Product details
Overview
74LVC273D-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 up to 5.5 V input tolerance, and qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C) for engine control and ADAS domain controllers.
For engineers reviewing the 74LVC273D-Q100 datasheet, 74LVC273D-Q100 pinout, 74LVC273D-Q100 application, or 74LVC273D-Q100 equivalent, key selection criteria include propagation delay (1.5 ns min, 10.5 ns max at 3.0–3.6 V), set-up/hold timing (1.0 ns su / 1.0 ns h), output drive capability into 50 Ω transmission lines, Schmitt-trigger inputs for noise immunity, and SO20 package compatibility with legacy PCB footprints.
Technical Context
This device implements eight independent D-type latches synchronized by a single LOW-to-HIGH clock edge on CP, with MR asserting all Qn outputs LOW regardless of CP or Dn state. Its CMOS architecture enables rail-to-rail logic swing and low static current (≤40 μA at VCC = 3.6 V).
Schmitt-trigger inputs tolerate slow rise/fall times and reject noise; overvoltage-tolerant inputs accept 5.5 V signals while powered from 1.2–3.6 V, enabling level translation between 3.3 V and 5 V subsystems in automotive gateways and body control modules.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC273QPWRQ1 | TSSOP20 package (SOT360-1); identical electrical specs but 4.4 mm body width and 0.65 mm pitch | Better thermal performance at +125 °C ambient due to lower junction-to-air resistance; preferred for compact PCB layouts | Select when board space is constrained and AOI inspection of fine-pitch leads is available |

FAQ
What is the maximum clock frequency supported by the 74LVC273D-Q100?
The 74LVC273D-Q100 supports a maximum clock frequency of 150 MHz at VCC = 3.0–3.6 V and −40 °C to +85 °C ambient, and 150 MHz at −40 °C to +125 °C. At VCC = 2.7 V, fmax reaches 150 MHz across both temperature ranges; at VCC = 2.3–2.7 V, it operates up to 100 MHz at +125 °C. These values are guaranteed by design and verified per JEDEC JESD8-C/JESD36 standards.
Can the 74LVC273D-Q100 safely interface with 5 V logic outputs?
Yes - its inputs are overvoltage tolerant up to 5.5 V regardless of VCC (1.2–3.6 V), allowing direct connection to 5 V microcontrollers, CAN transceivers, or sensor outputs without external level-shifting components. This capability is validated per JESD8-7A, JESD8-5A, and JESD8-C standards and confirmed in the datasheet's Recommended Operating Conditions table.
Does the SO20 package (SOT163-1) support automatic optical inspection (AOI)?
No - unlike the DHVQFN20 (SOT764-1) variant, the SO20 package does not feature side-wettable flanks and is not optimized for AOI of solder joints. It relies on traditional X-ray or ICT verification. The datasheet explicitly cites AOI capability only for the BQ package version, confirming SO20's suitability for cost-driven, non-AOI production lines.
How does the master reset (MR) interact with the clock signal?
MR is asynchronous and active-LOW: when MR = LOW, all Qn outputs force LOW immediately, overriding any CP edge or Dn state. When MR returns HIGH, the next CP rising edge samples Dn and updates Qn. Recovery time trec is specified as 2.0 ns minimum at VCC = 3.0–3.6 V, ensuring predictable re-synchronization after reset release.
