**XBLW** · Analog Switches, Multiplexers · SOP-16

CD4052BDTR from XBLW, in a SOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 2Y0 | bidirectional | Independent input or output of multiplexer 2, channel 0 (analog switch to 2Z). |
| 2 | 2Y2 | bidirectional | Independent input or output of multiplexer 2, channel 2 (analog switch to 2Z). |
| 3 | 2Z | bidirectional | Common output or input of multiplexer 2. |
| 4 | 2Y3 | bidirectional | Independent input or output of multiplexer 2, channel 3 (analog switch to 2Z). |
| 5 | 2Y1 | bidirectional | Independent input or output of multiplexer 2, channel 1 (analog switch to 2Z). |
| 6 | E | input | Active-LOW enable input; when HIGH all switches are off regardless of S1 and S2. |
| 7 | VEE | power_in | Negative supply voltage for the analog switches, recommended -6.0 V to 0 V; connect to VSS for digital multiplexing. |
| 8 | VSS | power_in | Ground (0 V). |
| 9 | S2 | input | Channel select input S2, common to both multiplexers. |
| 10 | S1 | input | Channel select input S1, common to both multiplexers. |
| 11 | 1Y3 | bidirectional | Independent input or output of multiplexer 1, channel 3 (analog switch to 1Z). |
| 12 | 1Y0 | bidirectional | Independent input or output of multiplexer 1, channel 0 (analog switch to 1Z). |
| 13 | 1Z | bidirectional | Common output or input of multiplexer 1. |
| 14 | 1Y1 | bidirectional | Independent input or output of multiplexer 1, channel 1 (analog switch to 1Z). |
| 15 | 1Y2 | bidirectional | Independent input or output of multiplexer 1, channel 2 (analog switch to 1Z). |
| 16 | VDD | power_in | Positive supply voltage, 3 V to 9 V recommended (absolute max +12 V); VDD-VEE may not exceed 9 V. |
