Product details
Overview
74LVC74ABQ,115 from Nexperia is a dual positive-edge-triggered D-type flip-flop with asynchronous active-LOW set (1SD/2SD) and reset (1RD/2RD), 14-terminal DHVQFN package, 1.2 V to 3.6 V supply range, and operation up to +125 °C - used for synchronous data latching and state storage in low-voltage digital control logic.
For engineers reviewing the 74LVC74ABQ,115 datasheet, 74LVC74ABQ,115 pinout, 74LVC74ABQ,115 application, or 74LVC74ABQ,115 equivalent, this device supports precise edge-triggered state capture with sub-7 ns propagation delay at 3.3 V, Schmitt-trigger inputs for noise immunity, and 5 V-tolerant inputs enabling mixed-voltage interfacing in industrial I/O and timing-critical control systems.
Technical Context
The 74LVC74ABQ implements two independent CMOS D-flip-flops sharing no internal coupling; each has dedicated clock (1CP/2CP), data (1D/2D), asynchronous set (1SD/2SD), reset (1RD/2RD), true (1Q/2Q), and complement (1Q/2Q) terminals. Clock triggering occurs on LOW-to-HIGH transitions only.
All inputs feature Schmitt-trigger action, ensuring robust operation with slow-rising signals (≤10 ns/V at 3.3 V), while asynchronous set/reset override clock and data, asserting outputs immediately without clock dependency - critical for power-on initialization and fault recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - enables direct integration into battery-powered and multi-rail 1.8 V/2.5 V/3.3 V systems without level shifters. |
| Propagation Delay (tpd) | 1.0 ns to 6.5 ns (VCC = 3.0–3.6 V) - ensures sub-7 ns timing margin for 120 MHz synchronous operation in real-time control loops. |
| Maximum Clock Frequency (fmax) | 120 MHz at VCC = 3.3 V, -40 °C to +125 °C - supports high-speed sampling and state machine sequencing in industrial PLCs and motor drives. |
| Input Voltage Tolerance | 5 V tolerant on all inputs - allows safe connection to legacy 5 V logic buses without external clamping or translation. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules, industrial automation controllers, and outdoor telecom equipment. |
| ESD Protection | HBM >2000 V, CDM >1000 V - provides robust handling during PCB assembly and field service in electrostatic-prone environments. |
| Power Dissipation Capacitance (CPD) | 19.1 pF at VCC = 3.3 V - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal-aware board layout. |
Pinout & Package
DHVQFN14 (SOT762-1) package: 2.5 mm × 3.0 mm × 0.85 mm body, 14 exposed terminals, no leads, thermal-enhanced construction with exposed die pad (non-soldered or GND-connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1RD, 13RD | Asynchronous reset (active LOW) | Forces 1Q/2Q to LOW independently of clock - used for emergency shutdown or system reset assertion. |
| 1D, 12D | Data input | Samples logic state at rising clock edge; must be stable ≥2.0 ns before CP transition (tsu) at 3.3 V. |
| 1CP, 11CP | Clock input (edge-triggered) | Triggers data transfer on LOW-to-HIGH transition only; Schmitt-trigger input rejects noise <1.0 V amplitude. |
| 1SD, 10SD | Asynchronous set (active LOW) | Forces 1Q/2Q to HIGH regardless of clock - enables immediate state initialization or fault flag assertion. |
| 1Q, 5Q / 2Q, 9Q | True output | Reflects sampled data after clock edge; drives TTL/CMOS loads up to 24 mA sink/source at 3.3 V. |
| 1Q, 6Q / 2Q, 8Q | Complement output | Provides inverted latched value - eliminates need for external inverters in toggle or differential signaling paths. |
| 7GND | Ground reference | Primary return path for all internal logic and I/O; requires low-inductance PCB connection for signal integrity. |
| 14VCC | Supply voltage | Power rail for core logic and I/O buffers; decoupling capacitor (100 nF) required within 3 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant inputs | Enables direct interface with legacy 5 V microcontrollers and sensors without level-shifting circuitry. |
| Schmitt-trigger inputs | Accepts slow-rising signals down to 10 ns/V at 3.3 V - eliminates need for external RC filtering in noisy industrial environments. |
| Wide temperature range | Specified from -40 °C to +125 °C - supports deployment in engine control units, solar inverters, and railway signaling hardware. |
| Low dynamic power | CPD = 19.1 pF at 3.3 V enables <10 μW/MHz typical dynamic power - reduces thermal load in dense logic arrays. |
| JEDEC-compliant voltage standards | Meets JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) - ensures interoperability across multi-vendor 1.8 V/2.5 V/3.3 V systems. |
Applications
| Industrial PLC Input Latching | Automotive Body Control Module |
|---|---|
|
Use Scenario: Capturing momentary switch closures from factory floor pushbuttons into deterministic scan-cycle registers. IC Role / Device Role / Timing Role: Dual D-flip-flop latches debounced inputs on synchronized PLC clock edges, providing glitch-free state capture.

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 |
|---|---|---|---|
| SN74LVC74APWRE4 | TSSOP14 package (SOT402-1); 4.4 mm body width; 0.65 mm pitch; no exposed thermal pad. | Larger footprint and lower thermal performance than DHVQFN - suitable for prototyping but not high-density or thermally constrained layouts. | Select when manual soldering or legacy PCB tooling limits fine-pitch QFN use. |
| 74AUP1G74GM,132 | Single D-flip-flop in ultra-small XSON6 (1.2 × 1.0 mm); 0.5 V to 3.6 V supply; 1.8 ns tpd at 3.3 V. | Half the channel count and different pinout - requires two devices for dual functionality; better for space-constrained single-channel needs. | Select when board area is critical and only one flip-flop per function is required. |
Compared with SN74LVC74APWRE4 and 74AUP1G74GM,132, the 74LVC74ABQ,115 delivers superior thermal dissipation via its exposed-pad DHVQFN package, supports dual-channel operation in minimal area (2.5 × 3.0 mm), and maintains full 5 V input tolerance - making it optimal for production-grade industrial and automotive control modules where density, reliability, and mixed-voltage compatibility are jointly prioritized.

FAQ
What is the minimum setup time (tsu) for 74LVC74ABQ,115 at 3.3 V?
The minimum setup time is 2.0 ns at VCC = 3.0 V to 3.6 V and -40 °C to +125 °C ambient. This specifies the minimum duration that data (nD) must remain stable before the LOW-to-HIGH clock transition to guarantee correct latching - verified per JEDEC JESD78 test conditions with 30 pF load and 500 Ω termination.
Can 74LVC74ABQ,115 operate reliably at 1.2 V supply?
Yes - the device is fully specified from 1.2 V to 3.6 V. At 1.2 V, propagation delay increases to ≤15 ns and maximum frequency drops to 100 MHz, but all logic functions, Schmitt-trigger input behavior, and asynchronous set/reset remain functional across -40 °C to +125 °C.
Is the exposed thermal pad on the DHVQFN package electrically connected?
No - the exposed pad (terminal 1 index area) is not electrically connected to any internal node. Per Nexperia SOT762-1 specification, it may be left unsoldered, floated, or connected to GND; no electrical requirement exists, but GND connection improves thermal performance by ~15 %.
Does 74LVC74ABQ,115 support hot insertion or live swapping?
No - the device lacks hot-swap protection circuitry. Applying VCC before or after I/O signals may cause latch-up or excessive current due to input clamping diodes. Power sequencing must follow VCC-first, then I/O, and reverse on power-down per JEDEC JESD78 guidelines.
