SN74AC241DWR 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 | 1OE | input | Output enable 1 (active low); when 1OE is high the 1Y outputs are placed in the high-impedance state, and when it is low the 1Y outputs pass the 1A data. |
| 2 | 1A1 | input | Data input 1A1 for the 1Y1 buffer, passed noninverted to 1Y1 when 1OE is low. |
| 3 | 2Y4 | output | Output 2Y4 of the second buffer section, which goes high impedance when 2OE is low; continuous output current is limited to ±50 mA. |
| 4 | 1A2 | input | Data input 1A2 for the 1Y2 buffer, passed noninverted to 1Y2 when 1OE is low. |
| 5 | 2Y3 | output | Output 2Y3 of the second buffer section, which goes high impedance when 2OE is low. |
| 6 | 1A3 | input | Data input 1A3 for the 1Y3 buffer, passed noninverted to 1Y3 when 1OE is low. |
| 7 | 2Y2 | output | Output 2Y2 of the second buffer section, which goes high impedance when 2OE is low. |
| 8 | 1A4 | input | Data input 1A4 for the 1Y4 buffer, passed noninverted to 1Y4 when 1OE is low. |
| 9 | 2Y1 | output | Output 2Y1 of the second buffer section, which goes high impedance when 2OE is low. |
| 10 | GND | power_in | Ground reference pin; continuous current through VCC or GND is limited to ±200 mA. |
| 11 | 2A1 | input | Data input 2A1 for the 2Y1 buffer, passed noninverted to 2Y1 when 2OE is high. |
| 12 | 1Y4 | output | Output 1Y4 of the first buffer section, which goes high impedance when 1OE is high. |
| 13 | 2A2 | input | Data input 2A2 for the 2Y2 buffer, passed noninverted to 2Y2 when 2OE is high. |
| 14 | 1Y3 | output | Output 1Y3 of the first buffer section, which goes high impedance when 1OE is high. |
| 15 | 2A3 | input | Data input 2A3 for the 2Y3 buffer, passed noninverted to 2Y3 when 2OE is high. |
| 16 | 1Y2 | output | Output 1Y2 of the first buffer section, which goes high impedance when 1OE is high. |
| 17 | 2A4 | input | Data input 2A4 for the 2Y4 buffer, passed noninverted to 2Y4 when 2OE is high. |
| 18 | 1Y1 | output | Output 1Y1 of the first buffer section, which goes high impedance when 1OE is high. |
| 19 | 2OE | input | Output enable 2 (active high); when 2OE is low the 2Y outputs are placed in the high-impedance state. |
| 20 | VCC | power_in | Supply pin; the recommended supply range is 2 V to 6 V. |
