Product details
Overview
74LV74DB,118 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, and operation up to +125 °C - used in synchronous logic control, clock domain interfacing, and data latching in low-voltage industrial controllers.
For engineers reviewing the 74LV74DB,118 datasheet, 74LV74DB,118 pinout, 74LV74DB,118 application, or 74LV74DB,118 equivalent, key selection criteria include setup/hold timing at 1.2 V–5.5 V, propagation delay ≤13 ns (VCC = 3.3 V), asynchronous control latency ≤14 ns, and SO14 package compatibility with legacy 74-series PCB footprints.
Technical Context
This device implements two independent edge-triggered D flip-flops sharing no internal coupling - each with dedicated nD, nCP, nSD, nRD, nQ, and nQ terminals. The asynchronous nSD/nRD inputs override clocked behavior and force outputs to defined states regardless of clock state.
Input clamp diodes enable safe interfacing to voltages exceeding VCC when current-limiting resistors are used. Logic thresholds scale with VCC (VIH ≥ 0.7VCC at 4.5–5.5 V; VIL ≤ 0.3VCC), supporting direct TTL-level compatibility at 2.7–3.6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.0 V to 5.5 V - supports single-rail operation across 1.2 V logic, 1.8 V, 2.5 V, 3.3 V, and 5 V systems. |
| Propagation delay (nCP → nQ) | 13 ns max at VCC = 3.3 V, CL = 15 pF - enables reliable 60 MHz operation in synchronous designs. |
| Set-up time (nD → nCP) | 8 ns min at VCC = 3.0–3.6 V - defines minimum data stability window before clock edge for valid capture. |
| Hold time (nD → nCP) | 3 ns min at VCC = 4.5–5.5 V - constrains maximum allowable data change after clock edge. |
| Asynchronous recovery (nRD → nCP) | 6 ns min at VCC = 4.5–5.5 V - sets shortest clock-enable interval after reset deassertion. |
| Output drive strength | ±6 mA at VCC = 3.0 V (VOH/VOL guaranteed) - sufficient to drive 10 LVTTL loads or 15 pF capacitive bus. |
| Operating temperature | −40 °C to +125 °C - qualified for extended industrial and under-hood automotive-adjacent environments. |
Pinout & Package
74LV74DB,118 is supplied in SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, JEDEC MS-012 compliant.
| 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) | Data sampled on LOW-to-HIGH nCP transition - determines next-state value for corresponding nQ output. |
| 3, 11 | nCP (clock input) | Positive-edge-triggered clock - initiates sampling only on rising edge; insensitive to pulse width beyond minimum tW. |
| 4, 10 | nSD (asynchronous set) | Active-LOW direct set - forces nQ = HIGH, nQ = LOW regardless of clock or data state. |
| 5, 9 | nQ (true output) | Complementary to nQ; reflects stored data state after valid clock edge or asynchronous control assertion. |
| 6, 8 | nQ (complement output) | Inverted version of nQ; provides both polarities for combinational logic or differential signaling interfaces. |
| 7 | GND | Reference ground terminal - must be low-impedance connection to system common; decoupling capacitor required near VCC pin. |
| 14 | VCC | Primary power supply - requires local 100 nF ceramic decoupling; supports wide-range DC bias without level-shifting circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | Operates from 1.0 V to 5.5 V - eliminates need for external level shifters in mixed-voltage systems. |
| Asynchronous control | Dedicated active-LOW nSD/nRD per flip-flop - enables immediate state initialization or fault recovery without clock dependency. |
| Input clamp diodes | Integrated ESD protection diodes - permits safe interface to signals up to 7 V using series current-limiting resistors. |
| High-temperature rating | Guaranteed operation to +125 °C - suitable for industrial motor drives and power-conversion control boards. |
| Low dynamic power | CPD = 24 pF - limits switching power dissipation to <1 μW/MHz at 3.3 V, reducing thermal load in dense logic arrays. |
Applications
| Industrial PLC I/O Expansion | Legacy Bus Interface Logic |

| Motor Control State Machine | Power Sequencing Controller |
|
Use Scenario: Managing three-phase inverter gate driver enable/disable sequencing with interlocked safety states in a 12 V automotive body controller. IC Role / Device Role / Timing Role: Dual flip-flop implements lock-step state storage - one channel tracks PWM enable, the other enforces dead-time insertion via asynchronous reset coordination. Use Value: Provides hardware-enforced mutual exclusion between high-side and low-side drivers, preventing shoot-through even during software faults. |
Use Scenario: Controlling sequential power-up of multi-rail FPGA core (1.0 V), I/O (1.8 V), and auxiliary (3.3 V) supplies using a single 3.3 V supervisor signal. IC Role / Device Role / Timing Role: Edge-triggered delay element - first flip-flop captures power-good assertion, second stages it with programmable clock period to generate staggered enable pulses. Use Value: Replaces RC-based timing networks with jitter-free, temperature-stable, and repeatable sequencing intervals over −40 °C to +125 °C. |
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 | Lower VCC min (1.65 V), higher fmax (175 MHz at 3.3 V), but no 1.0–1.65 V operation. | Not suitable for sub-1.65 V systems; better for high-speed 3.3 V digital logic where speed > voltage flexibility. | Select when target system uses ≥1.65 V rails and requires >100 MHz toggle rate; avoid for battery-powered 1.2 V nodes. |
| 74AUP1G74GM | Single-channel, ultra-low power (ICC = 0.9 μA typ), smaller XSON-8 package, VCC = 0.8–3.6 V. | Requires two devices for dual functionality; lacks pin-compatible replacement for SO14 footprint. | Choose for space-constrained, ultra-low-power applications where board real estate or quiescent current dominates; not drop-in for 74LV74DB,118 layouts. |
Compared with SN74LVC74APWR and 74AUP1G74GM, the 74LV74DB,118 uniquely supports 1.0 V operation while retaining SO14 compatibility and industrial temperature range - making it optimal for legacy-replacement and wide-input-voltage embedded control.

FAQ
What is the minimum VCC required for functional operation of 74LV74DB,118?
The 74LV74DB,118 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 restricted to GND or VCC only, and timing parameters are not characterized - use 1.2 V minimum for full specification compliance.
Can 74LV74DB,118 safely interface with 5 V TTL signals without external components?
Yes - input clamp diodes allow direct connection to 5 V TTL signals when series current-limiting resistors are used. VI ratings extend to −0.5 V and +7 V, and VIH/VIL thresholds scale with VCC, enabling reliable recognition of TTL logic levels at VCC ≥ 2.7 V.
How does the asynchronous reset behave relative to the clock input?
nRD is asynchronous and active-LOW: asserting nRD forces nQ = LOW and nQ = HIGH immediately, overriding any ongoing clock activity or data state. The flip-flop remains in that state until nRD is deasserted (HIGH), after which normal clocked operation resumes on the next valid nCP edge.
Is 74LV74DB,118 qualified for automotive applications?
No - the 74LV74DB,118 is not AEC-Q100 qualified and is explicitly designated for industrial use (−40 °C to +125 °C). It lacks automotive-specific stress testing, failure analysis, and PPAP documentation; use only in non-safety-critical automotive-adjacent systems at customer's own risk.
