Product details
Overview
SN74LVC1G07QDCKRQ1 from Texas Instruments is an automotive-grade single-channel open-drain buffer/driver operating from 1.65 V to 5.5 V, 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. It serves as a level-translating interface or wired-OR logic element in automotive infotainment and ADAS camera systems.
For engineers reviewing the SN74LVC1G07QDCKRQ1 datasheet, SN74LVC1G07QDCKRQ1 pinout, SN74LVC1G07QDCKRQ1 application, or SN74LVC1G07QDCKRQ1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification (–40°C to +125°C), Ioff partial-power-down support, 5.5 V-tolerant inputs, and SC70-5 package compatibility for space-constrained automotive PCBs.
Technical Context
The SN74LVC1G07QDCKRQ1 implements a non-inverting open-drain buffer with no internal pull-up; external pull-up is required 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 automotive subsystems.
Input voltage tolerance up to 5.5 V enables down-translation from higher-voltage domains (e.g., 5 V microcontrollers) into 1.8 V or 3.3 V logic rails. The device supports wired-AND/wired-OR bus configurations via shared open-drain outputs, with guaranteed sink performance across its full 1.65–5.5 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports direct interfacing between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| Max Sink Current (IOL) | 32 mA at 4.5 V - sufficient to drive LEDs, relays, or multiple CMOS inputs without external amplification |
| tpd (max) | 5.7 ns at 3.3 V - enables reliable operation in high-speed digital control paths up to ~100 MHz |
| Ioff Current | ±10 μA - ensures safe isolation during hot-insertion or partial power-down of subsystems |
| Input Voltage Tolerance | 0 V to 5.5 V - allows 5 V signals to be safely applied regardless of VCC level, enabling robust level shifting |
| Ambient Temp Range | –40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood and cabin-mounted automotive electronics |
| ESD Rating (HBM) | ±2000 V - meets automotive ESD immunity requirements for infotainment and sensor interface modules |
Pinout & Package
SN74LVC1G07QDCKRQ1 uses the SC70-5 (DCK) package: 2.00 mm × 2.10 mm body, 1.25 mm width, 5-pin surface-mount outline with pin 1 in quadrant Q3 per tape-and-reel standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (N.C.) | No internal connection | Unused pad; must remain unconnected-no routing or soldering required |
| 2 (A) | Input | CMOS-compatible signal input accepting 0–5.5 V; drives internal buffer stage |
| 3 (GND) | Ground reference | Primary return path for sink current and internal logic; requires low-impedance PCB connection |
| 4 (Y) | Open-drain output | Active-low output requiring external pull-up; sinks up to 32 mA when driven low |
| 5 (VCC) | Power supply | Supplies internal logic; must be bypassed with 0.1 μF capacitor placed adjacent to pin |
Key Features

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 | SON-6 (DRY) package, 1.45 mm × 1.00 mm body, 6-pin layout with dedicated N.C. pin | Higher board density but requires re-layout; same electrical specs and AEC-Q100 Grade 1 rating | Select when footprint miniaturization outweighs assembly complexity and cost premium of 6-pin SON |
| SN74LVC1G07DBVRQ1 | SOT-23-5 (DBV) package, 2.90 mm × 1.60 mm body, larger footprint and thermal resistance (RθJA = 357.1°C/W) | Better thermal dissipation in high-ambient environments; compatible with legacy SOT-23 pick-and-place tooling | Select for thermal margin in under-hood applications or where SOT-23 placement infrastructure is already established |
Compared with SN74LVC1G07QDCKRQ1, the DRY variant offers superior space efficiency but adds a sixth pin and tighter assembly tolerances, while the DBV variant trades size for easier handling and lower thermal impedance-making SC70 optimal for compact, thermally managed cabin modules.

FAQ
What is the maximum sink current capability of the SN74LVC1G07QDCKRQ1 at 3.3 V?
The SN74LVC1G07QDCKRQ1 delivers up to 24 mA sink current at 3.3 V, as specified in the Recommended Operating Conditions table. This value is confirmed across temperature (–40°C to +125°C) and ensures reliable driving of LEDs, optocouplers, or multiple CMOS inputs without exceeding absolute maximum ratings. The device maintains this performance with VOL ≤ 0.4 V under load.
Does the SN74LVC1G07QDCKRQ1 support level translation between 5 V and 1.8 V logic domains?
Yes, the SN74LVC1G07QDCKRQ1 supports bidirectional level translation: its inputs tolerate up to 5.5 V regardless of VCC, and it operates down to 1.65 V. When VCC = 1.8 V, a 5 V input is safely accepted and translated to a 1.8 V-compatible open-drain output-enabling direct interface between legacy 5 V peripherals and modern low-voltage MCUs without external components.
Is the SN74LVC1G07QDCKRQ1 pin-compatible with other members of the SN74LVC1G07-Q1 family?
SN74LVC1G07QDCKRQ1 shares identical logic functionality and pin functions (A, Y, GND, VCC, N.C.) with SN74LVC1G07DBVRQ1 and SN74LVC1G07DRYRQ1, but the SC70-5 (DCK), SOT-23-5 (DBV), and SON-6 (DRY) packages differ in pin count, pitch, and footprint. Only DBV and DCK variants are 5-pin and functionally interchangeable with board-level redesign; DRY requires layout change due to its 6-pin configuration.
How does the Ioff feature of the SN74LVC1G07QDCKRQ1 protect system-level power sequencing?
The Ioff circuitry in the SN74LVC1G07QDCKRQ1 disables all outputs when VCC = 0 V, limiting Ioff current to ±10 μA. This prevents back-current flow from live signal lines (e.g., 5 V I²C bus) into a powered-down subsystem-ensuring safe hot-plug operation, preventing latch-up, and meeting automotive power-domain isolation requirements during ignition cycling or module sleep/wake transitions.
What is the recommended bypass capacitor for the VCC pin of the SN74LVC1G07QDCKRQ1?
A 0.1 μF ceramic capacitor is recommended for the VCC pin of the SN74LVC1G07QDCKRQ1, placed as close as possible to the pin with minimal trace length. This value is specified in TI's Power Supply Recommendations section and provides effective high-frequency noise suppression across the 1.65–5.5 V operating range. For systems with additional noise sources, paralleling with a 1 μF capacitor further improves low-frequency decoupling.
