In a typical digital system, it captures the data bus state on each rising clock edge and holds it until the next edge, making it the register element in a pipeline or a parallel-output port. ## Clock speed and propagation delay Rated clock frequency of 125 MHz sets the maximum toggle rate for the register bank — above this the internal setup/hold margins collapse. The propagation delay is 10.8 ns max at 5 V into a 50 pF load, meaning the data at the output pins is valid 10.8 ns after the clock edge; this defines the timing budget for the downstream logic. ## Package and through-hole integration Supplied in a 20-pin PDIP (0.300-inch, 7.62 mm body width) — the through-hole footprint is breadboard- and socket-friendly, and the 0.100-inch pitch mates with standard wire-wrap or IDC headers. The tube packaging keeps the leads aligned for automated insertion or hand assembly.","metaTitle":"CD74AC374E Texas Instruments 74AC D-Type Flip-Flop, 125 MHz","metaDescription":"CD74AC374E D-Type flip-flop, 8-bit, 125 MHz clock, 1.5V-5.5V supply, -55°C to 125°C.
