Product details
Overview
74LVC74AD-Q100 from Nexperia is a dual positive-edge-triggered D-type flip-flop with asynchronous active-LOW set (nSD) and reset (nRD), 14-pin SO14 package, 1.2 V to 3.6 V supply range, -40 °C to +125 °C automotive temperature grade, and Schmitt-trigger inputs for noise immunity. It enables synchronous data latching in engine control units, ADAS sensor interfaces, and body electronics where deterministic timing and AEC-Q100 Grade 1 compliance are required.
For engineers reviewing the 74LVC74AD-Q100 datasheet, 74LVC74AD-Q100 pinout, 74LVC74AD-Q100 application, or 74LVC74AD-Q100 equivalent, this page delivers verified functional behavior, exact pin roles per SOT108-1 layout, automotive-grade timing margins (e.g., 2.0 ns setup at 3.3 V), and validated alternatives for dual DFF replacement in safety-critical signal conditioning paths.
Technical Context
This device implements two independent edge-triggered D flip-flops sharing no internal coupling-each with dedicated nD, nCP, nSD, nRD, nQ, and nQ terminals. The asynchronous set/reset operate independently of clock edges and override all synchronous operations when asserted LOW.
Schmitt-trigger inputs ensure robust operation with slow-rising signals (≤10 ns/V transition rate supported), while propagation delays (tpd ≤ 5.2 ns at VCC = 3.3 V) and output skew (≤1.0 ns) guarantee tight timing alignment between Q/Q̅ pairs across both flip-flops under automotive thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - supports direct interfacing with 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
| Max Clock Frequency | 150 MHz at VCC = 3.3 V - enables high-speed sampling in CAN/LIN bus synchronization logic |
| Setup/Hold Time | tsu = 2.0 ns / th = 1.0 ns at VCC = 3.3 V - defines minimum data stability window before/after clock edge for reliable capture |
| Propagation Delay | tpd ≤ 5.2 ns (nCP → nQ) at VCC = 3.3 V - ensures sub-6 ns path delay for real-time control loop timing budgets |
| Input Voltage Tolerance | 5 V tolerant inputs - allows mixed-voltage system integration with legacy 5 V peripherals |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive board-level ESD robustness requirements |
Pinout & Package
74LVC74AD-Q100 uses the SO14 (SOT108-1) plastic small outline package: 14-lead, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads. Pin 1 index located at top-left corner with notch marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 (1RD, 2RD) | Asynchronous Reset (active LOW) | Forces corresponding nQ to LOW regardless of clock state; critical for power-on initialization and fault recovery |
| 2, 12 (1D, 2D) | Data Input | Samples input value on LOW-to-HIGH clock transition; must be stable ≥2.0 ns before edge at 3.3 V |
| 3, 11 (1CP, 2CP) | Clock Input | Positive-edge-triggered; Schmitt-trigger input accepts slow edges up to 10 ns/V rise/fall rate |
| 4, 10 (1SD, 2SD) | Asynchronous Set (active LOW) | Forces corresponding nQ to HIGH regardless of clock; used for known-state startup or error override |
| 5, 9 (1Q, 2Q) | True Output | Complementary to nQ̅; drives downstream logic with VOH ≥ 2.2 V / VOL ≤ 0.55 V at 24 mA load |
| 6, 8 (1Q̅, 2Q̅) | Complement Output | Provides inverted latch state; enables differential signaling or XOR-based edge detection |
| 7 | GND | Reference ground plane; decoupling capacitor must be placed within 5 mm for stable switching |
| 14 | VCC | Primary supply rail; requires local 100 nF ceramic bypass capacitor adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from -40 °C to +125 °C ambient, including thermal cycling and humidity exposure |
| Dual independent flip-flops | No shared control logic-enables parallel data capture paths without cross-talk or timing dependency |
| Schmitt-trigger inputs | Input hysteresis ≥0.3 V at 3.3 V eliminates false triggering from noisy harness or long PCB traces |
| 5 V tolerant inputs | Accepts 0–5.5 V input levels while powered from 1.2–3.6 V supply-eliminates external level translators |
| Low dynamic power | CPD = 19.1 pF at 3.3 V enables <1 mW typical power at 10 MHz toggle rate with 15 pF load |
Applications
| Engine Control Unit (ECU) Timing Sync | ADAS Camera Sensor Interface |
|---|---|
|
Use Scenario: Synchronizing pulse-width modulated injector drive signals with crankshaft position encoder edges.

| Body Control Module (BCM) Door Lock Logic | Automotive Infotainment Display Backlight Control |
|
Use Scenario: Debouncing mechanical door lock/unlock switch inputs and generating clean edge-triggered commands to motor drivers. IC Role / Device Role / Timing Role: Schmitt-trigger inputs suppress contact bounce; dual DFF provides synchronized, glitch-free enable signals to H-bridge gate drivers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC74AQPWRQ1 | TSSOP14 (SOT402-1) package; identical electrical specs but 0.65 mm pitch vs SO14's 1.27 mm | Better thermal performance in high-density layouts; requires finer-pitch reflow profile | Select when board space is constrained and AOI-compatible solder joint inspection is needed |
| 74LVC74ABQ-Q100 | DHVQFN14 (SOT762-1) package; same die, 2.5 × 3 mm footprint, side-wettable flanks for automated optical inspection | Superior thermal resistance (9.6 mW/K derating above 98 °C); no leads reduce parasitic inductance | Preferred for under-hood modules requiring maximum thermal margin and X-ray/AOI process validation |
Compared with SN74LVC74AQPWRQ1 and 74LVC74ABQ-Q100, the 74LVC74AD-Q100 offers the largest lead pitch and highest manufacturability in standard wave-solder or hand-soldered prototyping, while maintaining identical timing, voltage, and AEC-Q100 compliance-making it optimal for first-article builds and service replacement.

FAQ
What is the minimum supply voltage for guaranteed operation of the 74LVC74AD-Q100?
The 74LVC74AD-Q100 is fully specified down to 1.2 V supply voltage, with static and dynamic parameters-including setup time, propagation delay, and output drive-guaranteed across the full -40 °C to +125 °C temperature range at this voltage. Below 1.2 V, functionality is not assured per datasheet limits.
Can the 74LVC74AD-Q100 interface directly with 5 V TTL logic outputs?
Yes-the 74LVC74AD-Q100 features 5 V tolerant inputs, allowing direct connection to 5 V TTL outputs without external level-shifting circuitry. Input voltage rating extends to 5.5 V, and VIH/VIL thresholds scale with VCC, ensuring correct logic interpretation even at 1.2 V supply.
How does the Schmitt-trigger input improve noise immunity in automotive environments?
Schmitt-trigger inputs provide hysteresis (≥0.3 V at 3.3 V), meaning the threshold for detecting a HIGH differs from that for detecting a LOW. This prevents multiple toggles caused by slow or noisy edges-common in long harness runs or near high-current actuators-and eliminates need for external RC filtering.
Is the SO14 package (SOT108-1) lead-free and RoHS compliant?
Yes-the 74LVC74AD-Q100 in SO14 packaging is manufactured using lead-free solderable terminations and complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with full material declarations available via Nexperia's product change notifications.
