Product details
Overview
74HC273D-Q100 from Nexperia is an automotive-grade octal positive-edge-triggered D-type flip-flop with synchronous data capture and asynchronous master reset (MR). It operates across 2.0 V to 6.0 V supply, delivers ≤30 ns propagation delay at 4.5 V, supports -40 °C to +125 °C ambient, and features CMOS-level inputs for low-power digital control in engine control units and ADAS domain controllers.
For engineers reviewing the 74HC273D-Q100 datasheet, 74HC273D-Q100 pinout, 74HC273D-Q100 application, or 74HC273D-Q100 equivalent, this device is selected for high-reliability edge-triggered state storage where deterministic timing, AEC-Q100 Grade 1 qualification, and robust noise immunity are required in automotive signal conditioning and interface logic stages.
Technical Context
The 74HC273D-Q100 implements eight independent D-type flip-flops sharing a common clock (CP) and active-low master reset (MR), each capturing Dn input on the LOW-to-HIGH CP transition when setup/hold times are met. MR forces all Qn outputs LOW regardless of CP or Dn states, enabling hard system reset without clock dependency.
Its CMOS architecture ensures rail-to-rail output swing, input clamp diodes allow overvoltage-tolerant interfacing via current-limiting resistors, and dynamic power dissipation is governed by CPD = 20 pF - enabling precise calculation of switching power under varying clock and load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports wide-battery automotive systems including 3.3 V and 5 V domains |
| Propagation Delay (tpd) | 15 ns (typ) at VCC = 4.5 V, CL = 50 pF - enables reliable operation up to 24 MHz maximum clock frequency |
| Set-up Time (tsu) | 12 ns (min) at VCC = 4.5 V - defines minimum Dn stability window before CP rising edge for valid latching |
| Hold Time (th) | 3 ns (min) at VCC = 4.5 V - specifies minimum Dn stability duration after CP rising edge |
| Output Drive Strength | ±4.0 mA (VOH/VOL) at VCC = 4.5 V - sufficient to drive standard CMOS loads or fan-out to ≥10 74HC inputs |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive environments |
| Power Dissipation Capacitance | CPD = 20 pF - used to compute dynamic power: PD = CPD × VCC² × fi + Σ(CL × VCC² × fo) |
Pinout & Package
74HC273D-Q100 uses the SO20 (SOT163-1) package: plastic small outline, 20 leads, 7.5 mm body width, 1.27 mm pitch, and gull-wing leads compatible with standard reflow and AOI inspection.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | MR | Active-low master reset - asynchronously clears all Qn outputs to LOW, overriding clock and data |
| 2–9, 12–19 | Q0–Q7 / D0–D7 | Eight bidirectional data paths: even pins (2,5,6,9,12,15,16,19) = outputs; odd pins (3,4,7,8,13,14,17,18) = inputs |
| 10 | GND | Ground reference for all internal circuitry and I/O - must be connected to system 0 V plane |
| 11 | CP | Clock input - triggers simultaneous sampling of all Dn inputs on LOW-to-HIGH transition |
| 20 | VCC | Positive supply rail - powers internal logic and output drivers; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C with full reliability testing per stress and lifetime requirements |
| Input clamp diodes | Enable safe interfacing to voltages exceeding VCC using external current-limiting resistors - eliminates need for level shifters |
| High noise immunity | VIH/VIL thresholds defined as percentage of VCC (e.g., VIH = 3.15 V at VCC = 4.5 V), ensuring robust operation in electrically noisy vehicle harnesses |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events |
| ESD protection | HBM >2000 V and CDM >1000 V - protects against handling and assembly ESD without external suppressors |
Applications

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 |
|---|---|---|---|
| 74HCT273D-Q100 | TTL-compatible inputs (VIH = 2.0 V min at VCC = 4.5 V); otherwise identical timing, packaging, and qualification | Preferred when interfacing legacy 5 V TTL logic or microcontrollers with non-CMOS output drivers | Select if driving from 5 V TTL sources; retains same pinout, thermal profile, and automotive qualification |
| SN74LV273AQPWRQ1 | TI part with LV logic family: lower VCC range (1.65 V–5.5 V), higher fmax (80 MHz at 3.3 V), but only AEC-Q100 Grade 2 (-40 °C to +105 °C) | Suitable for 3.3 V-only domains requiring higher speed, but not for under-hood +125 °C operation | Choose only for 3.3 V systems needing >24 MHz clock rates; verify thermal derating for target ambient |
Compared with 74HCT273D-Q100, the TTL-input variant maintains identical automotive qualification and timing but eases integration with older 5 V logic; versus SN74LV273AQPWRQ1, the 74HC273D-Q100 trades speed for extended temperature capability and broader supply flexibility.

FAQ
What is the maximum clock frequency supported by the 74HC273D-Q100?
The 74HC273D-Q100 achieves a maximum clock frequency (fmax) of 24 MHz at VCC = 4.5 V and CL = 50 pF, verified across -40 °C to +125 °C. At VCC = 6.0 V, fmax reaches 28 MHz under the same load, limited by propagation delay (tpd ≤ 26 ns) and set-up/hold timing margins.
Can the 74HC273D-Q100 interface directly with 5 V TTL outputs?
No - the 74HC273D-Q100 has CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V), which do not reliably recognize standard 5 V TTL HIGH levels (2.4 V min). For TTL compatibility, use the pin-identical 74HCT273D-Q100, whose VIH threshold is 2.0 V at VCC = 4.5 V to 5.5 V.
How does the master reset (MR) behave during power-up sequences?
The MR input is active-low and asynchronous: asserting MR LOW at any time - including during VCC ramp-up - forces all Qn outputs LOW immediately, regardless of CP state or Dn values. To ensure known initial state, tie MR to a power-on reset circuit that holds it LOW until VCC stabilizes above 2.0 V.
Is the SO20 package (SOT163-1) lead-free and RoHS-compliant?
Yes - the 74HC273D-Q100 in SO20 packaging is manufactured with 100 % matte tin lead finish, fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, and qualified for lead-free reflow soldering per JEDEC J-STD-020.
