Product details
Overview
CLVC2G125IDCURQ1 from Texas Instruments is an automotive-qualified dual 3-state bus buffer gate operating from 1.65 V to 5.5 V, featuring ±24-mA output drive at 3.3 V, 4.3 ns max propagation delay, and Ioff support for partial-power-down mode - used in automotive infotainment data routing and body control module signal isolation.
For engineers reviewing the CLVC2G125IDCURQ1 datasheet, CLVC2G125IDCURQ1 pinout, CLVC2G125IDCURQ1 application, or CLVC2G125IDCURQ1 equivalent, key selection criteria include 3.3-V/5-V mixed-voltage interface compatibility, latch-up immunity (>100 mA per JESD 78 Class II), and VSSOP-8 package suitability for space-constrained automotive PCB layouts.
Technical Context
This device implements two independent noninverting buffers, each with active-low 3-state enable (OE) control logic. Output drivers are designed for rail-to-rail swing and tolerate input voltages up to 5.5 V regardless of VCC level, enabling robust level translation between 1.8-V, 2.5-V, 3.3-V, and 5-V domains.
The Ioff circuitry actively disables outputs during power-down, blocking reverse current flow when VCC = 0 V while inputs remain biased. Absolute maximum ratings include 6.5-V tolerance on all pins and thermal impedance of 227°C/W in the DCU package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports single-supply operation across legacy and modern automotive voltage rails. |
| tpd (Max) | 4.3 ns at VCC = 3.3 V - enables high-speed data buffering in CAN/LIN subsystem interconnects. |
| Ioff Current | ±10 μA max - prevents backflow damage during hot-insertion or staggered power sequencing. |
| Output Drive | ±24 mA at VCC = 3.3 V - drives standard 50-Ω transmission lines or multiple CMOS loads without external buffering. |
| Input Voltage Range | –0.5 V to 5.5 V - allows interfacing with 5-V logic even when powered from 1.8-V or 2.5-V supplies. |
| Latch-Up Immunity | >100 mA per JESD 78 Class II - meets AEC-Q100 stress requirements for under-hood electronics. |
| Operating Temp | –40°C to +85°C - qualified for passenger compartment and engine bay–adjacent modules. |
Pinout & Package
VSSOP-8 (DCU) package: 2.0 mm × 1.25 mm footprint, 0.5-mm lead pitch, 0.9-mm max height, RoHS-compliant NIPDAU finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low enable for Buffer 1 - pull high via resistor to ensure 3-state during power-up. |
| 2 | 1A | Noninverting input for Buffer 1 - accepts 5.5-V-tolerant logic signals independent of VCC. |
| 3 | 2Y | Inverting output of Buffer 2 - mislabeled in diagram; confirmed as noninverting output per logic diagram and function table. |
| 4 | GND | Digital ground reference - must be low-impedance connection to minimize ground bounce (VOLP < 0.8 V). |
| 5 | VCC | Supply voltage input - decoupling capacitor required within 1 cm to suppress switching noise. |
| 6 | 2OE | Active-low enable for Buffer 2 - independently controllable for selective bus gating. |
| 7 | 1Y | Noninverting output of Buffer 1 - provides rail-to-rail CMOS-compatible output swing. |
| 8 | 2A | Noninverting input for Buffer 2 - electrically identical to Pin 2, supporting dual-channel signal conditioning. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive Qualification | AEC-Q100 Grade 2 qualified - validated for use in safety-critical vehicle systems including ADAS sensor hubs. |
| Ioff Partial-Power-Down | Blocks reverse current when VCC = 0 V - eliminates need for external isolation switches in multi-rail power architectures. |
| 5.5-V-Tolerant Inputs | Accepts 5-V logic levels while powered from 1.65–2.5 V - simplifies migration from legacy 5-V microcontrollers. |
| Low Ground Bounce | VOLP < 0.8 V at VCC = 3.3 V - reduces EMI and timing uncertainty in high-density routing environments. |
| High-Speed Enable Control | ten = 4.7 ns (max) at VCC = 3.3 V - supports dynamic bus arbitration with sub-5-ns latency. |
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 |
|---|---|---|---|
| SN74LVC2G125DRYR | Industrial-grade (–40°C to 85°C), same electrical specs, X2SON-8 package (1.0 mm × 1.0 mm). | Lacks AEC-Q100 qualification; unsuitable for production automotive ECUs. | Select only for prototyping or non-automotive industrial use where footprint reduction is critical. |
| NC7WZ125P6X | Single-supply 1.65–5.5 V, but rated only to 85°C ambient, no Ioff, higher ICC (30 μA max). | Not qualified for automotive; lacks latch-up immunity >100 mA per JESD 78 Class II. | Use only in cost-sensitive consumer applications where AEC-Q100 compliance is not required. |
Compared with SN74LVC2G125DRYR and NC7WZ125P6X, the CLVC2G125IDCURQ1 uniquely combines AEC-Q100 Grade 2 qualification, Ioff-enabled partial-power-down, and VSSOP-8 manufacturability - making it the sole option for volume automotive designs requiring both reliability and board-space efficiency.

FAQ
What is the maximum operating voltage for CLVC2G125IDCURQ1?
The CLVC2G125IDCURQ1 supports a supply voltage range of 1.65 V to 5.5 V. Its absolute maximum rating is 6.5 V on VCC and all I/O pins, but sustained operation above 5.5 V violates recommended conditions and risks permanent damage. Operation at 5 V is fully characterized with 32-mA output drive and 3.7-ns tpd.
Does CLVC2G125IDCURQ1 support level translation between different logic families?
Yes, the CLVC2G125IDCURQ1 supports bidirectional level translation due to its 5.5-V-tolerant inputs and rail-to-rail output swing. For example, it can translate 5-V TTL signals to a 1.8-V MCU while powered from 1.8 V, provided the output load does not exceed ±24 mA at that VCC level.
How is the Ioff feature implemented in CLVC2G125IDCURQ1?
The CLVC2G125IDCURQ1 integrates dedicated Ioff circuitry that disables both output FETs when VCC = 0 V, limiting current flow to ±10 μA maximum even if inputs or outputs are biased to 5.5 V. This prevents backfeed into unpowered sections of the system, satisfying AEC-Q100 partial-power-down requirements.
What is the thermal resistance (θJA) of the CLVC2G125IDCURQ1 in its VSSOP-8 package?
The CLVC2G125IDCURQ1 in the DCU (VSSOP-8) package has a junction-to-ambient thermal resistance (θJA) of 227°C/W under JEDEC-standard conditions. This value assumes a 1-in² 2-oz copper pad with two vias; actual board layout significantly impacts real-world thermal performance.
Can CLVC2G125IDCURQ1 be used in place of SN74LVC2G125DRYR in an automotive design?
No - while CLVC2G125IDCURQ1 and SN74LVC2G125DRYR share identical logic functionality and electrical specs, only CLVC2G125IDCURQ1 carries AEC-Q100 Grade 2 qualification, automotive-grade process controls, and lot-level traceability required for production automotive ECUs. Substitution invalidates qualification.
