Product details
Overview
SN74LVC1G07DCK3 from Texas Instruments is a single non-inverting buffer/driver with open-drain output, designed for 1.65V–5.5V VCC operation. It delivers 32mA sink current at 4.5V, supports 5.5V-tolerant inputs/outputs, and achieves 4.2ns max propagation delay at 3.3V - enabling wired-OR logic, level translation, and LED driving in space-constrained consumer electronics.
For engineers reviewing the SN74LVC1G07DCK3 datasheet, SN74LVC1G07DCK3 pinout, SN74LVC1G07DCK3 application, or SN74LVC1G07DCK3 equivalent, key selection criteria include open-drain output drive capability (32mA), Ioff support for live insertion, ±24mA output drive at 3.3V, 0.5mm-pitch SC70-5 package compatibility, and operation across –40°C to +125°C.
Technical Context
The SN74LVC1G07DCK3 implements a CMOS-based single-channel non-inverting buffer with true open-drain output architecture - requiring an external pull-up resistor to define high-level voltage and enable active-low wired-OR or active-high wired-AND bus configurations. Its Ioff circuitry actively disables outputs when VCC = 0V, preventing back-drive current and supporting partial-power-down systems.
It operates across 1.65V–5.5V supply range while maintaining 5.5V input/output tolerance - enabling bidirectional voltage translation between disparate logic domains (e.g., 1.8V MCU GPIO to 3.3V or 5V peripheral bus). Input transition rate is specified down to 5 ns/V at 5V, ensuring robust timing margin in high-speed digital interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables interoperability across 1.8V, 2.5V, 3.3V, and 5V logic families without level-shifter ICs. |
| Max Sink Current (IOL) | 32mA at VCC = 4.5V - sufficient to directly drive LEDs, relays, or multiple CMOS inputs in wired-OR configurations. |
| tpd (max) | 4.2ns at VCC = 3.3V, TA = –40°C to +85°C - supports signal integrity in sub-100MHz digital control paths. |
| Ioff | <±10µA at VCC = 0V - guarantees isolation during hot-swap or power sequencing, protecting upstream logic from back-current. |
| Input Voltage Tolerance | Up to 5.5V independent of VCC - allows safe interfacing with higher-voltage signals even when powered at 1.65V. |
| ESD Rating (HBM) | 2000V - meets industrial-grade robustness requirements for handling and board assembly without special ESD controls. |
Pinout & Package
SN74LVC1G07DCK3 uses the SC70-5 (DCK) package: 2.0mm × 2.1mm body size, 0.65mm height, 0.5mm lead pitch, and 5-terminal configuration with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output sink path; must be low-impedance connection to system ground plane. |
| 2 | A | CMOS-compatible digital input; accepts 0V–5.5V regardless of VCC; no internal pull-up/down. |
| 3 | N.C. | No internal connection - electrically isolated; may be left floating or tied to GND for mechanical stability. |
| 4 | Y | Open-drain output; requires external pull-up resistor to define logic HIGH voltage; sinks up to 32mA. |
| 5 | VCC | Positive supply rail; powers internal logic and defines output LOW threshold; bypass capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Open-drain output | Enables wired-OR logic, I²C-style bus sharing, and flexible voltage-level translation via external pull-up selection. |
| Ioff partial-power-down | Prevents damaging current flow during hot insertion or mixed-rail power sequencing - critical for modular systems and field-replaceable units. |
| 5.5V input tolerance | Allows direct connection to legacy 5V peripherals or sensors without external clamping or resistive dividers. |
| Ultra-low ICC (10µA max) | Reduces quiescent power in always-on subsystems such as battery-backed status indicators or wake-on-event circuits. |
| SC70-5 footprint | 2.0mm × 2.1mm body enables high-density routing in portable audio, wearables, and compact SSD controller boards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DCKR | Same SC70-5 package, identical electrical specs, active production status vs. DCK3's obsolete status; RoHS-compliant NIPDAU/SN finish. | Direct replacement with guaranteed long-term availability and full TI support; compatible with same PCB layout and thermal design. | Select DCKR for new designs requiring assured supply continuity and full documentation access. |
| 74LVC1G07GW,125 | NXP variant in SOT353 (same SC70-5 footprint); matches VCC range, 32mA sink, and Ioff, but specifies only 1000V CDM ESD rating vs. TI's 1000V. | Valid for cost-sensitive consumer applications where full JESD22-A114-A (2000V HBM) compliance is not mandated. | Use GW,125 where second-source qualification is required and HBM margin is secondary to procurement flexibility. |
Compared with SN74LVC1G07DCK3, SN74LVC1G07DCKR offers guaranteed production continuity and full TI technical support, while 74LVC1G07GW,125 provides footprint-compatible second sourcing with slightly lower ESD robustness - both avoid redesign but differ in lifecycle assurance and qualification scope.

FAQ
What is the maximum sink current capability of the SN74LVC1G07DCK3?
The SN74LVC1G07DCK3 supports a maximum sink current of 32mA when VCC = 4.5V, as specified in the Absolute Maximum Ratings table. At 3.3V, it delivers ±24mA output drive. This makes SN74LVC1G07DCK3 suitable for driving LEDs, relays, or multiple CMOS loads without external amplification - provided the external pull-up resistor and thermal design accommodate the resulting power dissipation.
Does SN74LVC1G07DCK3 support level translation between different supply voltages?
Yes, SN74LVC1G07DCK3 supports bidirectional level translation due to its 5.5V-tolerant inputs and open-drain output. When powered at 1.8V, it can accept 3.3V or 5V input signals, and its output can be pulled up to any voltage ≤5.5V - enabling seamless interfacing between 1.65V–5.5V logic domains without additional components.
Is SN74LVC1G07DCK3 pin-compatible with other packages in the SN74LVC1G07 family?
No - SN74LVC1G07DCK3 uses the SC70-5 (DCK) package with specific pin 1–5 assignment (GND, A, N.C., Y, VCC). While functionally identical to DBV (SOT-23) and DPW (X2SON) variants, pinout differs: DBV places VCC at pin 5 but swaps N.C. and Y positions, and DPW has distinct top-view orientation. PCB layout must match DCK mechanical drawing.
What is the operating temperature range for SN74LVC1G07DCK3?
SN74LVC1G07DCK3 is rated for operation from –40°C to +125°C ambient temperature, consistent with its SC70-5 packaging and TI's industrial-grade qualification. This range applies to all electrical specifications including tpd, IOL, and Ioff, making SN74LVC1G07DCK3 suitable for under-hood automotive modules, industrial controllers, and high-temperature SSD environments.
How does the Ioff feature of SN74LVC1G07DCK3 protect system integrity?
The Ioff circuitry in SN74LVC1G07DCK3 disables output drivers when VCC = 0V, limiting leakage current to ±10µA. This prevents back-driving of unpowered sections during hot-swap events or partial power-down - preserving signal integrity, avoiding latch-up, and meeting JEDEC JESD78 Class II latch-up immunity (>100mA). SN74LVC1G07DCK3 thus enables robust modular system architectures.
