SN74ALS573CDBR from Texas Instruments, in a SSOP-20-208mil. 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 | OE | input | Active-low output enable; high places the eight 3-state outputs in the high-impedance state without affecting latch contents. |
| 2 | 1D | input | Data input for latch 1. |
| 3 | 2D | input | Data input for latch 2. |
| 4 | 3D | input | Data input for latch 3. |
| 5 | 4D | input | Data input for latch 4. |
| 6 | 5D | input | Data input for latch 5. |
| 7 | 6D | input | Data input for latch 6. |
| 8 | 7D | input | Data input for latch 7. |
| 9 | 8D | input | Data input for latch 8. |
| 10 | GND | power_in | Ground. |
| 11 | LE | input | Latch enable; outputs follow D inputs while high and latch the data when low. |
| 12 | 8Q | tri_state | 3-state output of latch 8. |
| 13 | 7Q | tri_state | 3-state output of latch 7. |
| 14 | 6Q | tri_state | 3-state output of latch 6. |
| 15 | 5Q | tri_state | 3-state output of latch 5. |
| 16 | 4Q | tri_state | 3-state output of latch 4. |
| 17 | 3Q | tri_state | 3-state output of latch 3. |
| 18 | 2Q | tri_state | 3-state output of latch 2. |
| 19 | 1Q | tri_state | 3-state output of latch 1. |
| 20 | VCC | power_in | Supply voltage, 4.5 V to 5.5 V recommended (7 V absolute maximum). |
