MAX999EUK+T from Analog Devices Inc Maxim Integrated, 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 | Q | output | Comparator TTL/CMOS-compatible output, guaranteed to pull within 0.52V of either GND or VCC without external pullup or pulldown. |
| 2 | GND | power_in | Ground pin; the supply and all input and output limits are referenced to GND, and VCC to GND must not exceed 5.5V. |
| 3 | IN+ | input | Noninverting comparator input, with a common-mode range extending 100mV beyond both supply rails (-0.1V to VCC + 0.1V) and input current limited to ±20mA. |
| 4 | IN- | input | Inverting comparator input, with a common-mode range extending 100mV beyond both supply rails (-0.1V to VCC + 0.1V) and input current limited to ±20mA. |
| 5 | VCC | power_in | Positive supply input, specified from 2.7V to 5.5V; VCC to GND must be ≤5.5V. |
