# TS881ILT

**STMicroelectronics** · Comparators · SOT-23-5

TS881ILT from STMicroelectronics, in a SOT-23-5. 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 | OUT | output | Push-pull rail-to-rail comparator output, with VOH of 4.86 V min at 2 mA source and VOL of 95 mV typ. at 2 mA sink at VCC = 5 V. |
| 2 | VCC- | power_in | Negative supply (ground) pin, the reference for all voltages, which must stay within VCC- - 0.3 V to VCC+ + 0.3 V. |
| 3 | IN+ | input | Non-inverting rail-to-rail comparator input, with an input voltage range of (VCC-) - 0.3 V to (VCC+) + 0.3 V. |
| 4 | IN- | input | Inverting rail-to-rail comparator input, with an input voltage range of (VCC-) - 0.3 V to (VCC+) + 0.3 V. |
| 5 | VCC+ | power_in | Positive supply pin, operating from 0.85 V to 5.5 V (0.85 V to 5.5 V up to 85 °C, 1.1 V to 5.5 V up to 125 °C) and 6 V absolute maximum. |

## CAD (KiCad official)

- Symbol: `TS881ILT`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `ts881ilt-etched.step` / `ts881ilt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ts881ilt.step` / `ts881ilt.glb` are the bare package body.
