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 | Y1B | bidirectional | Independent analog I/O of channel B, switch position 1. Bidirectional analog pin selectable to Zb when Sb=H and E(bar)=L. |+| 2 | Y0B | bidirectional | Independent analog I/O of channel B, switch position 0. Bidirectional analog pin selectable to Zb when Sb=L and E(bar)=L. |+| 3 | Y1C | bidirectional | Independent analog I/O of channel C, switch position 1. Bidirectional analog pin selectable to Zc when Sc=H and E(bar)=L. |+| 4 | ZC | bidirectional | Common analog I/O of channel C. Routed to Y0C or Y1C via Sc when enable E(bar)=L. Ron typ ~115 Ω at VDD-VEE=5 V. |+| 5 | Y0C | bidirectional | Independent analog I/O of channel C, switch position 0. Bidirectional analog pin selectable to Zc when Sc=L and E(bar)=L. |+| 6 | E | input | Active-low enable input (E-bar). When LOW, one switch per section is selected by Sn; when HIGH all switches are OFF (high impedance). Digital input referenced to VDD/VSS. |+| 7 | VEE | power_in | Negative analog supply for the switch channels. Range -6 V to 0 V; may be tied to VSS for single-supply digital mux operation. VDD-VEE ≤ 9 V. |+| 8 | VSS | power_in | Ground / digital logic negative supply. Reference for the Sn and E(bar) digital control inputs. |+| 9 | SC | input | Channel C select input. Sc=L selects Y0C→Zc, Sc=H selects Y1C→Zc when E(bar)=L. Digital input referenced to VDD/VSS. |+| 10 | SB | input | Channel B select input. Sb=L selects Y0B→Zb, Sb=H selects Y1B→Zb when E(bar)=L. |+| 11 | SA | input | Channel A select input. Sa=L selects Y0A→Za, Sa=H selects Y1A→Za when E(bar)=L. |+| 12 | Y0A | bidirectional | Independent analog I/O of channel A, switch position 0. Bidirectional analog pin selectable to Za when Sa=L and E(bar)=L. |+| 13 | Y1A | bidirectional | Independent analog I/O of channel A, switch position 1. Bidirectional analog pin selectable to Za when Sa=H and E(bar)=L. |+| 14 | ZA | bidirectional | Common analog I/O of channel A. Routed to Y0A or Y1A via Sa when enable E(bar)=L. |+| 15 | ZB | bidirectional | Common analog I/O of channel B. Routed to Y0B or Y1B via Sb when enable E(bar)=L. |+| 16 | VDD | power_in | Positive supply voltage. Recommended 3.0-9.0 V (typ 5.0 V). VDD-VEE must not exceed 9 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | SOP-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++- `74HC4053MM/TR`+- `74HC4053MN`+- `74HC4053MMT/TR`+- `74HC4053MMS/TR`+- `74HC4053MLQ/TR`++## CAD (KiCad official)++- Symbol: `74HC4053M`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/74hc4053m-datasheet.pdf) (14 pp, sha256 `4dd2103c9b371c7c`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
