Product details
Overview
74HC574PW-Q100 from Nexperia is an automotive-grade, 8-bit positive-edge-triggered D-type flip-flop with 3-state outputs in TSSOP20 package. It operates across 2.0 V to 6.0 V supply, supports -40 °C to +125 °C ambient range, and features independent clock (CP) and active-low output enable (OE) for bus-oriented data latching in automotive control modules.
For engineers reviewing the 74HC574PW-Q100 datasheet, 74HC574PW-Q100 pinout, 74HC574PW-Q100 application, or 74HC574PW-Q100 equivalent, this device serves as a high-noise-immunity, AEC-Q100 Grade 1–qualified register for CAN/LIN subsystems, body control units, and ADAS sensor interface buffering where precise edge-triggered data capture and bus contention avoidance are required.
Technical Context
This device implements eight independent D-type flip-flops sharing a common clock input (CP) and a single active-low 3-state output enable (OE). Each flip-flop captures the logic state of its D-input on the LOW-to-HIGH transition of CP, meeting setup/hold time requirements down to 2 ns at VCC = 6.0 V.
OE controls output impedance independently of internal register state: when HIGH, all Q0–Q7 outputs enter high-impedance OFF-state without altering stored data; inputs include clamp diodes enabling safe interfacing to voltages exceeding VCC via current-limiting resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HC CMOS - TTL-compatible input thresholds not required; operates from 2.0 V to 6.0 V with rail-to-rail output swing. |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood automotive use without derating. |
| Propagation Delay (tpd) | 14 ns (typ) at VCC = 6.0 V, CL = 50 pF - Enables reliable operation up to 35 MHz clock frequency in synchronous data paths. |
| Output Drive Strength | ±7.8 mA at VCC = 6.0 V - Sufficient to drive standard 50 pF loads and multiple CMOS inputs without external buffers. |
| 3-State Enable Time (ten) | 13 ns (typ) at VCC = 6.0 V - Ensures fast bus release for time-critical multiplexed communication interfaces. |
| Supply Current (ICC) | 8.0 μA (typ) at VCC = 6.0 V, static - Supports ultra-low-power sleep modes in always-on vehicle networks. |
| Input Clamp Diodes | Integrated - Allows direct connection to 12 V or 24 V auxiliary rails using series current-limiting resistors, eliminating level-shifters. |
Pinout & Package
TSSOP20 package (SOT360-1), 4.4 mm body width, 0.65 mm pitch, 20-terminal surface-mount plastic thin shrink small outline package with exposed pad option for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low 3-state output enable | Drives all Q0–Q7 into high-Z when HIGH; no effect on internal flip-flop states. |
| 2–9 (D0–D7) | Data inputs | Asynchronous inputs sampled on rising edge of CP; include clamp diodes for overvoltage tolerance. |
| 10 (GND) | Ground reference | 0 V return path for all internal circuitry and output drivers; must be low-impedance for noise immunity. |
| 11 (CP) | Clock input | LOW-to-HIGH edge triggers simultaneous latching of all Dn inputs into respective flip-flops. |
| 12–19 (Q7–Q0) | 3-state non-inverting outputs | Reflect stored Dn values when OE = LOW; enter high-Z when OE = HIGH for bus sharing. |
| 20 (VCC) | Positive supply | 2.0 V to 6.0 V operating range; decoupling capacitor required within 5 mm of pin for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C with full reliability testing (HTOL, TC, UHAST, etc.). |
| Wide supply voltage range | 2.0 V to 6.0 V operation enables direct integration with 3.3 V microcontrollers and 5 V legacy systems. |
| CMOS low power dissipation | Typical ICC = 8 μA at 6 V static; dynamic power scales predictably via CPD = 22 pF for accurate thermal modeling. |
| High noise immunity | Input hysteresis and >40 % VCC noise margin ensure robust operation in electrically noisy engine compartments. |
| Side-wettable flanks (TSSOP) | SOT360-1 package supports automated optical inspection (AOI) of solder joints for zero-defect automotive manufacturing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT574PW-Q100 | TTL-compatible inputs (VIH = 2.0 V min); identical pinout, timing, and packaging. | Better suited for mixed 5 V TTL/CMOS systems; requires VIH ≥ 2.0 V, unlike HC's CMOS-level VIH = 0.7×VCC. | Select when interfacing legacy 5 V microcontrollers or FPGAs with standard TTL thresholds. |
| SN74LVC574APWRE4 | 3.3 V only (1.65–3.6 V); lower propagation delay (5.4 ns typ); different pinout (OE on pin 19, CP on pin 1). | Not AEC-Q100 qualified; rated for industrial (-40 °C to +125 °C) but lacks automotive stress testing. | Choose only for non-automotive 3.3 V designs requiring higher speed and lower power; not drop-in compatible. |
Compared with 74HC574PW-Q100, the 74HCT574PW-Q100 offers seamless integration into 5 V TTL environments without level shifters, while SN74LVC574APWRE4 trades automotive qualification and voltage flexibility for raw speed and lower static current in 3.3 V systems.

FAQ
What is the maximum clock frequency supported by the 74HC574PW-Q100?
The 74HC574PW-Q100 supports a maximum clock frequency of 35 MHz at VCC = 6.0 V and CL = 50 pF, verified per Table 7 of the datasheet. At 4.5 V, fmax drops to 30 MHz, and at 2.0 V it is 6.0 MHz. These values assume proper PCB layout, decoupling, and load conditions - actual system-level timing must account for board trace delays and fanout.
Can the 74HC574PW-Q100 operate reliably at 3.3 V supply?
Yes - the 74HC574PW-Q100 is fully specified from 2.0 V to 6.0 V, including 3.3 V operation. At VCC = 3.3 V, typical propagation delay is ~22 ns and VIH is 2.31 V (0.7 × 3.3 V), ensuring compatibility with 3.3 V microcontrollers. All AC/DC parameters in Tables 5–9 include 3.3 V data points.
How does the OE pin behave during power-up or brownout conditions?
The OE pin is buffered and internally pulled down via weak NMOS (not a hard pull-down), so it defaults to LOW during power ramp-up, enabling outputs. However, if OE is driven externally, its state depends on external circuitry. For fail-safe operation, tie OE to GND through a 10 kΩ resistor to guarantee enabled outputs until firmware asserts control.
Is the TSSOP20 package (SOT360-1) lead-free and RoHS compliant?
Yes - the 74HC574PW-Q100 uses a lead-free, halogen-free, RoHS-compliant TSSOP20 package (SOT360-1) with matte tin finish. It meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and supports standard Pb-free reflow profiles (peak 260 °C, 10 s max above 220 °C).
