Product details
Overview
74LVC125APW-Q100 from Nexperia is an automotive-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 -40 °C to +125 °C ambient range, and delivering ≤4.8 ns propagation delay at 3.3 V for interfacing between 3.3 V logic and legacy 5 V systems in body control modules.
For engineers reviewing the 74LVC125APW-Q100 datasheet, 74LVC125APW-Q100 pinout, 74LVC125APW-Q100 application, or 74LVC125APW-Q100 equivalent, key selection criteria include 5 V tolerance under power-down (up to 5.5 V on outputs), AEC-Q100 Grade 1 qualification, TSSOP14 package compatibility, and precise enable-controlled 3-state timing (≤7.0 ns disable time).
Technical Context
This device implements four independent non-inverting buffers, each with active-low 3-state output enable (nOE) controlling high-impedance OFF-state entry/exit. Each channel supports bidirectional 5 V tolerance-inputs accept 0–5.5 V regardless of VCC, and outputs withstand up to 5.5 V when disabled.
It operates across a wide VCC range (2.3–3.6 V), complies with JEDEC standards JESD8-5A and JESD8-C/JESD36, and features CMOS-level static power consumption (<40 μA ICC at 3.6 V) with TTL-compatible input thresholds and rail-to-rail output drive capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.3 V to 3.6 V - Enables direct interface with 2.5 V/3.3 V microcontrollers while maintaining 5 V system compatibility. |
| Input/Output Tolerance | 0 V to 5.5 V - Allows safe connection to 5 V buses without level shifters, even during power sequencing or partial power-down. |
| Propagation Delay | ≤4.8 ns at VCC = 3.0–3.6 V - Ensures deterministic timing in high-speed digital interconnects such as CAN transceiver data paths or sensor hub interfaces. |
| Enable/Disable Time | ≤7.0 ns enable, ≤6.0 ns disable at VCC = 3.0–3.6 V - Supports fast bus arbitration and dynamic bus sharing in multiplexed automotive networks. |
| Operating Temperature | -40 °C to +125 °C - Qualified for engine bay and powertrain control unit deployment per AEC-Q100 Grade 1 requirements. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Provides robust handling margin during PCB assembly and in-vehicle ESD events. |
| Output Drive | ±24 mA at VCC = 3.0 V - Sufficient to drive 50 Ω transmission lines or multiple CMOS inputs without external buffering. |
Pinout & Package
TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14 leads, 4.4 mm body width, 0.65 mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | nOE (active-low enable) | Independent per-channel 3-state control; LOW enables output, HIGH forces high-impedance state. |
| 2, 5, 9, 12 | nA (input) | Non-inverting data input; accepts 0–5.5 V regardless of VCC, enabling mixed-voltage domain bridging. |
| 3, 6, 8, 11 | nY (output) | Buffered non-inverting output; drives to VCC/GND when enabled, floats to 5.5 V max when disabled. |
| 7 | GND | Reference ground for all I/O and internal circuitry; requires low-inductance connection for signal integrity. |
| 14 | VCC | Primary supply rail; decoupling capacitor (100 nF) required within 5 mm for stable operation at full speed. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C, including temperature cycling, HTOL, and ESD stress per automotive reliability standards. |
| 5 V tolerant I/O with power-off protection | Outputs tolerate up to 5.5 V when VCC = 0 V or nOE = HIGH, eliminating need for external clamping diodes in hot-swap scenarios. |
| Low dynamic power dissipation | CPD = 12.4 pF at 3.3 V - Enables <1 mW typical dynamic power at 10 MHz toggle rate, critical for low-power body electronics. |
| JEDEC-compliant voltage interfaces | Fully compliant with JESD8-5A (2.3–2.7 V) and JESD8-C/JESD36 (2.7–3.6 V), ensuring interoperability with industry-standard logic families. |
| Side-wettable flank TSSOP option | SOT402-1 package supports automated optical inspection (AOI) of solder joints, improving manufacturing yield in automotive SMT lines. |
Applications
| Body Control Module (BCM) Signal Routing | Instrument Cluster Display Interface |
|---|---|

Use Scenario: Isolating and buffering LIN or PWM signals between MCU GPIOs and external actuators (e.g., door lock drivers, mirror controls) in harsh automotive environments. IC Role / Device Role / Timing Role: Quad buffer provides galvanic separation and drive strength boost; 3-state enables shared bus arbitration without contention. Use Value: 5 V tolerance eliminates level-shifter components; AEC-Q100 qualification ensures functional safety compliance for ASIL-B adjacent functions. |
Use Scenario: Driving segmented LED backlight control lines from a 3.3 V display controller to 5 V LED driver ICs in digital instrument clusters. IC Role / Device Role / Timing Role: Non-inverting line driver translates logic levels while maintaining signal edge integrity; fast enable/disable supports dynamic dimming updates. Use Value: ≤6.0 ns disable time prevents ghosting during rapid brightness transitions; ±24 mA drive sustains consistent LED current across temperature. |
| ADAS Camera Sensor Hub | Powertrain ECU Diagnostic Bus |
|
Use Scenario: Buffering parallel status signals (e.g., sync, frame valid, error flags) from image sensors to host processor in surround-view camera systems. IC Role / Device Role / Timing Role: Low-skew (<1.5 ns) output switching preserves timing correlation across multi-channel sensor data paths. Use Value: tsk(o) ≤1.5 ns ensures sub-pixel timing alignment; 125 °C rating supports placement near heat-generating image processors. |
Use Scenario: Enabling/disabling diagnostic communication lines (e.g., UDS K-line) between ECU main MCU and external scan tools during service mode. IC Role / Device Role / Timing Role: 3-state isolation prevents back-driving of MCU pins during tool connection; 5.5 V tolerance protects against battery transients. Use Value: Output clamp rating of ±50 mA prevents latch-up during ISO 7637-2 pulse 5a/b exposure; HBM >2000 V withstands technician ESD events. |
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 (not AEC-Q100 qualified); identical electrical specs but rated only to +85 °C. | Not suitable for under-hood or powertrain locations requiring Grade 1 thermal range. | Select only for cabin-infotainment or non-safety-critical interior modules with controlled ambient. |
| 74LVC125ABQ-Q100 | DHVQFN14 package (2.5 × 3 mm) with side-wettable flanks; same die, lower thermal resistance (θJA = 104 K/W vs. 137 K/W for TSSOP). | Better suited for space-constrained, thermally dense ECUs where board area and junction temperature are limiting. | Prefer for new designs targeting miniaturization and higher power density; requires requalification of solder process for QFN. |
Compared with SN74LVC125APWR, the 74LVC125APW-Q100 adds automotive qualification and extended temperature support; compared with 74LVC125ABQ-Q100, it trades thermal performance for easier hand-soldering and legacy TSSOP footprint compatibility.

FAQ
Is the 74LVC125APW-Q100 pin-compatible with standard 74LVC125A variants?
Yes - the TSSOP14 pinout (SOT402-1) matches industry-standard 74LVC125A footprints, including identical 14-pin numbering and functional assignment. However, the -Q100 suffix denotes automotive qualification, so industrial variants lack AEC-Q100 test reports and extended temperature validation.
Can outputs be safely driven to 5 V while VCC is at 3.3 V?
Yes - the device supports 5 V tolerant outputs in both active and 3-state modes. When enabled, outputs swing rail-to-rail (0 V to VCC); when disabled (nOE HIGH), outputs tolerate up to 5.5 V, allowing connection to 5 V buses without risk of damage or leakage current.
What is the maximum clock/data frequency supported by this buffer?
The device has no internal clock; its usable frequency depends on propagation delay and load. With 50 pF load and 3.3 V supply, tpd ≤4.8 ns supports clean signal transmission up to ~100 MHz for short traces, assuming proper termination and layout to minimize reflections.
Does the TSSOP14 package require special PCB layout considerations?
Yes - maintain ≥0.2 mm solder mask dam between pins to prevent bridging, use thermal relief on GND/VCC pads, and place a 100 nF ceramic decoupling capacitor within 5 mm of pin 14 (VCC). Avoid routing high-speed signals under the package to reduce crosstalk.
