Here's a summary of the key parameters from the provided datasheet excerpts for the 74LVC1G79 single D-type flip-flop, organized for clarity. I've presented the ranges as the voltage varies (1.65-1.95V, 2.3-2.7V, 2.7V, 3.0-3.6V, and 4.5-5.5V). Where values remain constant across ranges, I've noted that.

1. Static Characteristics (Not present in the provided snippets, but important for completeness - assuming typical values):

️· VCC Range: 1.65V to 5.5V (This is implied by the parameter ranges provided)

2. Timing Characteristics (Propagation delays, setup, hold, pulse width, and maximum frequency):

| Parameter | 1.65-1.95V | 2.3-2.7V | 2.7V | 3.0-3.6V | 4.5-5.5V |
| :----------------------- | :------------- | :------------- | :------- | :------------- | :------------- |
| tPHL/tPLH (Propagation Delay) | 1.0ns-12.5ns | 0.5ns-9.0ns | 0.5ns-8.0ns| 0.5ns-6.5ns | 0.5ns-5.0ns |
| tsu (Setup Time) | 2.5ns | 1.7ns | 1.7ns | 1.2ns | 1.2ns |
| th (Hold Time) | 0ns | 0ns | 0.5ns | 0.5ns | 0.5ns |
| tW (Clock Pulse Width) | 3.0ns | 2.5ns | 2.5ns | 2.5ns | 2.0ns |
| fmax (Max Clock Frequency) | 160MHz | 160MHz | 160MHz | 160MHz | 200MHz |

Key Observations:

️· Voltage Dependence: Generally, as the supply voltage (VCC) *increases*, the propagation delay (tPHL/tPLH) *decreases*, and the maximum clock frequency (fmax) *increases*. This is expected behavior for CMOS logic.
️· Setup and Hold Times: These are critical for reliable operation. The input data must be stable *before* the clock edge (setup time) and remain stable *after* the clock edge (hold time).

️· Clock Pulse Width: The clock signal must be high or low for at least this duration.
️· Typical Values: The datasheet notes typical values are measured at Tamb = 25°C.

Important Considerations:

️· Datasheet is Incomplete: This summary is based on the *excerpts* you provided. A full datasheet would contain additional critical parameters (e.g., input/output characteristics, power consumption, etc.).
️· Operating Conditions: The values above are only valid within the specified operating conditions (voltage, temperature, etc.).
