Product details
Overview
SN74LVC3G07DCUT 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 24-mA sink drive at 3.3 V, achieves 3.7-ns max propagation delay at 3.3 V, and supports Ioff partial-power-down protection. It is used in level-shifting interfaces between mixed-voltage logic domains in portable instrumentation and industrial control I/O expansion.
For engineers reviewing the SN74LVC3G07DCUT datasheet, SN74LVC3G07DCUT pinout, SN74LVC3G07DCUT application, or SN74LVC3G07DCUT equivalent, key selection considerations include open-drain wired-OR capability, ±24-mA output sink strength at 3.3 V, Ioff-enabled live insertion support, 1.65–5.5-V supply flexibility, and VSSOP (DCU) 8-pin package compatibility with space-constrained PCB layouts.
Technical Context
This device implements three independent non-inverting buffer stages, each with an open-drain output stage capable of sinking up to 32 mA. Its Ioff circuitry actively disables outputs during power-down, preventing back-current flow when VCC = 0 V - critical for hot-swap and partial-power-down systems.
The input structure accepts voltages up to 5.5 V regardless of VCC level, enabling robust level translation from 5-V logic to lower-voltage domains. All inputs are TTL-compatible and tolerate overvoltage conditions within absolute maximum ratings, supporting interoperability across legacy and modern logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables single-supply operation across 1.8-V, 2.5-V, 3.3-V, and 5-V logic systems |
| Max tpd @ 3.3 V | 3.7 ns - ensures timing-critical signal buffering in high-speed digital interfaces |
| IOL @ 3.3 V | 24 mA - provides sufficient sink current to drive LEDs, pull-up resistors, or MOSFET gates directly |
| Ioff Current | ±10 μA max - guarantees isolation during power sequencing and prevents backfeeding in multi-rail systems |
| Input Voltage Range | –0.5 V to 6.5 V - allows safe interfacing with 5-V signals even when VCC = 1.8 V |
| ESD Rating | 2000-V HBM - meets industrial-grade robustness requirements without external protection |
| Operating Temp | –40°C to +125°C - supports deployment in extended-temperature industrial and automotive-adjacent environments |

VSSOP (DCU) 8-pin package: ultra-thin (0.9 mm max height), 2.4 mm × 2.1 mm body, 0.5-mm pitch, exposed pad optional, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Buffer Input | Three independent logic inputs accepting 0–5.5 V; TTL-compatible thresholds scale with VCC |
| 1Y, 2Y, 3Y | Open-Drain Output | Three independent open-drain outputs - require external pull-up for active-high logic; support wired-AND/OR |
| VCC | Power Supply | Single positive supply rail (1.65–5.5 V); powers internal logic and Ioff circuitry |
| GND | Ground Reference | Primary return path for all internal currents and I/O reference; must be low-impedance |
Key Features

|---|---|
| Open-drain outputs | Enable wired-logic functions (e.g., I²C bus pull-up, interrupt line aggregation) without external diodes |
| Ioff partial-power-down | Prevents current backflow when VCC = 0 V - essential for hot-plug and multi-supply system reliability |
| NanoFree™ packaging | Dies serve as packages - eliminates bond wires and leadframe, reducing parasitics and footprint by >50% vs. SSOP |
| 5.5-V tolerant inputs | Allows direct connection to 5-V microcontrollers or sensors without level-shifters in mixed-voltage designs |
| Low ICC (10 μA max) | Minimizes quiescent power in battery-powered applications such as handheld test equipment and sensor nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G07DCUR | Same electrical specs; identical VSSOP (DCU) package but supplied in 3000-unit tape-and-reel vs. 250-unit small reel | No functional difference; optimized for high-volume production rather than prototyping or low-MOQ procurement | Select SN74LVC3G07DCUR for cost-sensitive volume builds; SN74LVC3G07DCUT suits evaluation and pilot runs. |
| SN74LVC1G07DBVR | Single-channel version in SOT-23-5; shares same VCC range, Ioff, and open-drain architecture but only one buffer | Used where only one buffered open-drain output is required - saves board area but lacks triple functionality | Choose SN74LVC1G07DBVR when design requires only one channel and minimal footprint; SN74LVC3G07DCUT is optimal for multi-signal buffering. |
Compared with SN74LVC3G07DCUR, SN74LVC3G07DCUT offers identical performance in a smaller reel format ideal for NPI and qualification; versus SN74LVC1G07DBVR, it provides three independent channels in the same DCU footprint - delivering 200% functional density without increasing layout area.

FAQ
What is the maximum sink current capability of the SN74LVC3G07DCUT at 3.3 V?
The SN74LVC3G07DCUT guarantees a minimum sink current (IOL) of 24 mA at VCC = 3.3 V, with typical performance reaching 32 mA under specified test conditions. This rating applies per output channel (1Y, 2Y, or 3Y), and all three channels can operate simultaneously within thermal limits defined by θJA = 227°C/W for the DCU package. The device remains within safe operating area up to 50 mA absolute maximum per output.
Does the SN74LVC3G07DCUT support level shifting between 5-V and 3.3-V logic domains?
Yes, the SN74LVC3G07DCUT supports bidirectional level shifting in open-drain configurations. Its inputs accept voltages up to 5.5 V regardless of VCC level, allowing 5-V signals to safely drive the 1A/2A/3A inputs when VCC = 3.3 V. Outputs are open-drain and require external pull-up to the higher-voltage domain (e.g., 5 V), enabling the SN74LVC3G07DCUT to translate 3.3-V logic outputs to 5-V bus levels without additional components.
Can the SN74LVC3G07DCUT be used in hot-swap applications?
Yes, the SN74LVC3G07DCUT is explicitly designed for hot-swap use via its Ioff feature. When VCC = 0 V, the Ioff circuitry disables all outputs and limits leakage to ±10 μA, preventing damaging back-current flow from live system rails into the unpowered device. This behavior is verified per JESD78 Class II latch-up standards and supports safe insertion/removal in powered-backplane systems - a key requirement validated in the SN74LVC3G07DCUT datasheet Section 6.5.
What is the propagation delay of the SN74LVC3G07DCUT at 1.8 V supply?
At VCC = 1.8 V ± 0.15 V, the SN74LVC3G07DCUT exhibits a maximum propagation delay (tpd) of 7.8 ns over –40°C to +85°C, and 8.3 ns over –40°C to +125°C, as specified in the Switching Characteristics tables. This delay is measured from input transition (10% to 90%) to output transition (10% to 90%) under standard load conditions (CL = 30 pF, RL = 1 kΩ). The typical value at 25°C is 1.5 ns.
Is the SN74LVC3G07DCUT pin-compatible with other members of the SN74LVC3Gxx series?
No, the SN74LVC3G07DCUT is not universally pin-compatible across the SN74LVC3Gxx series. While it shares the same VSSOP (DCU) 8-pin footprint with SN74LVC3G14 (Schmitt-trigger inverter) and SN74LVC3G17 (buffer), pin assignments differ: SN74LVC3G07DCUT uses pins 1/3/5 for inputs and 2/4/6 for outputs, whereas SN74LVC3G14 assigns inputs to pins 1/3/5 and outputs to pins 2/4/6 but inverts logic. Always verify pin mapping against the specific device's datasheet - the SN74LVC3G07DCUT pinout is fixed per Figure 1 in SCES365K.
