Product details
Overview
74LV74D-Q100 from Nexperia is a dual positive-edge-triggered D-type flip-flop with independent asynchronous set (nSD) and reset (nRD) inputs, complementary Q/nQ outputs per channel, 1.0 V to 5.5 V supply range, -40 °C to +125 °C automotive temperature rating, and AEC-Q100 Grade 1 qualification-used for synchronous data latching and state storage in engine control units and ADAS sensor interfaces.
For engineers reviewing the 74LV74D-Q100 datasheet, 74LV74D-Q100 pinout, 74LV74D-Q100 application, or 74LV74D-Q100 equivalent, key selection considerations include propagation delay (13 ns @ 3.3 V), setup/hold times (8 ns / 3 ns), wide VCC tolerance, SO14 package compatibility, and automotive-grade reliability validation.
Technical Context
This device implements two independent CMOS D-type flip-flops, each triggered on the LOW-to-HIGH transition of its dedicated clock input (nCP). Each channel accepts asynchronous active-LOW set (nSD) and reset (nRD) signals that override clocked operation, enabling immediate state initialization without waiting for clock edges.
Input clamping diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The logic supports direct TTL-level compatibility (2.7 V–3.6 V) and operates reliably across 1.0 V–5.5 V, making it suitable for mixed-voltage automotive subsystems where rail translation is impractical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 5.5 V - Enables interoperability with 1.2 V logic, 3.3 V microcontrollers, and 5 V legacy systems without level shifters. |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood automotive applications including powertrain and chassis control. |
| Propagation Delay (tpd) | 13 ns max @ VCC = 3.0–3.6 V - Supports reliable 60 MHz clock operation in timing-critical control loops. |
| Setup/Hold Time | tsu = 8 ns, th = 3 ns @ VCC = 3.3 V - Defines minimum data stability window before and after clock edge for deterministic state capture. |
| Output Drive Strength | ±25 mA per output - Sufficient to drive multiple CMOS/TTL loads or small capacitive buses directly. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Meets stringent automotive ESD immunity requirements per JS-001/JS-002. |
| Power Dissipation | ICC ≤ 80 μA @ VCC = 5.5 V - Ultra-low static current enables use in always-on vehicle modules with strict quiescent power budgets. |
Pinout & Package
74LV74D-Q100 is housed in a plastic small outline package (SO14) per SOT108-1 standard: 14-pin, 3.9 mm body width, 1.27 mm pitch, gull-wing leads. Pin 1 marked by notch or bevel; pin 7 = GND, pin 14 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 (1RD, 2RD) | Asynchronous Reset (active-LOW) | Forces corresponding Q output LOW immediately, independent of clock-critical for fail-safe system initialization. |
| 2, 12 (1D, 2D) | Data Input | Samples and stores logic state on rising clock edge; must meet setup/hold timing relative to nCP. |
| 3, 11 (1CP, 2CP) | Clock Input (edge-triggered) | LOW-to-HIGH transition captures D-input value; internal Schmitt trigger ensures noise immunity on slow edges. |
| 4, 10 (1SD, 2SD) | Asynchronous Set (active-LOW) | Forces corresponding Q output HIGH immediately-used for known startup states or error recovery. |
| 5, 9 (1Q, 2Q) | True Output | Reflects stored D-state after clock edge; drives downstream logic or feedback paths. |
| 6, 8 (1Q, 2Q) | Complement Output | Inverted copy of Q output-enables differential signaling or eliminates external inverters in toggle configurations. |
| 7 | GND | Reference ground for all I/O and internal circuitry; requires low-impedance connection to minimize switching noise. |
| 14 | VCC | Primary supply rail; decoupling capacitor (100 nF) recommended within 5 mm of this pin for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling, humidity, and vibration stress testing. |
| Wide VCC range (1.0 V–5.5 V) | Eliminates need for external voltage translators in multi-rail ECUs, supporting both ultra-low-power 1.2 V domains and legacy 5 V sensors. |
| Input clamp diodes | Enable robust interface to overvoltage sources (e.g., LIN bus transceivers) using simple series resistors-no external protection required. |
| CMOS low-power design | Typical ICC = 20 μA @ 5.5 V, 25 °C-reduces thermal load and extends battery life in always-on vehicle modules. |
| TTL-level compatibility | Directly interfaces with 3.3 V TTL outputs without pull-ups or level shifters, simplifying integration with legacy MCU peripherals. |
Applications
| Engine Control Unit (ECU) | Advanced Driver Assistance Systems (ADAS) |

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 | Higher VCC max (6.5 V), lower tpd (7.5 ns @ 3.3 V), but only rated to +105 °C. | Lacks full +125 °C support-unsuitable for under-hood locations exceeding 105 °C ambient. | Select when higher speed and 6.5 V tolerance are needed, and ambient temperature remains ≤105 °C. |
| 74AUP2G74DC,125 | Ultra-low power (ICC < 1 μA), smaller XSON-8 package, but single-channel only and no AEC-Q100 grade. | Not qualified for automotive use; limited to infotainment or cabin electronics with non-safety-critical timing. | Choose for space-constrained, low-power cabin modules where AEC-Q100 is not mandated. |
Compared with SN74LVC74AQPWRQ1 and 74AUP2G74DC,125, the 74LV74D-Q100 uniquely balances +125 °C operation, 1.0 V minimum supply, and SO14 mechanical compatibility-making it the only option qualified for high-temp engine bay digital sequencing without derating or redesign.

FAQ
What is the maximum clock frequency supported by 74LV74D-Q100?
The device supports up to 100 MHz maximum clock frequency at VCC = 3.3 V and Tamb = 25 °C, with guaranteed operation to 48 MHz across the full -40 °C to +125 °C range. This is derived from the 26 ns maximum propagation delay (tpd) and 24 ns minimum pulse width (tW) specified in Table 7 of the datasheet.
Can 74LV74D-Q100 operate at 1.2 V supply voltage?
Yes-74LV74D-Q100 is fully functional at 1.2 V, with DC characteristics guaranteed from 1.2 V to 5.5 V. At 1.2 V, propagation delay increases to 70 ns and maximum frequency drops to ~14 MHz, but all logic functions, set/reset behavior, and input thresholds remain valid per Table 6 and Table 8.
How does the asynchronous reset differ from the clocked operation?
Asynchronous reset (nRD) forces the corresponding Q output LOW immediately upon signal assertion, regardless of clock state or timing-bypassing the edge-triggered path entirely. This provides deterministic, cycle-independent state clearing essential for safety-critical initialization and fault recovery sequences.
Is 74LV74D-Q100 pin-compatible with standard 74HC74 or 74LS74 packages?
No-74LV74D-Q100 uses the SO14 (SOT108-1) footprint, which matches the physical pinout of industry-standard 14-pin SOIC but differs electrically from 74HC74 (wider VCC range, lower drive) and 74LS74 (TTL input thresholds, higher power). Direct replacement requires verification of voltage levels, timing margins, and load drive capability.
