Product details
Overview
SN74LVC1G07DSFR 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 and level translation in space-constrained consumer audio and embedded interfaces.
For engineers reviewing the SN74LVC1G07DSFR datasheet, SN74LVC1G07DSFR pinout, SN74LVC1G07DSFR application, or SN74LVC1G07DSFR equivalent, key selection criteria include open-drain drive strength (32mA), Ioff support for live insertion, 0.5mm-pitch 1.0mm×1.0mm DSF package, and compatibility with 1.65V–5.5V mixed-voltage systems.
Technical Context
The SN74LVC1G07DSFR implements a single CMOS buffer with true open-drain output architecture, requiring an external pull-up to define high-state voltage and enable wired-OR/AND bus configurations. Its Ioff circuitry actively disables outputs when VCC = 0V, preventing back-drive current and supporting partial-power-down modes.
It operates across –40°C to 125°C ambient temperature (per DSF package rating), accepts input voltages up to 5.5V independent of VCC, and maintains specified switching performance (tpd ≤ 4.7ns at 3.3V, –40°C to 125°C) while consuming ≤10µA ICC in static operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| Max Sink Current (IOL) | 32mA at 4.5V - sufficient to directly drive LEDs, relays, or multiple CMOS inputs in wired-OR buses. |
| Propagation Delay (tpd) | 4.2ns max at 3.3V, –40°C to 85°C - supports signal integrity in sub-100MHz digital control paths. |
| Ioff | ±10µA max - ensures safe live insertion and prevents back-current flow during power sequencing or hot-swap events. |
| Input Voltage Tolerance | 0V to 5.5V - allows interfacing with higher-voltage controllers (e.g., 5V microcontrollers) while powered from lower VCC. |
| ESD Rating (HBM) | 2000V - meets industrial-grade robustness requirements per JESD22-A114. |
| Package | DSF (SON, 6-pin) - 1.0mm × 1.0mm body, 0.5mm pitch, exposed thermal pad for improved thermal dissipation. |
Pinout & Package
SN74LVC1G07DSFR uses the DSF (SON, 6-pin) package: 1.0mm × 1.0mm body size, 0.5mm pitch, with exposed thermal pad (pin 6). Pin 1 is marked by beveled corner; pin 6 is thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input | CMOS-compatible digital input; 5.5V tolerant regardless of VCC value. |
| 2 (GND) | Ground | Primary reference for all internal circuitry and output sink path. |
| 3 (N.C.) | No internal connection | Unbonded die pad; must be left floating or tied to GND for mechanical stability (no electrical function). |
| 4 (Y) | Open-drain output | Sinks current only; requires external pull-up to define logic HIGH voltage and implement wired-OR functionality. |
| 5 (VCC) | Power supply | Supplies core logic and output driver; range 1.65V–5.5V; bypass capacitor required. |
| 6 (Thermal pad) | Thermal interface | Non-electrical copper pad for PCB heat conduction; must be soldered to thermal plane for rated performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small DSF package | 1.0mm × 1.0mm footprint with 0.5mm pitch - reduces board area by >70% vs. SOT-23, ideal for portable media players and SSD modules. |
| Wide VCC range | 1.65V to 5.5V operation - eliminates need for separate level translators in mixed-voltage systems (e.g., 1.8V SoC driving 3.3V peripherals). |
| 5.5V-tolerant I/O | Inputs and open-drain output accept up to 5.5V regardless of VCC - enables direct connection to legacy 5V controllers without clamping diodes. |
| Ioff protection | Active output disable at VCC = 0V - prevents back-driving and latch-up during hot-plug or power sequencing in modular embedded systems. |
| High sink drive | 32mA maximum sink current at 4.5V - supports direct LED indication, relay coil driving, or fan-out to ≥10 standard CMOS loads. |
Applications
| LED Indicator Driver | Wired-OR Bus Interface |
|---|---|
|
Use Scenario: Driving status LEDs on portable media players and digital picture frames where board space and power efficiency are critical. IC Role / Device Role / Timing Role: Open-drain buffer sinking current from LED anode tied to system rail; provides logic-controlled illumination without external transistor.

Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVR | SOT-23-5 package (2.9mm × 1.6mm); 5-pin; no thermal pad; 32mA sink at 4.5V; same electrical specs. | Larger footprint; less thermal performance; suitable for cost-sensitive, non-space-constrained PCBs. | Select when board layout allows larger package and thermal management is not critical. |

FAQ
What is the maximum sink current specification for SN74LVC1G07DSFR?
The SN74LVC1G07DSFR supports a maximum sink current (IOL) of 32mA when VCC = 4.5V, as specified in the Electrical Characteristics table under Recommended Operating Conditions. This rating applies across the full operating temperature range (–40°C to 125°C) and enables direct driving of LEDs, small relays, or wired-OR bus loads without external amplification.
Does SN74LVC1G07DSFR support level translation between different voltage domains?
Yes, SN74LVC1G07DSFR supports both up-translation and down-translation. Its 5.5V-tolerant inputs accept signals up to 5.5V regardless of VCC, and its open-drain output can be pulled up to any voltage ≤5.5V - allowing it to translate a 1.8V logic signal to a 3.3V or 5V bus, or vice versa, using appropriate external pull-up resistors.
What is the purpose of the thermal pad (pin 6) on the SN74LVC1G07DSFR DSF package?
The thermal pad (pin 6) on SN74LVC1G07DSFR is a non-electrical copper land designed for soldering to a PCB thermal plane. It significantly improves heat dissipation - reducing junction-to-board thermal resistance (RθJB = 271°C/W) - which is essential when operating near maximum sink current (e.g., 24–32mA) in compact, thermally constrained environments like SSD modules or portable media players.
Can SN74LVC1G07DSFR be used in partial-power-down systems?
Yes, SN74LVC1G07DSFR includes Ioff circuitry that disables outputs when VCC = 0V, limiting Ioff to ±10µA. This feature prevents damaging back-current flow through the device during hot-swap, power sequencing, or subsystem sleep states - making it suitable for modular embedded systems such as enterprise tablets and network projector front ends.
What are the absolute maximum ratings for input voltage on SN74LVC1G07DSFR?
The absolute maximum input voltage (VI) for SN74LVC1G07DSFR is –0.5V to 6.5V, as defined in Section 5.1 of the datasheet. However, for reliable operation within recommended conditions, input voltage must remain within 0V to 5.5V - a limit enforced by internal clamp diodes and validated across the full temperature range.
