CD74HC574M96 from Texas Instruments, in a SOIC-20-300mil. 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 | OE | input | Active-LOW 3-state output enable; when HIGH all Q outputs enter high-impedance state, independent of CP or D inputs. |
| 2 | D0 | input | Data input 0; logic level is captured into the flip-flop on the LOW-to-HIGH transition of CP. |
| 3 | D1 | input | Data input 1; logic level is captured into the flip-flop on the LOW-to-HIGH transition of CP. |
| 4 | D2 | input | Data input 2; logic level is captured into the flip-flop on the LOW-to-HIGH transition of CP. |
| 5 | D3 | input | Data input 3; logic level is captured into the flip-flop on the LOW-to-HIGH transition of CP. |
| 6 | D4 | input | Data input 4; logic level is captured into the flip-flop on the LOW-to-HIGH transition of CP. |
| 7 | D5 | input | Data input 5; logic level is captured into the flip-flop on the LOW-to-HIGH transition of CP. |
| 8 | D6 | input | Data input 6; logic level is captured into the flip-flop on the LOW-to-HIGH transition of CP. |
| 9 | D7 | input | Data input 7; logic level is captured into the flip-flop on the LOW-to-HIGH transition of CP. |
| 10 | GND | power_in | Ground supply reference; continuous current through GND pin not to exceed ±50 mA. |
| 11 | CP | input | Clock input; all eight flip-flops capture their D inputs on the LOW-to-HIGH transition; maximum clock frequency 30 MHz (typ) at VCC = 4.5 V. |
| 12 | Q7 | tri_state | 3-state registered output 7; capable of driving 15 LSTTL loads; enters high-impedance state when OE is HIGH. |
| 13 | Q6 | tri_state | 3-state registered output 6; capable of driving 15 LSTTL loads; enters high-impedance state when OE is HIGH. |
| 14 | Q5 | tri_state | 3-state registered output 5; capable of driving 15 LSTTL loads; enters high-impedance state when OE is HIGH. |
| 15 | Q4 | tri_state | 3-state registered output 4; capable of driving 15 LSTTL loads; enters high-impedance state when OE is HIGH. |
| 16 | Q3 | tri_state | 3-state registered output 3; capable of driving 15 LSTTL loads; enters high-impedance state when OE is HIGH. |
| 17 | Q2 | tri_state | 3-state registered output 2; capable of driving 15 LSTTL loads; enters high-impedance state when OE is HIGH. |
| 18 | Q1 | tri_state | 3-state registered output 1; capable of driving 15 LSTTL loads; enters high-impedance state when OE is HIGH. |
| 19 | Q0 | tri_state | 3-state registered output 0; capable of driving 15 LSTTL loads; enters high-impedance state when OE is HIGH. |
| 20 | VCC | power_in | Positive supply voltage; HC type: 2 V to 6 V; continuous current not to exceed ±50 mA; decouple with 0.1 µF close to pin. |
