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 | A4 | bidirectional | Analog channel 4 in/out. Bidirectional analog switch terminal; connects to COM when S2:S0 = 100 and E is low. Signal range VEE to VCC, up to 10 V pk-pk. |+| 2 | A6 | bidirectional | Analog channel 6 in/out. Bidirectional analog switch terminal; connects to COM when S2:S0 = 110 and E is low. |+| 3 | COM | bidirectional | Common analog out/in. The shared switch terminal that connects to one of A0-A7 based on the S0-S2 select code when E is low. |+| 4 | A7 | bidirectional | Analog channel 7 in/out. Bidirectional analog switch terminal; connects to COM when S2:S0 = 111 and E is low. |+| 5 | A5 | bidirectional | Analog channel 5 in/out. Bidirectional analog switch terminal; connects to COM when S2:S0 = 101 and E is low. |+| 6 | ~{E} | input | Enable, active low. When E is high, all eight channels are OFF (disconnected from COM) regardless of the S0-S2 code. Digital input referenced to VCC/GND. |+| 7 | VEE | power_in | Negative analog supply. Sets the lower limit of the analog signal range. Typically 0 V for unipolar operation or up to -6 V for bipolar operation; VCC - VEE must not exceed 10 V. |+| 8 | GND | power_in | Digital ground reference for control inputs (S0-S2, E). Also the reference for the VCC digital supply. |+| 9 | S2 | input | Channel-select bit 2 (MSB). Together with S1 and S0 selects which of A0-A7 is connected to COM. CMOS digital input. |+| 10 | S1 | input | Channel-select bit 1. Digital input to the binary-to-1-of-8 decoder. |+| 11 | S0 | input | Channel-select bit 0 (LSB). Digital input to the binary-to-1-of-8 decoder. |+| 12 | A3 | bidirectional | Analog channel 3 in/out. Connects to COM when S2:S0 = 011 and E is low. |+| 13 | A0 | bidirectional | Analog channel 0 in/out. Connects to COM when S2:S0 = 000 and E is low. |+| 14 | A1 | bidirectional | Analog channel 1 in/out. Connects to COM when S2:S0 = 001 and E is low. |+| 15 | A2 | bidirectional | Analog channel 2 in/out. Connects to COM when S2:S0 = 010 and E is low. |+| 16 | VCC | power_in | Positive supply. HC types: 2 V to 6 V; HCT types: 4.5 V to 5.5 V. Also sets the upper analog signal rail; VCC - VEE must not exceed 10 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `CD74HC4051M96M`+- `CD74HC4051M96M96`+- `CD74HC4051M96E`+- `CD74HC4051M96N`+- `CD74HC4051M96F`+- `CD74HC4051M96J`+- `CD74HC4051M96NS`+- `CD74HC4051M96PW`++## CAD (KiCad official)++- Symbol: `CD74HC4051M96`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/cd74hc4051m96.pdf) (45 pp, sha256 `b9165a634703374a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
