Product details
Overview
74LVC126APW-Q100 from Nexperia is an automotive-qualified quad buffer/line driver with 3-state outputs, 5 V tolerant I/O, and operation from 1.2 V to 3.6 V supply. It features Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and AEC-Q100 Grade 1 qualification (−40 °C to +125 °C). Used in mixed-voltage automotive signal routing, such as CAN/LIN interface level translation or ECU sensor bus buffering.
For engineers reviewing the 74LVC126APW-Q100 datasheet, 74LVC126APW-Q100 pinout, 74LVC126APW-Q100 application, or 74LVC126APW-Q100 equivalent, key selection criteria include 5 V tolerance on 3.3 V rails, tpd ≤ 6.0 ns at 3.3 V, IOFF-enabled hot-swap safety, and TSSOP14 package compatibility with AOI-capable SMT lines.
Technical Context
This device implements four independent non-inverting buffers, each with active-HIGH output enable (nOE) controlling high-impedance OFF-state. Schmitt-trigger inputs accept slow-rising signals (Δt/ΔV up to 20 ns/V at 1.65 V), enabling robust interfacing with mechanical switches or noisy sensors.
The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±50 mA-critical for live-insertion in automotive domain controllers. Input voltage range extends to 5.5 V regardless of VCC, allowing direct connection to legacy 5 V logic without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.2 V to 3.6 V - supports ultra-low-power microcontrollers and wide-battery automotive rails |
| Input voltage tolerance | 0 V to 5.5 V - enables direct interfacing with 5 V peripherals without external translators |
| Propagation delay | 1.0 ns to 6.0 ns (VCC = 3.0–3.6 V) - ensures timing-critical signal integrity in fast control loops |
| IOFF leakage | ±10 μA max at VCC = 0 V - prevents damaging backfeed during partial system power-down |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive environments per AEC-Q100 Grade 1 |
| ESD rating | HBM > 2000 V, CDM > 1000 V - meets stringent automotive board-level ESD immunity requirements |
| Output drive | ±24 mA at VCC = 3.0 V - sufficient to drive 50 pF loads across full temperature range |
Pinout & Package
TSSOP14 plastic thin shrink small outline package (SOT402-1); 14-lead, 4.4 mm body width; side-wettable flanks support automated optical inspection (AOI) of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | nOE (output enable) | Active-HIGH control per buffer; drives output to high-impedance when LOW |
| 2, 5, 9, 12 | nA (data input) | Non-inverting input with Schmitt-trigger threshold; accepts 0–5.5 V regardless of VCC |
| 3, 6, 8, 11 | nY (data output) | 3-state buffered output; 5 V tolerant, ±24 mA drive capability |
| 7 | GND | Ground reference (0 V); substrate tie point not electrically required but may be floated or grounded |
| 14 | VCC | Primary supply rail (1.2–3.6 V); powers internal logic and output stages |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation in automotive powertrain and chassis modules |
| 5 V tolerant I/O | Inputs and outputs withstand 5.5 V while powered from 1.2–3.6 V - eliminates discrete level shifters |
| IOFF partial power-down | Outputs disable safely at VCC = 0 V, preventing back-current damage during hot-swap or sleep mode |
| Schmitt-trigger inputs | Hysteresis ≥ 0.35 V at 3.3 V - rejects noise on long traces or mechanical switch bounce |
| TSSOP14 with side-wettable flanks | Enables AOI-based solder-joint verification - critical for zero-defect automotive manufacturing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC126AQPWRQ1 | TI variant; identical 5 V tolerance, IOFF, and AEC-Q100 Grade 1, but uses VSS/VDD pinout (not GND/VCC) and lacks side-wettable flanks | Requires rework of PCB land pattern; no AOI support for solder joints | Select if TI ecosystem alignment or existing TI design reuse is prioritized over AOI manufacturability |
| 74LVC125APW-Q100 | Nexperia pin-compatible variant with active-LOW nOE (instead of active-HIGH); otherwise identical specs and package | Requires inverted enable logic in firmware/hardware; unsuitable where active-HIGH control is fixed | Choose only when system-level enable polarity matches - no electrical or thermal trade-offs |
Compared with SN74LVC126AQPWRQ1, the 74LVC126APW-Q100 offers superior process control via AOI-ready side-wettable flanks; versus 74LVC125APW-Q100, it provides native active-HIGH enable logic, eliminating need for external inverters in most automotive MCU GPIO configurations.

FAQ
What is the maximum input voltage the 74LVC126APW-Q100 can tolerate when VCC = 1.2 V?
The device tolerates input voltages from −0.5 V to +5.5 V regardless of VCC level, per Table 4 (Limiting Values) and Table 5 (Recommended Operating Conditions). This 5 V tolerance is maintained even at minimum 1.2 V supply, enabling safe interfacing with higher-voltage peripherals without clamping diodes or level shifters.
Does the 74LVC126APW-Q100 support hot-plug operation in automotive ECUs?
Yes - its IOFF circuitry actively disables outputs and limits backflow current to ±10 μA when VCC = 0 V (Table 9, Static Characteristics), satisfying hot-swap requirements in domain controllers. This prevents damage during live insertion or partial power-down sequences common in vehicle gateway modules.
How does the Schmitt-trigger input improve noise immunity in automotive environments?
Schmitt-trigger inputs provide ≥ 0.35 V hysteresis at 3.3 V (Table 6), rejecting transient noise up to that amplitude. Combined with input transition rate support up to 20 ns/V at 1.65 V (Table 5), this suppresses EMI-induced false triggering on long harness runs or near high-current switching nodes in engine bays.
Is the TSSOP14 package of the 74LVC126APW-Q100 compatible with standard reflow profiles?
Yes - the SOT402-1 package is qualified for standard lead-free reflow (J-STD-020), with peak temperature up to 260 °C. Its side-wettable flanks are designed for compatibility with AOI systems using standard red-light illumination and image processing algorithms used in Tier-1 automotive SMT lines.
