Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | N.C. | unconnected | No connection. Not internally connected - may be left floating. |+| 2 | IN- | input | Comparator inverting input. Common-mode range extends from -0.2V to (VCC - 1.2V). Input bias current typically 75nA; input capacitance ~3pF. Either input may be driven to the absolute-max limit without false output inversion provided the other input is within the common-mode range. |+| 3 | IN+ | input | Comparator noninverting input. Common-mode range -0.2V to (VCC - 1.2V). Input bias current typically 75nA; input capacitance ~3pF. Internal hysteresis (typ 1.5mV input-referred) ensures clean switching with slow-moving signals. |+| 4 | GND | power_in | Ground / negative supply return. Connect to the low-inductance ground plane; place the 0.1µF VCC decoupling cap between VCC and GND as close to the pins as possible. |+| 5 | N.C. | unconnected | No connection. Not internally connected - may be left floating. |+| 6 | OUT | output | Comparator push-pull output. Rail-to-rail operation without external pullup; VOH within 0.4V of VCC and VOL within 0.4V of GND at ±2mA. Short-circuit current typ 90mA sourcing / 74mA sinking at VCC=5.5V; tolerant of continuous short to either rail. Placed in a high-impedance state when SHDN is driven low. |+| 7 | VCC | power_in | Positive supply, +2.7V to +5.5V (absolute max +6V). Supply current per comparator typ 225µA at 2.7V, 300µA (max 650µA) at 5.5V; drops to ~1nA in shutdown. Bypass with a 0.1µF ceramic capacitor to GND close to the pin. |+| 8 | SHDN | input | Active-low shutdown input (overlined SHDN). Drive low to enter shutdown (output Hi-Z, ICC ≈ 1nA); drive high or tie to VCC for normal operation. Logic thresholds are ratiometric to VCC: VIH ≥ 0.65·VCC, VIL ≤ 0.2·VCC. Max input voltage 6V referenced to GND (not limited by VCC), so 5V logic can drive SHDN while VCC runs at 3V. Do not leave floating or three-state - high-impedance drive can produce indeterminate logic levels. Wake-up time typ 15µs; shutdown delay typ 5µs. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Analog Devices Inc Maxim Integrated |+| Package | SO-8 |+| Category | Amplifiers/Comparators |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `MAX998ESA+T`+- `MAX998ESA+TEUT+T`++## CAD (KiCad official)++- Symbol: `MAX998ESA+T`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SO-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Analog Devices Inc Maxim Integrated datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588914589149384704) (10 pp, sha256 `368fd35e9b81260f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
