Frequently Asked Questions
How do I operate this flip-flop in D-type mode?
The J and K inputs must be tied together to allow operation as a D-type flip-flop by connecting them (J=K).
What is the maximum clock frequency of the 74HC/HCT109?
The device supports a maximum clock frequency ($f$) of 75 MHz.
Can I use this component in life support applications?
No, these products are not designed for use in life support appliances, devices, or systems where malfunction is expected to result in personal injury.
What defines the power supply limitations between HC and HCT variants?
For HC, $V_{CC}$ ranges from GND to $V_{CC}$, while for HCT it requires a range of GND to $V_{CC} - 1.5$ V.
Are there specific precautions needed during soldering or reflowing?
The contact pressure-syringe dispensing time must be limited to 10 seconds at up to 300°C when soldering the component.
