Product details
Overview
74LVC74AD,118 from Nexperia is a dual positive-edge-triggered D-type flip-flop with asynchronous active-LOW set (nSD) and reset (nRD), 14-pin SO14 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 digital control logic, bus interface timing, and clock-domain synchronization.
For engineers reviewing the 74LVC74AD,118 datasheet, 74LVC74AD,118 pinout, 74LVC74AD,118 application, or 74LVC74AD,118 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 reliable edge-triggered behavior across industrial temperature extremes.
Technical Context
This dual D-flip-flop implements two independent edge-triggered storage cells sharing no internal coupling - each features separate D, CP, SD, RD, Q, and Q̅ terminals. The asynchronous set/reset override clock action and operate independently of nCP transitions.
Input Schmitt triggers provide hysteresis (typ. 0.3 V at 3.3 V), enabling robust handling of slow-rising signals; output drive strength is specified at ±24 mA (VOH/VOL) under defined load conditions, supporting direct TTL-level interfacing without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.2 V to 3.6 V - enables interoperability with 1.8 V, 2.5 V, and 3.3 V logic domains without external level shifters. |
| Propagation Delay (tpd) | 1.0 ns to 6.5 ns (VCC = 3.0–3.6 V) - ensures tight timing margins in high-speed synchronous logic chains. |
| Maximum Clock Frequency | 150 MHz (min) at VCC = 3.0–3.6 V - supports real-time sampling and control loop update rates up to 150 million cycles per second. |
| Set-up/Hold Time (tsu/th) | 2.0 ns / +1.0 ns (VCC = 3.0–3.6 V) - defines minimum data stability window before and after clock edge for deterministic state capture. |
| ESD Protection | HBM >2000 V, CDM >1000 V - provides built-in resilience against handling-induced electrostatic discharge during PCB assembly. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and extended-range power management systems. |
| Power Dissipation Capacitance | CPD = 19.1 pF (VCC = 3.3 V) - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal budgeting. |
Pinout & Package
74LVC74AD,118 uses the SOT108-1 (SO14) plastic small outline package: 14-lead, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, JEDEC MS-012 compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 | nRD (asynchronous reset) | Active-LOW direct reset input - forces nQ = LOW regardless of clock or data; overrides all other inputs. |
| 2, 12 | nD (data input) | Primary synchronous data source - value sampled on LOW-to-HIGH clock transition and transferred to nQ. |
| 3, 11 | nCP (clock input) | Positive-edge-triggered clock - initiates data capture only on rising edge; Schmitt-triggered for noise rejection. |
| 4, 10 | nSD (asynchronous set) | Active-LOW direct set input - forces nQ = HIGH regardless of clock or data; independent of nRD. |
| 5, 9 | nQ (true output) | Complementary logic state of stored data - drives downstream logic with CMOS-compatible voltage levels. |
| 6, 8 | nQ̅ (complement output) | Inverted output - eliminates need for external inverters in toggle or differential signaling paths. |
| 7 | GND | Reference ground terminal - must be connected to system 0 V plane for stable bias and noise control. |
| 14 | VCC | Primary supply rail - powers both flip-flop sections; decoupling capacitor (100 nF) recommended within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant inputs | Accepts 0–5.5 V input signals while powered from 1.2–3.6 V - enables seamless bridging between legacy 5 V and modern low-voltage subsystems. |
| Schmitt-trigger inputs | Input hysteresis ≥0.3 V at 3.3 V - suppresses false triggering from noisy or slowly transitioning control lines (e.g., mechanical switch debouncing). |
| Wide temperature range | Specified from −40 °C to +125 °C - supports deployment in engine control units, motor drives, and outdoor telecom infrastructure without derating. |
| Low static current | ICC ≤ 40 μA at VCC = 3.6 V - minimizes quiescent power in always-on monitoring circuits and battery-backed state retention. |
| JEDEC-compliant interfaces | 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-supply SoC designs. |
Applications
| Industrial PLC Input Latching | USB Interface Glitch Filtering |
|---|---|
|
Use Scenario: Capturing momentary sensor actuations (e.g., limit switches, emergency stops) into a deterministic register for scan-cycle processing. IC Role / Device Role / Timing Role: Dual D-flip-flop acts as synchronized input synchronizer - samples raw GPIO signals on system clock edge and holds stable values for firmware polling. Use Value: Eliminates metastability risk in microcontroller GPIO reads by providing two-stage synchronization with guaranteed setup/hold compliance at 125 °C. |
Use Scenario: Conditioning USB VBUS detect and ID pin signals before routing to USB controller to suppress contact bounce and EMI transients. IC Role / Device Role / Timing Role: Edge-triggered latch captures clean logic states from noisy board-level traces, using Schmitt-trigger inputs to reject sub-10 ns glitches. Use Value: Prevents false USB enumeration events caused by connector mating noise - achieves >99.9% signal integrity without external RC filters. |
| Digital Audio Clock Domain Crossing | Motor Control PWM Synchronization |
|
Use Scenario: Aligning I²S frame sync pulses (WS) from audio codec to local MCU clock domain for precise sample buffer management. IC Role / Device Role / Timing Role: Asynchronous set/reset enables forced alignment of Q outputs to known states prior to domain transfer initiation. Use Value: Guarantees zero-cycle misalignment during audio stream start/stop - prevents pop/click artifacts in Class-D amplifier outputs. |
Use Scenario: Synchronizing enable/disable commands from safety monitor IC to half-bridge gate drivers in BLDC motor controllers. IC Role / Device Role / Timing Role: Dual latch stores fault-clear and run-enable bits; complementary Q/Q̅ outputs drive isolated gate driver inputs with matched propagation delays. Use Value: Ensures <1.5 ns skew between high-side and low-side enable paths - critical for preventing shoot-through in 100 kHz PWM stages. |
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); 0.65 mm pitch; 4.4 mm body width; identical electrical specs and pinout mapping. | Better thermal resistance (7.3 mW/K derating above 81 °C) but lower moisture sensitivity level (MSL3 vs MSL1 for SO14). | Select for space-constrained PCBs requiring finer pitch; verify reflow profile compatibility due to thinner leadframe. |
| 74AUP2G74DC,125 | Ultra-low-power AUP family; VCC = 0.8–3.6 V; ICC = 0.9 μA typical; tpd = 11.9 ns @ 1.2 V - slower but 10× lower static current. | Targeted for battery-powered IoT nodes; not rated for +125 °C operation (max +85 °C only). | Choose when energy efficiency dominates speed requirements and ambient temperature stays below 85 °C. |

FAQ
Can 74LVC74AD,118 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 (max), fmax drops to 100 MHz, and VIH/VIL thresholds scale proportionally (VIH = 1.08 V min). All functionality remains guaranteed across −40 °C to +125 °C at this voltage.
What is the purpose of the Schmitt-trigger inputs?
Schmitt-trigger inputs provide hysteresis (typically 0.3 V at 3.3 V), allowing the device to cleanly interpret slow-rising or noisy signals - such as those from mechanical switches, long PCB traces, or unfiltered sensors - without multiple transitions or metastability during threshold crossing.
How does the asynchronous reset differ from synchronous reset behavior?
Asynchronous reset (nRD) forces nQ LOW immediately upon assertion, independent of clock edge timing - critical for fail-safe initialization. Synchronous reset would require a clock edge to take effect, introducing latency and potential race conditions during power-up or fault recovery sequences.
Is 74LVC74AD,118 pin-compatible with older 74HC74 variants?
No - while functionally similar, 74LVC74AD,118 uses different input threshold voltages (VIH = 0.65×VCC vs HC's fixed 3.5 V), higher speed, and lower drive strength. Direct substitution may cause timing violations or logic level mismatches in 5 V systems unless VCC and interface voltages are verified.
