SN74LS192N from lingxingic, in a DIP-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 | D1 | input | Parallel data input D1, loaded into flip-flop Q1 when PL is LOW. |
| 2 | Q1 | output | Flip-flop output 1 of the counter; it is forced LOW by a HIGH on MR. |
| 3 | Q0 | output | Flip-flop output 0 of the counter; it is forced LOW by a HIGH on MR. |
| 4 | CPD | input | Count-down clock input, edge triggered on the LOW-to-HIGH transition; the counter counts down when CPU is held HIGH. |
| 5 | CPU | input | Count-up clock input, edge triggered on the LOW-to-HIGH transition; the counter counts up when CPD is held HIGH. |
| 6 | Q2 | output | Flip-flop output 2 of the counter; it is forced LOW by a HIGH on MR. |
| 7 | Q3 | output | Flip-flop output 3 of the counter; it is forced LOW by a HIGH on MR. |
| 8 | GND | power_in | Ground reference (0 V) for all voltages in the datasheet. |
| 9 | D3 | input | Parallel data input D3, loaded into flip-flop Q3 when PL is LOW. |
| 10 | D2 | input | Parallel data input D2, loaded into flip-flop Q2 when PL is LOW. |
| 11 | PL | input | Asynchronous parallel load input, active LOW; it loads D0 to D3 into the counter regardless of the clock inputs. |
| 12 | TCU | output | Terminal count up (carry) output, active LOW; it goes LOW at count 15 on the next HIGH-to-LOW transition of CPU. |
| 13 | TCD | output | Terminal count down (borrow) output, active LOW; it goes LOW in the zero state when CPD goes LOW. |
| 14 | MR | input | Asynchronous master reset input, active HIGH; it sets Q0 to Q3 LOW and overrides both clock inputs. |
| 15 | D0 | input | Parallel data input D0, loaded into flip-flop Q0 when PL is LOW. |
| 16 | VCC | power_in | Supply voltage; the recommended range is 2.0 V to 6.0 V, with 5.0 V typical. |
