CD74ACT161M96 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 | Asynchronous clear input; low level sets all four flip-flop outputs low regardless of other inputs. |
| 2 | CLK | input | Buffered clock input; triggers the four flip-flops on the rising edge of the clock waveform. |
| 3 | A | input | Preset data input A; defines the preset value for output bit A when LOAD is low. |
| 4 | B | input | Preset data input B; defines the preset value for output bit B when LOAD is low. |
| 5 | C | input | Preset data input C; defines the preset value for output bit C when LOAD is low. |
| 6 | D | input | Preset data input D; defines the preset value for output bit D when LOAD is low. |
| 7 | ENP | input | Parallel count enable input; counter counts only when both ENP and ENT are high. |
| 8 | GND | power_in | Ground; 0 V reference voltage. |
| 9 | LOAD | input | Load input; low level synchronously presets counter outputs to match preset data inputs on next clock pulse. |
| 10 | ENT | input | Terminal count enable input; counter counts when both ENP and ENT are high; fed forward to enable RCO. |
| 11 | QD | output | 4-bit binary counter output bit D (most significant bit). |
| 12 | QC | output | 4-bit binary counter output bit C. |
| 13 | QB | output | 4-bit binary counter output bit B. |
| 14 | QA | output | 4-bit binary counter output bit A (least significant bit). |
| 15 | RCO | output | Ripple-carry output; produces high-level pulse when counter reaches terminal count (maximum value) and ENT is high. |
| 16 | VCC | power_in | Positive supply voltage; 4.5 V to 5.5 V recommended operating range. |
