**Texas Instruments** · Signal Switches, Multiplexers, Decoders · SOIC-16

SN74HCS153DR from Texas Instruments, in a SOIC-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 | 1G | input | Channel 1 output strobe, active low; a high level forces output 1Y low regardless of the other inputs. |
| 2 | B | input | Address select B, common to both channels, selects which data input (C0 to C3) reaches the output. |
| 3 | 1C3 | input | Channel 1 data input 3. |
| 4 | 1C2 | input | Channel 1 data input 2. |
| 5 | 1C1 | input | Channel 1 data input 1. |
| 6 | 1C0 | input | Channel 1 data input 0. |
| 7 | 1Y | output | Channel 1 data output, equal to the selected data input when 1G is low. |
| 8 | GND | power_in | Ground reference for the device. |
| 9 | 2Y | output | Channel 2 data output, equal to the selected data input when 2G is low. |
| 10 | 2C0 | input | Channel 2 data input 0. |
| 11 | 2C1 | input | Channel 2 data input 1. |
| 12 | 2C2 | input | Channel 2 data input 2. |
| 13 | 2C3 | input | Channel 2 data input 3. |
| 14 | A | input | Address select A, common to both channels, selects which data input (C0 to C3) reaches the output. |
| 15 | 2G | input | Channel 2 output strobe, active low; a high level forces output 2Y low regardless of the other inputs. |
| 16 | VCC | power_in | Positive supply; recommended operating range is 2 V to 6 V. |
