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 | 2Y0 | bidirectional | Port 2 channel 0 analog switch terminal. Connects to 2-COM when A=0, B=0 and INH=0. Bidirectional analog/digital signal path, VIO range 0 to VCC. |+| 2 | 2Y2 | bidirectional | Port 2 channel 2 analog switch terminal. Connects to 2-COM when A=0, B=1 and INH=0. Bidirectional analog/digital signal path, VIO range 0 to VCC. |+| 3 | 2-COM | bidirectional | Port 2 common channel. Routed to one of 2Y0..2Y3 based on the A/B select inputs when INH is low. Bidirectional; when INH is high, all switches are open (high-Z). |+| 4 | 2Y3 | bidirectional | Port 2 channel 3 analog switch terminal. Connects to 2-COM when A=1, B=1 and INH=0. Bidirectional analog/digital signal path, VIO range 0 to VCC. |+| 5 | 2Y1 | bidirectional | Port 2 channel 1 analog switch terminal. Connects to 2-COM when A=1, B=0 and INH=0. Bidirectional analog/digital signal path, VIO range 0 to VCC. |+| 6 | INH | input | Active-high inhibit input. When high, all analog switches are disabled (high-Z). When low, the A/B select lines determine which Yn is connected to COM. CMOS logic-level input. |+| 7 | GND | power_in | Device ground. Also sets the lower rail of the analog switch VIO range (VIO = 0 to VCC). |+| 8 | GND | power_in | Device ground (second GND pin). Tie together with pin 7 for lowest impedance return. |+| 9 | B | input | Logic input selector B (MSB of the 2-bit channel select). Combined with A, selects which Yn channel is connected to the COM terminal on each port. CMOS logic-level input. |+| 10 | A | input | Logic input selector A (LSB of the 2-bit channel select). Combined with B, selects which Yn channel is connected to the COM terminal on each port. CMOS logic-level input. |+| 11 | 1Y3 | bidirectional | Port 1 channel 3 analog switch terminal. Connects to 1-COM when A=1, B=1 and INH=0. Bidirectional analog/digital signal path, VIO range 0 to VCC. |+| 12 | 1Y0 | bidirectional | Port 1 channel 0 analog switch terminal. Connects to 1-COM when A=0, B=0 and INH=0. Bidirectional analog/digital signal path, VIO range 0 to VCC. |+| 13 | 1-COM | bidirectional | Port 1 common channel. Routed to one of 1Y0..1Y3 based on the A/B select inputs when INH is low. Bidirectional; when INH is high, all switches are open (high-Z). |+| 14 | 1Y1 | bidirectional | Port 1 channel 1 analog switch terminal. Connects to 1-COM when A=1, B=0 and INH=0. Bidirectional analog/digital signal path, VIO range 0 to VCC. |+| 15 | 1Y2 | bidirectional | Port 1 channel 2 analog switch terminal. Connects to 1-COM when A=0, B=1 and INH=0. Bidirectional analog/digital signal path, VIO range 0 to VCC. |+| 16 | VCC | power_in | Device power supply, 1.65V to 5.5V recommended (abs max 7.0V). Sets the upper rail of the analog switch VIO range and the CMOS logic-input thresholds. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `SN74LV4052ADRD`+- `SN74LV4052ADRDR`+- `SN74LV4052ADRPW`+- `SN74LV4052ADRPWR`+- `SN74LV4052ADRRGY`+- `SN74LV4052ADRRGYR`+- `SN74LV4052ADRDYY`+- `SN74LV4052ADRDYYR`++## CAD (KiCad official)++- Symbol: `SN74LV4052ADR`+- 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/sn74lv4052a.pdf) (41 pp, sha256 `b7def37edd210805`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
