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

CD4053BDTR 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 | 2Y1 | bidirectional | Independent input or output of switch 2 (channel 1), connected to 2Z when selected. |
| 2 | 2Y0 | bidirectional | Independent input or output of switch 2 (channel 0), connected to 2Z when selected. |
| 3 | 3Y1 | bidirectional | Independent input or output of switch 3 (channel 1), connected to 3Z when selected. |
| 4 | 3Z | bidirectional | Common output or input of switch 3, swinging between VDD and VEE. |
| 5 | 3Y0 | bidirectional | Independent input or output of switch 3 (channel 0), connected to 3Z when selected. |
| 6 | E̅ | input | Enable input, active LOW; a HIGH makes all switches high-impedance OFF regardless of Sn. |
| 7 | VEE | power_in | Negative supply voltage for the switches (analog negative limit); connected to VSS for digital multiplexer use, and VDD-VEE may not exceed 9V. |
| 8 | VSS | power_in | Ground (0V), supply connection for the digital control inputs; VDD to VSS range is 3V to 9V. |
| 9 | S3 | input | Select input for switch 3. |
| 10 | S2 | input | Select input for switch 2. |
| 11 | S1 | input | Select input for switch 1. |
| 12 | 1Y0 | bidirectional | Independent input or output of switch 1 (channel 0), connected to 1Z when selected. |
| 13 | 1Y1 | bidirectional | Independent input or output of switch 1 (channel 1), connected to 1Z when selected. |
| 14 | 1Z | bidirectional | Common output or input of switch 1, swinging between VDD and VEE. |
| 15 | 2Z | bidirectional | Common output or input of switch 2, swinging between VDD and VEE. |
| 16 | VDD | power_in | Positive supply voltage; VDD to VSS range is 3V to 9V and VDD-VEE may not exceed 9V. |
