CD74AC163M96 from Texas Instruments, in a SOIC-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 | Synchronous clear input; a low level sets all four flip-flop outputs low after the next low-to-high transition of CLK. |
| 2 | CLK | input | Buffered clock input; triggers the four flip-flops on the rising (positive-going) edge of the clock waveform. |
| 3 | A | input | Parallel load/preset data input A; one of four inputs for presetting the counter to any number between 0 and 15. |
| 4 | B | input | Parallel load/preset data input B; one of four inputs for presetting the counter to any number between 0 and 15. |
| 5 | C | input | Parallel load/preset data input C; one of four inputs for presetting the counter to any number between 0 and 15. |
| 6 | D | input | Parallel load/preset data input D; one of four inputs for presetting the counter to any number between 0 and 15. |
| 7 | ENP | input | Count enable input (Enable P); both ENP and ENT must be high to enable counting. |
| 8 | GND | power_in | Ground; power return. |
| 9 | LOAD | input | Synchronous parallel load input; a low level disables the counter and causes outputs to agree with setup data after the next clock pulse. |
| 10 | ENT | input | Count enable input (Enable T/ripple carry enable); both ENP and ENT must be high to count; fed forward to enable RCO. |
| 11 | QD | output | Output QD; binary counter output D, the Q output of the D/T flip-flop for bit D. |
| 12 | QC | output | Output QC; binary counter output C, the Q output of the D/T flip-flop for bit C. |
| 13 | QB | output | Output QB; binary counter output B, the Q output of the D/T flip-flop for bit B. |
| 14 | QA | output | Output QA; binary counter output A, the Q output of the D/T flip-flop for bit A. |
| 15 | RCO | output | Ripple carry output; produces a high-level pulse while the count is at maximum (9 or 15 with QA high) and ENT is high, for cascading counters. |
| 16 | VCC | power_in | Positive supply voltage; operating range 1.5 V to 5.5 V. |
