8-bit D-Type in 20-SOIC, 140 MHz edge rate
The 74F374SCX-NS is an 8-bit D-type flip-flop from Texas Instruments' 74F series, packaged in a 20-SOIC (7.50 mm width) for surface-mount assembly. It captures data on the positive edge of the clock and presents it at tri-state, non-inverted outputs — a standard register function for bus-oriented memory and control logic. Clock frequency reaches 140 MHz, with a maximum propagation delay of 8.5 ns at 5 V into a 50 pF load. Supply range is 4.5 V to 5.5 V, and quiescent current sits at 86 mA — the 74F family trades higher static draw for faster edge rates compared to the 74LS or 74HC siblings.
Output drive and temperature grade
Output high current is rated 24 mA, output low at 3 mA — the asymmetric drive reflects the totem-pole stage's sourcing vs sinking capability. Operating temperature covers 0°C to 70°C ambient, the commercial range suitable for indoor equipment and bench-level instrumentation. The 20-SOIC footprint (0.295-inch body width) is a common JEDEC outline; the supplier device package is listed as 20-SOIC. Bulk packaging means the parts ship in tubes or trays, not tape-and-reel — factor this into pick-and-place feeder setup if the line expects reels.
Active production, RoHS non-compliant
RoHS compliance status is marked as non-compliant. The 74F series predates the RoHS directive; the lead-bearing finish is acceptable for military, aerospace, and legacy repair applications where lead-free exemption applies, but it may not pass a RoHS-10 screening for new consumer or medical designs.
Cross-reference to 74F174PC
The 74F374SCX-NS offers 8 bits vs 6, surface-mount vs through-hole, and lacks the reset pin. A board designed for the 74F174PC would need a layout change to accept the 74F374SCX-NS.
