Product details
Overview
74LV74PW-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 74LV74PW-Q100 datasheet, 74LV74PW-Q100 pinout, 74LV74PW-Q100 application, or 74LV74PW-Q100 equivalent, key selection criteria include propagation delay (13 ns typical at 3.3 V), setup/hold timing (8 ns / 3 ns at 3.3 V), low-voltage operation down to 1.0 V, and TSSOP14 package compatibility with high-density automotive PCB layouts.
Technical Context
This device implements two independent edge-triggered D flip-flops sharing no internal logic; each has dedicated nD, nCP, nSD, nRD, nQ, and nQ terminals. The asynchronous nSD/nRD inputs override clock action and force outputs to defined states regardless of clock edge timing.
CMOS architecture enables rail-to-rail input compatibility (VIH = 0.7VCC, VIL = 0.3VCC), direct TTL interfacing at 2.7–3.6 V, and low ICC (20 μA typical at 5.5 V). Input clamp diodes allow safe interface to voltages exceeding VCC when current-limiting resistors are used.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 5.5 V - supports legacy 1.2 V logic, 1.8 V/2.5 V/3.3 V microcontrollers, and 5 V legacy systems without level shifters. |
| Propagation Delay (nCP→nQ) | 13 ns typical at VCC = 3.3 V, CL = 15 pF - enables reliable operation up to 60 MHz in synchronous control paths. |
| Setup/Hold Time (nD→nCP) | 8 ns / 3 ns at VCC = 3.3 V - defines minimum data stability window before and after clock edge for deterministic sampling. |
| Output Drive Strength | ±6 mA at VCC = 3.0 V - sufficient to drive multiple 74LVC inputs or small capacitive loads (< 30 pF) without buffering. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive board-level ESD robustness requirements per ISO 10605. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive environments including powertrain and chassis modules. |
Pinout & Package
TSSOP14 plastic thin shrink small outline package (SOT402-1); 14-lead, 4.4 mm body width, 0.65 mm pitch; RoHS-compliant, lead-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 | nRD (asynchronous reset) | Active-LOW direct reset for Flip-Flop 1 and 2 respectively; forces nQ = LOW, nQ = HIGH independent of clock. |
| 2, 12 | nD (data input) | Primary synchronous data input for each flip-flop; sampled on LOW-to-HIGH nCP transition if setup/hold met. |
| 3, 11 | nCP (clock input) | Positive-edge-triggered clock; initiates data capture only on rising edge; insensitive to pulse width beyond minimum tW = 8 ns. |
| 4, 10 | nSD (asynchronous set) | Active-LOW direct set for Flip-Flop 1 and 2 respectively; forces nQ = HIGH, nQ = LOW independent of clock. |
| 5, 9 | nQ (true output) | Non-inverted registered output; reflects stored nD value after valid nCP edge or nSD/nRD assertion. |
| 6, 8 | nQ (complement output) | Inverted registered output; always opposite logic state of corresponding nQ terminal. |
| 7 | GND | Ground reference (0 V) for all I/O and internal circuitry; requires low-impedance connection to system ground plane. |
| 14 | VCC | Primary power supply; must be decoupled with ≥100 nF ceramic capacitor near pin to suppress switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across -40 °C to +125 °C ambient, including accelerated lifetime testing and failure mode analysis. |
| Wide VCC range (1.0 V–5.5 V) | Eliminates need for external voltage translators when interfacing mixed-voltage subsystems (e.g., 1.8 V MCU to 3.3 V sensor bus). |
| Input clamp diodes | Enables safe connection to signals up to 7 V using series current-limiting resistors-critical for wake-up line monitoring in sleep-mode ECUs. |
| Low dynamic power (CPD = 24 pF) | Reduces switching current draw and heat generation in battery-powered modules; PD ≈ 0.4 mW at 10 MHz, 3.3 V. |
| Latch-up immunity > 100 mA | Meets JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events in 12 V automotive systems. |
Applications
| Engine Control Unit (ECU) | Advanced Driver Assistance Systems (ADAS) |
|---|---|
|
Use Scenario: Capturing camshaft/crankshaft position sensor pulses synchronized to ignition timing.

Use Value: Enables deterministic edge alignment with microcontroller timer capture registers while supporting fail-safe reset via diagnostic controller. |
Use Scenario: Synchronizing radar echo timing signals across multiple antenna channels before ADC sampling. IC Role / Device Role / Timing Role: Provides metastability-hardened input staging for asynchronous sensor data; Q/nQ outputs feed parallel sample-and-hold control logic. Use Value: Reduces timing uncertainty between channels to <1 ns (via matched trace lengths and identical propagation paths), improving Doppler resolution. |
| Body Control Module (BCM) | Infotainment System Interface |
|
Use Scenario: Debouncing door lock/unlock switch inputs subject to mechanical bounce and EMI in 12 V vehicle harnesses. IC Role / Device Role / Timing Role: Uses asynchronous nSD/nRD to force known output state during power-up; clocked nD input filters noisy switch transitions. Use Value: Eliminates software debouncing overhead and ensures deterministic lock actuation within 20 ms of switch press, even during brown-out conditions. |
Use Scenario: Level-shifting and synchronizing I²C clock/data lines between 1.8 V SoC and 3.3 V display driver ICs. IC Role / Device Role / Timing Role: Acts as bidirectional data register with independent clock domains; nQ outputs drive pull-up networks on 3.3 V side. Use Value: Prevents I²C bus lockup during voltage domain crossing by enforcing strict setup/hold margins and eliminating race conditions. |
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 |
|---|---|---|---|
| SN74LVC74APWR | Wider industrial temp range (-40 °C to +125 °C), but not AEC-Q100 qualified; 1.65 V–3.6 V VCC only. | Suitable for non-automotive industrial controls; lacks automotive reliability validation and extended voltage support. | Select when cost sensitivity outweighs automotive qualification needs and system operates strictly at 1.8 V/3.3 V. |
| 74AUP2G74DC | Ultra-low power (ICC < 1 μA), 0.8 V–3.6 V VCC, but only 20 MHz max fmax at 3.3 V and no AEC-Q100 Grade 1 rating. | Better for battery-backed memory retention or ultra-low-power wake-up logic-not for real-time control loops. | Choose for energy-constrained modules where timing margin > 3× required and automotive qualification is not mandated. |
Compared with SN74LVC74APWR and 74AUP2G74DC, the 74LV74PW-Q100 uniquely combines AEC-Q100 Grade 1 certification, 1.0 V–5.5 V operation, and 60 MHz performance at 3.3 V-making it the only option qualified for safety-critical automotive timing functions requiring both wide voltage tolerance and high-speed response.

FAQ
What is the minimum VCC required for guaranteed operation of the 74LV74PW-Q100?
The 74LV74PW-Q100 is guaranteed to function down to VCC = 1.0 V, with DC characteristics fully specified from VCC = 1.2 V to 5.5 V. At 1.0 V, input levels are referenced to GND or VCC only; timing parameters are not characterized below 1.2 V per datasheet Section 8.
Can the 74LV74PW-Q100 drive standard 74LVC inputs directly?
Yes-the 74LV74PW-Q100 provides ±6 mA output drive at VCC = 3.0 V, matching the input current requirements of 74LVC gates. Its VOH/VOL specifications (2.40 V/0.25 V min/max at 3.0 V, 6 mA load) exceed 74LVC thresholds, enabling direct fanout of up to 10 loads without buffers.
How does the asynchronous reset (nRD) interact with the clock input (nCP)?
The nRD input is asynchronous and dominant: when asserted LOW, it forces nQ = LOW and nQ = HIGH immediately, overriding any ongoing clock activity or data input state. This action occurs independently of nCP timing and takes effect within trec = 8 ns (max) after nRD deassertion, per Table 7.
Is the TSSOP14 package (SOT402-1) pin-compatible with the SO14 version (74LV74D-Q100)?
Yes-both packages share identical pin numbering and electrical functionality per Figures 5 and 6. The 74LV74PW-Q100 (TSSOP14) and 74LV74D-Q100 (SO14) are functionally and pinout-compatible; only mechanical dimensions and thermal characteristics differ, with TSSOP offering higher density and lower profile for space-constrained automotive PCBs.
