Wuxi I core Elec · Flip Flops · SOP20
AIP74HC574SA20.TR from Wuxi I core Elec, in a SOP20. 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 input; a HIGH causes outputs Q0 to Q7 to assume the high-impedance OFF-state without changing the flip-flop contents. |
| 2 | D0 | input | Data input for flip-flop 0, sampled on the LOW-to-HIGH transition of CP and required to meet the set-up and hold times. |
| 3 | D1 | input | Data input for flip-flop 1, sampled on the LOW-to-HIGH transition of CP and required to meet the set-up and hold times. |
| 4 | D2 | input | Data input for flip-flop 2, sampled on the LOW-to-HIGH transition of CP and required to meet the set-up and hold times. |
| 5 | D3 | input | Data input for flip-flop 3, sampled on the LOW-to-HIGH transition of CP and required to meet the set-up and hold times. |
| 6 | D4 | input | Data input for flip-flop 4, sampled on the LOW-to-HIGH transition of CP and required to meet the set-up and hold times. |
| 7 | D5 | input | Data input for flip-flop 5, sampled on the LOW-to-HIGH transition of CP and required to meet the set-up and hold times. |
| 8 | D6 | input | Data input for flip-flop 6, sampled on the LOW-to-HIGH transition of CP and required to meet the set-up and hold times. |
| 9 | D7 | input | Data input for flip-flop 7, sampled on the LOW-to-HIGH transition of CP and required to meet the set-up and hold times. |
| 10 | GND | power_in | Ground (0 V) reference for all voltages. |
| 11 | CP | input | Clock input; the flip-flops store the state of their Dn inputs on the LOW-to-HIGH clock transition. |
| 12 | Q7 | tri_state | 3-state non-inverting flip-flop output 7, high-impedance when OE is HIGH. |
| 13 | Q6 | tri_state | 3-state non-inverting flip-flop output 6, high-impedance when OE is HIGH. |
| 14 | Q5 | tri_state | 3-state non-inverting flip-flop output 5, high-impedance when OE is HIGH. |
| 15 | Q4 | tri_state | 3-state non-inverting flip-flop output 4, high-impedance when OE is HIGH. |
| 16 | Q3 | tri_state | 3-state non-inverting flip-flop output 3, high-impedance when OE is HIGH. |
| 17 | Q2 | tri_state | 3-state non-inverting flip-flop output 2, high-impedance when OE is HIGH. |
| 18 | Q1 | tri_state | 3-state non-inverting flip-flop output 1, high-impedance when OE is HIGH. |
| 19 | Q0 | tri_state | 3-state non-inverting flip-flop output 0, high-impedance when OE is HIGH. |
| 20 | VCC | power_in | Supply voltage; recommended 2.0 V to 6.0 V for AiP74HC574 (4.5 V to 5.5 V for AiP74HCT574 variant). |
