SN74LVC157AQDRG4Q1 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 | A/B | input | Address select input that chooses whether channel data from the A or B inputs is routed to the Y outputs. |
| 2 | 1A | input | Channel 1 data input A. |
| 3 | 1B | input | Channel 1 data input B. |
| 4 | 1Y | output | Channel 1 data output. |
| 5 | 2A | input | Channel 2 data input A. |
| 6 | 2B | input | Channel 2 data input B. |
| 7 | 2Y | output | Channel 2 data output. |
| 8 | GND | power_in | Ground reference for the device. |
| 9 | 3Y | output | Channel 3 data output. |
| 10 | 3B | input | Channel 3 data input B. |
| 11 | 3A | input | Channel 3 data input A. |
| 12 | 4Y | output | Channel 4 data output. |
| 13 | 4B | input | Channel 4 data input B. |
| 14 | 4A | input | Channel 4 data input A. |
| 15 | G | input | Active-low output strobe; when G is high all outputs are forced low. |
| 16 | VCC | power_in | Positive supply; recommended operating range is 2 V to 3.6 V. |
