Product details
Overview
74HC574D-Q100 from Nexperia is an automotive-grade 8-bit positive-edge-triggered D-type flip-flop with 3-state outputs, designed for bus-oriented data latching in automotive control modules. It operates across 2.0 V to 6.0 V supply, supports -40 °C to +125 °C ambient, and features independent clock (CP) and active-low output enable (OE) inputs enabling precise timing control and bus isolation.
For engineers reviewing the 74HC574D-Q100 datasheet, 74HC574D-Q100 pinout, 74HC574D-Q100 application, or 74HC574D-Q100 equivalent, key selection criteria include edge-triggered register behavior, 3-state bus drive capability, AEC-Q100 Grade 1 qualification, and SO20 package compatibility with legacy PCB layouts.
Technical Context
This device implements eight independent D-type flip-flops synchronized to the LOW-to-HIGH transition of CP, with set-up time as low as 10 ns (VCC = 6.0 V) and hold time of 5 ns. All flip-flops share a common OE input that places outputs in high-impedance state without affecting internal latch states.
Input clamping diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The SO20 package (SOT163-1) provides mechanical robustness and thermal performance validated for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 8-bit positive-edge-triggered D-type register with 3-state outputs |
| Supply Voltage Range | 2.0 V to 6.0 V - supports wide-input automotive power rails including 3.3 V and 5 V systems |
| Operating Temperature | -40 °C to +125 °C - qualified for engine control unit (ECU) and body control module (BCM) placement |
| Propagation Delay (tpd) | 14 ns typical at VCC = 6.0 V - enables reliable operation up to 35 MHz clock frequency |
| Output Drive Strength | ±7.8 mA at VCC = 4.5 V - sufficient for driving standard CMOS/TTL loads on shared data buses |
| AEC-Q100 Grade | Grade 1 - certified for automotive applications requiring operation up to +125 °C ambient |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - ensures robustness during board assembly and in-vehicle handling |
Pinout & Package
74HC574D-Q100 uses the SO20 plastic small outline package (SOT163-1), 20-pin, 7.5 mm body width, with gull-wing leads suitable for reflow soldering and automated optical inspection.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE | Active-low 3-state output enable - disables all Q outputs without altering stored data |
| 2–9 | D0–D7 | Asynchronous data inputs - sampled on rising CP edge and latched into respective flip-flops |
| 10 | GND | Ground reference - required for stable logic thresholds and noise immunity |
| 11 | CP | Clock input - triggers simultaneous capture of all D inputs on LOW-to-HIGH transition |
| 12–19 | Q0–Q7 | 3-state non-inverting outputs - reflect latched D values when OE = LOW; high-Z when OE = HIGH |
| 20 | VCC | Positive supply - powers internal logic and output drivers; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 - validated for continuous operation at +125 °C ambient in safety-critical ECUs |
| Bus interface capability | 3-state non-inverting outputs with common OE - enables multi-master data bus sharing without contention |
| Input voltage tolerance | Clamp diodes on all inputs - permits safe connection to signals exceeding VCC using series resistors |
| Low-power CMOS design | ICC ≤ 8 μA typical at VCC = 6.0 V - minimizes quiescent current in always-on vehicle subsystems |
| Wide voltage compatibility | 2.0 V to 6.0 V operation - interoperable with 3.3 V microcontrollers and 5 V legacy peripherals |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
Use Scenario: Latching sensor data (e.g., throttle position, coolant temperature) before ADC sampling in real-time engine management loops. IC Role / Device Role / Timing Role: Synchronous 8-bit data register capturing parallel analog-to-digital converter outputs on rising clock edge. Use Value: Ensures deterministic timing alignment between sensor acquisition and CPU read cycles, eliminating metastability in high-speed ECU timing paths. |
Use Scenario: Isolating door lock actuator command lines from shared CAN/LIN gateway microcontroller I/O ports. IC Role / Device Role / Timing Role: Bus-oriented 3-state latch buffering microcontroller GPIOs to prevent back-driving during sleep mode transitions. Use Value: Enables clean power sequencing by disabling output drivers via OE while preserving latch state - critical for low-leakage BCM standby operation. |
| Instrument Cluster Display Driver | ADAS Camera Interface Buffer |
Use Scenario: Holding pixel data from graphics controller before serial shift-out to LED driver ICs in digital instrument clusters. IC Role / Device Role / Timing Role: Parallel-to-serial staging register synchronizing burst-mode display data transfers with master clock domain.

Use Scenario: Buffering raw image data from MIPI CSI-2 deserializer before routing to SoC image processor in surround-view systems. IC Role / Device Role / Timing Role: High-speed 8-bit latch capturing parallel video bus segments during clock domain crossing between serializer and processor domains. Use Value: Provides deterministic sampling point for asynchronous camera streams, reducing frame sync jitter in multi-camera fusion pipelines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT574D-Q100 | TTL-compatible input thresholds (VIH = 2.0 V min); identical pinout and timing | Better interoperability with 5 V TTL logic families; slightly higher ICC at VCC = 5.5 V | Select when interfacing legacy 5 V microcontrollers or discrete logic without level shifters |
| SN74LVC574AQDRQ1 | Lower VCC range (1.65 V to 3.6 V); 32 mA output drive; different pin assignment | Optimized for 3.3 V automotive infotainment SoCs; not pin-compatible with SO20 layout | Choose only if redesigning PCB for lower-voltage domains and higher drive strength is required |
Compared with 74HCT574D-Q100, the original part offers broader supply flexibility (2.0–6.0 V vs. 4.5–5.5 V), while SN74LVC574AQDRQ1 trades voltage range for enhanced speed and drive but requires layout revision due to non-matching pinout.

FAQ
What is the maximum clock frequency supported by the 74HC574D-Q100?
The 74HC574D-Q100 supports a maximum clock frequency of 35 MHz at VCC = 6.0 V and CL = 50 pF, verified per dynamic characteristics in the datasheet. At 4.5 V supply, fmax drops to 30 MHz. These values assume proper PCB layout with minimized trace inductance and adequate VCC decoupling near pin 20.
Can OE be toggled while CP is active without corrupting stored data?
Yes - the OE input is asynchronous and does not affect internal flip-flop states. Outputs enter high-impedance mode immediately upon OE going HIGH, regardless of CP activity or timing. Data remains latched until the next valid CP rising edge, satisfying AEC-Q100 functional safety requirements for predictable bus arbitration.
Is the SO20 package (SOT163-1) RoHS and REACH compliant?
Yes - the 74HC574D-Q100 in SO20 packaging meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound. Full compliance documentation is available through Nexperia's product change notifications and material declarations portal.
How does the 74HC574D-Q100 differ from the commercial-grade 74HC574D?
The -Q100 suffix denotes full AEC-Q100 Grade 1 qualification, including extended temperature validation (-40 °C to +125 °C), enhanced ESD robustness (HBM > 2000 V), and lot-level automotive traceability. Electrically, it matches the commercial version but undergoes additional stress testing and screening per automotive quality standards.
