CD74ACT574M96

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).
