It captures data on the positive edge of the clock (trigger type: positive edge) and presents non-inverted data at the outputs, which are tri-state controlled by an output-enable pin — letting multiple devices share a common bus without contention. ## 100 MHz clock — timing margin for synchronous buses Rated for a 100 MHz clock frequency, this register can latch data at 100 million transfers per second — suitable for address/data pipelines in 5 V CPLD glue logic, memory interfaces, or microcontroller bus expansion. The 8.5 ns maximum propagation delay at 5 V and 50 pF load (max propagation delay @ V, max CL) gives a tight but usable timing budget: at 100 MHz the clock period is 10 ns, leaving only 1.5 ns of setup-plus-hold margin after the clock-to-output delay. For designs that need more slack, the 74F374 sibling (also 8.5 ns at 5 V, 50 pF) offers the same delay but in a different pinout — verify the footprint before substituting. ## Output drive: 3 mA source, 24 mA sink The tri-state outputs can source 3 mA and sink 24 mA per pin (current - output high, low). The 24 mA sink capability is enough to drive a standard TTL input fan-out of 10 or more, or directly switch an LED through a series resistor. The 3 mA source side is weaker — keep that in mind if the output must drive a high-impedance bus with pull-up resistors; the rise time may be slower than the fall time. For heavily loaded backplanes, consider the 74F374 (same 24 mA sink) or a bus transceiver with symmetric drive. ## Package and footprint: 20-SOIC wide-body Housed in a 20-SOIC package with 0.295-inch body width (7.50 mm) — the wide SOIC variant. The supplier device package is 20-SOIC; the mounting type is surface mount. This is a standard JEDEC footprint shared by many 20-pin SOIC logic parts, so layout reuse across the 74F, 74LS, or 74ACT families is straightforward. The tube shipping medium (package: tube) is typical for through-hole and some SOIC logic; if your pick-and-place prefers tape-and-reel, order the 'R' suffix variant (SN74F574DWR) instead. ## Lifecycle and compliance: active, ROHS3, commercial temp It is ROHS3 compliant (rohs status: ROHS3), meeting current EU and global environmental requirements. The operating temperature range is 0°C to 70°C (operating temperature) — commercial grade, intended for indoor electronics, office equipment, appliances, and test gear. Not rated for industrial or automotive environments; for those, look at the 74FCT or 74ABT families with extended temperature options. ## Sourcing reality for the BOM line This is a current-production, widely stocked logic part. For a BOM line that needs a high-speed 8-bit register with tri-state outputs in a 5 V system, the SN74F574DW is a straightforward fit. No single-source risk; Texas Instruments has multiple fabs running the 74F process, and the 20-SOIC package is a standard commodity footprint.","metaTitle":"SN74F574DW 74F D-Type Flip-Flop, 100 MHz, 20-SOIC","metaDescription":"TI SN74F574DW 8-bit D-type flip-flop with tri-state outputs. 100 MHz clock, 8.5 ns prop delay at 5V.
