74VHC573MTC from onsemi, 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 | OE | input | Active-low 3-STATE output enable input; HIGH puts the eight outputs in high impedance, LOW enables them, and it does not interfere with entering new data into the latches. |
| 2 | D0 | input | Data input 0; enters the latch when LE is HIGH. |
| 3 | D1 | input | Data input 1; enters the latch when LE is HIGH. |
| 4 | D2 | input | Data input 2; enters the latch when LE is HIGH. |
| 5 | D3 | input | Data input 3; enters the latch when LE is HIGH. |
| 6 | D4 | input | Data input 4; enters the latch when LE is HIGH. |
| 7 | D5 | input | Data input 5; enters the latch when LE is HIGH. |
| 8 | D6 | input | Data input 6; enters the latch when LE is HIGH. |
| 9 | D7 | input | Data input 7; enters the latch when LE is HIGH. |
| 10 | GND | power_in | Ground, 0V reference. |
| 11 | LE | input | Latch enable input; latches are transparent when HIGH and store the D inputs when LOW. |
| 12 | O7 | tri_state | 3-STATE output 7, high impedance when OE is HIGH. |
| 13 | O6 | tri_state | 3-STATE output 6, high impedance when OE is HIGH. |
| 14 | O5 | tri_state | 3-STATE output 5, high impedance when OE is HIGH. |
| 15 | O4 | tri_state | 3-STATE output 4, high impedance when OE is HIGH. |
| 16 | O3 | tri_state | 3-STATE output 3, high impedance when OE is HIGH. |
| 17 | O2 | tri_state | 3-STATE output 2, high impedance when OE is HIGH. |
| 18 | O1 | tri_state | 3-STATE output 1, high impedance when OE is HIGH. |
| 19 | O0 | tri_state | 3-STATE output 0, high impedance when OE is HIGH. |
| 20 | VCC | power_in | Supply voltage, recommended 2.0V to 5.5V (absolute maximum -0.5V to +7.0V). |
