Product details
Overview
CLVC1G125QDBVRQ1 from Texas Instruments is an automotive-qualified single 3-state bus buffer gate (Y = A) operating from 1.65V to 5.5V VCC, delivering ±24mA output drive at 3.3V, with 3.7ns max propagation delay and 5.5V-tolerant inputs - used for signal redriving, digital enable/disable control, and LED driving in automotive infotainment and body control modules.
For engineers reviewing the CLVC1G125QDBVRQ1 datasheet, CLVC1G125QDBVRQ1 pinout, CLVC1G125QDBVRQ1 application, or CLVC1G125QDBVRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, Ioff partial-power-down support, SOT-23-5 package footprint, and 100MHz square-wave redrive capability under 125°C ambient conditions.
Technical Context
This CMOS buffer implements a noninverting logic function with active-low 3-state output enable (OE), where Y = A when OE is low and Y = high-impedance when OE is high. Its Ioff circuitry blocks current flow when VCC = 0V, enabling live insertion and back-drive protection in hot-swap systems.
The device supports voltage translation: inputs tolerate up to 5.5V regardless of VCC (1.65–5.5V), allowing interfacing between higher-voltage logic and lower-VCC domains while maintaining rail-to-rail output swing. Thermal resistance is RθJA = 357.1°C/W in the DBV package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables interoperability across 1.8V, 2.5V, 3.3V, and 5V logic families |
| Max Propagation Delay | 3.7ns at 3.3V - supports clean 100MHz square-wave redriving without edge degradation |
| Output Drive | ±24mA at 3.3V - sufficient to drive multiple CMOS loads or LEDs directly without external buffers |
| Input Voltage Tolerance | Up to 5.5V - allows connection to 5V buses while powered from 3.3V or lower supplies |
| Ioff Current | <±10μA at VCC = 0V - prevents damaging back-current during partial power-down or hot-plug events |
| Operating Temperature | –40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood automotive applications |
| ESD Rating | ±2000V HBM - robust handling in manufacturing and field service environments |
Pinout & Package
SOT-23-5 (DBV) package: 2.90mm × 1.60mm body, 0.95mm height, gull-wing leads, RoHS-compliant NiPdAu/Sn lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OE | Active-low output enable input | Drives Y high-impedance when high; must be pulled up to VCC via resistor during power sequencing to maintain Z-state |
| 2 - A | Noninverting data input | Accepts 5.5V-tolerant signals; logic high ≥0.7×VCC (min), low ≤0.3×VCC (max) |
| 3 - GND | Ground reference | Primary return path for all internal currents; requires low-inductance connection to system ground plane |
| 4 - Y | 3-state buffered output | Delivers rail-to-rail CMOS output swing; sinks or sources up to ±24mA at 3.3V |
| 5 - VCC | Positive supply | Must be bypassed with 0.1μF ceramic capacitor placed within 2mm of pin; supports 1.65–5.5V operation |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to +125°C) - certified for safety-critical vehicle subsystems including ADAS sensors and gateway ECUs |
| Ioff partial-power-down | Enables safe hot-insertion and isolation when VCC is unpowered - critical for modular ECU architectures with staggered power rails |
| Voltage translation | 5.5V-tolerant inputs + down-translation to VCC - eliminates level-shifters when interfacing legacy 5V peripherals to modern 3.3V microcontrollers |
| Low static power | 10μA max ICC - reduces quiescent current in always-on vehicle networks (e.g., LIN, CAN standby nodes) |
| High-speed redriving | 3.7ns tpd at 3.3V - preserves signal integrity for clock distribution, SPI, and UART lines up to 100MHz |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DRYRQ1 | SON-6 package (1.45mm × 1.00mm); adds NC pin; RθJA = 439°C/W; same electrical specs | Better thermal performance in space-constrained layouts; requires different PCB footprint and stencil design | Select when board area is critical and thermal dissipation can be managed via bottom-side copper pour |

FAQ
What is the maximum operating frequency supported by the CLVC1G125QDBVRQ1?
The CLVC1G125QDBVRQ1 is characterized for reliable 100MHz square-wave redriving per the datasheet's Application section. Its 3.7ns max propagation delay at 3.3V ensures clean signal edges at this rate, though actual usable frequency depends on load capacitance, PCB routing, and termination - verified operation up to 100MHz is documented for CLVC1G125QDBVRQ1 in TI's official test reports.
Does the CLVC1G125QDBVRQ1 support partial power-down functionality?
Yes, the CLVC1G125QDBVRQ1 includes Ioff circuitry that disables both input and output ports when VCC = 0V, limiting leakage to ±10μA. This feature enables safe live insertion and prevents back-current damage in modular automotive ECUs - a core requirement validated under AEC-Q100 stress testing for CLVC1G125QDBVRQ1.
What is the recommended pull-up resistor value for the OE pin on CLVC1G125QDBVRQ1?
Texas Instruments recommends tying OE to VCC via a pull-up resistor to maintain high-impedance output during power-up/down transients. The minimum value is determined by the driver's sink capability; for standard 3.3V operation, a 10kΩ resistor is typical and sufficient - confirmed in the CLVC1G125QDBVRQ1 Functional Modes section and Layout Guidelines.
Can CLVC1G125QDBVRQ1 interface between a 5V microcontroller and a 3.3V FPGA?
Yes, CLVC1G125QDBVRQ1 accepts 5.5V-tolerant inputs while powered from 3.3V, enabling direct connection of 5V MCU outputs to its A pin. Its output swings rail-to-rail (0V to 3.3V), making it ideal for level-shifting into 3.3V FPGA I/O banks - this use case is explicitly validated in the CLVC1G125QDBVRQ1 Applications and Feature Description sections.
Is CLVC1G125QDBVRQ1 pin-compatible with non-automotive versions like SN74LVC1G125?
Yes, CLVC1G125QDBVRQ1 uses the same SOT-23-5 (DBV) package and identical pinout as SN74LVC1G125, with matching A, OE, GND, Y, and VCC assignments. However, CLVC1G125QDBVRQ1 adds AEC-Q100 qualification, enhanced ESD ratings (±2000V HBM), and extended temperature validation - electrical behavior is otherwise identical.
