SN74HC74QPWRG4Q1

Texas Instruments · Flip Flops · TSSOP-14

SN74HC74QPWRG4Q1 from Texas Instruments, in a TSSOP-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 Channel 1 clear input, active low; driving it low forces Q low and Q̄ high while PRE is high.
2 1D input Channel 1 data input, which is transferred to Q on the positive edge of 1CLK when PRE and CLR are inactive.
3 1CLK input Channel 1 positive-edge-triggered clock input.
4 1PRE input Channel 1 preset input, active low; driving it low forces Q high and Q̄ low while CLR is high.
5 1Q output Channel 1 true output.
6 1Q̄ output Channel 1 inverted output.
7 GND power_in Ground reference for the device.
8 2Q̄ output Channel 2 inverted output.
9 2Q output Channel 2 true output.
10 2PRE input Channel 2 preset input, active low; driving it low forces Q high and Q̄ low while CLR is high.
11 2CLK input Channel 2 positive-edge-triggered clock input.
12 2D input Channel 2 data input, which is transferred to Q on the positive edge of 2CLK when PRE and CLR are inactive.
13 2CLR input Channel 2 clear input, active low; driving it low forces Q low and Q̄ high while PRE is high.
14 VCC power_in Positive supply; recommended operating range is 2 V to 6 V, with an absolute maximum of 7 V.
