Product details
Overview
74HCT74PW-Q100 from Nexperia is an automotive-qualified dual positive-edge-triggered D-type flip-flop with independent asynchronous set (nSD) and reset (nRD) inputs, complementary Q/nQ outputs, TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V), propagation delay of 18 ns typical at 4.5 V, and operation from −40 °C to +125 °C in TSSOP14 package - used for synchronous data latching and state storage in engine control units and ADAS sensor interfaces.
For engineers reviewing the 74HCT74PW-Q100 datasheet, 74HCT74PW-Q100 pinout, 74HCT74PW-Q100 application, or 74HCT74PW-Q100 equivalent, key selection criteria include edge-triggered timing integrity under automotive temperature extremes, Schmitt-trigger clock tolerance for noisy environments, TTL-level input compatibility with legacy microcontrollers, and AEC-Q100 Grade 1 qualification for under-hood deployment.
Technical Context
This device implements two independent D-type flip-flops sharing no internal logic coupling; each features separate nD, nCP, nSD, and nRD terminals with fully asynchronous active-low set/reset overriding clocked behavior. The Schmitt-trigger action on all clock inputs ensures robust triggering despite slow or noisy rise/fall times up to 83 ns/V at VCC = 6.0 V.
Input clamping diodes enable safe interfacing to voltages exceeding VCC when current-limiting resistors are used; output drive capability is symmetrical (±4 mA at VCC = 4.5 V), with balanced tPLH/tPHL delays (18 ns typ) and low dynamic power dissipation (CPD = 29 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HCT - TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at 5 V) ensure interoperability with legacy 5 V microcontrollers and FPGAs. |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive applications including powertrain and chassis control modules. |
| Propagation Delay | 18 ns typical (nCP → nQ, VCC = 4.5 V, CL = 50 pF) - enables reliable 22 MHz maximum clock frequency in real-time control loops. |
| Supply Voltage Range | 4.5 V to 5.5 V - tightly regulated window ensures stable timing margins and noise immunity in automotive 5 V rail systems. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets stringent automotive ESD requirements for assembly and field operation reliability. |
| Output Drive | ±4 mA at VCC = 4.5 V - sufficient to directly drive multiple 74-series inputs or small LED indicators without external buffers. |
| Power Dissipation | CPD = 29 pF - enables accurate dynamic power calculation (PD = CPD × VCC² × fi × N) for thermal budgeting in dense PCB layouts. |
Pinout & Package
TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14 leads, body width 4.4 mm, 0.65 mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1RD | Asynchronous reset (active LOW) | Forces 1Q = LOW regardless of clock or data; critical for system initialization and fault recovery in safety-critical ECUs. |
| 1D | Data input | Samples value on rising edge of 1CP; requires setup time ≥15 ns and hold time ≥3 ns at VCC = 4.5 V. |
| 1CP | Clock input (LOW-to-HIGH edge-triggered) | Schmitt-triggered - accepts slow edges down to 83 ns/V, eliminating need for external signal conditioning in noisy environments. |
| 1SD | Asynchronous set (active LOW) | Forces 1Q = HIGH independently of clock; used for presetting known states during boot or diagnostic modes. |
| 1Q / 1Q | True and complement outputs | Simultaneous Q/nQ delivery enables direct connection to differential receivers or redundant logic paths in ASIL-B designs. |
| GND / VCC | Power supply terminals | Pin 7 = GND, Pin 14 = VCC; decoupling capacitor placement adjacent to these pins minimizes switching noise coupling into analog subsystems. |
| 2RD / 2SD / 2CP / 2D / 2Q / 2Q | Second flip-flop equivalents | Electrically isolated from first section - supports dual-channel sampling (e.g., CAN TX/RX strobes or dual-sensor synchronization). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with lifetime reliability testing - required for engine control, transmission, and braking module integration. |
| Asynchronous set/reset per channel | Independent nSD/nRD inputs allow deterministic state forcing without clock dependency - essential for fail-safe shutdown sequences. |
| Schmitt-trigger clock inputs | Enables robust edge detection on signals with >100 mV noise margin and rise/fall times up to 200 ns - eliminates metastability in low-speed sensor interfaces. |
| TTL-compatible input thresholds | VIH = 2.0 V min, VIL = 0.8 V max at 5 V supply - guarantees interoperability with legacy 5 V MCU GPIOs and industrial PLC outputs. |
| Symmetrical output impedance | Matched tPLH/tPHL (18 ns typ) and VOH/VOL (3.84 V/0.15 V at 4 mA) reduce skew in timing-critical feedback paths like PWM dead-time generation. |
Applications
| Engine Control Unit (ECU) | Advanced Driver Assistance Systems (ADAS) |
|---|---|
Use Scenario: Capturing crankshaft position pulses synchronized to camshaft reference for precise ignition timing. IC Role / Device Role / Timing Role: Dual flip-flop latches rising edges of Hall-effect sensor outputs on separate channels, enabling 360°/720° crank angle resolution with sub-degree accuracy. Use Value: Asynchronous reset ensures deterministic zero-angle alignment after power-on reset; Schmitt-triggered clocks reject EMI from ignition coils. |
Use Scenario: Synchronizing radar echo sampling windows with chirp start signals in 77 GHz front-end modules. IC Role / Device Role / Timing Role: One section captures chirp trigger edge; second section gates ADC sample-enable pulse to align with RF burst duration. Use Value: Matched propagation delays (<20 ns) between channels minimize timing skew across parallel sensor chains; AEC-Q100 rating ensures reliability in vibration-prone mounting locations. |
| Body Control Module (BCM) | Electric Power Steering (EPS) |
Use Scenario: Debouncing door lock/unlock switch inputs subject to mechanical bounce and battery voltage transients. IC Role / Device Role / Timing Role: Each flip-flop filters a separate switch line using clocked sampling at 10 kHz, with asynchronous reset clearing metastable states. Use Value: TTL-level inputs interface directly to 5 V switch matrices; low ICC (<80 μA) extends battery standby life in always-on BCM configurations. |
Use Scenario: Latching torque sensor fault flags before motor shutdown to preserve diagnostic history across ignition cycles. IC Role / Device Role / Timing Role: Flip-flop stores fault status on rising edge of safety monitor pulse; complement output drives LED indicator and CAN error frame generator. Use Value: Independent set/reset allows non-volatile flag retention during brief VCC dips; 125 °C rating supports placement near EPS motor heat sinks. |
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 |
|---|---|---|---|
| SN74HCT74QPWRQ1 | TI part with identical pinout, same AEC-Q100 Grade 1, but higher ICC (100 μA max vs. 80 μA) and no DHVQFN option. | Validated in TI's automotive reference designs for infotainment audio routing; less common in powertrain due to higher quiescent current. | Select when requiring TI's broad support ecosystem or existing design reuse with TI evaluation boards. |
| MC74HC74ADTR2G | ON Semiconductor part with CMOS inputs (VIH = 3.15 V min), wider VCC range (2–6 V), but only AEC-Q100 Grade 2 (−40 °C to +105 °C). | Used in HVAC control modules where extended temperature is unnecessary; unsuitable for under-hood engine bay placement. | Choose for cost-sensitive cabin applications needing wider supply flexibility but not full Grade 1 thermal range. |
Compared with SN74HCT74QPWRQ1, 74HCT74PW-Q100 offers lower static current for battery-sensitive modules; versus MC74HC74ADTR2G, it delivers guaranteed operation at 125 °C - making it the only choice for engine compartment timing-critical latching.

FAQ
What is the maximum clock frequency supported by the 74HCT74PW-Q100?
The 74HCT74PW-Q100 supports a maximum clock frequency of 22 MHz at VCC = 4.5 V and CL = 50 pF, based on its 18 ns typical propagation delay (tPLH/tPHL). At VCC = 5.0 V with reduced load (CL = 15 pF), fmax reaches 59 MHz - verified across −40 °C to +125 °C per AEC-Q100 test conditions.
Can the 74HCT74PW-Q100 operate with a 3.3 V supply?
No - the 74HCT74PW-Q100 is specified only for 4.5 V to 5.5 V operation per its Recommended Operating Conditions table. At 3.3 V, VIH threshold (2.0 V min) becomes unattainable with standard 3.3 V logic families, risking unreliable clock and data recognition; use 74HC74PW-Q100 instead for 2–6 V flexibility.
How does the Schmitt-trigger clock input improve noise immunity?
The Schmitt-trigger on nCP provides hysteresis (~0.4 V at VCC = 5 V), rejecting noise spikes <400 mV and tolerating slow rise/fall times up to 200 ns. This eliminates false triggering from EMI in engine bays and allows direct connection to unconditioned sensor outputs without RC filtering.
Is the exposed pad on the TSSOP14 package electrically connected?
No - the exposed pad in SOT402-1 (TSSOP14) is a thermal enhancement feature only, with no electrical connection. Per Nexperia's datasheet, it may be left floating or tied to GND for improved thermal performance, but must never be connected to VCC or other voltage rails.
