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 | ENA | input | Enable for Driver A. Active-high, low-threshold logic input (VEH ~1.6V, VEL ~1.3V, 0.3V hysteresis). Internal pull-up (~1.5 MΩ) to VDD lets the pin float for normal operation; driving below VEL disables and forces OUTA low regardless of INA. |+| 2 | INA | input | Input for Driver A. High-impedance, low-threshold TTL/CMOS-compatible logic input with hysteresis (VIH ~1.6V, VIL ~1.3V). Input voltage range GND-0.3V to VDD+0.3V; drives OUTA (non-inverting for MCP14A0454). |+| 3 | GND | power_in | Device ground; common return for input and output stages. Must have a low-impedance connection to the bias supply source return since high peak currents flow through it while discharging the capacitive load. |+| 4 | INB | input | Input for Driver B. High-impedance, low-threshold TTL/CMOS-compatible logic input with hysteresis (VIH ~1.6V, VIL ~1.3V). Input voltage range GND-0.3V to VDD+0.3V; drives OUTB (non-inverting for MCP14A0454). |+| 5 | OUTB | output | Push-pull gate-drive output for channel B (non-inverting on MCP14A0454; follows INB). CMOS output sources/sinks up to 4.5A peak (VDD=18V) with ROH ~1.7Ω / ROL ~1.3Ω typical. Latch-up protected to 500 mA reverse current. |+| 6 | VDD | power_in | Bias supply input for the driver; 4.5V to 18V operating range (absolute max +20V). Must be decoupled to GND with a local low-ESR bypass capacitor to source the peak gate-drive currents delivered to the load. |+| 7 | OUTA | output | Push-pull gate-drive output for channel A (non-inverting on MCP14A0454; follows INA). CMOS output sources/sinks up to 4.5A peak (VDD=18V) with ROH ~1.7Ω / ROL ~1.3Ω typical. Latch-up protected to 500 mA reverse current. |+| 8 | ENB | input | Enable for Driver B. Active-high, low-threshold logic input (VEH ~1.6V, VEL ~1.3V, 0.3V hysteresis). Internal pull-up (~1.5 MΩ) to VDD lets the pin float for normal operation; driving below VEL disables and forces OUTB low regardless of INB. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip Tech |+| Package | MSOP-8 |+| Category | Motor Driver ICs |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `MCP14A0454-EE/MS`+- `MCP14A0454-ET-E/MS`+- `MCP14A0454-EE/SN`+- `MCP14A0454-ET-E/SN`+- `MCP14A0454-EE/MNY`+- `MCP14A0454-ET-E/MNY`++## CAD (KiCad official)++- Symbol: `MCP14A0454-E`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Microchip Tech datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8589040321149329408) (34 pp, sha256 `1a3d8d6619869444`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
