Product details
Overview
74LVC273BQ-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 150 MHz max clock frequency at 3.0–3.6 V, and qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C) for use in engine control units and ADAS domain controllers.
For engineers reviewing the 74LVC273BQ-Q100 datasheet, 74LVC273BQ-Q100 pinout, 74LVC273BQ-Q100 application, or 74LVC273BQ-Q100 equivalent, key selection considerations include its overvoltage-tolerant 5.5 V inputs, Schmitt-trigger input hysteresis for noise immunity, DHVQFN20 package with side-wettable flanks for AOI, 1.5 ns minimum clock pulse width, and 1.0 ns output skew across all eight outputs.
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 VCC = 3.0–3.6 V) and hold (1.0 ns min) timing requirements are met.
MR forces all outputs low asynchronously, overriding clock and data. Inputs tolerate up to 5.5 V regardless of VCC (1.2–3.6 V), enabling mixed-voltage translation between 3.3 V logic and legacy 5 V systems. Schmitt-trigger inputs ensure robust operation with slow-rising signals typical in automotive harness environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.2 V to 3.6 V - Enables direct integration into low-voltage automotive microcontroller domains without level-shifting. |
| Max Clock Frequency | 150 MHz at VCC = 3.0–3.6 V - Supports high-speed data latching in CAN FD gateway buffers and sensor preprocessing pipelines. |
| Input Overvoltage Tolerance | 5.5 V - Allows safe interfacing with 5 V sensors or legacy ECUs while powered from 3.3 V or lower rails. |
| Propagation Delay (CP to Q) | 1.5 ns (min), 8.2 ns (max) at VCC = 3.0–3.6 V - Ensures deterministic timing in synchronous control loops with tight jitter budgets. |

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 | Same logic function and AEC-Q100 Grade 1 rating, but in TSSOP20 (SOT360-1); no side-wettable flanks; 0.65 mm pitch vs. BQ's 0.5 mm. | Lacks AOI-compatible package; higher thermal resistance (10.0 mW/K derating above 100 °C vs. 12.9 mW/K for BQ). | Preferred where board space allows larger footprint and AOI is not mandated by production line requirements. |
| 74AUP273GT,115 | Lower static current (0.9 μA typ vs. 0.1 μA), wider VCC range (0.8–3.6 V), but only industrial temp (−40 °C to +85 °C); no AEC-Q100 qualification. | Not suitable for under-hood automotive use; lacks MR-to-Q propagation delay spec at +125 °C. | Applicable only in cabin-infotainment or non-safety-critical subsystems where extended temperature range is unnecessary. |

FAQ
What is the minimum clock pulse width required for reliable operation?
The minimum clock pulse width (tW) is 1.5 ns at VCC = 3.0–3.6 V and −40 °C to +125 °C, verified per Table 7 of the datasheet. This ensures sufficient time for internal metastability resolution and guarantees correct D-to-Q capture without race conditions, even under worst-case voltage and temperature conditions.
Can the 74LVC273BQ-Q100 interface directly with 5 V TTL logic?
Yes - all inputs are overvoltage tolerant up to 5.5 V regardless of VCC (1.2–3.6 V), and output drive strength supports direct connection to TTL loads. The device meets JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36, confirming compatibility with 5 V TTL input thresholds and fan-out requirements.
Is the thermal pad on the DHVQFN20 package required to be soldered to ground?
No - the exposed thermal pad (terminal 1 index area) has no electrical requirement. Per datasheet Section 5.1, it may remain floating or be connected to GND if soldered; however, doing so improves thermal performance by ~15 % in high-power-density layouts, though it is not mandatory for functional operation.
How does the Schmitt-trigger input improve noise immunity in automotive environments?
Schmitt-trigger inputs provide hysteresis of ≥0.3 V at VCC = 3.3 V, meaning the input threshold rises to ~2.0 V for HIGH detection and falls to ~1.7 V for LOW detection. This prevents multiple toggling due to slow-rising signals or EMI-induced ringing on long harness traces - a common issue in 12 V vehicle electrical systems.
