Product details
Overview
74HCT107D-Q100 from Nexperia is a dual negative-edge-triggered JK flip-flop with asynchronous active-LOW reset, TTL-compatible input levels, 14-pin SO14 package, -40 °C to +125 °C automotive temperature range, and AEC-Q100 Grade 1 qualification. It implements synchronous data latching and toggle functionality in digital control logic for engine management timing circuits.
For engineers reviewing the 74HCT107D-Q100 datasheet, 74HCT107D-Q100 pinout, 74HCT107D-Q100 application, or 74HCT107D-Q100 equivalent, key selection criteria include negative-edge clock triggering, independent J/K inputs per section, asynchronous reset behavior, TTL-level input compatibility, and automotive-grade thermal and reliability specs.
Technical Context
This device contains two independent JK flip-flops, each with separate J, K, clock (CP), and asynchronous reset (R) terminals. The flip-flops respond only to HIGH-to-LOW transitions on CP, and R overrides clocked operation by forcing Q = LOW and Q̅ = HIGH regardless of CP state.
Input levels conform to TTL thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V logic families. Internal clamp diodes allow safe interface to voltages exceeding VCC when used with current-limiting resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HCT - TTL-compatible CMOS, ensures interoperability with 5 V bipolar logic without level shifters |
| Trigger Edge | Negative edge (HIGH-to-LOW CP transition) - enables precise synchronization to falling clock edges in timing-critical control loops |
| Reset Type | Asynchronous, active LOW - guarantees immediate output override independent of clock phase, critical for fail-safe system initialization |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard automotive 5 V rail tolerances and supports robust operation under load dump or cold-crank conditions |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive applications including transmission control units |
| Propagation Delay | 19–54 ns (VCC = 4.5 V, CL = 50 pF) - determines maximum achievable state update rate in sequential logic chains |
| Power Dissipation | Max 500 mW (SO14, Tamb ≤ 100 °C) - defines thermal budget for PCB layout and adjacent component placement |
Pinout & Package
Package: SO14 (SOT108-1), plastic small outline, 14 leads, 3.9 mm body width, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | J input (Flip-flop 1, Flip-flop 2) | Synchronous data enable: HIGH sets Q on next clock edge if K = LOW; controls toggle/set behavior per function table |
| 2, 6 | Q̅ output (Flip-flop 1, Flip-flop 2) | Complementary output - provides inverted state for feedback paths or differential signaling without external inverters |
| 3, 5 | Q output (Flip-flop 1, Flip-flop 2) | True output - delivers registered state for downstream logic, counters, or status monitoring |
| 4, 11 | K input (Flip-flop 1, Flip-flop 2) | Synchronous data disable: HIGH resets Q on next clock edge if J = LOW; completes JK functional completeness |
| 9, 12 | CP input (Flip-flop 2, Flip-flop 1) | Negative-edge clock - sampling occurs only at HIGH-to-LOW transition, rejecting noise on rising edges |
| 10, 13 | R input (Flip-flop 2, Flip-flop 1) | Asynchronous reset - forces Q = LOW immediately, overriding all clocked behavior for emergency clear or power-on reset |
| 7 | GND | Reference ground plane - must be low-impedance connection to minimize switching noise coupling into sensitive latch nodes |
| 14 | VCC | Positive supply - powers internal CMOS circuitry; decoupling capacitor required within 10 mm of pin for stable edge response |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including humidity, vibration, and thermal cycling stress tests |
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V supply - eliminates need for external level translators when interfacing with legacy microcontrollers or discrete logic |
| Asynchronous active-LOW reset | Independent per flip-flop; asserts Q = 0 regardless of CP state - enables deterministic startup and fault recovery in safety-critical subsystems |
| Clamp diode protection | Integrated input diodes allow safe overvoltage tolerance up to ±20 mA - permits direct connection to 12 V signals via series resistor in mixed-voltage systems |
| Low dynamic power consumption | CPD = 30 pF per flip-flop - limits switching current and heat generation in high-frequency clock domains typical in engine timing sequencers |
Applications
| Engine Control Unit (ECU) Timing Sequencer | Transmission Control Module (TCM) Gear State Latch |
|---|---|
|
Use Scenario: Synchronizing camshaft and crankshaft position sampling across multiple cylinders using shared clock and reset signals. IC Role / Device Role / Timing Role: Dual JK flip-flop captures and holds synchronized edge-aligned sensor states, with asynchronous reset clearing latches before each combustion cycle. Use Value: Enables deterministic multi-phase timing alignment without software intervention, reducing CPU overhead and jitter in real-time ignition control. |
Use Scenario: Capturing and retaining gear selection status from mechanical switch arrays during shifting transients. IC Role / Device Role / Timing Role: Each JK section stores one gear bit; J/K inputs configure set/reset behavior while negative-edge CP samples switch bounce-filtered signals. Use Value: Provides hardware-based metastability immunity and glitch-free state retention during high-noise transmission actuation events. |
| Body Control Module (BCM) Door Lock Sequence Controller | Advanced Driver Assistance System (ADAS) Sensor Sync Buffer |
|
Use Scenario: Managing timed lock/unlock sequences with interlocked enable conditions and timeout resets. IC Role / Device Role / Timing Role: Flip-flops implement finite-state steps (e.g., "unlock request → verify → actuate") with R input tied to global safety timeout signal. Use Value: Delivers fail-safe hardware sequencing that remains functional even during MCU brownout or firmware hang conditions. |
Use Scenario: Aligning timestamped radar and camera trigger pulses to a common reference clock edge before fusion processing. IC Role / Device Role / Timing Role: One section latches radar pulse edge; second latches camera edge - both synchronized to same CP, enabling sub-microsecond skew measurement. Use Value: Reduces inter-sensor timing uncertainty to <50 ns, improving object tracking accuracy in high-speed collision avoidance algorithms. |
Equivalent & Alternatives

FAQ
What is the minimum setup time required for J and K inputs before the clock edge?
The 74HCT107D-Q100 requires a minimum setup time (tsu) of 20 ns at VCC = 4.5 V, measured from the HIGH-to-LOW clock transition. This ensures reliable state capture and prevents metastability. Setup time increases to 25 ns over the full -40 °C to +125 °C operating range per datasheet Table 7.
Can the asynchronous reset be used independently for each flip-flop?
Yes - pins 10 and 13 serve as dedicated, isolated asynchronous reset inputs for flip-flop 2 and flip-flop 1 respectively. Each R input forces its corresponding Q output LOW and Q̅ HIGH immediately, with no dependency on the other section's clock or reset state.
Does this device support hot insertion or live swapping in powered systems?
No - the 74HCT107D-Q100 lacks IOFF protection or power-off isolation. Applying VCC after signal inputs may cause latch-up or excessive current due to internal clamp diode conduction. Power sequencing must ensure VCC is stable before applying input signals.
How does the propagation delay vary between Q and Q̅ outputs?
Propagation delay from CP to Q and CP to Q̅ is matched within ±1 ns across temperature and voltage ranges per datasheet Table 7. At VCC = 4.5 V and 25 °C, both tPHL and tPLH are specified at 19–36 ns, ensuring symmetrical timing for differential feedback or complementary control paths.
