Product details
Overview
74HC174PW-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified hex positive-edge-triggered D-type flip-flop with asynchronous master reset, operating from 2.0 V to 6.0 V supply, delivering 50 ns typical propagation delay at 4.5 V and supporting automotive ambient temperatures up to +125 °C. It integrates six independent D-flip-flops sharing a common clock (CP) and master reset (MR), used for synchronous data latching and state retention in engine control units and ADAS sensor interfaces.
For engineers reviewing the 74HC174PW-Q100 datasheet, 74HC174PW-Q100 pinout, 74HC174PW-Q100 application, or 74HC174PW-Q100 equivalent, key selection considerations include CMOS-level input compatibility, TSSOP16 thermal performance at +125 °C, set-up/hold timing margins under 15 ns, and AEC-Q100 qualification evidence for automotive powertrain modules.
Technical Context
This device implements six edge-triggered storage elements with fully asynchronous reset-each D-input is sampled on the LOW-to-HIGH transition of CP, and MR forces all Q-outputs LOW independently of clock phase. The logic architecture supports deterministic state capture without metastability propagation across flip-flops when setup/hold times are met.
Input clamping diodes enable safe interfacing to voltages exceeding VCC when current-limiting resistors are used; output drive capability is ±25 mA per pin with VOH ≥ 3.98 V and VOL ≤ 0.26 V at VCC = 4.5 V and IO = ±4.0 mA, ensuring robust noise immunity in noisy automotive harness environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct interface with 3.3 V and 5 V microcontroller I/O domains without level translation |
| Propagation Delay (tpd) | 20 ns typ @ VCC = 4.5 V - supports reliable operation up to 24 MHz system clock frequency in timing-critical control loops |
| Set-up Time (tsu) | 12 ns min @ VCC = 4.5 V - defines minimum data stability window before clock edge for guaranteed capture |
| Hold Time (th) | 3 ns min @ VCC = 4.5 V - specifies shortest time data must remain stable after clock edge to avoid invalid state |
| Output Drive Strength | ±4.0 mA @ VOH/VOL - sufficient to directly drive LED indicators or small-signal logic loads in dashboard modules |
| Ambient Temperature Range | −40 °C to +125 °C - validated for under-hood placement in engine management systems |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive board-level ESD robustness requirements per ISO 10605 |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1), 16-pin, body width 4.4 mm, optimized for high-density automotive PCB layouts with improved thermal dissipation over SO16.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (MR) | Asynchronous master reset input | Active-LOW signal that forces all six Q-outputs LOW regardless of clock state - critical for fail-safe initialization |
| 2, 5, 7, 10, 12, 15 (Q0–Q5) | Flip-flop outputs | Complementary registered data outputs; each reflects stored Dn value sampled on prior CP rising edge |
| 3, 4, 6, 11, 13, 14 (D0–D5) | Data inputs | Independent parallel data lanes synchronized to CP; require valid levels ≥12 ns before and ≥3 ns after clock edge |
| 8 (GND) | Ground reference | 0 V return path for all internal logic and I/O; requires low-inductance connection to minimize ground bounce |
| 9 (CP) | Clock input | Edge-sensitive control line - only LOW-to-HIGH transitions trigger data capture; immune to HIGH-to-LOW glitches |
| 16 (VCC) | Positive supply voltage | Primary power rail; decoupling capacitor (100 nF ceramic) required within 5 mm for stable switching performance |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including temperature cycling, HTOL, and ESD stress tests |
| CMOS-level input compatibility | VIH ≥ 3.15 V and VIL ≤ 1.35 V @ VCC = 4.5 V - ensures interoperability with 3.3 V MCU GPIOs without external translators |
| Input clamp diodes | Enables safe interface to signals up to VCC + 0.5 V using series current-limiting resistors - eliminates need for external TVS in many sensor front-ends |
| Low dynamic power consumption | CPD = 17 pF - limits switching power to <1 μW/MHz at 3.3 V, reducing thermal load in sealed ECUs |
| High noise immunity | Typical noise margin >1.0 V at VCC = 4.5 V - suppresses false triggering from ignition noise or alternator ripple |
Applications
| Engine Control Unit (ECU) Input Capture | ADAS Camera Sensor Interface |
|---|---|
Use Scenario: Capturing crankshaft position sensor pulses synchronized to main ECU clock for precise ignition timing calculation. IC Role / Device Role / Timing Role: Hex D-flip-flop latches six independent sensor channels on rising edge of 10 MHz system clock, with MR used during cold-start reset.

IC Role / Device Role / Timing Role: Stores decoded warning flags (e.g., brake failure, low oil) and presents them synchronously to display controller via parallel bus. Use Value: Guarantees glitch-free visual feedback by eliminating race conditions between CAN RX interrupt and display update cycles. | Use Scenario: Latching torque sensor ADC outputs before feeding into EPS motor control loop for real-time torque assist calculation. IC Role / Device Role / Timing Role: Acts as a synchronized sample-and-hold stage aligned to PWM carrier frequency to reduce jitter-induced torque ripple.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC174QPWRQ1 | TI part with identical pinout and AEC-Q100 Grade 1 rating; tpd = 21 ns @ 4.5 V vs. 20 ns for Nexperia | Same functional role but slightly higher propagation delay; compatible in existing PCB layouts | Select when TI supply chain preference applies or when needing TI-specific qualification documentation |
| 74HCT174PW-Q100 | TTL-compatible inputs (VIH = 2.0 V min); otherwise identical package, timing, and qualification | Required when interfacing legacy 5 V TTL logic without level shifters; not suitable for pure CMOS 3.3 V systems | Choose only if driving from 5 V sources with marginal noise margins - otherwise prefer HC version for lower power |
Compared with SN74HC174QPWRQ1, the 74HC174PW-Q100 offers marginally faster propagation and lower ICC; versus 74HCT174PW-Q100, it provides superior noise immunity and reduced static power but requires CMOS-level input drivers.

FAQ
Is 74HC174PW-Q100 pin-compatible with standard 74HC174 devices?
Yes - the TSSOP16 (SOT403-1) footprint matches JEDEC MO-153 standards and is mechanically and electrically identical to non-automotive 74HC174PW variants. All 16 pins retain identical functions, voltage tolerances, and timing behavior, enabling drop-in replacement in qualified designs.
What is the maximum clock frequency supported at 3.3 V supply?
At VCC = 3.3 V, the device supports fmax ≈ 18 MHz (derived from tpd = 33 ns max and tW = 20 ns min per datasheet Table 7). This is confirmed by dynamic characterization at 25 °C and −40 °C to +85 °C ranges, with derating applied above 85 °C ambient.
Does the master reset (MR) affect propagation delay measurements?
Yes - MR assertion overrides clock activity and forces immediate Q-output transition to LOW within tPHL = 16 ns (typ) at VCC = 4.5 V. Propagation delay from MR to Q is separately characterized and does not depend on CP timing, enabling predictable fail-safe response in safety-critical subsystems.
Can 74HC174PW-Q100 drive LEDs directly without current-limiting resistors?
No - although output drive strength reaches ±25 mA, sustained LED current must be limited to ≤4 mA per pin to stay within recommended operating conditions and prevent cumulative thermal stress. External 1 kΩ resistors are required for typical 2 mA LED biasing at 5 V VCC.
