Dual D-type flip-flop in a through-hole DIP
Each of the two elements stores one bit, clocked up to 150 MHz. The 14-pin DIP package is a through-hole part, so it sits on a breadboard or a production board with 0.300-inch row spacing — no reflow profile needed, just a clean wave or hand-solder joint.
Supply range and drive capability
Supply voltage spans 3 V to 5.5 V. Quiescent current is 4 µA.
150 MHz clock — timing margin for fast counters
Maximum clock frequency is 150 MHz. Propagation delay is 7.5 ns at 5 V, 50 pF.
It fits outdoor telecom cabinets, factory-floor PLC I/O modules, and engine-bay-adjacent electronics that see thermal cycling but not continuous under-hood heat. The 14-PDIP package has a modest thermal mass — no heatsinking needed, but keep it away from high-power resistors or regulators on the same board if ambient runs near the upper limit.
