SN74AHC541DWR from Texas Instruments, in a SOIC-20-300mil. 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 | OE1 | input | Output Enable 1 (active low); when high, all corresponding Y outputs are in high-impedance state. |
| 2 | A1 | input | A1 Input; non-inverted data input to octal buffer/driver. |
| 3 | A2 | input | A2 Input; non-inverted data input to octal buffer/driver. |
| 4 | A3 | input | A3 Input; non-inverted data input to octal buffer/driver. |
| 5 | A4 | input | A4 Input; non-inverted data input to octal buffer/driver. |
| 6 | A5 | input | A5 Input; non-inverted data input to octal buffer/driver. |
| 7 | A6 | input | A6 Input; non-inverted data input to octal buffer/driver. |
| 8 | A7 | input | A7 Input; non-inverted data input to octal buffer/driver. |
| 9 | A8 | input | A8 Input; non-inverted data input to octal buffer/driver. |
| 10 | GND | power_in | Ground; return path for supply current. |
| 11 | Y8 | tri_state | Y8 Output (tri-state); non-inverted data output when OE is low, high-impedance when OE is high. |
| 12 | Y7 | tri_state | Y7 Output (tri-state); non-inverted data output when OE is low, high-impedance when OE is high. |
| 13 | Y6 | tri_state | Y6 Output (tri-state); non-inverted data output when OE is low, high-impedance when OE is high. |
| 14 | Y5 | tri_state | Y5 Output (tri-state); non-inverted data output when OE is low, high-impedance when OE is high. |
| 15 | Y4 | tri_state | Y4 Output (tri-state); non-inverted data output when OE is low, high-impedance when OE is high. |
| 16 | Y3 | tri_state | Y3 Output (tri-state); non-inverted data output when OE is low, high-impedance when OE is high. |
| 17 | Y2 | tri_state | Y2 Output (tri-state); non-inverted data output when OE is low, high-impedance when OE is high. |
| 18 | Y1 | tri_state | Y1 Output (tri-state); non-inverted data output when OE is low, high-impedance when OE is high. |
| 19 | OE2 | input | Output Enable 2 (active low); when high, all corresponding Y outputs are in high-impedance state. |
| 20 | VCC | power_in | Power Supply; positive supply voltage, operating range 2 V to 5.5 V. |
