SN74LVC541AQDWRQ1 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 input, active low; when high or OE2 is high, all eight outputs (Y1-Y8) are driven to high-impedance state. |
| 2 | A1 | input | Data input A1; accepts 0 to 5.5 V and buffers to output Y1 when both OE1 and OE2 are low. |
| 3 | A2 | input | Data input A2; accepts 0 to 5.5 V and buffers to output Y2 when both OE1 and OE2 are low. |
| 4 | A3 | input | Data input A3; accepts 0 to 5.5 V and buffers to output Y3 when both OE1 and OE2 are low. |
| 5 | A4 | input | Data input A4; accepts 0 to 5.5 V and buffers to output Y4 when both OE1 and OE2 are low. |
| 6 | A5 | input | Data input A5; accepts 0 to 5.5 V and buffers to output Y5 when both OE1 and OE2 are low. |
| 7 | A6 | input | Data input A6; accepts 0 to 5.5 V and buffers to output Y6 when both OE1 and OE2 are low. |
| 8 | A7 | input | Data input A7; accepts 0 to 5.5 V and buffers to output Y7 when both OE1 and OE2 are low. |
| 9 | A8 | input | Data input A8; accepts 0 to 5.5 V and buffers to output Y8 when both OE1 and OE2 are low. |
| 10 | GND | power_in | Ground; negative supply reference. |
| 11 | Y8 | tri_state | 3-state output Y8; buffers input A8 when OE1 and OE2 are low; high-impedance when either output enable is high. |
| 12 | Y7 | tri_state | 3-state output Y7; buffers input A7 when OE1 and OE2 are low; high-impedance when either output enable is high. |
| 13 | Y6 | tri_state | 3-state output Y6; buffers input A6 when OE1 and OE2 are low; high-impedance when either output enable is high. |
| 14 | Y5 | tri_state | 3-state output Y5; buffers input A5 when OE1 and OE2 are low; high-impedance when either output enable is high. |
| 15 | Y4 | tri_state | 3-state output Y4; buffers input A4 when OE1 and OE2 are low; high-impedance when either output enable is high. |
| 16 | Y3 | tri_state | 3-state output Y3; buffers input A3 when OE1 and OE2 are low; high-impedance when either output enable is high. |
| 17 | Y2 | tri_state | 3-state output Y2; buffers input A2 when OE1 and OE2 are low; high-impedance when either output enable is high. |
| 18 | Y1 | tri_state | 3-state output Y1; buffers input A1 when OE1 and OE2 are low; high-impedance when either output enable is high. |
| 19 | OE2 | input | Output enable 2 input, active low; when high or OE1 is high, all eight outputs (Y1-Y8) are driven to high-impedance state. |
| 20 | VCC | power_in | Supply voltage; recommended operating range 2.0 to 3.6 V; inputs tolerate up to 5.5 V. |
