SN74LVC74ADBR

Texas Instruments · Flip Flops · SSOP-14-208mil

SN74LVC74ADBR from Texas Instruments, in a SSOP-14-208mil. 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 Channel 1 clear input; driving it low forces the 1Q output low (active-low asynchronous clear).
2 1D input Channel 1 data input, sampled on the rising edge of 1CLK.
3 1CLK input Channel 1 clock input; the flip-flop is positive-edge triggered.
4 1PRE input Channel 1 preset input; driving it low forces the 1Q output high (active-low asynchronous preset).
5 1Q output Channel 1 true output.
6 ~{1Q} output Channel 1 complementary (inverted) output.
7 GND power_in Ground reference pin.
8 ~{2Q} output Channel 2 complementary (inverted) output.
9 2Q output Channel 2 true output.
10 2PRE input Channel 2 preset input; driving it low forces the 2Q output high (active-low asynchronous preset).
11 2CLK input Channel 2 clock input; the flip-flop is positive-edge triggered.
12 2D input Channel 2 data input, sampled on the rising edge of 2CLK.
13 2CLR input Channel 2 clear input; driving it low forces the 2Q output low (active-low asynchronous clear).
14 VCC power_in Supply voltage; SN74LVC74A operates from 1.65 V to 3.6 V, and each VCC terminal should have a good bypass capacitor (0.1 µF recommended for single-supply devices).
