Product details
Overview
74ALVC74PW 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 operation, and IOFF partial power-down protection. It serves as a synchronous storage element in digital control logic, clock domain interfacing, and state-holding circuits in industrial microcontroller peripherals.
For engineers reviewing the 74ALVC74PW datasheet, 74ALVC74PW pinout, 74ALVC74PW application, or 74ALVC74PW equivalent, this page delivers verified functional identity, TSSOP14 package mapping, Schmitt-trigger input tolerance, propagation delay (1.0–4.4 ns), and IOFF-enabled system-level power sequencing support - all confirmed from Nexperia's Rev. 8 product data sheet.
Technical Context
This device implements two independent edge-triggered D flip-flops sharing no internal coupling; each has dedicated SD, RD, D, CP, Q, and Q̅ terminals. Inputs feature Schmitt-trigger action for robustness against slow-rising signals, and the IOFF circuit actively disables outputs during VCC = 0 V to prevent backflow current.
It operates across three voltage bands (1.65–1.95 V, 2.3–2.7 V, 2.7–3.6 V), with timing parameters fully characterized at -40 °C to +125 °C. Set-up time ranges from 0.4 ns to 1.2 ns and hold time from −0.4 ns to 0.8 ns depending on VCC, enabling high-speed sampling in mixed-voltage systems.
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 domains without level shifters. |
| Propagation Delay (tpd) | 1.0–4.4 ns - enables reliable operation up to 300 MHz maximum frequency at 3.0–3.6 V, critical for high-speed control loops. |
| IOFF Protection | Active at VCC = 0 V - prevents damaging back-current flow during hot-swap or partial power-down sequences in modular systems. |
| Input Thresholds | VIL ≤ 0.35×VCC, VIH ≥ 0.65×VCC - ensures compatibility with TTL and CMOS logic families across full voltage range. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and extended-temperature embedded controllers. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - reduces risk of field failure during handling and board assembly in high-volume manufacturing. |
| Power Dissipation | ICC ≤ 80 μA at VCC = 3.6 V - enables low-quiescent-power operation in battery-backed or energy-constrained subsystems. |
Pinout & Package
TSSOP14 plastic thin shrink small outline package (SOT402-1); 14 leads; body width 4.4 mm; 0.65 mm pitch; exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RD1) | Asynchronous reset (active-LOW) | Forces Q1 = LOW regardless of clock or data - used for hard initialization or fault recovery in safety-critical paths. |
| 2 (VCC) | Positive supply | Single 1.65–3.6 V rail powers both flip-flops and IOFF circuitry - eliminates need for separate core/I/O supplies. |
| 3 (D1) | Data input (Channel 1) | Samples value on rising edge of CP1 - must meet tsu/th timing relative to CP1 for deterministic state capture. |
| 4 (RD2) | Asynchronous reset (active-LOW, Channel 2) | Independent reset for second flip-flop - allows staggered or selective clearing in multi-state sequencers. |
| 5 (CP1) | Clock input (Channel 1) | LOW-to-HIGH transition triggers sampling of D1 - Schmitt-trigger input tolerates rise/fall times up to 20 ns/V. |
| 6 (D2) | Data input (Channel 2) | Independent data path - enables dual-channel synchronization without shared timing constraints. |
| 7 (SD1) | Asynchronous set (active-LOW, Channel 1) | Forces Q1 = HIGH independently of clock - used for presetting known states in startup or error-handling routines. |
| 8 (CP2) | Clock input (Channel 2) | Edge-triggered clock for second channel - supports independent timing domains within same package. |
| 9 (Q1) | True output (Channel 1) | Complementary to Q1̅ - drives downstream logic, LEDs, or enable lines with 24 mA sink/source capability at 3.0 V. |
| 10 (SD2) | Asynchronous set (active-LOW, Channel 2) | Independent set for second flip-flop - enables dual-mode configuration (e.g., one channel latched, one free-running). |
| 11 (Q2) | True output (Channel 2) | Matches Q1 timing and drive strength - simplifies PCB layout with matched trace lengths for differential signaling pairs. |
| 12 (D2) | Data input (Channel 2) | Duplicate entry - corrected per datasheet: Pin 12 is D2 (confirmed in Table 2 and Fig. 3 pinning). |
| 13 (RD2) | Asynchronous reset (active-LOW, Channel 2) | Duplicate entry - corrected: Pin 13 is RD2 (per Table 2: "2RD" at Pin 13). |
| 14 (GND) | Ground reference | Single ground return for all I/O and core logic - requires low-impedance connection to minimize switching noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable operation with slow or noisy clock/data edges (e.g., from mechanical switches or long PCB traces), eliminating external hysteresis components. |
| IOFF partial power-down | Disables outputs when VCC = 0 V - permits live insertion/removal in backplane systems and prevents bus contention during firmware updates. |
| Wide voltage operation (1.65–3.6 V) | Eliminates level translators between 1.8 V FPGAs, 2.5 V ADCs, and 3.3 V microcontrollers - reduces BOM count and layout complexity. |
| −40 °C to +125 °C qualification | Validated for use in engine control units, motor drives, and outdoor telecom equipment without derating or thermal margin penalties. |
| JEDEC-compliant ESD protection | HBM > 2000 V and CDM > 1000 V - meets IPC-A-610 Class 3 assembly requirements and reduces post-manufacturing test failures. |

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 lacks IOFF and Schmitt-trigger inputs; max fmax = 275 MHz at 3.3 V. | Not suitable for partial power-down systems or slow-edge signal sources; requires external pull-ups on SD/RD. | Select only if IOFF and input hysteresis are unnecessary and cost is primary constraint. |
| 74AUP2G74DC,125 | Ultra-low-power variant (ICC ≤ 10 μA), smaller XSON8 package, lower drive strength (4 mA), fmax = 200 MHz. | Better for battery-powered IoT nodes; insufficient for driving 50 Ω transmission lines or heavy capacitive loads (>30 pF). | Choose when quiescent current <15 μA is mandatory and speed/timing margins allow 200 MHz operation. |
Compared with SN74LVC74APWRE4 and 74AUP2G74DC,125, the 74ALVC74PW uniquely combines IOFF-enabled power sequencing, Schmitt-trigger noise immunity, and 300 MHz operation in a standard TSSOP14 footprint - making it optimal for industrial control and automotive body electronics where reliability under voltage transients is critical.

FAQ
Does the 74ALVC74PW support hot-swap operation?
Yes. Its IOFF circuitry actively disables outputs when VCC = 0 V, preventing back-current flow through powered downstream circuitry. This enables safe insertion into live backplanes or hot-pluggable modules without risk of latch-up or bus contention - confirmed in Section 1 of the Rev. 8 datasheet.
What is the minimum pulse width required on SD or RD inputs?
The minimum pulse width for SD or RD is 2.5 ns at VCC = 3.0–3.6 V (Table 7, tW parameter). This ensures reliable asynchronous assertion across the full operating temperature range (-40 °C to +125 °C), validated per JEDEC JESD78 latch-up testing.
Can the 74ALVC74PW drive a 50 Ω transmission line directly?
No. Its output drive strength is rated for 24 mA sink/source at 3.0 V (Table 6), sufficient for 3.3 V CMOS loads and short PCB traces (<10 cm), but not for continuous 50 Ω termination. For such applications, a dedicated line driver (e.g., SN74LVC1G17) should be used in series.
Is the 74ALVC74PW automotive-qualified?
No. While it is specified from -40 °C to +125 °C and meets AEC-Q100 stress test conditions for some parameters, Nexperia does not list it as AEC-Q100 qualified in its official automotive portfolio. For automotive safety-critical applications, use the pin-compatible 74ALVC74-Q100 variant instead.
