It runs on a 4.5V to 5.5V supply and clocks at 80 MHz, making it a drop-in for 5V TTL/CMOS bus-interface and register applications where you need six bits of storage with a clean reset line. The 24 mA source and sink drive per output gives it the fan-out to drive multiple CMOS loads or a short backplane trace without a buffer. ## Military temperature range — the deployment envelope Rated for -55°C to 125°C ambient, this part is specced for environments where commercial or even industrial grade parts won't hold — avionics bay, satellite payload, downhole instrumentation, or outdoor telecom cabinets that see the full diurnal swing. The 80 MHz clock rate holds across that range, though the propagation delay of 14 ns at 5V and 50 pF load is the figure to budget for timing closure at the cold end, where CMOS switching slows slightly. ## Supply rail and quiescent draw The 4.5V to 5.5V supply range means this part lives on a regulated 5V rail — not 3.3V or 1.8V logic. Quiescent current is 8 µA typical, negligible for the power budget, but the dynamic draw scales with the 80 MHz clock and the 24 mA output switching load. Input capacitance is 10 pF per pin, which matters for the driving gate's rise-time budget when clocking at full speed. ## Package and footprint — 16-SOIC narrow-body Housed in a 16-SOIC narrow-body (3.90 mm width) package, surface-mount only. The 0.154-inch body width is the standard SOIC-16 footprint — no surprises for the PCB layout. The supplier device package is 16-SOIC, and the shipping medium is tube, not tape-and-reel; if your pick-and-place line expects reel feed, factor in the tube-to-reel transfer or source the tape-and-reel variant. ## Lifecycle and compliance — active, no end-of-life signal ROHS3 compliant, so it passes the EU material restrictions without an exemption. For a BOM line that needs a qualified second source, the 74ACT family has multiple suppliers (TI, Nexperia, others) producing functionally identical parts, though the exact CD74ACT174M marking is TI-specific. Qualifying a cross from a second manufacturer now avoids a single-source lock-in later.","metaTitle":"CD74ACT174M D-Type Flip-Flop, 80 MHz, 16-SOIC, -55 to 125°C","metaDescription":"CD74ACT174M 74ACT series D-type flip-flop, 80 MHz clock, 24 mA output, 4.5-5.5V supply, -55 to 125°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":"74ACT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"D-Type","Series":"74ACT","Package":"Tube","Function":"Master Reset","Output Type":"Non-Inverted","Trigger Type":"Positive Edge","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","Clock Frequency":"80 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Input Capacitance":"10 pF","Number of Elements":"1","Operating Temperature":"-55°C ~ 125°C (TA)","Supplier Device Package":"16-SOIC","Current - Quiescent (Iq)":"8 µA","Current - Output High, Low":"24mA, 24mA","Number of Bits per Element":"6","Max Propagation Delay @ V, Max CL":"14ns @ 5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.62","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.62000","currency":"USD"},{"qty":10,"price":"$1.44800","currency":"USD"},{"qty":25,"price":"$1.37400","currency":"USD"},{"qty":100,"price":"$1.12880","currency":"USD"},{"qty":250,"price":"$1.05516","currency":"USD"},{"qty":500,"price":"$0.93248","currency":"USD"},{"qty":1000,"price":"$0.73617","currency":"USD"},{"qty":2500,"price":"$0.69450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5e0d815fbf31ae019b00ce50f95ea6ca.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can CD74ACT174M replace 74LS174?","answer":"Both are 6-bit positive-edge D-type flip-flops with master reset and non-inverted outputs, so the function matches. The CD74ACT174M runs at 80 MHz versus the 74LS174's typical 40 MHz, and the 74ACT family uses CMOS technology with lower quiescent current (8 µA vs roughly 22 mA for LS). The 74LS174 operates from 4.75V to 5.25V and has a 27 ns propagation delay at 5V and 15 pF, while the ACT174 has 14 ns at 5V and 50 pF.

The key difference is the logic family: 74ACT is designed for 5V TTL-compatible input thresholds (TTL levels) while 74HC uses CMOS thresholds (30%/70% of Vcc). At 5V supply, the ACT174 switches at lower input voltages (0.8V max low, 2.0V min high) which makes it directly compatible with older TTL logic outputs. The HC174 needs rail-to-rail CMOS drive. Clock speed and output drive also differ — the ACT174 is rated for 80 MHz and 24 mA output, while typical HC174 parts run at about 50 MHz and 4 mA output.
