SN74ACT241PWR from Texas Instruments, in a TSSOP-20. 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 low the 1Y outputs pass the 1A data, and when 1OE is high the 1Y outputs go to the high-impedance state. |
| 2 | 1A1 | input | Data input 1A1 of buffer channel 1; inputs are TTL-compatible and accept voltages up to 5.5 V. |
| 3 | 2Y4 | tri_state | 3-state output 2Y4 of buffer channel 2, high-impedance when 2OE is low. |
| 4 | 1A2 | input | Data input 1A2 of buffer channel 1; inputs are TTL-compatible and accept voltages up to 5.5 V. |
| 5 | 2Y3 | tri_state | 3-state output 2Y3 of buffer channel 2, high-impedance when 2OE is low. |
| 6 | 1A3 | input | Data input 1A3 of buffer channel 1; inputs are TTL-compatible and accept voltages up to 5.5 V. |
| 7 | 2Y2 | tri_state | 3-state output 2Y2 of buffer channel 2, high-impedance when 2OE is low. |
| 8 | 1A4 | input | Data input 1A4 of buffer channel 1; inputs are TTL-compatible and accept voltages up to 5.5 V. |
| 9 | 2Y1 | tri_state | 3-state output 2Y1 of buffer channel 2, high-impedance when 2OE is low. |
| 10 | GND | power_in | Ground pin. |
| 11 | 2A1 | input | Data input 2A1 of buffer channel 2; inputs are TTL-compatible and accept voltages up to 5.5 V. |
| 12 | 1Y4 | tri_state | 3-state output 1Y4 of buffer channel 1, high-impedance when 1OE is high. |
| 13 | 2A2 | input | Data input 2A2 of buffer channel 2; inputs are TTL-compatible and accept voltages up to 5.5 V. |
| 14 | 1Y3 | tri_state | 3-state output 1Y3 of buffer channel 1, high-impedance when 1OE is high. |
| 15 | 2A3 | input | Data input 2A3 of buffer channel 2; inputs are TTL-compatible and accept voltages up to 5.5 V. |
| 16 | 1Y2 | tri_state | 3-state output 1Y2 of buffer channel 1, high-impedance when 1OE is high. |
| 17 | 2A4 | input | Data input 2A4 of buffer channel 2; inputs are TTL-compatible and accept voltages up to 5.5 V. |
| 18 | 1Y1 | tri_state | 3-state output 1Y1 of buffer channel 1, high-impedance when 1OE is high. |
| 19 | 2OE | input | Output enable 2 (active high): when 2OE is high the 2Y outputs pass the 2A data, and when 2OE is low the 2Y outputs go to the high-impedance state. |
| 20 | VCC | power_in | Supply voltage, 4.5 V to 5.5 V recommended; bypass close to this pin per the datasheet guidance (0.1 µF for a single supply). |
