Product details
Overview
74LVC74ADB,112 from Nexperia is a dual positive-edge-triggered D-type flip-flop with asynchronous active-LOW set (nSD) and reset (nRD), 14-pin SSOP package, 1.2 V to 3.6 V supply range, and guaranteed operation from –40 °C to +125 °C - used for synchronous data latching and state storage in digital control logic, clock domain interfacing, and register file design.
For engineers reviewing the 74LVC74ADB,112 datasheet, 74LVC74ADB,112 pinout, 74LVC74ADB,112 application, or 74LVC74ADB,112 equivalent, this device supports low-voltage mixed-signal interfacing, offers Schmitt-trigger inputs for noise immunity, delivers sub-7 ns propagation delay at 3.3 V, and maintains 5 V tolerant inputs for legacy system integration.
Technical Context
The 74LVC74ADB,112 implements two independent edge-triggered D flip-flops sharing no internal coupling - each with dedicated nD, nCP, nSD, nRD, nQ, and nQ terminals. Its asynchronous nSD/nRD inputs override clock action and operate independently of nCP timing.
It uses CMOS technology with Schmitt-trigger input buffers enabling robust operation with slow-rising/falling signals, and supports JEDEC-compliant voltage interfaces across 1.2–3.6 V supply rails while maintaining TTL-level compatibility and 5 V input tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - enables direct use in battery-powered, low-power, and multi-rail embedded systems without level-shifting. |
| Propagation Delay (tpd) | 1.0 ns (min) to 6.5 ns (max) at VCC = 3.0–3.6 V - ensures reliable timing closure in high-speed digital control paths up to 120 MHz. |
| Set-up Time (tsu) | 2.0 ns (max) at VCC = 3.0–3.6 V - defines minimum stable window for nD before nCP rising edge to guarantee deterministic state capture. |
| Hold Time (th) | +1.0 ns (max) at VCC = 3.0–3.6 V - specifies minimum time nD must remain stable after nCP rising edge to prevent metastability. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple LVC/LVT inputs or small capacitive loads without external buffering. |
| Input Voltage Tolerance | 0 V to 5.5 V - allows safe connection to 5 V logic outputs without clamping diodes or external protection. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLCs, and extended-temperature power management controllers. |
Pinout & Package
74LVC74ADB,112 is supplied in a 14-lead SSOP package (SOT337-1), body width 5.3 mm, pitch 0.65 mm, with exposed pad not electrically connected. Pin 1 is marked by a notch or index area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1RD, 2RD | Asynchronous Reset (active LOW) | Forces nQ = LOW regardless of clock or data - used for power-on initialization or fault recovery. |
| 1D, 2D | Data Input | Samples value on LOW-to-HIGH nCP transition - determines next-state output for corresponding flip-flop. |
| 1CP, 2CP | Clock Input (edge-triggered) | Positive-edge sensitive; triggers state update only on rising edge - eliminates race conditions in synchronous logic. |
| 1SD, 2SD | Asynchronous Set (active LOW) | Forces nQ = HIGH regardless of clock or data - enables immediate assertion of control flags or status bits. |
| 1Q, 2Q | True Output | Complements nD state after nCP edge - drives downstream logic, LEDs, or bus lines with rail-to-rail swing. |
| 1Q, 2Q | Inverted Output | Logic complement of nQ - supports differential signaling, enable/disable pairing, or complementary latch feedback. |
| GND | Ground Reference | 0 V reference for all I/O and internal circuitry - requires low-impedance PCB connection to minimize ground bounce. |
| VCC | Supply Voltage | Primary power rail - decoupling capacitor (100 nF) recommended within 5 mm of pin for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant inputs | Enables direct interface with legacy 5 V microcontrollers, FPGAs, or ASICs without level translators. |
| Schmitt-trigger inputs | Provides >0.5 V hysteresis per input - rejects noise on slow-switching control lines (e.g., pushbuttons, sensors). |
| Wide supply range (1.2–3.6 V) | Supports single-supply operation across Li-ion (3.3 V), coin-cell (1.8 V), and ultra-low-power MCU domains. |
| 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 in multi-vendor designs. |
| ESD protection (HBM/CDE) | HBM >2000 V and CDM >1000 V - reduces need for external ESD protection in handheld or field-deployable equipment. |
Applications
| Industrial Motor Control | Digital Power Sequencing |

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 | Same logic function and pinout (TSSOP14), but rated only to +85 °C ambient and lacks DHVQFN/DHXQFN variants. | Preferred for commercial-grade instrumentation where extended temperature is unnecessary and board space permits larger TSSOP footprint. | Select when cost sensitivity outweighs thermal margin and SSOP-specific layout constraints apply. |
| 74AUP2G74DC,125 | Ultra-low-power AUP family; 0.8–3.6 V supply, 1.4 μA ICC (typ), but slower max frequency (200 MHz vs 250 MHz at 3.3 V) and no 5 V tolerance. | Better suited for always-on sensor nodes or energy-harvesting systems where quiescent current dominates timing budget. | Choose only if supply voltage drops below 1.2 V or sub-μA sleep current is mandatory - not drop-in compatible for 5 V interfacing. |
Compared with SN74LVC74APWRE4 and 74AUP2G74DC,125, the 74LVC74ADB,112 uniquely combines 5 V input tolerance, –40 °C to +125 °C operation, and SSOP packaging - making it optimal for automotive and industrial control where signal integrity, thermal resilience, and legacy interface coexist.

FAQ
Is the 74LVC74ADB,112 pin-compatible with standard 74LVC74A variants?
Yes - the 74LVC74ADB,112 uses the same 14-pin SSOP (SOT337-1) pinout defined in the base 74LVC74A specification, including identical terminal assignments for 1RD, 1D, 1CP, 1SD, 1Q, 1Q, GND, VCC, 2Q, 2Q, 2SD, 2CP, 2D, and 2RD. No layout changes are needed when substituting within the same package variant.
What is the maximum clock frequency supported at 1.8 V supply?
At VCC = 1.8 V (within JESD8-7A range), the 74LVC74ADB,112 supports a maximum clock frequency of 100 MHz, as specified in Table 8 for VCC = 1.65 V to 1.95 V. This is validated across –40 °C to +125 °C and accounts for worst-case propagation delay and pulse width requirements.
Does the SSOP package include thermal enhancement features?
No - unlike the DHVQFN14 (SOT762-1) or DHXQFN14 (SOT8014-1) variants, the SOT337-1 SSOP package has no exposed thermal pad or enhanced thermal dissipation path. Its Ptot rating is 500 mW at Tamb ≤ 100 °C, derating linearly above that per datasheet Section 7.
Can the 74LVC74ADB,112 be used with 5 V microcontroller GPIOs driving its inputs?
Yes - all inputs are 5 V tolerant up to 5.5 V, allowing direct connection to 5 V GPIOs without series resistors or level shifters. The device operates correctly with VI = 5.5 V while powered from 1.2–3.6 V, and input leakage remains within ±20 μA per datasheet Table 9.
