Product details
Overview
74HC273PW-Q100 from Nexperia is an automotive-grade octal positive-edge-triggered D-type flip-flop with synchronous data capture and asynchronous master reset (active LOW). 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 74HC273PW-Q100 datasheet, 74HC273PW-Q100 pinout, 74HC273PW-Q100 application, or 74HC273PW-Q100 equivalent, this device serves as a timing-critical register for parallel data latching, clock-domain synchronization, and fault-tolerant state storage in AEC-Q100 Grade 1 automotive systems requiring deterministic edge-triggered behavior and robust reset control.
Technical Context
This device implements eight independent D-type flip-flops sharing a common clock (CP) and a single active-LOW master reset (MR), enabling simultaneous state initialization or update on every rising CP edge. Its architecture enforces strict setup (≥12 ns at 4.5 V) and hold (≥3 ns) timing requirements to guarantee metastability-free sampling of Dn inputs.
Input clamping diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors, while output drive capability (±4 mA at 4.5 V) supports direct connection to TTL or CMOS loads without buffering. The TSSOP20 package (SOT360-1) provides side-wettable flanks for automated optical inspection in high-reliability PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HC series - CMOS-level input thresholds, rail-to-rail output swing, low static current (≤160 μA at 125 °C) |
| Supply Voltage Range | 2.0 V to 6.0 V - Enables direct interface with 3.3 V and 5 V logic domains without level shifters |
| Propagation Delay (CP→Qn) | 15 ns (typ) / 30 ns (max) at VCC = 4.5 V, CL = 50 pF - Supports ≥30 MHz clock operation in synchronous control paths |
| Set-up / Hold Time | 12 ns / 3 ns at VCC = 4.5 V - Defines minimum data stability window before and after CP rising edge for reliable capture |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood automotive applications |
| ESD Protection | HBM >2000 V, CDM >1000 V - Ensures robustness during board handling and in-vehicle ESD events |
| Power Dissipation Cap. | 20 pF - Used to calculate dynamic power: PD = CPD × VCC² × fi + Σ(CL × VCC² × fo) |
Pinout & Package
TSSOP20 package (SOT360-1): 20-pin plastic thin shrink small outline, 4.4 mm body width, 0.65 mm pitch, side-wettable flanks for AOI.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | MR | Master reset input - Active LOW; forces all Qn outputs LOW independently of clock or data |
| 2 | VCC | Positive supply - Must be decoupled locally; supports 2.0–6.0 V operation |
| 3–4, 7–8, 13–14, 17–18 | D0–D7 | Data inputs - Sampled on LOW-to-HIGH CP transition if setup/hold times met |
| 5, 6, 9, 12, 15, 16, 19, 2 | Q0–Q7 | Flip-flop outputs - Reflect Dn state captured at prior CP edge; high-impedance only during power-down |
| 10 | GND | Ground reference - Return path for all internal currents; must be low-impedance |
| 11 | CP | Clock input - Positive-edge triggered; rising edge initiates synchronous data transfer |
| 20 | VCC | Positive supply - Same net as Pin 2; dual VCC pins reduce supply inductance |
Key Features

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 |
|---|---|---|---|
| 74HCT273PW-Q100 | TTL-compatible inputs (VIH = 2.0 V min), identical timing and packaging | Better suited for mixed 5 V TTL/CMOS systems where input noise margin must match legacy logic | Select when interfacing directly to 74LS or other TTL outputs without level translation |
| SN74LV273APWRE4 | Lower VCC range (1.65–5.5 V), higher fmax (80 MHz at 3.3 V), non-automotive grade | Lacks AEC-Q100 qualification; suitable for industrial or consumer boards with tighter space constraints | Choose for cost-sensitive non-automotive designs requiring faster operation at 3.3 V |
Compared with 74HC273PW-Q100, the 74HCT273PW-Q100 offers improved input compatibility with legacy TTL sources but identical automotive qualification, while SN74LV273APWRE4 trades qualification for higher speed and broader low-voltage support - making it unsuitable for AEC-Q100-compliant deployments.

FAQ
What is the maximum clock frequency supported by the 74HC273PW-Q100?
The 74HC273PW-Q100 supports a maximum clock frequency of 30 MHz at VCC = 4.5 V and CL = 50 pF, based on its 30 ns maximum propagation delay (tpd). At 6.0 V, fmax reaches 24 MHz due to increased capacitive loading effects. These values assume proper PCB layout with minimized trace inductance and adequate local decoupling.
Can the 74HC273PW-Q100 operate reliably at 2.0 V supply voltage?
Yes - the device is fully specified from 2.0 V to 6.0 V. At 2.0 V, propagation delay increases to 150 ns (max), setup time rises to 75 ns, and output drive strength reduces to ±2 mA. All timing and DC parameters remain guaranteed across the full -40 °C to +125 °C range per AEC-Q100 Grade 1 requirements.
How does the master reset (MR) interact with the clock input?
MR is asynchronous and dominant: a LOW on MR forces all Qn outputs LOW immediately, regardless of CP state or timing. MR overrides clock activity - no clock edge is required for reset assertion or release. Release from reset (MR HIGH) does not trigger output change unless followed by a valid CP rising edge meeting setup/hold conditions.
Is the TSSOP20 package of the 74HC273PW-Q100 compatible with standard reflow profiles?
Yes - the SOT360-1 package is qualified for lead-free reflow per JEDEC J-STD-020. Peak temperature must not exceed 260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s. The side-wettable flanks enable post-reflow AOI verification of solder joint integrity, critical for automotive manufacturing traceability.
