# CD74HCT74M96

**Texas Instruments** · Flip Flops · SOIC-14

CD74HCT74M96 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 | Channel 1 clear input, active low; a low level forces 1Q low and 1Q̄ high, independent of the clock. |
| 2 | 1D | input | Channel 1 data input, transferred to the outputs on the positive edge of 1CLK and subject to setup and hold times. |
| 3 | 1CLK | input | Channel 1 positive-edge-triggered clock input. |
| 4 | 1PRE | input | Channel 1 preset input, active low; a low level forces 1Q high and 1Q̄ low, independent of the clock. |
| 5 | 1Q | output | Channel 1 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 output. |
| 10 | 2PRE | input | Channel 2 preset input, active low; a low level forces 2Q high and 2Q̄ low, independent of the clock. |
| 11 | 2CLK | input | Channel 2 positive-edge-triggered clock input. |
| 12 | 2D | input | Channel 2 data input, transferred to the outputs on the positive edge of 2CLK and subject to setup and hold times. |
| 13 | 2CLR | input | Channel 2 clear input, active low; a low level forces 2Q low and 2Q̄ high, independent of the clock. |
| 14 | VCC | power_in | Positive supply; recommended operating range 4.5 V to 5.5 V, absolute maximum 7 V. |
