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.

The key difference is package: the CD74ACT574E comes in a 20-PDIP (through-hole, 0.300\" wide), while the SN74ACT574 is typically offered in a surface-mount SOIC or SSOP package. The CD variant also carries the full military temperature range (-55°C to 125°C) versus the industrial range of many SN74ACT574 variants.
