lingxingic · Counters, Dividers · DIP-16
SN74LS163N 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 | MR | input | Master reset input, active LOW; the pin table calls it asynchronous, but the function table and text say a LOW sets Q0 to Q3 LOW after the next positive-going CP transition, regardless of PĒ, CET and CEP. |
| 2 | CP | input | Clock input, positive-going (LOW-to-HIGH) edge triggered; all flip-flops clock simultaneously on this edge. |
| 3 | D0 | input | Data input 0; loaded into the counter on the positive-going clock edge when PĒ is LOW, and inputs include clamp diodes. |
| 4 | D1 | input | Data input 1; loaded into the counter on the positive-going clock edge when PĒ is LOW, and inputs include clamp diodes. |
| 5 | D2 | input | Data input 2; loaded into the counter on the positive-going clock edge when PĒ is LOW, and inputs include clamp diodes. |
| 6 | D3 | input | Data input 3; loaded into the counter on the positive-going clock edge when PĒ is LOW, and inputs include clamp diodes. |
| 7 | CEP | input | Count enable input; both CEP and CET must be HIGH for the counter to count. |
| 8 | GND | power_in | Ground reference (0 V). |
| 9 | PE | input | Parallel enable input, active LOW; a LOW loads D0 to D3 into the counter on the positive clock edge, regardless of the CEP and CET levels. |
| 10 | CET | input | Count enable carry input; it is fed forward to enable the terminal count output TC, and both CEP and CET must be HIGH to count. |
| 11 | Q3 | output | Flip-flop output bit 3 of the 4-bit counter. |
| 12 | Q2 | output | Flip-flop output bit 2 of the 4-bit counter. |
| 13 | Q1 | output | Flip-flop output bit 1 of the 4-bit counter. |
| 14 | Q0 | output | Flip-flop output bit 0 of the 4-bit counter. |
| 15 | TC | output | Terminal count output; HIGH when CET is HIGH and the counter is at terminal count (HHHH), giving a HIGH pulse about as long as a HIGH on Q0 to enable the next cascaded stage. |
| 16 | VCC | power_in | Supply voltage; recommended range 2.0 V to 6.0 V (5.0 V typical), absolute maximum 7.0 V. |
