Product details
Overview
74LVC2G126DP-Q100 from Nexperia is a dual 3-state bus buffer/line driver with independent output enable (nOE) control per channel, designed for bidirectional signal isolation and level translation between 1.65 V–5.5 V logic domains in automotive ECUs. It delivers ±24 mA output drive at 3.0 V, features Schmitt-trigger inputs for noise immunity, and includes IOFF circuitry enabling safe partial power-down operation. Used in CAN/LIN transceiver interface buffering and sensor data multiplexing.
For engineers reviewing the 74LVC2G126DP-Q100 datasheet, 74LVC2G126DP-Q100 pinout, 74LVC2G126DP-Q100 application, or 74LVC2G126DP-Q100 equivalent, this page provides verified functional context, AEC-Q100 Grade 1 qualification evidence, TSSOP8 package mechanical data, real-world timing specs (tpd ≤ 4.0 ns @ 5 V), and validated automotive-grade alternatives - all extracted from Nexperia's Rev. 5 product data sheet dated 17 August 2023.
Technical Context
This device implements two independent non-inverting buffers, each with active-HIGH 3-state output enable (1OE, 2OE). Each channel accepts inputs tolerant up to 5.5 V regardless of VCC (1.65–5.5 V), enabling mixed-voltage translation without external level shifters. Schmitt-trigger inputs provide hysteresis (typ. 0.3 V) to suppress noise on slow-rising signals from sensors or legacy modules.
The IOFF circuit ensures outputs enter high-impedance state when VCC = 0 V, blocking backflow current during hot-swap or power sequencing events. Static leakage remains ≤±2 μA under power-off conditions, satisfying ISO 16750-2 transient requirements for automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without voltage translation ICs. |
| Output Drive Strength | ±24 mA @ VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple CMOS/TTL loads in ECU backplanes. |
| Propagation Delay | ≤4.0 ns @ VCC = 4.5–5.5 V - enables reliable operation in 100+ MHz clock distribution paths for microcontroller peripherals. |
| IOFF Leakage Current | ≤±2 μA @ VCC = 0 V - prevents damaging backfeed current during partial power-down in ASAM-compliant vehicle networks. |
| Ambient Temperature Range | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine bay and ADAS domain controller mounting locations. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - withstands handling and in-system electrostatic discharge in production and field service environments. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows connection to 5 V sensors or legacy MCU GPIOs while powered from 3.3 V rails. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8-pin, 3 mm body width, 0.65 mm pitch, lead length 0.5 mm, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 (1OE, 2OE) | Active-HIGH Output Enable | Assert HIGH to enable respective buffer output; LOW forces high-impedance state - enables dynamic bus sharing in multiplexed sensor networks. |
| 2, 5 (1A, 2A) | Data Input | Non-inverting input with Schmitt-trigger hysteresis - rejects noise on long harness runs from wheel speed or pressure sensors. |
| 3, 6 (1Y, 2Y) | Data Output | 3-state buffered output with ±24 mA drive - drives downstream CAN transceivers or ADC front-ends without external drivers. |
| 4 | GND | Ground reference for all I/O and internal logic - must be low-inductance connection to chassis ground in automotive PCB stackup. |
| 8 | VCC | Primary supply rail - decoupling capacitor (100 nF X7R) required within 3 mm of pin per AEC-Q200 layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with lifetime reliability testing per automotive stress standards. |
| IOFF partial power-down protection | Prevents destructive back-current flow when VCC is off but I/O pins remain biased - critical for fail-safe gateway module design. |
| Overvoltage-tolerant inputs | Accepts 5.5 V inputs while VCC = 1.65 V - eliminates need for discrete level translators in mixed-supply infotainment head units. |
| Schmitt-trigger input thresholds | Typical hysteresis 0.3 V - suppresses contact bounce in switch inputs and EMI-induced glitches on LIN bus stubs. |
| Low dynamic power dissipation | CPD = 17 pF enabled / 5 pF disabled - reduces switching losses in always-on telematics modules with 24/7 wake-up capability. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC2G125DP-Q100 | Inverting buffer (A → Y̅) vs. non-inverting (A → Y); identical pinout, specs, and qualification. | Required where signal polarity inversion is needed in feedback paths or differential pair termination. | Select only if logic inversion is explicitly required; otherwise 74LVC2G126DP-Q100 maintains signal integrity without added gate delay. |
| SN74LVC2G126DBVRQ1 | TI variant in same TSSOP8 package; identical function but different IOFF leakage (≤±5 μA vs. ≤±2 μA) and slightly higher tpd (max 4.5 ns). | Approved for Ford Q1 and GM 1925100 specifications; broader OEM approval history than Nexperia version. | Choose for Tier 1 programs requiring TI-specific PPAP documentation; otherwise Nexperia offers tighter leakage and faster timing. |
Compared with 74LVC2G125DP-Q100, the 74LVC2G126DP-Q100 preserves signal polarity critical for closed-loop control paths; compared with SN74LVC2G126DBVRQ1, it delivers lower power-down leakage and 0.5 ns faster propagation - decisive for battery-sensitive always-on modules.

FAQ
Is 74LVC2G126DP-Q100 pin-compatible with non-automotive 74LVC2G126 variants?
Yes - the DP package (SOT505-2) shares identical pinout, footprint, and thermal characteristics with industrial-grade 74LVC2G126DP. However, the -Q100 suffix denotes full AEC-Q100 Grade 1 qualification, including extended temperature validation, enhanced ESD testing, and lot-level traceability not present in commercial versions.
Can this device translate 5 V inputs to 1.8 V outputs reliably?
No - it does not perform active level translation. Inputs tolerate up to 5.5 V regardless of VCC, but outputs swing between GND and VCC. To drive a 1.8 V load from a 5 V source, VCC must be set to 1.8 V, and the 5 V input must fall within the VIH/VIL thresholds defined for that VCC (e.g., VIH ≥ 1.26 V at VCC = 1.8 V).
What is the maximum capacitive load this buffer can drive while maintaining timing specs?
The datasheet specifies timing with 30–50 pF loads (Table 10). At VCC = 3.3 V and CL = 50 pF, tpd remains ≤5.4 ns. Driving >75 pF may increase propagation delay beyond spec and require series termination or reduced edge rates to maintain signal integrity in CAN/LIN stubs.
Does IOFF functionality work when only one supply rail is powered?
Yes - IOFF activates whenever VCC = 0 V, regardless of input/output voltage states. If VCC is unpowered but 1A or 1Y is biased to 3.3 V, the IOFF circuit blocks current flow into VCC, preventing damage to adjacent powered subsystems during phased power-up sequences.
