The CD4019BM96 can handle clock frequencies up to 10 MHz.
The CD4019BM96 requires a single 5V power supply, and it's recommended to use a decoupling capacitor (e.g., 0.1uF) between VCC and GND to reduce noise and ensure stable operation.
Yes, the CD4019BM96 can be used as a simple inverter or buffer by connecting the input to the output through a resistor, and using the remaining gates as inverters or buffers.
You can implement a flip-flop using the CD4019BM96 by connecting two gates in a feedback loop, with the output of one gate connected to the input of the other, and using the remaining gates as inputs or outputs.
While the CD4019BM96 can handle clock frequencies up to 10 MHz, it's not suitable for very high-speed applications (e.g., above 50 MHz) due to its propagation delay and rise/fall times.
