What the 3V to 18V supply range means for your BOM
The Texas Instruments CD40174BPW is a 4000B-series D-type flip-flop that packs six positive-edge-triggered, non-inverted outputs with a master reset function into a 16-TSSOP package. Its 3V to 18V supply range is the defining feature — it lets you run the same logic rail as a 5V microcontroller, a 12V industrial sensor bus, or a 9V battery without a secondary regulator. The 16 MHz clock ceiling and 100 ns propagation delay (at 15V, 50 pF) are adequate for slow-to-moderate-speed control and status-latching tasks where 74LS or 74F parts would need a tighter 5V supply.
The 4 µA quiescent current keeps the power budget lean even at temperature extremes.
The 16-TSSOP body (4.40 mm width, 0.173" pitch) is a surface-mount footprint shared across many 4000B and HCMOS logic functions. If you're replacing a through-hole CD40174BE, the PW suffix signals the TSSOP variant — you'll need a board respin to accommodate the smaller land pattern.
