# SN74HC160N

**XBLW** · Counters, Dividers · DIP-16

SN74HC160N from XBLW, 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 | Asynchronous master reset, active LOW; a LOW sets Q0 to Q3 LOW regardless of CP, PE, CET and CEP. |
| 2 | CP | input | Clock input, LOW-to-HIGH edge triggered. |
| 3 | D0 | input | Data input, loaded into the counter on the positive-going clock edge when PE is LOW. |
| 4 | D1 | input | Data input, loaded into the counter on the positive-going clock edge when PE is LOW. |
| 5 | D2 | input | Data input, loaded into the counter on the positive-going clock edge when PE is LOW. |
| 6 | D3 | input | Data input, loaded into the counter on the positive-going clock edge when PE is LOW. |
| 7 | CEP | input | Count enable input; both CEP and CET must be HIGH to count. |
| 8 | GND | power_in | Ground (0 V). |
| 9 | PE | input | Parallel enable input, active LOW; disables counting and loads D0 to D3 on the positive-going clock edge. |
| 10 | CET | input | Count enable carry input; must be HIGH to count and enables the terminal count output TC. |
| 11 | Q3 | output | Flip-flop output. |
| 12 | Q2 | output | Flip-flop output. |
| 13 | Q1 | output | Flip-flop output. |
| 14 | Q0 | output | Flip-flop output. |
| 15 | TC | output | Terminal count output; produces a HIGH pulse approximately equal in duration to a HIGH output of Q0. |
| 16 | VCC | power_in | Supply voltage. |
