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 | Analog switch B independent I/O 1. Bidirectional analog signal path to common ZB when SB=H and E=L. Signal range VEE to VDD. |+| 2 | Y0B | bidirectional | Analog switch B independent I/O 0. Bidirectional analog signal path to common ZB when SB=L and E=L. Signal range VEE to VDD. |+| 3 | Y1C | bidirectional | Analog switch C independent I/O 1. Bidirectional analog signal path to common ZC when SC=H and E=L. Signal range VEE to VDD. |+| 4 | ZC | bidirectional | Analog switch C common I/O. Connects to Y0C or Y1C selected by SC when E=L. RON typ 80 Ω at VDD-VEE=9 V. |+| 5 | Y0C | bidirectional | Analog switch C independent I/O 0. Bidirectional analog signal path to common ZC when SC=L and E=L. Signal range VEE to VDD. |+| 6 | ~{E} | input | Active-low enable input. When low, one channel per switch is connected as selected by Sn; when high, all switches are in high-impedance disconnect (independent of Sn). |+| 7 | VEE | power_in | Negative analog supply for the switch elements. Recommended operating range -6.0 V to 0 V; sets the lower bound of the analog signal swing. |+| 8 | VSS | power_in | Digital ground reference for the SA/SB/SC and E control inputs. Typically tied to VEE for digital-multiplexer use. |+| 9 | SC | input | Channel-select digital input for switch C. Selects Y0C (SC=L) or Y1C (SC=H) to connect to ZC when E is low. |+| 10 | SB | input | Channel-select digital input for switch B. Selects Y0B (SB=L) or Y1B (SB=H) to connect to ZB when E is low. |+| 11 | SA | input | Channel-select digital input for switch A. Selects Y0A (SA=L) or Y1A (SA=H) to connect to ZA when E is low. |+| 12 | Y0A | bidirectional | Analog switch A independent I/O 0. Bidirectional analog signal path to common ZA when SA=L and E=L. Signal range VEE to VDD. |+| 13 | Y1A | bidirectional | Analog switch A independent I/O 1. Bidirectional analog signal path to common ZA when SA=H and E=L. Signal range VEE to VDD. |+| 14 | ZA | bidirectional | Analog switch A common I/O. Connects to Y0A or Y1A selected by SA when E=L. RON typ 80 Ω at VDD-VEE=9 V. |+| 15 | ZB | bidirectional | Analog switch B common I/O. Connects to Y0B or Y1B selected by SB when E=L. RON typ 80 Ω at VDD-VEE=9 V. |+| 16 | VDD | power_in | Positive supply. Recommended 3.0-9.0 V with respect to VEE (absolute max 12 V). Powers the digital level converter/decoder and sets the upper bound of the analog signal swing. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | TSSOP-16 |+| Category | Comm/UART |+| Pins | 16 |++## Ordering variants++- `74HC4053MT/TR`+- `74HC4053MTN`+- `74HC4053MTM/TR`+- `74HC4053MTMS/TR`+- `74HC4053MTLQ/TR`++## CAD (KiCad official)++- Symbol: `74HC4053MT`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/74hc4053mt-datasheet.pdf) (14 pp, sha256 `4dd2103c9b371c7c`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
