Product details
Overview
74LVC125ABQ-Q100 from Nexperia is an automotive-grade quad non-inverting 3-state buffer/line driver with 5 V tolerant inputs and outputs, operating from 2.3 V to 3.6 V supply, supporting -40 °C to +125 °C ambient range, and qualified per AEC-Q100 Grade 1 for engine control, body electronics, and ADAS domain controllers.
For engineers reviewing the 74LVC125ABQ-Q100 datasheet, 74LVC125ABQ-Q100 pinout, 74LVC125ABQ-Q100 application, or 74LVC125ABQ-Q100 equivalent, this device delivers precise level translation between 3.3 V logic domains and legacy 5 V subsystems while maintaining low dynamic power and robust ESD immunity in space-constrained automotive PCB layouts.
Technical Context
This IC implements four independent non-inverting buffers, each with active-low 3-state enable (nOE) controlling high-impedance output (Z) states. Each channel supports bidirectional 5 V tolerance on both inputs and outputs - enabling safe interfacing with 5 V peripherals even when powered at 2.3 V–3.6 V.
Its CMOS architecture ensures rail-to-rail input thresholds (VIH = 2.0 V min at VCC = 3.0 V; VIL = 0.8 V max), propagation delays as low as 2.5 ns (typ, VCC = 3.3 V), and output skew ≤1.0 ns (max) across channels - critical for synchronized signal routing in multi-sensor automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.3 V to 3.6 V - enables direct integration into 3.3 V automotive domains without level-shifter overhead. |
| Input/Output Tolerance | Up to 5.5 V - allows safe connection to 5 V microcontrollers, sensors, or legacy CAN transceivers without external clamping. |
| Propagation Delay | 2.5 ns (typ, VCC = 3.3 V) - supports >100 MHz data throughput in bus buffering applications like LIN or SPI peripheral expansion. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets stringent automotive board-level ESD requirements per ISO 10605. |
| Operating Temperature | -40 °C to +125 °C - certified for under-hood and transmission-control module environments. |
| Power Dissipation | 500 mW (max, Tamb ≤125 °C) - accommodates thermal constraints in DHVQFN14 package with side-wettable flanks. |
| Output Drive | ±24 mA (VOH/VOL @ VCC = 3.0 V) - drives 50 Ω transmission lines or multiple CMOS/TTL loads directly. |
Pinout & Package
DHVQFN14 (SOT762-1) package: 2.5 × 3.0 × 0.85 mm body, no leads, side-wettable flanks for AOI-compatible solder joint inspection, thermal-enhanced construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | nOE (active-low enable) | Independent 3-state control per buffer; LOW enables output, HIGH forces high-Z - enables time-multiplexed bus sharing. |
| 2, 5, 9, 12 | nA (data input) | Non-inverting input; accepts 0–5.5 V signals regardless of VCC - eliminates need for external voltage translators. |
| 3, 6, 8, 11 | nY (data output) | Buffered non-inverting output; 5 V tolerant in all states - safely interfaces with mixed-voltage backplanes. |
| 7 | GND | Ground reference; electrically isolated thermal pad beneath package - requires floating or GND connection per layout guidelines. |
| 14 | VCC | Core supply input; decoupling capacitor placement adjacent to Pin 14 is mandatory for noise suppression in automotive EMC environments. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125 °C ambient - eliminates requalification effort for Tier 1 ECU designs. |
| 5 V tolerant I/O (up to 5.5 V) | Enables direct connection to 5 V sensors or microcontrollers without external resistors or translators - reduces BOM count and layout area. |
| DHVQFN14 with side-wettable flanks | Supports automated optical inspection of solder joints - improves manufacturing yield and field-reliability in high-volume automotive production. |
| Low ICC (≤40 μA max) | Minimizes quiescent current in always-on vehicle networks (e.g., body control modules), extending battery standby life. |
| JEDEC-compliant voltage standards | Fully compliant with JESD8-5A (2.3–2.7 V) and JESD8-C/JESD36 (2.7–3.6 V) - ensures interoperability across global semiconductor supply chains. |
Applications
| Engine Control Unit (ECU) Signal Conditioning | Body Control Module (BCM) Bus Expansion |

Use Scenario: Isolating and buffering sensor interface signals (e.g., crankshaft position, knock sensor) before ADC sampling in a 3.3 V MCU domain. IC Role / Device Role / Timing Role: Non-inverting buffer with 5 V tolerant inputs accepts raw 5 V analog sensor outputs; 3-state capability enables shared diagnostic bus access. Use Value: Eliminates discrete level-shifters and reduces signal path delay to <3 ns - preserving timing margins for real-time engine timing calculations. |
Use Scenario: Expanding GPIO count for door lock actuators, window lift motors, and interior lighting controls in a centralized BCM. IC Role / Device Role / Timing Role: Quad line driver routes MCU GPIOs to multiple 5 V relay drivers; 3-state outputs prevent contention during firmware updates. Use Value: Delivers ±24 mA drive per channel - directly switches automotive-rated relays without external transistors, cutting component count by 4× per buffer bank. |
| ADAS Camera Interface Buffering | Infotainment System Level Translation |
|
Use Scenario: Driving parallel pixel data lanes from image sensor to SoC MIPI bridge in ADAS camera modules. IC Role / Device Role / Timing Role: Low-skew (<1.0 ns) quad buffer synchronizes clock and data lines; 5 V tolerance handles sensor-side pull-ups. Use Value: Output skew guarantee prevents inter-lane timing misalignment - avoids pixel corruption in 1080p@30fps video streams. |
Use Scenario: Interfacing legacy 5 V audio codecs or display timing controllers with modern 3.3 V application processors. IC Role / Device Role / Timing Role: Bidirectional voltage translator for I²C/SPI control buses; 3-state enables hot-plug detection and bus arbitration. Use Value: Supports 0–5.5 V input range while consuming <40 μA ICC - maintains low-power audio subsystem operation during sleep mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC125APWR | Industrial grade (-40 °C to +85 °C); no AEC-Q100 qualification; identical electrical specs and pinout. | Not suitable for under-hood or safety-critical modules; limited to cabin infotainment or non-automotive industrial use. | Select only if automotive qualification is unnecessary and cost sensitivity outweighs long-term reliability requirements. |
| 74LVC125APW-Q100 | TSSOP14 package (SOT402-1); same AEC-Q100 Grade 1 rating and electrical performance; 4.4 mm body width vs. 3.0 mm. | Less suitable for ultra-dense ADAS camera PCBs due to larger footprint and no side-wettable flanks for AOI. | Prefer when existing assembly lines are optimized for TSSOP handling or thermal demands permit larger package size. |
Compared with SN74LVC125APWR and 74LVC125APW-Q100, the 74LVC125ABQ-Q100 uniquely combines AEC-Q100 Grade 1 compliance, DHVQFN14's AOI-ready construction, and the smallest footprint - making it the only choice for next-generation compact, high-reliability automotive ECUs requiring zero visual solder defects.

FAQ
Can 74LVC125ABQ-Q100 operate with a 1.8 V supply?
No. The recommended operating supply range is strictly 2.3 V to 3.6 V per Table 5. At 1.8 V, VIH and VOL specifications fall outside guaranteed limits, risking logic misreads and excessive output leakage. Operation below 2.3 V violates JEDEC JESD8-5A compliance and voids AEC-Q100 qualification coverage.
What is the maximum allowable voltage on nY pins when the device is unpowered (VCC = 0 V)?
Per Table 4, the absolute maximum output voltage is -0.5 V to +6.5 V regardless of VCC state. However, with VCC = 0 V, IOFF (power-off leakage) is specified at ±20 μA max when VO = 5.5 V - confirming safe 5 V application to outputs during power-down sequences common in automotive wake-up protocols.
Does the DHVQFN14 thermal pad require soldering to ground?
No. Per Figure 5 footnote (1), the exposed pad has no electrical or mechanical requirement to be soldered. If soldered, it must remain electrically floating or connect to GND - never to VCC or signal nets - to avoid compromising thermal performance or introducing noise coupling paths in sensitive analog-adjacent automotive layouts.
How does the 3-state disable time (tdis) impact CAN FD bus arbitration timing?
tdis is 6.0 ns max (VCC = 3.3 V, -40 °C to +125 °C), far below CAN FD's minimum bit time (e.g., 125 ns at 8 Mbps). This ensures glitch-free bus release during controller-initiated arbitration pauses, preventing false dominant bits that could corrupt frame synchronization in multi-node vehicle networks.
