Product details
Overview
SN74LVC3G07DCURE4 from Texas Instruments is a triple non-inverting buffer/driver with open-drain outputs, designed for 1.65-V to 5.5-V VCC operation. It delivers 3.7 ns max propagation delay at 3.3 V, ±24-mA output drive capability, and supports Ioff partial-power-down protection. It is used in level-shifting, wired-OR logic, and bus interface applications where active-low pull-down control is required.
For engineers reviewing the SN74LVC3G07DCURE4 datasheet, SN74LVC3G07DCURE4 pinout, SN74LVC3G07DCURE4 application, or SN74LVC3G07DCURE4 equivalent, key selection considerations include open-drain sink current (32 mA max), Ioff-enabled live insertion support, voltage-tolerant inputs up to 5.5 V, and compatibility with mixed-voltage system interfacing across 1.65–5.5 V domains.
Technical Context
This device implements three independent non-inverting buffer stages, each with an open-drain output requiring external pull-up. Its Ioff circuitry disables all outputs when VCC = 0 V, preventing back-drive current during hot insertion or partial power-down. Input thresholds are VIL ≤ 0.3×VCC and VIH ≥ 0.7×VCC across the full 1.65–5.5 V supply range.
The SN74LVC3G07DCURE4 operates from –40°C to +125°C and features ±24-mA sink drive at 3.3 V, 10-μA max ICC, and input/output voltage tolerance up to 6.5 V (absolute max). Its NanoFree™ packaging uses the die as the package, enabling ultra-small footprint in DCU (VSSOP-8) form.

Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G07DCUT | Same silicon, identical electrical specs; differs only in tape-and-reel quantity (250 vs. 3000 units) | No functional difference; suitable for prototyping or low-volume production runs | Select SN74LVC3G07DCUT when small-batch evaluation or quick-turn assembly is required |
| SN74LVC3G07DCTR | Same functionality and pinout; packaged in SSOP-8 (DCT) instead of VSSOP-8 (DCU); 1.3-mm height vs. 0.9-mm | Requires larger PCB footprint and different stencil design; better thermal dissipation at high sink currents | Choose SN74LVC3G07DCTR if board layout accommodates SSOP or thermal performance outweighs size constraints |
Compared with SN74LVC3G07DCURE4, SN74LVC3G07DCUT offers identical performance in smaller reels for development, while SN74LVC3G07DCTR trades miniaturization for easier handling and marginally improved thermal resistance - both retain full functional and timing equivalence.

FAQ
What is the maximum sink current supported by each output of the SN74LVC3G07DCURE4?
Each output of the SN74LVC3G07DCURE4 supports up to 32 mA sink current at VCC = 4.5 V, with derating to 24 mA at 3.3 V, 16 mA at 2.3 V, and 8 mA at 1.65 V. This is specified under IOL in the Recommended Operating Conditions table. The SN74LVC3G07DCURE4 maintains consistent open-drain behavior across its full 1.65–5.5 V supply range, making it suitable for driving LEDs, MOSFET gates, or wired-logic buses.
Does the SN74LVC3G07DCURE4 support partial power-down operation?
Yes, the SN74LVC3G07DCURE4 integrates Ioff circuitry that disables all outputs when VCC = 0 V, limiting off-state current to ±10 μA max. This prevents damaging back-current flow during hot insertion, power sequencing, or partial system shutdown. The Ioff feature is explicitly validated in the Electrical Characteristics table and applies to the SN74LVC3G07DCURE4 across its full operating temperature range (–40°C to +125°C).
Can the inputs of the SN74LVC3G07DCURE4 tolerate 5-V signals while operating at 1.8-V VCC?
Yes, the SN74LVC3G07DCURE4 inputs accept voltages up to 5.5 V regardless of VCC level - a key specification confirmed in the Absolute Maximum Ratings and Features list. This allows direct interfacing with 5-V peripherals while the SN74LVC3G07DCURE4 runs from a 1.8-V supply, eliminating external level shifters in mixed-voltage systems.
What is the propagation delay of the SN74LVC3G07DCURE4 at 3.3-V operation?
The SN74LVC3G07DCURE4 has a maximum propagation delay (tpd) of 3.7 ns at VCC = 3.3 V ± 0.3 V, TA = –40°C to +85°C, as specified in the Switching Characteristics table. At extended temperature (–40°C to +125°C), tpd increases to 4.2 ns max. This value is measured from input transition (1.65 V) to output transition (VCC/2) under 30-pF load conditions.
Which package type does the SN74LVC3G07DCURE4 use, and what are its key mechanical dimensions?
The SN74LVC3G07DCURE4 uses the VSSOP-8 (DCU) package: 2.1 mm × 1.9 mm body size, 0.5-mm lead pitch, and 0.9-mm maximum height. Mechanical drawings confirm pin 1 orientation in quadrant Q3 of the tape reel. This ultra-compact package aligns with TI's NanoFree™ technology, where the silicon die functions as the package substrate - reducing parasitic inductance and enabling high-density routing.
