SN74LVC1G14 Schmitt Inverter

@@ -0,0 +1,56 @@+# SN74LVC1G14++**Texas Instruments** · Logic Gate · SOT-23-5++The SN74LVC1G14 is a single Schmitt-trigger inverter in the LVC family. Its input hysteresis cleans up slow or noisy signals into fast, clean logic edges, and the single-gate package drops in exactly where one inverter is needed. It runs from 1.65 V to 5.5 V and is 5 V tolerant on the input.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | NC | unconnected | No internal connection. May be tied to any signal or voltage source (including ground); TI recommends soldering to the board for mechanical retention. |+| 2 | A | input | Schmitt-trigger signal input. VT+ ≈ 1.5V and VT- ≈ 0.84V at VCC=3V (hysteresis ΔVT ≈ 0.56V typ). Accepts input voltages up to 5.5V regardless of VCC (5V-tolerant). |+| 3 | GND | power_in | Ground reference (0V) for the device. |+| 4 | Y | output | Inverted Schmitt-trigger output, Y = /A. Push-pull CMOS drive of ±24 mA at VCC=3.3V (±32 mA at 4.5V). |+| 5 | VCC | power_in | Positive supply, 1.65V to 5.5V operating (1.5V min for data retention only). Ioff supports partial-power-down: outputs are disabled when the device is unpowered to prevent backflow. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Single Schmitt-trigger inverter |+| Logic family | LVC (CMOS) |+| Supply voltage | 1.65 V to 5.5 V |+| Input hysteresis | Schmitt-trigger |+| Input tolerance | 5 V tolerant |+| Propagation delay | 4.6 ns typ at 3.3 V |+| Operating temperature | -40 C to 125 C |++## Ordering variants++- `SN74LVC1G14DBVR`+- `SN74LVC1G14DBVT`+- `SN74LVC1G14DCKR`+- `SN74LVC1G14DCKT`+- `SN74LVC1G14DRLR`+- `SN74LVC1G14DRYR`+- `SN74LVC1G14DSFR`+- `SN74LVC1G14DPWR`+- `SN74LVC1G14YZPR`+- `SN74LVC1G14YZVR`++## CAD (KiCad official)++- Symbol: `sn74lvc1g14.kicad_sym`+- Footprint: `sn74lvc1g14.kicad_mod`+- 3D model: SOT-23-5 body from KiCad `Package_TO_SOT_SMD/SOT-23-5`.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/sn74lvc1g14.pdf) (51 pp, sha256 `f1da484847bc3c14`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
