TC74HC373APF from TOSHIBA, in a DIP-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 output enable input; when high, the eight outputs are in a high-impedance state. |
| 2 | Q0 | tri_state | 3-state latch output 0, high impedance when OE is high. |
| 3 | D0 | input | Data input 0 to the D-type latch. |
| 4 | D1 | input | Data input 1 to the D-type latch. |
| 5 | Q1 | tri_state | 3-state latch output 1, high impedance when OE is high. |
| 6 | Q2 | tri_state | 3-state latch output 2, high impedance when OE is high. |
| 7 | D2 | input | Data input 2 to the D-type latch. |
| 8 | D3 | input | Data input 3 to the D-type latch. |
| 9 | Q3 | tri_state | 3-state latch output 3, high impedance when OE is high. |
| 10 | GND | power_in | Ground pin; unused inputs must be tied to VCC or GND. |
| 11 | LE | input | Latch enable input; outputs follow D when high and are latched when LE goes low. |
| 12 | Q4 | tri_state | 3-state latch output 4, high impedance when OE is high. |
| 13 | D4 | input | Data input 4 to the D-type latch. |
| 14 | D5 | input | Data input 5 to the D-type latch. |
| 15 | Q5 | tri_state | 3-state latch output 5, high impedance when OE is high. |
| 16 | Q6 | tri_state | 3-state latch output 6, high impedance when OE is high. |
| 17 | D6 | input | Data input 6 to the D-type latch. |
| 18 | D7 | input | Data input 7 to the D-type latch. |
| 19 | Q7 | tri_state | 3-state latch output 7, high impedance when OE is high. |
| 20 | VCC | power_in | Supply voltage pin, operating range 2 to 6 V (absolute maximum -0.5 to 7 V). |
