controller interrupt or power supply shutdown; voltage limit 6.0 V, output sink current limit 10 mA, saturation voltage 0.4 V max at 6.0 mA. |
| 5 | GND | power_in | Power supply ground pin. |
| 6 | ALERT | output | Active-low open-drain interrupt output that needs a pull-up resistor, asserted when temperature leaves the programmed HIGH/LOW window or exceeds T_CRIT; voltage limit 6.0 V, output sink current limit 10 mA. |
| 7 | SMBData | bidirectional | Open-drain SMBus bidirectional data line to and from the controller, requiring a pull-up resistor; voltage limit -0.5 V to 6.0 V and sink current limit 10 mA. |
| 8 | SMBCLK | input | SMBus clock input from the controller, requiring a pull-up resistor; voltage limit -0.5 V to 6.0 V. |

## CAD (KiCad official)

- Symbol: `LM86CIMX`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `lm86cimx-etched.step` / `lm86cimx-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm86cimx.step` / `lm86cimx.glb` are the bare package body.
