Product details
Overview
74LVC374ABQ-Q100 from Nexperia is an automotive-grade octal positive-edge-triggered D-type flip-flop with 3-state outputs, 1.2 V to 3.6 V supply range, 5.5 V overvoltage-tolerant inputs/outputs, and IOFF partial power-down protection. It operates across −40 °C to +125 °C and supports mixed-voltage translation between 3.3 V and 5 V systems in body control modules and ADAS domain controllers.
For engineers reviewing the 74LVC374ABQ-Q100 datasheet, 74LVC374ABQ-Q100 pinout, 74LVC374ABQ-Q100 application, or 74LVC374ABQ-Q100 equivalent, this device delivers deterministic register timing (tpd ≤ 9.0 ns at 3.6 V), low dynamic power (CPD = 15.4 pF), Schmitt-trigger input noise immunity, and AEC-Q100 Grade 1 qualification for automotive signal latching and bus isolation tasks.
Technical Context
This device implements eight independent edge-triggered D flip-flops sharing a common clock (CP) and output enable (OE) control. Each flip-flop samples its D-input on the LOW-to-HIGH CP transition and holds state until the next valid clock edge, with set-up time as low as 2.0 ns and hold time of 1.5 ns at 3.6 V.
The 3-state output buffers are fully decoupled from register operation: OE assertion forces Qn outputs into high-impedance regardless of internal flip-flop state, enabling shared-bus applications without data corruption. IOFF circuitry disables outputs when VCC = 0 V, preventing backflow current during partial power-down sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.2 V to 3.6 V - enables direct interface with 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters |
| Input voltage tolerance | −0.5 V to +5.5 V - allows safe connection to 5 V sources in mixed-voltage systems |
| Propagation delay (tpd) | 1.5 ns to 9.0 ns - ensures sub-10 ns register-to-bus timing for real-time control loops |
| Maximum clock frequency | 120 MHz at −40 °C to +125 °C - supports high-speed sampling in engine control units |
| IOFF leakage current | ±10 μA at VCC = 0 V - guarantees <100 μW standby power in powered-down subsystems |
| ESD protection | HBM >2000 V, CDM >1000 V - meets automotive board-level robustness requirements |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood and transmission control environments |
Pinout & Package
DHVQFN20 package (SOT764-1): 2.5 mm × 4.5 mm × 0.85 mm body, side-wettable flanks for AOI-compatible solder joint inspection, no leads, 20-terminal quad flat layout with exposed thermal pad (non-soldered by default).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE | Active-LOW output enable - disables all Qn outputs to high-impedance independently of register state |
| 2–5, 7–8, 13–14, 17–18 | D0–D7 | Data inputs - sampled on rising CP edge; tolerate 5.5 V regardless of VCC |
| 6, 9, 12, 15–16, 19 | Q0–Q7 | 3-state outputs - driven HIGH/LOW or tri-stated based on OE and register content |
| 10 | GND | Ground reference - 0 V return path for all signals and power |
| 11 | CP | Clock input - LOW-to-HIGH edge triggers synchronous capture of all Dn inputs |
| 20 | VCC | Supply voltage - powers internal logic and output drivers; range 1.2 V–3.6 V |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation in safety-critical automotive ECUs |
| IOFF partial power-down | Prevents destructive back-current when VCC is off but I/O lines remain active |
| Schmitt-trigger inputs | Enables reliable latching of slow-rising signals (e.g., sensor outputs, switch debouncing) |
| Independent register & buffer control | OE can disable outputs without altering stored Dn values - essential for bus arbitration |
| Side-wettable flanks (DHVQFN) | Supports automated optical inspection of solder joints for zero-defect automotive manufacturing |
Applications
| Body Control Module (BCM) | Advanced Driver Assistance Systems (ADAS) |
|---|---|
|
Use Scenario: Latching door lock status, window position, and mirror adjustment commands from microcontroller GPIOs before routing to actuator drivers. IC Role / Device Role / Timing Role: Octal register holding command states synchronously with system clock; 3-state outputs isolate MCU pins during CAN message transmission. Use Value: Prevents bus contention during concurrent communication and actuation; IOFF protects latch state during sleep mode transitions. |
Use Scenario: Buffering camera sensor pixel data streams between image signal processor and FPGA-based vision processing pipeline. IC Role / Device Role / Timing Role: Synchronizing parallel 8-bit video data to a centralized clock domain while enabling dynamic bus release for multi-sensor arbitration. Use Value: Eliminates metastability in cross-clock-domain transfers; 9.0 ns tpd ensures <10 ns skew across all 8 bits for frame-aligned capture. |
| Powertrain Control Unit (PCU) | Infotainment Head Unit |
|
Use Scenario: Capturing throttle position sensor (TPS) and crankshaft position sensor (CKP) digital outputs for engine timing calculations. IC Role / Device Role / Timing Role: Edge-triggered storage of sensor status bits with precise setup/hold timing (tsu = 2.0 ns, th = 1.5 ns at 3.6 V). Use Value: Guarantees deterministic sampling at up to 120 MHz clock rates required for real-time combustion cycle synchronization. |
Use Scenario: Isolating display interface signals (e.g., RGB data bus) from baseband processor during HDMI hot-plug detection events. IC Role / Device Role / Timing Role: 3-state output buffer enabling clean bus release without glitches when display controller resets. Use Value: Prevents visual artifacts during display reconfiguration; 5.5 V tolerant inputs accept legacy 5 V panel interface signals directly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC374AQPWRQ1 | TSSOP20 package (SOT360-1); identical electrical specs but 4.4 mm body width and higher thermal resistance (10.0 mW/K derating above 100 °C) | Better suited for manual rework or legacy PCB footprints requiring gull-wing leads | Select when board assembly uses traditional reflow profiles incompatible with QFN or requires visual solder inspection |
| 74LVC374APW-Q100 | Same TSSOP20 package as SN74LVC374AQPWRQ1; functionally identical but manufactured by Nexperia with full AEC-Q100 documentation traceability | Preferred for Tier 1 automotive programs requiring single-source compliance evidence and lot-level test reports | Choose when audit readiness, PPAP submission, or OEM-specific qualification records are mandatory |
Compared with SN74LVC374AQPWRQ1 and 74LVC374APW-Q100, the 74LVC374ABQ-Q100 offers superior thermal performance (12.9 mW/K derating above 111 °C) and AOI-compatible side-wettable flanks - critical for high-reliability automated SMT lines in modern automotive electronics manufacturing.

FAQ
Is the 74LVC374ABQ-Q100 pin-compatible with standard 74LVC374A variants?
Yes - it shares identical pin functions and ordering logic with other 74LVC374A-Q100 variants (e.g., SO20 and TSSOP20 packages), though physical pin locations differ due to DHVQFN20 layout. The functional mapping of D0–D7, Q0–Q7, CP, OE, VCC, and GND matches JEDEC-standard 20-pin octal flip-flop topology.
What is the maximum allowable input voltage when VCC = 1.2 V?
The absolute maximum input voltage remains −0.5 V to +5.5 V regardless of VCC level. This overvoltage tolerance allows safe interfacing with 5 V peripherals even when the device operates at 1.2 V, eliminating external level shifters in mixed-supply systems.
How does the IOFF feature behave during power sequencing?
When VCC drops to 0 V, the IOFF circuit actively disables all outputs, limiting OFF-state leakage to ±10 μA. This prevents reverse current flow from live 5 V buses into the unpowered IC, protecting both the flip-flop and upstream drivers during controlled power-down sequences.
Can the 74LVC374ABQ-Q100 drive a 50 pF load at 120 MHz?
No - while fmax reaches 120 MHz under recommended conditions, dynamic loading must be evaluated per CPD = 15.4 pF. Driving 50 pF at high frequency increases dynamic power (PD = CPD × VCC² × fi × N) and may exceed thermal limits; typical use assumes ≤30 pF loads for sustained 120 MHz operation.
