Product details
Overview
74ALVC74PW,118 from Nexperia is a dual positive-edge-triggered D-type flip-flop with independent asynchronous set (SD) and reset (RD) inputs, complementary Q/Q̅ outputs per channel, 1.65 V to 3.6 V supply range, −40 °C to +125 °C operating temperature, and IOFF partial power-down protection. It serves as a synchronous storage element in clock-domain crossing, data latching, and state-holding circuits in industrial control logic and low-voltage digital interfaces.
For engineers reviewing the 74ALVC74PW,118 datasheet, 74ALVC74PW,118 pinout, 74ALVC74PW,118 application, or 74ALVC74PW,118 equivalent, this page delivers verified functional behavior, TSSOP14 package mapping, propagation delay (≤4.4 ns at 3.6 V), set-up/hold timing (tsu = 0.8 ns, th = 0.8 ns), and IOFF-enabled power sequencing compatibility for mixed-supply systems.
Technical Context
This device implements two independent edge-triggered D flip-flops sharing no internal coupling-each with dedicated D, CP, SD, RD, Q, and Q̅ terminals. Clocking is strictly positive-edge (LOW-to-HIGH transition), and asynchronous controls override clocked behavior with active-LOW assertion.
Schmitt-trigger inputs tolerate slow-rising/falling signals (Δt/ΔV ≤10 ns/V at 3.6 V), while the IOFF circuit disables outputs when VCC = 0 V, blocking backflow current during partial power-down-a critical feature for hot-swap and multi-rail system designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.65 V to 3.6 V - supports direct interface with 1.8 V, 2.5 V, and 3.3 V logic families without level shifters |
| Propagation delay (tpd) | 1.0–4.4 ns - ensures sub-5 ns timing margin for 100+ MHz synchronous logic in industrial PLCs |
| Set-up / hold time | tsu = 0.8 ns, th = 0.8 ns at VCC = 3.6 V - enables reliable capture of fast data edges adjacent to clock transitions |
| IOFF leakage | ±10 μA max at VCC = GND - prevents destructive back-current during power sequencing in mixed-voltage boards |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives |
| ESD robustness | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events without latch-up or parametric shift |
| Power dissipation capacitance | CPD = 35 pF - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal budgeting |
Pinout & Package
TSSOP14 package (SOT402-1): 4.4 mm body width, 0.65 mm lead pitch, 14-terminal surface-mount plastic thin shrink small outline package optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 | 1RD / 2RD | Asynchronous active-LOW reset - forces Q = L, Q̅ = H independently per flip-flop, overriding clock |
| 2, 14 | VCC / GND | Supply rail and ground reference - decoupling capacitor placement near Pin 2 and Pin 7 is mandatory for noise immunity |
| 3, 12 | 1D / 2D | Data input - sampled on rising clock edge if set-up/hold times are met; Schmitt-triggered for slow-edge tolerance |
| 4, 10 | 1SD / 2SD | Asynchronous active-LOW set - forces Q = H, Q̅ = L independently per flip-flop, overriding clock |
| 5, 11 | 1CP / 2CP | Clock input - LOW-to-HIGH transition triggers synchronous data capture; Schmitt-triggered |
| 6, 9 | 1Q / 2Q | True output - reflects stored D value after clock edge; drives standard CMOS loads up to ±24 mA |
| 7, 8 | 1Q̅ / 2Q̅ | Complement output - inverted copy of Q; enables direct implementation of toggle or JK-like behavior |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 1.65–3.6 V operation eliminates need for separate voltage rails in mixed-logic systems |
| IOFF partial power-down | Output disable at VCC = 0 V prevents back-current damage during hot-swap or staged power sequencing |
| Schmitt-trigger inputs | Input hysteresis enables reliable operation with slow-rising clocks or noisy control signals (e.g., mechanical switch debouncing) |
| Overvoltage-tolerant inputs | Accepts up to 3.6 V inputs regardless of VCC - allows interfacing with higher-voltage peripherals without external clamping |
| Latch-up immunity | Exceeds 250 mA per JESD78 Class II.A - ensures robustness against transient overcurrent events in industrial environments |
Applications
| Industrial PLC I/O Expansion | Digital Power Supply Sequencing |
|---|---|
Use Scenario: Storing enable states for multiple isolated DC-DC converter rails during cold-start and fault recovery. IC Role / Device Role / Timing Role: Dual flip-flop holds synchronized ON/OFF commands across two independent power domains, triggered by a centralized sequencer clock. Use Value: Ensures deterministic turn-on order and prevents shoot-through by guaranteeing simultaneous, edge-aligned activation of gate drivers. |
Use Scenario: Capturing and holding status bits from analog monitoring ICs (e.g., voltage/current faults) in telecom rectifier modules. IC Role / Device Role / Timing Role: Latches fault flags on rising edge of system watchdog timer pulse, preserving state across microcontroller resets. Use Value: Maintains fault history across power cycles without non-volatile memory, reducing BOM cost and firmware complexity. |
| Automotive Body Control Module | Test Equipment Digital Pattern Generation |
Use Scenario: Debouncing door lock/unlock switch inputs and synchronizing them to CAN message transmission timing. IC Role / Device Role / Timing Role: Uses Schmitt-triggered inputs to suppress contact bounce, then clocks clean signals into MCU GPIO via synchronized Q outputs. Use Value: Eliminates software debounce routines, freeing MCU cycles and ensuring sub-millisecond response consistency across vehicle variants. |
Use Scenario: Generating precise, phase-aligned stimulus waveforms for validating high-speed ADC/DAC timing margins. IC Role / Device Role / Timing Role: Two flip-flops produce complementary clock-divided patterns (e.g., Q1 = CLK/2, Q2 = CLK/4) with matched propagation paths. Use Value: Delivers <5 ns skew between related outputs, enabling accurate setup/hold validation at 200+ MHz test frequencies. |
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 TSSOP14 package, but only rated −40 °C to +85 °C; no IOFF circuitry; slightly higher tpd (5.5 ns max at 3.3 V) | Lacks partial power-down support; unsuitable for hot-swap or multi-rail sequencing where VCC may be unpowered | Select only for cost-sensitive commercial-grade applications with single-rail operation and ambient-limited environments |
| 74LVC2G74DP,125 | Single-channel version in ultra-small XSON8 (2 × 1.35 mm); identical VCC range and IOFF, but half the functionality per package | Requires two devices for dual-channel use; increases layout area and routing complexity versus one 74ALVC74PW | Prefer when board space is constrained and channels operate independently with different timing requirements |
Compared with SN74LVC74APWRE4 and 74LVC2G74DP,125, the 74ALVC74PW,118 uniquely combines dual-channel density, full −40 °C to +125 °C qualification, and IOFF protection-making it the only choice for thermally demanding, multi-rail industrial controllers requiring guaranteed power sequencing integrity.

FAQ
Does 74ALVC74PW,118 support mixed-voltage interfacing?
Yes. Its overvoltage-tolerant inputs accept up to 3.6 V regardless of VCC (1.65–3.6 V), enabling direct connection to 3.3 V or 5 V peripherals without level shifters. Output VOH/VOL specs align with standard CMOS thresholds across the full supply range, ensuring interoperability with LVC, ALVC, and older 74HC families.
How does the IOFF feature behave during power sequencing?
When VCC drops to 0 V, the IOFF circuit actively disables all outputs (Q and Q̅), presenting high-impedance states. This prevents backflow current from powered downstream logic into the unpowered flip-flop-critical for safe hot-plug operation and staggered power-up sequences in multi-rail systems.
Can both flip-flops operate independently with different clocks?
Yes. The 74ALVC74PW,118 contains two fully isolated D-type flip-flops: FF1 uses Pins 1RD, 1D, 1CP, 1SD, 1Q, 1Q̅; FF2 uses Pins 2RD, 2D, 2CP, 2SD, 2Q, 2Q̅. There is no shared internal path-each channel responds only to its own control and data signals, supporting asynchronous dual-clock domains.
What is the minimum pulse width required on SD/RD inputs for reliable assertion?
The minimum pulse width for asynchronous set/reset is 2.5 ns (tW) across all VCC conditions. At VCC = 3.6 V, typical tW is 0.7 ns, but design must guarantee ≥2.5 ns to ensure metastability-free state forcing-even under worst-case process/voltage/temperature corners.
