Product details
Overview
74LVC574APW-Q100 from Nexperia is an automotive-grade octal D-type flip-flop with positive-edge clock triggering, 3-state outputs, 5 V tolerant I/O (up to 5.5 V), and IOFF partial power-down protection. It operates from 1.2 V to 3.6 V supply, supports mixed-voltage interfacing between 3.3 V and 5 V systems, and is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C).
For engineers reviewing the 74LVC574APW-Q100 datasheet, 74LVC574APW-Q100 pinout, 74LVC574APW-Q100 application, or 74LVC574APW-Q100 equivalent, key selection considerations include its 3-state bus-hold capability, Schmitt-trigger inputs for noise immunity, tpd ≤ 7.0 ns at 3.3 V, IOFF-enabled safe power sequencing, and TSSOP20 package compatibility with high-density PCB layouts.
Technical Context
This device implements eight independent edge-triggered D flip-flops sharing a common clock (CP) and output enable (OE) control. Each flip-flop captures Dn input state on the LOW-to-HIGH CP transition, with set-up time as low as 2.0 ns and hold time of +1.5 ns at 3.3 V.
The 3-state output buffer is fully decoupled from register operation: OE assertion disables outputs without altering stored data, and IOFF circuitry blocks backflow current when VCC = 0 V - enabling hot-swap and partial power-down system architectures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.2 V to 3.6 V - enables direct interface with 1.8 V, 2.5 V, and 3.3 V logic domains |
| Input tolerance | Up to 5.5 V - allows connection to 5 V buses without level shifters in mixed-voltage systems |
| Propagation delay (tpd) | ≤ 7.0 ns at VCC = 3.3 V - supports >120 MHz clock rates in synchronous bus applications |
| IOFF leakage | ≤ ±20 μA at VCC = 0 V - prevents damaging back-current during power sequencing or standby |
| Operating temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive ECUs |
| ESD rating | HBM > 2000 V, CDM > 1000 V - ensures robustness in automated assembly and field environments |
| Output drive | ±24 mA at VCC = 3.0 V - drives standard TTL loads and 15 pF PCB traces without external buffers |
Pinout & Package
TSSOP20 (SOT360-1) package: 20-pin plastic thin shrink small outline, 4.4 mm body width, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output enable (active LOW) | Asserting LOW enables Q0–Q7; HIGH forces all outputs to high-impedance - independent of register state |
| 2–9 (D0–D7) | Data inputs | Asynchronous inputs sampled on rising CP edge; Schmitt-triggered for slow/noisy signal tolerance |
| 10 (GND) | Ground reference | 0 V return path for all internal logic and I/O; must be low-impedance for noise immunity |
| 11 (CP) | Positive-edge clock | LOW-to-HIGH transition latches Dn values; minimum pulse width 3.3 ns at 3.3 V |
| 12–19 (Q0–Q7) | Registered outputs | True-level outputs reflecting latched Dn states; 3-state capable with OE control |
| 20 (VCC) | Supply voltage | Primary power rail (1.2–3.6 V); powers both core logic and I/O buffers |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across −40 °C to +125 °C ambient, including thermal cycling and humidity testing |
| IOFF partial power-down | Automatically disables outputs and blocks reverse current when VCC = 0 V - critical for hot-plug and multi-rail systems |
| 5 V tolerant I/O | Accepts 0–5.5 V input signals and drives 5 V loads while powered from 1.2–3.6 V - eliminates external level translators |
| Schmitt-trigger inputs | Hysteresis ≥ 0.3 V at 3.3 V - rejects noise on slow-rising control lines (e.g., reset, enable) without external RC filtering |
| Flow-through pinout | Dn and Qn aligned on opposite sides (e.g., D0 pin 2 ↔ Q0 pin 19) - simplifies PCB routing and reduces trace crosstalk |
Applications
| Automotive Body Control Module | Industrial PLC I/O Expansion |
|---|---|
Use Scenario: Latching sensor status (door open/closed, seatbelt fastened) and driving LED indicators or relay drivers in vehicle body controllers. IC Role / Device Role / Timing Role: Octal register capturing parallel sensor inputs on each CAN/LIN message sync pulse; 3-state outputs isolate failed modules.

IC Role / Device Role / Timing Role: Synchronous latch synchronizing asynchronous fieldbus data to local clock domain; OE controlled by FPGA for dynamic bus arbitration. Use Value: 5 V tolerant inputs accept direct connection to 5 V TTL sensors/actuators without level-shifting components, reducing BOM count. |
| Automotive ADAS Camera Interface | Medical Imaging Data Capture |
Use Scenario: Capturing parallel pixel data streams from image sensors before serialization over MIPI CSI-2. IC Role / Device Role / Timing Role: Edge-triggered register holding one pixel clock cycle of raw sensor output; CP synchronized to sensor pixel clock. Use Value: Propagation delay ≤ 7.0 ns at 3.3 V ensures setup/hold timing margins for >100 MHz pixel clocks in high-resolution capture. | Use Scenario: Temporarily storing digitized analog front-end samples (e.g., ECG, EEG) before DMA transfer to processor memory. IC Role / Device Role / Timing Role: High-reliability latch buffering ADC output words; OE used to gate data flow during processor interrupt servicing. Use Value: AEC-Q100 qualification provides proven reliability for safety-critical medical electronics requiring long-term operational stability. |
Equivalent & Alternatives

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC574APWR | Commercial grade (−40 °C to +85 °C), no AEC-Q100 qualification; identical electrical specs and pinout | Not suitable for automotive under-hood or safety-critical functions | Select when cost-sensitive non-automotive designs require same functionality without qualification overhead |
| 74LVC574ABQ-Q100 | DHVQFN20 package (2.5 × 4.5 mm), same AEC-Q100 Grade 1 rating and electrical performance | Higher thermal efficiency and smaller footprint; requires rework-capable assembly process | Select for space-constrained automotive modules where thermal dissipation and board area are prioritized over TSSOP hand-solderability |
Compared with SN74LVC574APWR, the 74LVC574APW-Q100 adds automotive qualification and extended temperature range without sacrificing speed or drive strength; compared with 74LVC574ABQ-Q100, it trades compactness for easier inspection and rework in TSSOP20 packaging.

FAQ
What is the maximum clock frequency supported by the 74LVC574APW-Q100?
The device supports up to 150 MHz at VCC = 3.3 V and −40 °C to +85 °C, and 120 MHz across its full AEC-Q100 Grade 1 range (−40 °C to +125 °C). This is determined by propagation delay (tpd ≤ 7.0 ns) and minimum clock pulse width (tW ≥ 3.3 ns), verified per JEDEC JESD8-C and JESD36 standards.
Can the 74LVC574APW-Q100 safely interface with 5 V microcontrollers while powered from 3.3 V?
Yes - its inputs tolerate up to 5.5 V regardless of VCC level (1.2–3.6 V), and outputs drive 5 V TTL loads when VCC ≥ 2.7 V. No external level shifters are required, making it ideal for bridging 3.3 V FPGAs or MCUs to legacy 5 V peripheral buses in automotive gateways.
How does the IOFF feature protect the device during power sequencing?
When VCC drops to 0 V, the IOFF circuitry disables all outputs and blocks current flow between powered I/O pins and the unpowered VCC rail. This prevents destructive back-current from 5 V peripherals into the 3.3 V domain - a critical safeguard in multi-supply automotive ECUs undergoing controlled power-down sequences.
Is the TSSOP20 package of the 74LVC574APW-Q100 compatible with standard reflow profiles?
Yes - the SOT360-1 package is rated for standard lead-free reflow (J-STD-020), with peak temperature up to 260 °C for 30 seconds. Its 0.65 mm pitch and exposed pad design ensure reliable solder joint formation and thermal performance in automotive-grade manufacturing environments.
