Product details
Overview
74LVC125AD-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 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 automotive infotainment bus interfacing between 3.3 V logic and legacy 5 V peripherals. It features four independent enable-controlled buffers, ±24 mA drive capability at 3.0 V, and guaranteed operation from –40 °C to +125 °C.
For engineers reviewing the 74LVC125AD-Q100 datasheet, 74LVC125AD-Q100 pinout, 74LVC125AD-Q100 application, or 74LVC125AD-Q100 equivalent, this device is selected for robust level-shifting in automotive body control modules, ADAS sensor interface hubs, and CAN/LIN subsystem signal conditioning where 5 V tolerance, low static current (<10 μA), and SO14 package compatibility are critical.
Technical Context
This IC implements four independent CMOS-based non-inverting buffers, each with active-low 3-state output control (nOE). Each channel accepts input voltages up to 5.5 V regardless of VCC (2.3–3.6 V), enabling seamless interfacing between mixed-voltage domains without external level shifters.
Propagation delay is specified down to 1.0 ns (typical at VCC = 3.3 V), with enable/disable times under 7.0 ns across temperature, and output skew ≤1.5 ns - ensuring tight timing alignment in synchronous data routing applications such as SPI or parallel sensor readout buses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.3 V to 3.6 V - enables direct use with 2.5 V/3.3 V automotive microcontrollers while maintaining 5 V I/O tolerance |
| Input Voltage Range | –0.5 V to 5.5 V - supports hot-plug-safe interfacing with 5 V legacy peripherals without clamping diodes or external protection |
| Output Drive | ±24 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple TTL loads in distributed automotive networks |
| Propagation Delay | 1.0–6.0 ns (VCC = 3.0–3.6 V) - ensures sub-10 ns timing margins for 50 MHz+ digital control signals in BCMs and gateway ECUs |
| Operating Temperature | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain-adjacent placement |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive ESD immunity requirements for assembly and field operation |
| Static Current | ≤40 μA at VCC = 3.6 V - minimizes quiescent power in always-on vehicle subsystems like door module wake-up logic |
Pinout & Package
74LVC125AD-Q100 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, JEDEC MS-012 compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | nOE (active-low enable) | Independent 3-state control per buffer; LOW enables output, HIGH forces high-impedance - enables bus arbitration and multi-drop sharing |
| 2, 5, 9, 12 | nA (input) | Non-inverting data input; accepts 0–5.5 V regardless of VCC - eliminates need for external level translators in mixed-voltage systems |
| 3, 6, 8, 11 | nY (output) | Buffered non-inverting output; drives to VCC or GND when enabled, floats to 5.5 V max when disabled - safe for hot-swap and back-driving |
| 7 | GND | Reference ground plane; decoupling capacitor must be placed adjacent to pin 7 for noise suppression in automotive EMI environments |
| 14 | VCC | Primary power rail; requires local 100 nF ceramic decoupling; voltage range 2.3–3.6 V defines logic thresholds and drive strength |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from –40 °C to +125 °C ambient, including thermal cycling and humidity testing per JESD47 |
| 5 V tolerant I/O | Inputs and outputs withstand up to 5.5 V even at VCC = 2.3 V - enables direct connection to 5 V sensors, displays, and legacy ECUs |
| Low dynamic power | CPD = 12.4 pF (VCC = 3.3 V) - reduces switching power in high-frequency clock distribution or data bus buffering |
| Side-wettable flanks not applicable | SO14 package (SOT108-1) lacks side-wettable flanks - AOI inspection relies on top-surface solder joint visibility only |
| JEDEC-compliant voltage standards | Complies with JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) - ensures interoperability across voltage-tiered automotive subsystems |
Applications

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 SO14 pinout and electrical specs except temp range | Not suitable for under-hood or safety-critical locations; acceptable for cabin-only infotainment modules | Select when cost sensitivity outweighs automotive qualification requirements and ambient temperature stays below 85 °C |
| 74LVC125ABQ-Q100 | DHVQFN14 package (2.5 × 3 mm); same AEC-Q100 Grade 1 rating and electrical performance; no leads, side-wettable flanks | Better thermal dissipation and smaller footprint; requires rework-capable SMT process and AOI-compatible stencil design | Select for space-constrained ADAS modules where board area and thermal resistance are prioritized over through-hole prototyping ease |
Compared with SN74LVC125APWR, the 74LVC125AD-Q100 adds automotive qualification and extended temperature support but shares identical logic behavior and pinout; versus 74LVC125ABQ-Q100, it trades miniaturization and thermal performance for SO14 manufacturability and legacy test fixture compatibility.

FAQ
Can 74LVC125AD-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/VIL thresholds fall outside specification, and output drive strength degrades significantly - confirmed by static characteristics in Table 6 where VCC = 1.65–1.95 V is supported only for JESD8-7A compliance, not full functionality.
What is the maximum allowable output voltage when the device is disabled?
When in 3-state (high-impedance) mode, outputs tolerate up to +5.5 V regardless of VCC level, as defined in Table 4 (Limiting Values) and confirmed in Section 1 General Description: "When disabled, up to 5.5 V can be applied to the outputs." This enables safe back-driving in hot-swap scenarios.
Does the SO14 package support automatic optical inspection (AOI)?
The SO14 (SOT108-1) package used in 74LVC125AD-Q100 does not feature side-wettable flanks. AOI relies solely on top-surface solder joint imaging; unlike DHVQFN variants, it lacks solder fillet geometry for lateral joint verification - standard vision-based AOI remains effective but cannot assess solder volume under leads.
How does the enable pin behavior affect bus contention in multi-driver configurations?
Each nOE pin controls one buffer independently. When any nOE is HIGH, its corresponding nY output enters high-impedance state, electrically disconnecting that driver from the bus. This allows multiple 74LVC125AD-Q100 devices to share a common line without contention, provided only one nOE is LOW at any time - verified by functional description Table 3 and pin description Table 2.
