The reset function overrides the clock and sets the outputs to a known state. Rated for a clock frequency up to 56 MHz, the part suits moderate-speed logic chains in through-hole designs where a 5 V rail is already present. ## Temperature grade and output drive This makes it viable for avionics bay, engine test cell, or outdoor telecom enclosures where the ambient swings well beyond commercial 0-70°C limits. Each output sinks or sources 4 mA (at Vcc = 4.5 V), which is typical for HCT family gates. The 4 mA drive directly interfaces with standard CMOS inputs and most TTL loads without a buffer stage. Propagation delay is 43 ns maximum at 4.5 V with a 50 pF load — this sets the timing budget for cascaded stages: two flip-flops in series add 86 ns of clock-to-output latency before the next logic decision. Quiescent current is 4 µA typical, so the part adds negligible static draw to the supply rail. Input capacitance is 10 pF per input, which matters for clock line loading when multiple flip-flops share a common clock trace. ## Package and board-fit Housed in a 14-pin PDIP (0.300-inch, 7.62 mm body width), the CD74HCT107E is a through-hole part that mounts directly into a standard 0.100-inch pitch DIP socket or solders into plated through-holes on a 2.54 mm grid. The 14-PDIP footprint is one of the most widely supported IC packages — it fits perfboard, stripboard, and most prototype PCBs without a custom footprint.","metaTitle":"Texas Instruments CD74HCT107E JK Flip-Flop, 56 MHz, 14-DIP","metaDescription":"Texas Instruments CD74HCT107E dual JK flip-flop, 56 MHz clock, -55 to 125°C, 14-DIP.

Its maximum propagation delay is 43 ns at 4.5 V supply with a 50 pF load. This means the flip-flop's output settles within 43 ns after the clock edge, which sets the timing margin for downstream logic."},{"question":"Does the CD74HCT107E have a reset function?","answer":"Yes, the CD74HCT107E includes a reset input per flip-flop. When the reset pin is asserted, the flip-flop output is forced to a known state regardless of the clock or J/K inputs. This is useful for initializing counters or state machines to a known condition on power-up."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HCT107E","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HCT107E when reusing this data.
