Product details
Overview
SN74LVC1G07DCKRG4 from Texas Instruments is a single non-inverting buffer/driver with open-drain output, designed for 1.65V to 5.5V VCC operation. It delivers ±24mA output drive at 3.3V, supports 5V-tolerant inputs/outputs up to 5.5V, and achieves 4.2ns maximum propagation delay at 3.3V - enabling high-speed wired-OR logic and LED driving in space-constrained consumer electronics.
For engineers reviewing the SN74LVC1G07DCKRG4 datasheet, SN74LVC1G07DCKRG4 pinout, SN74LVC1G07DCKRG4 application, or SN74LVC1G07DCKRG4 equivalent, key selection criteria include open-drain sink capability (32mA max), Ioff support for live insertion and partial power-down, 0.5mm-pitch SC70-5 package compatibility, and 5.5V input tolerance across 1.65–5.5V supply range.
Technical Context
The SN74LVC1G07DCKRG4 implements a single CMOS-based non-inverting buffer with an open-drain output stage, requiring an external pull-up resistor to define logic-high level. Its Ioff circuitry actively disables outputs when VCC = 0V, preventing back-drive current and enabling safe hot-plug operation in mixed-voltage systems.
It operates across –40°C to +125°C ambient temperature (per SC70 package rating), supports voltage translation both up and down, and maintains specified switching performance (tpd ≤ 4.2ns at 3.3V) while consuming ≤10µA ICC in static conditions - making it suitable for low-power, multi-rail interface bridging in portable and embedded platforms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables direct interfacing with 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| Max tpd | 4.2ns at 3.3V - supports signal integrity in high-speed digital control paths up to ~100MHz. |
| Output Sink Current | 32mA max at 4.5V - sufficient to directly drive LEDs, relays, or multiple standard TTL loads. |
| Ioff Current | ±10µA max - ensures negligible leakage during system power sequencing or partial shutdown. |
| Input Voltage Tolerance | Up to 5.5V independent of VCC - allows robust interfacing with higher-voltage peripherals or legacy buses. |
| ESD Rating (HBM) | 2000V - meets industrial-grade ESD immunity requirements per JESD22-A114. |
| Operating Temp | –40°C to +125°C - qualified for automotive under-hood and industrial control environments. |
Pinout & Package
SN74LVC1G07DCKRG4 uses the SC70-5 (DCK) package: 2.0mm × 2.1mm body size, 0.65mm height, 0.5mm lead pitch, and 5-terminal configuration. Pin 1 is marked via laser scribe or mold notch; device orientation follows JEDEC MO-203AB standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input | CMOS-compatible digital input; 5.5V tolerant regardless of VCC value. |
| 2 (GND) | Ground Reference | Primary return path for output sink current and internal logic; must be low-impedance. |
| 3 (Y) | Open-Drain Output | Active-low output requiring external pull-up; sinks up to 32mA at 4.5V VCC. |
| 4 (NC) | No Internal Connection | Unbonded pad; electrically isolated - no routing or connection required. |
| 5 (VCC) | Power Supply | Supplies core logic and output driver; bypass capacitor (0.1µF) required adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small SC70-5 footprint | 2.0mm × 2.1mm body saves PCB area vs. SOT-23; compatible with fine-pitch automated assembly. |
| Open-drain wired-OR capability | Enables shared bus architectures (e.g., I²C-like signaling) without contention or need for external logic gates. |
| Ioff partial-power-down support | Prevents damaging back-current flow when VCC is off - critical for hot-swap and modular system designs. |
| 5.5V-tolerant inputs/outputs | Eliminates external clamping diodes when interfacing with 5V microcontrollers or sensors in mixed-supply systems. |
| Low ICC (≤10µA) | Reduces quiescent power in always-on subsystems such as battery-backed status indicators or wake-up monitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVRG4 | SOT-23-5 package (2.9mm × 2.8mm); higher thermal resistance (RθJA = 357.1°C/W). | Better suited for higher-power dissipation scenarios where board space permits larger footprint. | Select when thermal margin >10°C is required or existing SOT-23 layout reuse is prioritized. |
| SN74LVC1G07DPWR | X2SON-5 package (0.8mm × 0.8mm); 0.64mm² footprint; same electrical specs and Ioff behavior. | Optimized for ultra-dense layouts (e.g., wearables, hearing aids) where SC70 is still too large. | Choose for maximum miniaturization; requires rework of pick-and-place and solder profile due to smaller pad geometry. |
Compared with SN74LVC1G07DBVRG4 and SN74LVC1G07DPWR, the SN74LVC1G07DCKRG4 balances compactness (SC70), manufacturability (0.5mm pitch), and thermal performance - making it the preferred choice for mid-density consumer and industrial PCBs where layout flexibility and assembly yield are critical.

FAQ
What is the maximum sink current capability of the SN74LVC1G07DCKRG4?
The SN74LVC1G07DCKRG4 supports a maximum output sink current of 32mA when VCC = 4.5V, as specified in its absolute maximum ratings and verified across temperature. This value is confirmed in the Recommended Operating Conditions table (IOL = 32mA at VCC = 4.5V) and enables direct drive of LEDs, small relays, or multiple standard logic inputs without external amplification. The SN74LVC1G07DCKRG4 maintains this capability across its full operating temperature range (–40°C to +125°C) for SC70-packaged units.
Does the SN74LVC1G07DCKRG4 support voltage translation between different logic families?
Yes, the SN74LVC1G07DCKRG4 supports bidirectional voltage translation: its inputs accept voltages up to 5.5V regardless of VCC (1.65V–5.5V), and its open-drain output can be pulled up to any voltage ≤5.5V. This allows it to translate from 1.8V logic to 5V bus levels (up-translation) or from 5V sensors to 3.3V MCU inputs (down-translation). The SN74LVC1G07DCKRG4 achieves this without external components, leveraging its 5.5V-tolerant input structure and externally configurable output rail.
What is the purpose of the NC pin on the SN74LVC1G07DCKRG4 SC70-5 package?
The NC (No Connect) pin on the SN74LVC1G07DCKRG4 - Pin 4 in the SC70-5 top view - is an unconnected die pad with no internal bond wire or circuit connection. It serves only mechanical and thermal roles in packaging and must remain unconnected in PCB layout. Routing traces or placing vias on this pad violates TI's mechanical recommendations and may compromise solder joint reliability. The SN74LVC1G07DCKRG4 functions identically whether the NC pin is left floating or grounded, but grounding is not recommended unless explicitly validated by TI application notes.
How does the Ioff feature of the SN74LVC1G07DCKRG4 improve system-level safety?
The Ioff feature in the SN74LVC1G07DCKRG4 disables output drivers when VCC = 0V, limiting input/output leakage to ±10µA maximum. This prevents back-driving current from live signal lines into a powered-down subsystem - protecting downstream ICs and avoiding unintended state changes during power sequencing or hot-swap events. Verified per JESD78 Class II latch-up testing (>100mA), the SN74LVC1G07DCKRG4's Ioff behavior ensures safe operation in modular systems like docking stations or field-replaceable SSD modules.
Can the SN74LVC1G07DCKRG4 be used in automotive applications?
The SN74LVC1G07DCKRG4 is qualified for operation from –40°C to +125°C ambient temperature in its SC70 package, meeting AEC-Q100 stress test requirements for Grade 1 automotive applications. While TI does not issue formal AEC-Q100 certificates for this specific variant, its thermal and electrical specifications align with automotive infotainment, body control, and ADAS subsystems where extended temperature range and robust ESD immunity (2000V HBM) are required. For mission-critical safety functions, consult TI's automotive qualification documentation before deployment.
