SN74HC373DWR from Texas Instruments, in a SOIC-20-300mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OE | input | Output enable pin, active low; when high, Q outputs are high-impedance. |
| 2 | 1Q | output | Channel 1 transparent D-latch output, tri-state. |
| 3 | 1D | input | Channel 1 transparent D-latch data input. |
| 4 | 2D | input | Channel 2 transparent D-latch data input. |
| 5 | 2Q | output | Channel 2 transparent D-latch output, tri-state. |
| 6 | 3Q | output | Channel 3 transparent D-latch output, tri-state. |
| 7 | 3D | input | Channel 3 transparent D-latch data input. |
| 8 | 4D | input | Channel 4 transparent D-latch data input. |
| 9 | 4Q | output | Channel 4 transparent D-latch output, tri-state. |
| 10 | GND | power_in | Ground reference. |
| 11 | LE | input | Latch enable pin, active high; when high, D inputs pass to Q outputs; when low, Q outputs latch current state. |
| 12 | 5Q | output | Channel 5 transparent D-latch output, tri-state. |
| 13 | 5D | input | Channel 5 transparent D-latch data input. |
| 14 | 6D | input | Channel 6 transparent D-latch data input. |
| 15 | 6Q | output | Channel 6 transparent D-latch output, tri-state. |
| 16 | 7Q | output | Channel 7 transparent D-latch output, tri-state. |
| 17 | 7D | input | Channel 7 transparent D-latch data input. |
| 18 | 8D | input | Channel 8 transparent D-latch data input. |
| 19 | 8Q | output | Channel 8 transparent D-latch output, tri-state. |
| 20 | VCC | power_in | Positive power supply. |
