Product details
Overview
74LV74DB,112 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 industrial microcontroller peripherals.
For engineers reviewing the 74LV74DB,112 datasheet, 74LV74DB,112 pinout, 74LV74DB,112 application, or 74LV74DB,112 equivalent, key selection criteria include propagation delay at 3.3 V (11 ns), setup/hold times (8 ns / 3 ns), wide VCC tolerance (1.0–5.5 V), and SO14 package compatibility with legacy 74-series board layouts.
Technical Context
This device implements two independent edge-triggered D flip-flops sharing no internal coupling; each has dedicated nD, nCP, nSD, nRD, nQ, and nQ terminals. The asynchronous nSD/nRD inputs override clocked behavior and assert active-LOW logic, enabling immediate state initialization without clock dependency.
Designed for low-voltage CMOS systems, it supports direct TTL-level interfacing (2.7–3.6 V), includes input clamp diodes for overvoltage protection, and meets JESD 78 Class II Level B latch-up immunity (>100 mA). Its dynamic performance is characterized across VCC = 1.2 V to 5.5 V with defined timing at -40 °C to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage (VCC) | 1.0 V to 5.5 V - enables interoperability with 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| Propagation delay (tpd) | 11 ns at VCC = 3.3 V, CL = 15 pF - determines maximum synchronous data path timing margin |
| Maximum clock frequency (fmax) | 100 MHz at VCC = 3.3 V - sets upper bound for reliable toggle rate in counter or register applications |
| Setup/hold time (tsu/th) | 8 ns / 3 ns at VCC = 3.3 V - defines minimum data stability window before and after clock edge |
| Operating temperature | -40 °C to +125 °C - qualified for extended industrial and under-hood automotive-adjacent environments |
| Input clamp diodes | Integrated - allows safe interface to signals exceeding VCC when used with current-limiting resistors |
| ESD protection | HBM >2000 V, CDM >1000 V - reduces risk of handling damage during PCB assembly |
Pinout & Package
74LV74DB,112 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 (1RD, 2RD) | Asynchronous reset (active-LOW) | Forces corresponding Q output LOW independently of clock; overrides stored state immediately |
| 2, 12 (1D, 2D) | Data input | Samples and stores logic level on rising clock edge; defines next-state value for that flip-flop |
| 3, 11 (1CP, 2CP) | Clock input (LOW-to-HIGH edge) | Triggers storage of D-input value; edge sensitivity eliminates metastability from slow transitions |
| 4, 10 (1SD, 2SD) | Asynchronous set (active-LOW) | Forces corresponding Q output HIGH independently of clock; enables immediate initialization |
| 5, 9 (1Q, 2Q) | True output | Reflects stored D-value after clock edge; drives downstream logic or bus lines |
| 6, 8 (1Q, 2Q) | Complement output | Provides inverted logic state; eliminates need for external inverters in toggle or feedback paths |
| 7 | GND | Reference 0 V return path for all internal circuitry and I/O |
| 14 | VCC | Primary power supply rail; powers both flip-flop channels and input/output buffers |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.0–5.5 V) | Supports mixed-voltage system integration without level shifters in 1.2 V–5 V domains |
| Asynchronous set/reset per channel | Enables deterministic startup, error recovery, or forced state alignment without clock synchronization |
| CMOS low-power dissipation | ICC ≤ 20 μA typical at VCC = 5.5 V - reduces static power in always-on control logic |
| Input clamp diodes | Permits robust interfacing to higher-voltage sources (e.g., 5 V MCU GPIO driving 3.3 V logic) using series resistors |
| Industrial temperature grade (-40 °C to +125 °C) | Validated operation in harsh thermal environments such as motor drives, PLC I/O modules, and power supplies |
Applications
| Industrial PLC Input Latching | Microcontroller Peripheral Synchronization |
|---|---|
|
Use Scenario: Capturing momentary sensor or switch inputs in programmable logic controllers where signal bounce or noise must be filtered via clocked sampling. IC Role / Device Role / Timing Role: Dual D flip-flop acts as synchronized input register, debouncing mechanical contacts by sampling at system clock edges. Use Value: Eliminates metastability and contact chatter effects; ensures deterministic state capture aligned to CPU instruction cycle boundaries. |
Use Scenario: Aligning asynchronous peripheral status flags (e.g., UART TX ready, ADC conversion complete) to a microcontroller's internal clock domain. IC Role / Device Role / Timing Role: Provides two-stage synchronizer (using cascaded flip-flops) or isolated edge detection for interrupt generation. Use Value: Prevents timing violations and false interrupts caused by asynchronous signal arrival; enables safe flag sampling without CPU polling overhead. |
| Digital Logic State Machine Control | Legacy 74-Series Board Replacement |
|
Use Scenario: Implementing finite-state machine (FSM) control logic in cost-sensitive industrial timers, sequencers, or lighting controllers. IC Role / Device Role / Timing Role: Stores current FSM state bits and updates on clock edge based on combinational next-state logic. Use Value: Delivers predictable, glitch-free state transitions with minimal external components; replaces discrete gate-based latches. |
Use Scenario: Upgrading aging 74HC74 or 74LS74 designs requiring lower power, wider supply range, or extended temperature support. IC Role / Device Role / Timing Role: Pin- and function-compatible drop-in replacement for legacy dual D flip-flops in existing SO14 footprints. Use Value: Maintains board layout while improving power efficiency, noise immunity, and operating range without redesign effort. |
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 |
|---|---|---|---|
| 74LVC74AD,118 | Lower VCC min (1.65 V), higher fmax (200 MHz at 3.3 V), but no 1.0–1.65 V operation | Better suited for high-speed 3.3 V systems; not usable below 1.65 V | Select when speed >100 MHz is required and supply is ≥1.65 V |
| SN74LV74APWR | TSSOP14 package (SOT402-1), identical electrical specs, same -40 °C to +125 °C rating | Smaller footprint and higher density; requires rework for SO14-only boards | Select for space-constrained PCBs where TSSOP assembly is supported |
Compared with 74LVC74AD,118 and SN74LV74APWR, the 74LV74DB,112 uniquely supports 1.0 V operation and retains SO14 compatibility - making it optimal for ultra-low-voltage legacy upgrades and industrial boards with fixed through-hole or SOIC land patterns.

FAQ
What is the minimum supply voltage for guaranteed operation of the 74LV74DB,112?
The 74LV74DB,112 is fully functional down to VCC = 1.0 V, with DC characteristics guaranteed from 1.2 V to 5.5 V. At 1.0 V, it supports basic logic operation (HIGH/LOW interpretation), though timing parameters are specified starting at 1.2 V per the datasheet's static characteristics table.
Can the 74LV74DB,112 drive standard 5 V TTL inputs directly?
Yes - the 74LV74DB,112 provides VOH ≥ 2.4 V at VCC = 3.0 V with 6 mA load, meeting TTL VIH minimum (2.0 V). Its outputs are compatible with 5 V TTL inputs when VCC ≥ 2.7 V, eliminating need for external level shifters in mixed-voltage interfaces.
How does the asynchronous reset behave relative to the clock input?
The asynchronous reset (nRD) forces the corresponding Q output LOW immediately upon assertion (LOW), regardless of clock state or edge. It overrides all clocked behavior and holds Q LOW until nRD returns HIGH - enabling immediate, clock-independent state clearing.
Is the 74LV74DB,112 suitable for automotive applications?
No - the 74LV74DB,112 is not AEC-Q100 qualified and is explicitly designated for industrial use (-40 °C to +125 °C). Nexperia states non-automotive qualified products are unsuitable for safety-critical or life-support systems; automotive deployment requires explicit qualification and validation by the customer.
