SN74LS365ADR 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 | G1 | input | Active-low output-enable input G1, which is gated with G2 to enable the 3-state outputs of the hex bus driver. |
| 2 | A1 | input | Data input A1 of driver 1, non-inverting to Y1. |
| 3 | Y1 | tri_state | 3-state non-inverting output of driver 1, which follows A1 when enabled. |
| 4 | A2 | input | Data input A2 of driver 2, non-inverting to Y2. |
| 5 | Y2 | tri_state | 3-state non-inverting output of driver 2, which follows A2 when enabled. |
| 6 | A3 | input | Data input A3 of driver 3, non-inverting to Y3. |
| 7 | Y3 | tri_state | 3-state non-inverting output of driver 3, which follows A3 when enabled. |
| 8 | GND | power_in | Ground terminal; all voltage values are with respect to this network ground terminal. |
| 9 | Y4 | tri_state | 3-state non-inverting output of driver 4, which follows A4 when enabled. |
| 10 | A4 | input | Data input A4 of driver 4, non-inverting to Y4. |
| 11 | Y5 | tri_state | 3-state non-inverting output of driver 5, which follows A5 when enabled. |
| 12 | A5 | input | Data input A5 of driver 5, non-inverting to Y5. |
| 13 | Y6 | tri_state | 3-state non-inverting output of driver 6, which follows A6 when enabled. |
| 14 | A6 | input | Data input A6 of driver 6, non-inverting to Y6. |
| 15 | G2 | input | Active-low output-enable input G2, which is gated with G1 to enable the 3-state outputs of the hex bus driver. |
| 16 | VCC | power_in | Supply voltage pin; absolute maximum rating is 7 V with respect to ground. |
