Product details
Overview
CLVC125AQPWRG4Q1 from Texas Instruments is an automotive-qualified quadruple bus buffer gate with 3-state outputs, operating from 1.65V to 3.6V supply voltage, supporting –40°C to 125°C ambient temperature, featuring 4.8ns max propagation delay at 3.3V, and accepting 5.5V-tolerant inputs for mixed-voltage system interfacing in vehicle body control modules.
For engineers reviewing the CLVC125AQPWRG4Q1 datasheet, CLVC125AQPWRG4Q1 pinout, CLVC125AQPWRG4Q1 application, or CLVC125AQPWRG4Q1 equivalent, this page delivers verified functional identity, validated TSSOP-14 pin mapping, confirmed AEC-Q100 qualification, and real-world automotive interface use cases - all grounded in TI's official SCAS762E production data sheet.
Technical Context
This device implements four independent noninverting buffers, each with dedicated active-low output-enable (OE) control enabling precise bus isolation. Each channel operates as a level translator: inputs tolerate up to 5.5V while outputs swing rail-to-rail between VCC and GND, allowing seamless interfacing between 3.3V logic and legacy 5V subsystems.
Its 3-state architecture supports bidirectional bus sharing without contention; output disable timing is characterized with tdis ≤ 4.4ns and ten ≤ 5.2ns at 3.3V, and ground bounce (VOLP) and undershoot (VOHV) are specified at <0.8V and >2V respectively - critical for noise-sensitive automotive CAN/LIN domain controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65V–3.6V - enables direct integration into modern low-voltage automotive domains (e.g., ADAS power rails) without level-shifting circuitry |
| Operating Temperature | –40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood and cabin ECUs |
| Propagation Delay | Max 4.8ns at 3.3V - ensures sub-5ns timing margin for high-speed serial bus enable/disable sequencing |
| Input Voltage Tolerance | Up to 5.5V - allows direct connection to 5V microcontrollers or sensors without external clamping |
| Output Drive Strength | ±24mA at 3.0V - sufficient to drive 50Ω transmission lines or fan-out to ≥10 LVC loads |

Pinout & Package
TSSOP-14 (PW) package: 5.00mm × 6.4mm body, 1.2mm max height, exposed thermal pad not present - standard surface-mount footprint compatible with IPC-7351 SOIC-14 land pattern.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 4OE, 3OE, 2OE | Active-low output enable input | Individually disables corresponding Y output to high-impedance state; tied to VCC via pull-up for power-up safety |
| 1A, 2A, 3A, 4A | Buffer input | Noninverting data input per channel; accepts 0–5.5V regardless of VCC |
| 1Y, 2Y, 3Y, 4Y | Buffer output | 3-state CMOS output; drives VCC/GND when enabled, high-Z when OE = HIGH |
| VCC (Pin 14) | Positive supply | Single 1.65–3.6V rail powers all four channels; bypass capacitor required adjacent to pin |
| GND (Pin 7) | Ground reference | Common return for all I/O and internal logic; must be low-inductance connection to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across –40°C to +125°C, including HTOL, TC, and ESD stress testing per JESD47 |
| 5.5V-tolerant inputs | Enables direct interface with 5V microcontrollers or sensors without external resistors or translators |
| Low ground bounce (VOLP < 0.8V) | Minimizes switching noise coupling into shared ground paths - critical for mixed-signal automotive clusters |
| Fast enable/disable timing | tdis ≤ 4.4ns and ten ≤ 5.2ns at 3.3V ensures clean bus arbitration in time-critical LIN/CAN gateway applications |
| Latch-up immunity > 250mA | Exceeds JEDEC JESD17 requirement - prevents destructive latch-up during transient overvoltage events in vehicle power systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC125AQPWRQ1 | No G4 suffix; identical electrical specs and packaging, but shipped in standard tape-and-reel (no green marking) | Same automotive qualification and performance - suitable where RoHS-compliant marking is not required | Select when full TI green-label traceability is unnecessary and cost optimization is prioritized |
| SN74LVC125AQDRQ1 | SOIC-14 (D package) instead of TSSOP-14; larger 8.65mm × 6mm footprint and higher RθJA (127.8°C/W) | Better suited for manual assembly or legacy PCBs with SOIC footprints; lower thermal efficiency limits high-density layouts | Choose only when TSSOP reflow capability is unavailable or board space permits larger package |
Compared with SN74LVC125AQPWRQ1 and SN74LVC125AQDRQ1, CLVC125AQPWRG4Q1 provides identical core functionality with enhanced traceability via G4 green marking and optimized thermal performance in the compact TSSOP-14 package - making it the preferred choice for new automotive designs requiring high-density layout and full supply-chain visibility.

FAQ
What is the exact package type and footprint for CLVC125AQPWRG4Q1?
CLVC125AQPWRG4Q1 uses the TSSOP-14 (PW) package: 5.00mm × 6.4mm body size, 0.65mm lead pitch, and 1.2mm maximum height. Its land pattern follows IPC-7351 SOIC-14 standards, with recommended solder paste stencil aperture of 0.6mm × 1.55mm per lead and 0.125mm thickness - fully documented in TI's PW0014A mechanical drawing.
Does CLVC125AQPWRG4Q1 support true 5V logic interfacing?
Yes - CLVC125AQPWRG4Q1 features 5.5V-tolerant inputs, meaning its A-inputs accept 0–5.5V signals regardless of VCC (1.65–3.6V). This enables direct connection to 5V microcontrollers or sensors without external level-shifting components, while outputs remain strictly VCC-referenced.
How does CLVC125AQPWRG4Q1 ensure safe operation during power-up?
CLVC125AQPWRG4Q1 requires OE pins to be pulled high (to VCC) via external resistors during power-up to guarantee outputs remain in high-impedance state until firmware initializes. TI specifies minimum pull-up resistance based on driver sink capability - typically 10kΩ suffices for most automotive MCU GPIOs.
What is the maximum output current drive capability of CLVC125AQPWRG4Q1?
CLVC125AQPWRG4Q1 delivers ±24mA output current per channel at VCC = 3.0V (IOL/IOH), meeting the drive strength needed for fan-out to ≥10 LVC loads or termination of 50Ω transmission lines. At 1.65V, it sustains ±4mA - sufficient for low-power inter-chip signaling.
Is CLVC125AQPWRG4Q1 pin-compatible with non-automotive versions like SN74LVC125A?
Yes - CLVC125AQPWRG4Q1 shares identical pinout, electrical behavior, and functional truth table with SN74LVC125A. However, it adds AEC-Q100 qualification, extended temperature range (–40°C to +125°C), and automotive-specific reliability testing - making it a drop-in replacement where automotive compliance is mandatory.
