The tri-state, non-inverted outputs let multiple registers share a common data bus — the output enable control puts the outputs into high-impedance state when deasserted, avoiding bus contention in multiplexed systems. Clock frequency reaches 60 MHz, with a maximum propagation delay of 34 ns at 6 V supply into a 50 pF load. The 2 V to 6 V supply range covers both 3.3 V and 5 V logic rails, and the -55°C to 125°C operating temperature range suits industrial or extended-temperature environments. ## Package, power, and output drive for board integration Housed in a 16-pin DIP (0.300-inch body, 7.62 mm pitch) with through-hole mounting — the 16-PDIP supplier package footprint is standard for breadboard prototyping and legacy PCB layouts. The tube packaging keeps the leads aligned during handling and storage. Quiescent current is just 8 µA, making this a low-static-power choice for battery-backed or always-on logic sections. Output drive capability is 7.8 mA per pin for both source and sink, enough to drive standard TTL loads or LED indicators through a series resistor. Input capacitance is 10 pF per input, a typical 74HC figure that keeps the clock line loading predictable.","metaTitle":"CD74HC173E Texas Instruments 74HC D-Type Flip-Flop, 60 MHz","metaDescription":"CD74HC173E D-Type flip-flop, 4-bit, tri-state output, 60 MHz clock, 2-6 V supply, -55 to 125°C.
