The operating characteristics mention here apply to all flip-flops regardless of the particular form of the circuit. They are typically found in data sheets for integrated circuits. They specify the performance, operating requirements, and operating limitations of the circuit.
Propagation Delay Time - is the interval of time required after an input signal has been applied for the resulting output change to occur.Set-Up Time - is the minimum interval required for the logic levels to be maintained constantly on the inputs (J and K, or S and R, or D) prior to the triggering edge of the clock pulse in order for the levels to be reliably clocked into the flip-flop.
Hold Time - is the minimum interval required for the logic levels to remain on the inputs after the triggering edge of the clock pulse in order for the levels to be reliably clocked into the flip-flop.
Maximum Clock Frequency - is the highest rate that a flip-flop can be reliably triggered.
Power Dissipation - is the total power consumption of the device.
Pulse Widths - are the minimum pulse widths specified by the manufacturer for the Clock, SET and CLEAR inputs.
