SN74LV163APWR from Texas Instruments, in a TSSOP-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 | CLR | input | Clear input, active low, resets all counter outputs |
| 2 | CLK | input | Clock input, rising edge triggered for synchronous counting |
| 3 | A | input | Parallel load data input A |
| 4 | B | input | Parallel load data input B |
| 5 | C | input | Parallel load data input C |
| 6 | D | input | Parallel load data input D |
| 7 | ENP | input | Count enable input that does not affect the ripple-carry output |
| 8 | GND | power_in | Ground, 0V reference |
| 9 | LOAD | input | Parallel load control input, active low |
| 10 | ENT | input | Count enable input that affects the ripple-carry output |
| 11 | QD | output | Counter output bit D |
| 12 | QC | output | Counter output bit C |
| 13 | QB | output | Counter output bit B |
| 14 | QA | output | Counter output bit A |
| 15 | RCO | output | Ripple-carry output for cascading counters |
| 16 | VCC | power_in | Supply voltage with operating range 2V to 5.5V |
