Product details
Overview
SN74LVC1G07QDBVRQ1 from Texas Instruments is an automotive-grade single-channel open-drain buffer/driver, designed for 1.65 V to 5.5 V operation, delivering 32 mA sink current at 4.5 V, with 5.7 ns max propagation delay at 3.3 V and ±24 mA output drive capability - used in wired-OR logic, LED driving, and level translation in ADAS camera interfaces.
For engineers reviewing the SN74LVC1G07QDBVRQ1 datasheet, SN74LVC1G07QDBVRQ1 pinout, SN74LVC1G07QDBVRQ1 application, or SN74LVC1G07QDBVRQ1 equivalent, key selection considerations include AEC-Q100 Grade 1 qualification (–40°C to +125°C), Ioff partial-power-down support, 5.5 V tolerant inputs, and SOT-23-5 package compatibility with space-constrained automotive PCB layouts.
Technical Context
This device implements a non-inverting open-drain buffer with no internal pull-up, requiring external termination for active-high logic. Its Ioff circuitry actively disables outputs when VCC = 0 V, blocking back-current flow during power sequencing - critical for mixed-voltage domain isolation in body control modules.
Input voltage tolerance up to 5.5 V enables down-translation from 5 V logic to 1.8 V/3.3 V domains, while the 32 mA sink capability supports direct LED driving and robust wired-AND bus interfacing without additional transistors. Propagation delay remains stable across temperature (±0.5 ns variation from –40°C to 125°C at 3.3 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families |

Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DRYRQ1 | Same silicon die, SON-6 (DRY) package - 1.45 mm × 1.00 mm, 0.5 mm pitch, no N.C. pin | Used where ultra-small footprint and improved thermal performance (RθJA = 439°C/W) are prioritized over SOT-23 reworkability | Select SN74LVC1G07DRYRQ1 only if board space is constrained and automated assembly supports 0.5 mm pitch. |
| SN74LVC1G07DCKRQ1 | Same functionality, SC70-5 (DCK) package - 2.00 mm × 2.10 mm, MSL Level-2, Sn finish | Preferred for cost-sensitive consumer-tier automotive accessories where RoHS-compliant Sn finish and smaller footprint than SOT-23 are needed | Choose SN74LVC1G07DCKRQ1 when balancing size, reflow profile constraints, and procurement flexibility across TI's Q1 portfolio. |
Compared with SN74LVC1G07QDBVRQ1, the DRY variant offers 30% smaller area but requires tighter placement accuracy, while the DCK version trades slightly higher thermal resistance (371°C/W vs. 357°C/W) for broader distributor availability and lower assembly cost - both retain identical electrical specs and AEC-Q100 Grade 1 qualification.

FAQ
What is the maximum sink current specification for SN74LVC1G07QDBVRQ1?
The SN74LVC1G07QDBVRQ1 supports a maximum sink current of 32 mA at VCC = 4.5 V, as specified in the Recommended Operating Conditions table. This value is validated across the full –40°C to +125°C temperature range and enables direct LED driving or termination of high-speed buses without external components. The device maintains this rating under continuous DC conditions with proper thermal management.
Does SN74LVC1G07QDBVRQ1 support partial-power-down operation?
Yes, SN74LVC1G07QDBVRQ1 includes Ioff circuitry that disables outputs when VCC = 0 V, limiting Ioff leakage to ±10 μA at 5.5 V. This feature prevents damaging back-current flow during power sequencing in systems with mixed-voltage domains - essential for automotive body control modules where subsystems power up/down independently.
What is the propagation delay of SN74LVC1G07QDBVRQ1 at 3.3 V?
The maximum propagation delay (tpd) of SN74LVC1G07QDBVRQ1 is 5.7 ns at VCC = 3.3 V, measured under standard load conditions (CL = 50 pF). Typical tpd is 1.5 ns at the same voltage, providing timing margin for 100 MHz digital interfaces. Delay remains stable across temperature, varying less than ±0.5 ns from –40°C to +125°C.
Can SN74LVC1G07QDBVRQ1 interface with 5 V logic while operating at 1.8 V VCC?
Yes, SN74LVC1G07QDBVRQ1 accepts input voltages up to 5.5 V regardless of VCC setting, enabling reliable down-translation from 5 V controllers to 1.8 V or 3.3 V domains. Inputs remain fully functional at VI = 5.5 V even when VCC = 1.65 V, eliminating the need for external level-shifting components in mixed-voltage automotive subsystems.
Is SN74LVC1G07QDBVRQ1 qualified for automotive applications?
Yes, SN74LVC1G07QDBVRQ1 is AEC-Q100 qualified for automotive use with Device Temperature Grade 1 (–40°C to +125°C ambient), ±2000 V HBM and ±1000 V CDM ESD ratings, and full characterization across automotive voltage and thermal stress profiles - making it suitable for ADAS, infotainment, and powertrain applications.
