SN74LVC74AMDREP

Texas Instruments · Flip Flops · SOIC-14

SN74LVC74AMDREP from Texas Instruments, in a SOIC-14. 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 1CLR input Active-low asynchronous clear for flip-flop 1; a low level resets the outputs regardless of the other inputs.
2 1D input Data input for flip-flop 1, transferred to the outputs on the positive-going clock edge (setup 3.4 ns min at 3.3 V ± 0.3 V).
3 1CLK input Positive-edge clock input for flip-flop 1; triggering occurs at a voltage level and is not directly related to the clock rise time.
4 1PRE input Active-low asynchronous preset for flip-flop 1; a low level sets the outputs regardless of the other inputs.
5 1Q output True output of flip-flop 1, rated for 24 mA at VCC = 3 V.
6 1Q̅ output Complementary output of flip-flop 1, rated for 24 mA at VCC = 3 V.
7 GND power_in Ground; continuous current through VCC or GND is limited to ±100 mA.
8 2Q̅ output Complementary output of flip-flop 2, rated for 24 mA at VCC = 3 V.
9 2Q output True output of flip-flop 2, rated for 24 mA at VCC = 3 V.
10 2PRE input Active-low asynchronous preset for flip-flop 2; a low level sets the outputs regardless of the other inputs.
11 2CLK input Positive-edge clock input for flip-flop 2; triggering occurs at a voltage level and is not directly related to the clock rise time.
12 2D input Data input for flip-flop 2, transferred to the outputs on the positive-going clock edge (setup 3.4 ns min at 3.3 V ± 0.3 V).
13 2CLR input Active-low asynchronous clear for flip-flop 2; a low level resets the outputs regardless of the other inputs.
14 VCC power_in Supply voltage, operating range 2 V to 3.6 V (absolute maximum 6.5 V).
