SN74LS390DR from lingxingic, in a SOP-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 | 0CP1 | input | Clock input of counter 1 divide-by-2 section, triggered on the HIGH-to-LOW edge. |
| 2 | 1MR | input | Asynchronous master reset input of counter 1, active HIGH; a HIGH overrides the clocks and sets the four outputs LOW. |
| 3 | 1Q0 | output | Flip-flop output Q0 of counter 1 (divide-by-2 section output). |
| 4 | 1CP1 | input | Clock input of counter 1 divide-by-5 section, triggered on the HIGH-to-LOW edge. |
| 5 | 1Q1 | output | Flip-flop output Q1 of counter 1. |
| 6 | 1Q2 | output | Flip-flop output Q2 of counter 1. |
| 7 | 1Q3 | output | Flip-flop output Q3 of counter 1. |
| 8 | GND | power_in | Ground (0 V). |
| 9 | 2Q3 | output | Flip-flop output Q3 of counter 2. |
| 10 | 2Q2 | output | Flip-flop output Q2 of counter 2. |
| 11 | 2Q1 | output | Flip-flop output Q1 of counter 2. |
| 12 | 1CP2 | input | Clock input of counter 2 divide-by-5 section, triggered on the HIGH-to-LOW edge. |
| 13 | 2Q0 | output | Flip-flop output Q0 of counter 2 (divide-by-2 section output). |
| 14 | 2MR | input | Asynchronous master reset input of counter 2, active HIGH; a HIGH overrides the clocks and sets the four outputs LOW. |
| 15 | 0CP2 | input | Clock input of counter 2 divide-by-2 section, triggered on the HIGH-to-LOW edge. |
| 16 | VCC | power_in | Supply voltage; recommended 2.0 V to 6.0 V (5.0 V typ), absolute maximum 7.0 V. |
