Texas Instruments CLVC3G07QDCURG4Q1

Overview

CLVC3G07QDCURG4Q1 from Texas Instruments is an automotive-qualified triple buffer/driver IC with open-drain outputs, designed for 1.65-V to 5.5-V VCC operation. It provides three independent noninverting buffers, each capable of sinking up to 32 mA at 4.5 V, supports partial-power-down via Ioff, and delivers 3.7 ns max propagation delay at 3.3 V - used in automotive body control modules for level-shifting and wired-AND logic interfacing.

For engineers reviewing the CLVC3G07QDCURG4Q1 datasheet, CLVC3G07QDCURG4Q1 pinout, CLVC3G07QDCURG4Q1 application, or CLVC3G07QDCURG4Q1 equivalent, key selection criteria include open-drain sink capability (32 mA @ 4.5 V), Ioff-enabled power-down isolation, ±24-mA drive at 3.3 V, 3.7 ns tpd at 3.3 V, and AEC-Q100 Grade 1 qualification (–40°C to 125°C).

Technical Context

This device implements three identical noninverting buffer stages, each with an open-drain output stage enabling wired-OR/AND logic and voltage-level translation across domains. Its Ioff circuitry actively disables outputs during power-down, blocking reverse current flow when VCC = 0 V.

The input structure accepts voltages up to 5.5 V regardless of VCC (1.65–5.5 V), supporting mixed-voltage system interfacing. Output VOL remains ≤0.65 V at 32 mA sink and 125°C, ensuring reliable low-state signaling in hot under-hood environments.

FAQ

What is the maximum sink current specification for CLVC3G07QDCURG4Q1 at 125°C?

The CLVC3G07QDCURG4Q1 supports up to 32 mA sink current at 4.5 V VCC and 125°C ambient temperature, with a guaranteed VOL ≤ 0.65 V under those conditions. This rating is confirmed in the Electrical Characteristics table of the SCES616B datasheet and enables direct driving of automotive relays and LEDs without external amplification. The CLVC3G07QDCURG4Q1 maintains this performance across its full operating temperature range.

Does CLVC3G07QDCURG4Q1 support partial-power-down operation, and how does it behave when VCC = 0 V?

Yes, CLVC3G07QDCURG4Q1 supports partial-power-down via its Ioff circuitry. When VCC = 0 V, all outputs are placed in high-impedance state with leakage current limited to ±10 µA maximum, preventing damaging back-current flow from live inputs or outputs into the unpowered device. This behavior is explicitly verified per JESD 78 Class II latch-up testing and is critical for automotive modules with staggered power sequencing. The CLVC3G07QDCURG4Q1 remains safe and functional during such conditions.

Can CLVC3G07QDCURG4Q1 inputs safely interface with 5-V logic while operating at VCC = 1.8 V?

Yes, CLVC3G07QDCURG4Q1 inputs tolerate voltages up to 5.5 V regardless of VCC level, including when VCC = 1.8 V. This is specified in both Absolute Maximum Ratings and Recommended Operating Conditions tables. No external clamping or level-shifting components are required, simplifying interconnection between legacy 5-V sensors and modern low-voltage MCUs. The CLVC3G07QDCURG4Q1 leverages this feature to reduce system BOM cost and improve signal integrity.

What is the propagation delay (tpd) of CLVC3G07QDCURG4Q1 at 3.3 V, and how does it vary with temperature?

The CLVC3G07QDCURG4Q1 has a maximum propagation delay of 3.7 ns at VCC = 3.3 V and TA = 25°C, with typical values lower across voltage and temperature. The datasheet specifies tpd over the full –40°C to 125°C range, and worst-case delay remains within 3.7 ns at 3.3 V across that span. This consistent timing enables predictable synchronization in automotive timing-critical functions such as PWM-controlled lighting or window motor commutation. The CLVC3G07QDCURG4Q1 delivers this performance without derating.

Is CLVC3G07QDCURG4Q1 pin-compatible with SN74LVC3G07QDCURQ1, and what is the practical difference between them?

Yes, CLVC3G07QDCURG4Q1 is pin-compatible and functionally identical to SN74LVC3G07QDCURQ1 - same VSSOP-8 (DCU) package, identical pinout, identical electrical and thermal specifications, and shared AEC-Q100 qualification. The only difference is the top-side marking (C07R vs C07_) and the G4 suffix, which denotes TI's green packaging standard (lead-free, halogen-free). For design reuse, the CLVC3G07QDCURG4Q1 can replace SN74LVC3G07QDCURQ1 without layout or firmware changes.
