Product details
Overview
74LVC74APW-Q100 from Nexperia is an automotive-grade dual positive-edge-triggered D-type flip-flop with asynchronous active-LOW set (nSD) and reset (nRD), 14-pin TSSOP package, 1.2 V to 3.6 V supply range, and AEC-Q100 Grade 1 qualification for use in engine control units and ADAS domain controllers.
For engineers reviewing the 74LVC74APW-Q100 datasheet, 74LVC74APW-Q100 pinout, 74LVC74APW-Q100 application, or 74LVC74APW-Q100 equivalent, this page delivers verified functional behavior, timing constraints (tsu = 2.0 ns @ 3.6 V), output skew ≤1.5 ns, Schmitt-trigger input tolerance, and automotive thermal validation (-40 °C to +125 °C).
Technical Context
This device implements two independent edge-triggered D flip-flops sharing no internal logic coupling; each has dedicated nD, nCP, nSD, nRD, nQ, and nQ terminals. The asynchronous nSD/nRD inputs override clock action and operate at any valid supply voltage within 1.2 V–3.6 V.
Its Schmitt-trigger inputs accept slow-rising signals (Δt/ΔV down to 10 ns/V at 3.6 V), enabling robust interfacing with noisy sensors or legacy 5 V TTL outputs while maintaining CMOS low-power operation (ICC ≤ 40 μA @ 3.6 V, -40 °C to +125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - Enables direct integration into 1.8 V, 2.5 V, and 3.3 V automotive subsystems without level-shifting. |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications. |
| Propagation Delay (tpd) | 1.0 ns to 6.5 ns - Measured nCP→nQ at VCC = 3.0–3.6 V; supports >120 MHz clock rates in high-speed control loops. |
| Set-up Time (tsu) | 2.0 ns @ VCC = 3.0–3.6 V - Defines minimum data stability window before clock edge for reliable state capture. |
| Output Skew (tsk(o)) | ≤1.5 ns - Guarantees tight timing alignment between complementary outputs of same flip-flop, critical for glitch-free sampling. |
| Input Clamping | 5 V tolerant - Allows safe interfacing with legacy 5 V logic without external protection diodes. |
| ESD Rating | HBM >2000 V, CDM >1000 V - Meets automotive ESD robustness requirements for assembly and field operation. |
Pinout & Package
TSSOP14 plastic thin shrink small outline package (SOT402-1); 14 leads; body width 4.4 mm; lead pitch 0.65 mm; exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 (1RD, 2RD) | Asynchronous reset (active LOW) | Forces nQ = LOW regardless of clock or data; used for system initialization or fault recovery. |
| 2, 12 (1D, 2D) | Data input | Samples logic level on rising clock edge; requires stable tsu = 2.0 ns prior to transition @ 3.6 V. |
| 3, 11 (1CP, 2CP) | Clock input (LOW-to-HIGH edge) | Triggers synchronous state update; Schmitt-trigger input accepts slow edges up to 10 ns/V. |
| 4, 10 (1SD, 2SD) | Asynchronous set (active LOW) | Forces nQ = HIGH independently of clock; enables priority override in safety-critical sequences. |
| 5, 9 (1Q, 2Q) | True output | Reflects stored D value after clock edge; drives loads up to 24 mA @ 3.0 V (VOH ≥ 2.2 V). |
| 6, 8 (1Q, 2Q) | Complement output | Provides inverted logic state; supports differential signaling or enable/disable pairing. |
| 7 | GND | Reference ground terminal; must be connected to system 0 V plane for noise immunity and timing integrity. |
| 14 | VCC | Primary supply rail; decoupling capacitor (100 nF) required within 5 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from -40 °C to +125 °C in automotive powertrain and chassis systems. |
| 5 V tolerant inputs | Accepts 0–5.5 V input signals without damage or level-shifting, simplifying mixed-voltage board design. |
| Schmitt-trigger inputs | Enables reliable operation with slow-rising sensor signals or long PCB traces (min Δt/ΔV = 10 ns/V @ 3.6 V). |
| Low dynamic power | CPD = 19.1 pF @ 3.3 V enables <100 μW/MHz dynamic dissipation in battery-sensitive modules. |
| Multiple package options | TSSOP14 (SOT402-1) offers compact footprint and AOI-compatible solder joints for high-reliability SMT lines. |
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 |
|---|---|---|---|
| SN74LVC74APWR | Industrial grade (-40 °C to +85 °C); identical pinout and AC specs but lacks AEC-Q100 qualification and extended temp range. | Not suitable for under-hood deployment; acceptable for cabin infotainment or gateway modules. | Select only if automotive qualification is unnecessary and cost sensitivity outweighs thermal margin requirements. |
| 74LVC74ABQ-Q100 | DHVQFN14 package (2.5 × 3 mm); same AEC-Q100 Grade 1 rating and electrical specs; no leads, side-wettable flanks for AOI. | Better thermal performance (9.6 mW/K derating above 98 °C) and smaller footprint than TSSOP14. | Prefer for space-constrained EPS or ADAS camera modules where thermal density and reflow inspection are critical. |
Compared with SN74LVC74APWR, the 74LVC74APW-Q100 adds automotive qualification and +125 °C operation at no speed penalty; versus 74LVC74ABQ-Q100, it trades package size and thermal efficiency for easier manual rework and legacy TSSOP compatibility.

FAQ
What is the maximum clock frequency supported by the 74LVC74APW-Q100?
The device supports up to 150 MHz at VCC = 3.0–3.6 V and ambient temperatures up to +125 °C, as confirmed by fmax test data in Table 8 of the datasheet. At lower voltages (e.g., 1.8 V), maximum frequency reduces to 20 MHz due to increased propagation delay.
Can the 74LVC74APW-Q100 interface directly with 5 V microcontrollers?
Yes - its inputs are 5 V tolerant (VI up to 5.5 V), allowing direct connection to 5 V GPIOs without level shifters. However, outputs swing only to VCC (max 3.6 V), so bidirectional 5 V communication requires external pull-ups or translators.
How does the Schmitt-trigger input improve system reliability?
Schmitt-trigger inputs provide hysteresis (typical 0.3–0.5 V), rejecting noise-induced false triggering on slow-rising signals from inductive sensors or long harness runs. This eliminates need for external RC filtering in engine bay applications.
Is the TSSOP14 package suitable for automated optical inspection (AOI)?
Yes - the SOT402-1 package features gull-wing leads compatible with standard AOI systems. While DHVQFN14 (SOT762-1) offers side-wettable flanks for enhanced solder-joint verification, TSSOP14 remains fully inspectable using conventional top-down imaging.
