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 | 1Y | bidirectional | Y-switch channel 1 analog I/O (independent end). Connected to Y-COM when A=1 and INH=0. Signal range 0 to V_CC. |+| 2 | 0Y | bidirectional | Y-switch channel 0 analog I/O (independent end). Connected to Y-COM when A=0 and INH=0. Signal range 0 to V_CC. |+| 3 | 1Z | bidirectional | Z-switch channel 1 analog I/O (independent end). Connected to Z-COM when C=1 and INH=0. Signal range 0 to V_CC. |+| 4 | Z-COM | bidirectional | Z-switch common analog I/O (pole end). Routed to 0Z or 1Z based on select input C (INH must be low). |+| 5 | 0Z | bidirectional | Z-switch channel 0 analog I/O (independent end). Connected to Z-COM when C=0 and INH=0. Signal range 0 to V_CC. |+| 6 | INH | input | Active-high inhibit. When high, all three switches are turned OFF regardless of A/B/C. CMOS logic input, V_IH ≥ 2.0 V at V_CC = 3.0 V. |+| 7 | GND | power_in | Ground / negative supply reference. Also sets the lower bound of the analog switch signal range. |+| 8 | GND | power_in | Ground / negative supply reference (second GND pin). Tie to the same ground plane as pin 7. |+| 9 | C | input | Select input C for the Z-switch. Selects 0Z (C=0) or 1Z (C=1) when INH is low. |+| 10 | B | input | Select input B for the X-switch. Selects 0X (B=0) or 1X (B=1) when INH is low. |+| 11 | A | input | Select input A for the Y-switch. Selects 0Y (A=0) or 1Y (A=1) when INH is low. |+| 12 | 0X | bidirectional | X-switch channel 0 analog I/O (independent end). Connected to X-COM when B=0 and INH=0. Signal range 0 to V_CC. |+| 13 | 1X | bidirectional | X-switch channel 1 analog I/O (independent end). Connected to X-COM when B=1 and INH=0. Signal range 0 to V_CC. |+| 14 | X-COM | bidirectional | X-switch common analog I/O (pole end). Routed to 0X or 1X based on select input B (INH must be low). |+| 15 | Y-COM | bidirectional | Y-switch common analog I/O (pole end). Routed to 0Y or 1Y based on select input A (INH must be low). |+| 16 | VCC | power_in | Positive supply, 2.0 to 5.5 V operating. Also sets the upper bound of the analog switch signal range. Decouple with a 0.1 µF ceramic close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TOSHIBA |+| Package | TSSOP-16-175mil |+| Category | Interface |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `74VHC4053AFT`++## CAD (KiCad official)++- Symbol: `74VHC4053AFT`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-16-175mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [TOSHIBA datasheet](docs/74vhc4053aft-datasheet.pdf) (15 pp, sha256 `2b1c02a2c007eb02`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
