Clock rate and propagation delay — the timing budget
The 110 MHz maximum clock frequency sets the upper bound for synchronous operation. In practice, the 11.2 ns propagation delay at 5V with a 50 pF load is the number you use for setup-time analysis.
Temperature range and package — where it fits
The -55°C to 125°C operating range qualifies this flip-flop for avionics, satellite, downhole drilling, and military ground-vehicle electronics. The 20-PDIP package is through-hole, which simplifies prototyping and rework in high-reliability assemblies.
Lifecycle and sourcing reality
No end-of-life notice or last-time-buy is indicated. For a BOM line that requires a through-hole 8-bit register with military temperature range, this part is a current, manufacturable choice.
