Product details
Overview
74ALVC74PW-Q100 from Nexperia is a dual positive-edge-triggered D-type flip-flop with asynchronous set (active-LOW) and reset (active-LOW), 14-pin TSSOP package, 1.65 V to 3.6 V supply range, and AEC-Q100 Grade 1 qualification for automotive use. It stores data on LOW-to-HIGH clock transitions, features Schmitt-trigger inputs for noise immunity, and includes IOFF circuitry for partial power-down protection.
For engineers reviewing the 74ALVC74PW-Q100 datasheet, 74ALVC74PW-Q100 pinout, 74ALVC74PW-Q100 application, or 74ALVC74PW-Q100 equivalent, key selection criteria include propagation delay (≤4.4 ns at 3.6 V), setup/hold timing (tsu = 0.8 ns, th = −0.1 ns), wide temperature range (−40 °C to +125 °C), and automotive-grade reliability under ISO/TS 16949-aligned manufacturing.
Technical Context
This device implements two independent edge-triggered D-flip-flops in a single IC, each with dedicated D, CP, SD, RD, Q, and Q̅ terminals. Its Schmitt-trigger inputs tolerate slow signal edges, and the IOFF feature disables outputs during power-down to prevent backflow current when VCC = 0 V.
It operates across three voltage bands-1.65–1.95 V, 2.3–2.7 V, and 2.7–3.6 V-with corresponding VIH/VIL thresholds and dynamic performance scaling. The function table confirms priority of asynchronous controls (SD/RD over clocked D), and all timing parameters are specified with defined measurement conditions per JEDEC test standards.
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) | ≤4.4 ns at VCC = 3.0–3.6 V - enables reliable operation up to 300 MHz maximum clock frequency. |
| Set-up Time (tsu) | 0.8 ns at VCC = 3.0–3.6 V - defines minimum D-input stability window before clock edge for deterministic sampling. |
| Hold Time (th) | −0.1 ns at VCC = 3.0–3.6 V - allows D-input to change up to 0.1 ns after clock edge without metastability risk. |
| IOFF Leakage | ±80 μA at VI/VO = 3.6 V, VCC = GND - ensures safe bus isolation during hot-swap or partial power-down sequences. |
| Operating Temperature | −40 °C to +125 °C - qualified for engine bay, ADAS sensor modules, and powertrain control units. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive system-level ESD robustness requirements per ISO 10605. |
Pinout & Package
TSSOP14 (SOT402-1) plastic thin shrink small outline package, 14 leads, body width 4.4 mm, 0.65 mm pitch, lead finish matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1RD, 13RD | Asynchronous reset (active-LOW) | Forces Q = L, Q̅ = H independently of clock; overrides D input and CP edge. |
| 1SD, 4SD, 10SD | Asynchronous set (active-LOW) | Forces Q = H, Q̅ = L independently of clock; higher priority than D but lower than RD per function table. |
| 1CP, 3CP, 11CP | Clock input (LOW-to-HIGH edge-triggered) | Samples D input only on rising edge; Schmitt trigger ensures clean edge detection despite slow slew rates. |
| 1D, 2D, 12D | Data input | Held stable during tsu/th window around CP edge; determines next-state Q output on valid clock transition. |
| 1Q, 5Q, 9Q, 2Q | True output | Complementary to Q̅; drives downstream logic with CMOS-compatible VOH/VOL levels across full VCC range. |
| 1Q, 6Q, 8Q, 2Q | Complement output | Provides inverted state for differential signaling, feedback paths, or dual-rail logic interfaces. |
| VCC (14) | Supply voltage | Power rail for both flip-flops; must be decoupled locally due to fast switching transients (CPD = 35 pF). |
| GND (7) | Ground reference | Common return path for all I/O and internal logic; requires low-inductance connection to minimize ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive applications operating from −40 °C to +125 °C ambient, including thermal cycling and HTOL stress testing. |
| IOFF partial power-down mode | Outputs enter high-impedance state when VCC = 0 V, preventing destructive back-current through powered subsystems during sequencing faults. |
| Schmitt-trigger inputs | Input hysteresis ≥0.3 V typical enables reliable operation with noisy or slow-rising signals (e.g., from sensors or long PCB traces). |
| Overvoltage-tolerant inputs | Accepts up to 3.6 V input signals even when VCC = 1.65 V - eliminates need for external clamping diodes in mixed-voltage systems. |
| Direct TTL interface capability | VIH ≤ 2.0 V and VOL ≤ 0.45 V at 3.0 V VCC ensure compatibility with legacy 5 V TTL outputs via pull-up resistors or level translators. |
Applications

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 | Non-automotive grade; rated −40 °C to +125 °C but not AEC-Q100 qualified; identical pinout and AC specs. | Lacks automotive qualification documentation and production traceability; unsuitable for safety-critical ECUs. | Select only for non-automotive industrial or consumer prototypes where cost is prioritized over qualification. |
| 74LVC74ABQ-Q100 | Same functionality in 14-pin DHVQFN package (SOT764); 0.5 mm pitch, exposed thermal pad, better thermal resistance. | Requires different PCB layout and reflow profile; superior thermal performance for high-density ADAS modules. | Choose when board space is constrained or junction temperature rise exceeds 85 °C in continuous operation. |
Compared with SN74LVC74APWRE4, the 74ALVC74PW-Q100 adds AEC-Q100 documentation and process controls essential for Tier 1 automotive sourcing; versus 74LVC74ABQ-Q100, it trades thermal efficiency for legacy TSSOP assembly compatibility and lower rework cost.

FAQ
What is the maximum clock frequency supported by the 74ALVC74PW-Q100?
The device supports up to 300 MHz maximum clock frequency at VCC = 3.0 V to 3.6 V, verified by fmax testing per JEDEC JESD66. This value assumes proper PCB layout, 30–50 pF load capacitance, and 2.5 ns input rise/fall times. At lower voltages (e.g., 1.65 V), fmax drops to 150 MHz due to reduced drive strength.
Does the 74ALVC74PW-Q100 require external pull-up resistors on its set/reset inputs?
No external pull-ups are required: the SD and RD inputs have integrated weak pull-downs (typical 100 kΩ) ensuring defined LOW states when unconnected. However, for noise immunity in high-EMI environments like engine compartments, 10 kΩ external pull-downs are recommended to reinforce active-LOW assertion.
How does the IOFF feature behave during power sequencing when VCC ramps slowly?
IOFF activates when VCC falls below ~0.8 V, forcing outputs into high-impedance state before supply collapse. During ramp-up, outputs remain disabled until VCC exceeds 1.0 V, preventing glitch generation. This behavior is guaranteed across −40 °C to +125 °C and validated per AEC-Q100 stress tests.
Can the 74ALVC74PW-Q100 interface directly with 5 V TTL outputs?
Yes - its overvoltage-tolerant inputs accept 5 V signals up to 3.6 V regardless of VCC level. When VCC = 3.3 V, VIH = 2.0 V and VOL = 0.45 V meet TTL output thresholds, enabling direct connection without level shifters. For sustained 5 V input exposure, series 100 Ω resistors are advised to limit current during fault conditions.
