Texas Instruments · Flip Flops · SOIC-20-300mil
CD74ACT574M96 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 output enable; when HIGH, the 3-state outputs go to the high-impedance state independent of the register operation. |
| 2 | 1Q | output | Non-inverted data output of flip-flop 1, high-impedance when OE is HIGH. |
| 3 | 1D | input | Data input to flip-flop 1, loaded into the register on the LOW-to-HIGH transition of CLK. |
| 4 | 2D | input | Data input to flip-flop 2, loaded into the register on the LOW-to-HIGH transition of CLK. |
| 5 | 2Q | output | Non-inverted data output of flip-flop 2, high-impedance when OE is HIGH. |
| 6 | 3Q | output | Non-inverted data output of flip-flop 3, high-impedance when OE is HIGH. |
| 7 | 3D | input | Data input to flip-flop 3, loaded into the register on the LOW-to-HIGH transition of CLK. |
| 8 | 4D | input | Data input to flip-flop 4, loaded into the register on the LOW-to-HIGH transition of CLK. |
| 9 | 4Q | output | Non-inverted data output of flip-flop 4, high-impedance when OE is HIGH. |
| 10 | GND | power_in | Ground pin; all voltages are referenced to ground. |
| 11 | CLK | input | Clock input; the eight flip-flops capture data on the LOW-to-HIGH transition of CLK. |
| 12 | 5Q | output | Non-inverted data output of flip-flop 5, high-impedance when OE is HIGH. |
| 13 | 5D | input | Data input to flip-flop 5, loaded into the register on the LOW-to-HIGH transition of CLK. |
| 14 | 6D | input | Data input to flip-flop 6, loaded into the register on the LOW-to-HIGH transition of CLK. |
| 15 | 6Q | output | Non-inverted data output of flip-flop 6, high-impedance when OE is HIGH. |
| 16 | 7Q | output | Non-inverted data output of flip-flop 7, high-impedance when OE is HIGH. |
| 17 | 7D | input | Data input to flip-flop 7, loaded into the register on the LOW-to-HIGH transition of CLK. |
| 18 | 8D | input | Data input to flip-flop 8, loaded into the register on the LOW-to-HIGH transition of CLK. |
| 19 | 8Q | output | Non-inverted data output of flip-flop 8, high-impedance when OE is HIGH. |
| 20 | VCC | power_in | Supply pin; ACT types are specified for 4.5 V to 5.5 V (recommended operating conditions). |
