That puts it in the fast lane of the 5V logic families — well ahead of the 74LS series (40 MHz, 25ns) and competitive with 74F (80 MHz, 10ns). It is a single-element, 4-bit positive-edge-triggered register with complementary outputs and an asynchronous master reset. The 4.75V to 5.25V supply range matches legacy 5V TTL rails, and the 96 mA quiescent current reflects the Schottky-clamped speed advantage. ## Master reset and complementary outputs — the logic interface The master reset input (active low, per the function) clears all four flip-flops asynchronously, which is useful for power-on initialization or emergency reset without waiting for a clock edge. Complementary outputs give you both Q and /Q on each bit — handy for differential data paths or driving paired logic without external inverters. The output drive capability is 1 mA sourcing and 20 mA sinking, typical for Schottky TTL and sufficient for driving one or two standard TTL loads or a CMOS input with a pull-up. If your design lives in an unconditioned enclosure or sees ambient above 70°C, you will need to budget for airflow or move to an extended-temperature logic family. It is ROHS3 compliant.","metaTitle":"SN74S175D D-Type Flip-Flop, 110 MHz, 16-SOIC","metaDescription":"Texas Instruments SN74S175D 74S D-type flip-flop, 110 MHz clock, 12ns propagation delay, 4.75-5.25V supply, 16-SOIC.","metaKeywords":null},"attributes":{"series":"74S","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"D-Type","Series":"74S","Package":"Tube","Function":"Master Reset","Output Type":"Complementary","Trigger Type":"Positive Edge","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","Clock Frequency":"110 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Number of Elements":"1","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"16-SOIC","Current - Quiescent (Iq)":"96 mA","Current - Output High, Low":"1mA, 20mA","Number of Bits per Element":"4","Max Propagation Delay @ V, Max CL":"12ns @ 5V, 15pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.89","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.89000","currency":"USD"},{"qty":10,"price":"$2.59600","currency":"USD"},{"qty":25,"price":"$2.44880","currency":"USD"},{"qty":100,"price":"$2.08620","currency":"USD"},{"qty":250,"price":"$1.95888","currency":"USD"},{"qty":500,"price":"$1.71402","currency":"USD"},{"qty":1000,"price":"$1.42019","currency":"USD"},{"qty":2500,"price":"$1.38600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/482677d37a5910a3089d31e789224f96.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will SN74S175D drop into a board originally built with SN74LS175NS?","answer":"Functionally yes — both are 4-bit D-type flip-flops with positive-edge trigger, complementary outputs, and master reset, in a 16-pin SOIC footprint. The key difference is speed: the 74S part clocks at 110 MHz with 12ns propagation delay, versus 40 MHz and 25ns for the 74LS. The 74S also draws roughly 5x the quiescent current (96 mA vs ~18 mA). If the original board was designed for the slower 74LS timing, the SN74S175D will work, but the higher supply current may exceed the existing power budget. Verify the 5V rail can deliver the extra current before substituting."},{"question":"What compliance documentation does TI provide for SN74S175D?","answer":"The part is ROHS3 compliant.
