Product details
Overview
74LVC273PW-Q100 from Nexperia is an automotive-grade octal positive-edge-triggered D-type flip-flop with asynchronous master reset (MR), operating from 1.2 V to 3.6 V supply, supporting mixed-voltage interfacing (5.5 V-tolerant inputs), and qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C) for use in engine control units and ADAS domain controllers.
For engineers reviewing the 74LVC273PW-Q100 datasheet, 74LVC273PW-Q100 pinout, 74LVC273PW-Q100 application, or 74LVC273PW-Q100 equivalent, key selection considerations include propagation delay (1.5 ns min at 3.0–3.6 V), output skew (≤1.5 ns), Schmitt-trigger input tolerance for slow edges, and TSSOP20 package compatibility with automated optical inspection (AOI) via side-wettable flanks.
Technical Context
This device implements eight independent edge-triggered D flip-flops sharing a common clock (CP) and active-low master reset (MR). Each Qn output captures the corresponding Dn input state on the LOW-to-HIGH transition of CP, provided setup (1.0 ns min at 3.0–3.6 V) and hold (1.0 ns min) timing requirements are met.
MR forces all outputs LOW regardless of CP or data states, enabling synchronous system initialization. Inputs feature Schmitt-trigger action and overvoltage tolerance up to 5.5 V, allowing direct interface between 3.3 V logic and legacy 5 V subsystems without level shifters.
Key Specifications

| Supply Voltage Range | 1.2 V to 3.6 V - Enables operation across low-power microcontroller I/O domains and battery-backed automotive subsystems. |
| Input Voltage Tolerance | Up to 5.5 V - Permits direct connection to 5 V buses without external clamping or translation circuitry. |
| Propagation Delay (CP to Qn) | 1.5 ns (min) at VCC = 3.0–3.6 V - Supports high-speed sampling in time-critical control loops. |
| Maximum Clock Frequency | 150 MHz (guaranteed at −40 °C to +125 °C) - Sufficient for real-time sensor data latching in powertrain modules. |
| Output Skew | ≤1.5 ns - Ensures deterministic timing alignment across all eight outputs in synchronized data capture. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets automotive robustness requirements for assembly and field operation. |
| Ambient Temperature Range | −40 °C to +125 °C - Qualified for under-hood and transmission-control applications per AEC-Q100 Grade 1. |

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 |
|---|---|---|---|
| SN74LVC273QPWRQ1 | TI variant with identical pinout and electrical specs; differs in test methodology and qualification documentation scope. | Approved for GM-specific automotive programs; lacks Nexperia's DHVQFN20 package option. | Select when sourcing from TI-authorized channels or aligning with GM engineering standards. |
| 74AUP273GQ-Q100 | Lower static current (0.04 μA vs. 0.1 μA) and extended VCC range (0.8–3.6 V), but reduced fmax (125 MHz at +125 °C). | Better suited for ultra-low-power always-on domains (e.g., vehicle wake-up logic), not high-speed control loops. | Prefer for battery-backed modules where quiescent current dominates thermal budget over speed. |

FAQ
What is the minimum setup time required for reliable operation at 3.3 V?
The minimum setup time (tsu) is 1.0 ns at VCC = 3.0–3.6 V and −40 °C to +125 °C ambient, measured from Dn input transition to the LOW-to-HIGH CP edge. This value is guaranteed across the full automotive temperature range and ensures deterministic sampling without metastability in ECU timing paths.
Can the 74LVC273PW-Q100 drive 50 Ω transmission lines directly?
Yes - the device specifies output drive capability for 50 Ω transmission lines at +85 °C, verified under load conditions matching industry-standard test circuits (Fig. 6, Table 9). At VCC = 3.3 V, it delivers ≥24 mA sink/source current, enabling direct connection to controlled-impedance traces without external line drivers in ADAS sensor interfaces.
Does the TSSOP20 package support reflow soldering per J-STD-020?
Yes - the SOT360-1 (TSSOP20) package is qualified for standard lead-free reflow profiles per J-STD-020, with peak temperature up to 260 °C. Its side-wettable flanks are specifically engineered for post-reflow AOI verification, satisfying IPC-A-610 Class 3 requirements for automotive electronics assembly.
How does the master reset (MR) interact with clock and data during power-up?
MR is asynchronous and active LOW: when asserted, it forces all Qn outputs LOW immediately, overriding any CP edge or Dn state. During power-up, asserting MR until VCC stabilizes above 1.2 V ensures known initial states across all eight outputs, preventing spurious actuations in safety-critical outputs like fuel injector enables or brake control signals.
