Nexperia · Flip Flops · SOIC-20-300mil

74LVC574AD from Nexperia, 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 Output enable input, active LOW; a HIGH puts the outputs in the high-impedance OFF-state without affecting the flip-flop state.
2 D0 input Data input 0, stored on the LOW-to-HIGH clock transition; tolerant to 5.5 V.
3 D1 input Data input 1, stored on the LOW-to-HIGH clock transition; tolerant to 5.5 V.
4 D2 input Data input 2, stored on the LOW-to-HIGH clock transition; tolerant to 5.5 V.
5 D3 input Data input 3, stored on the LOW-to-HIGH clock transition; tolerant to 5.5 V.
6 D4 input Data input 4, stored on the LOW-to-HIGH clock transition; tolerant to 5.5 V.
7 D5 input Data input 5, stored on the LOW-to-HIGH clock transition; tolerant to 5.5 V.
8 D6 input Data input 6, stored on the LOW-to-HIGH clock transition; tolerant to 5.5 V.
9 D7 input Data input 7, stored on the LOW-to-HIGH clock transition; tolerant to 5.5 V.
10 GND power_in Ground (0 V).
11 CP input Clock input, LOW-to-HIGH edge triggered.
12 Q7 tri_state 3-state data output 7, high-impedance when OE is HIGH.
13 Q6 tri_state 3-state data output 6, high-impedance when OE is HIGH.
14 Q5 tri_state 3-state data output 5, high-impedance when OE is HIGH.
15 Q4 tri_state 3-state data output 4, high-impedance when OE is HIGH.
16 Q3 tri_state 3-state data output 3, high-impedance when OE is HIGH.
17 Q2 tri_state 3-state data output 2, high-impedance when OE is HIGH.
18 Q1 tri_state 3-state data output 1, high-impedance when OE is HIGH.
19 Q0 tri_state 3-state data output 0, high-impedance when OE is HIGH.
20 VCC power_in Supply voltage, 1.65 V to 3.6 V recommended (functional down to 1.2 V).
