Logic family and supply-voltage flexibility
The CD74AC573E is a single D-type transparent latch from the 74AC family, with eight latches per package and a tri-state output bus.
Temperature grade and propagation delay
Rated for -55°C to +125°C, this latch covers the full military temperature band — suitable for avionics, downhole instrumentation, or engine-bay control modules where the ambient exceeds the commercial 85°C ceiling. The 3 ns typical propagation delay means the data path settles within one clock cycle at 100+ MHz bus speeds, provided the trace length and load capacitance are managed.
Output drive and package
The 20-pin PDIP package (0.300" body width) is a through-hole footprint that breadboards easily and survives repeated rework — a practical choice for prototyping or legacy board spins where a SOIC would require a layout change.
