Product details
Overview
SN74LVC3G07DCTR 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 sink drive, and supports Ioff partial-power-down protection. Used in level-shifting, wired-OR logic, and bus interface applications where active-low pull-down control is required.
For engineers reviewing the SN74LVC3G07DCTR datasheet, SN74LVC3G07DCTR pinout, SN74LVC3G07DCTR application, or SN74LVC3G07DCTR equivalent, key selection criteria include open-drain compatibility with 5.5-V tolerant inputs, Ioff-enabled live insertion support, thermal performance in SSOP (DCT) package, and verified 32-mA max sink capability per channel.
Technical Context
This device implements three independent non-inverting buffers, each with an open-drain output stage capable of sinking up to 32 mA at 4.5 V. Its Ioff circuitry actively disables outputs during power-down, preventing back-drive current and enabling hot-plug operation.
The input structure accepts voltages up to 5.5 V regardless of VCC level, allowing seamless 1.8-V/3.3-V-to-5-V level translation. Propagation delay remains under 4.2 ns across –40°C to 125°C when VCC = 3.3 V, with typical VOL < 0.3 V at 8 mA sink load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - Enables interoperability across mixed-voltage systems including 1.8-V, 2.5-V, 3.3-V, and 5-V domains. |
| Max tpd | 3.7 ns at VCC = 3.3 V - Ensures timing-critical signal buffering with sub-4-ns latency in industrial-grade operation. |
| IOL Max | 32 mA at VCC = 4.5 V - Supports direct driving of LEDs, MOSFET gates, or multiple standard TTL loads without external pull-ups. |
| Ioff Current | ±10 μA max - Guarantees isolation between powered and unpowered system sections during partial power-down sequences. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe interfacing with higher-voltage controllers while operating from low VCC, eliminating external clamping diodes. |
| Operating Temp | –40°C to +125°C - Qualified for under-hood automotive, industrial motor control, and extended-temperature embedded applications. |
| Package | SSOP-8 (DCT) - 3.0 mm × 3.0 mm body, 0.65 mm pitch, 1.3 mm max height; compatible with standard reflow profiles and automated assembly. |
Pinout & Package
SN74LVC3G07DCTR uses the DCT (SSOP-8) package: 3.0 mm × 3.0 mm body, 0.65 mm lead pitch, 1.3 mm maximum height, with gull-wing leads and pin 1 marked by a beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | Channel 1 input - CMOS-compatible, 5.5-V tolerant, referenced to local VCC. |
| 2 | GND | Ground reference - Must be connected to system ground plane for stable noise margin and Ioff functionality. |
| 3 | 1Y | Channel 1 open-drain output - Requires external pull-up to define high state; sinks current only. |
| 4 | 2A | Channel 2 input - Electrically identical to 1A; supports independent signal routing. |
| 5 | 2Y | Channel 2 open-drain output - May be wire-OR'd with other open-drain outputs on same net. |
| 6 | 3A | Channel 3 input - Fully decoupled from channels 1 and 2; no internal crosstalk. |
| 7 | 3Y | Channel 3 open-drain output - Supports dedicated or shared bus termination per design requirement. |
| 8 | VCC | Power supply - Supplies internal logic and output driver stages; bypass capacitor recommended near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Open-drain outputs | Enable wired-OR logic, I²C/SMBus compatibility, and flexible pull-up voltage selection independent of VCC. |
| Ioff partial-power-down | Prevents current backflow when VCC = 0 V, supporting hot-swap and modular system architectures. |
| 5.5-V tolerant inputs | Eliminates need for external level shifters when interfacing with legacy 5-V microcontrollers or sensors. |
| NanoFree™ packaging | DCT package uses die-as-package construction, reducing parasitic inductance and improving thermal resistance (θJA = 220°C/W). |
| Latch-up immunity | Exceeds 100 mA per JESD 78 Class II - Ensures robustness against transient-induced latch-up in noisy environments. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G07DCUR | VSSOP-8 (DCU) package: 2.4 mm × 2.2 mm, 0.5 mm pitch, 0.9 mm height - 35% smaller footprint, higher thermal resistance (θJA = 227°C/W). | Better suited for space-constrained PCBs; requires tighter stencil aperture control due to finer pitch. | Choose DCUR for ultra-compact designs where board area is critical and thermal margin allows. |
| SN74LVC1G07DBVR | Single-channel version in SOT-23-5 package; identical electrical specs but only one buffer channel. | Used when only one open-drain buffer is needed - avoids unused channels and reduces BOM count. | Choose DBVR for point-of-load buffering or minimal-channel-count applications to reduce cost and layout complexity. |

FAQ
What is the maximum sink current per channel for SN74LVC3G07DCTR?
The SN74LVC3G07DCTR supports up to 32 mA sink current per output channel at VCC = 4.5 V, as specified in the Electrical Characteristics table under IOL conditions. This rating holds across the full operating temperature range (–40°C to +125°C), making SN74LVC3G07DCTR suitable for driving moderate-current loads like LEDs or MOSFET gates without external amplification.
Does SN74LVC3G07DCTR support partial power-down operation?
Yes, SN74LVC3G07DCTR includes Ioff circuitry that disables all outputs when VCC = 0 V, limiting off-state current to ±10 μA maximum. This feature prevents damaging current backflow during live insertion or partial system power-down, and is explicitly validated per JESD 78 Class II latch-up standards - a core design requirement for SN74LVC3G07DCTR in modular hardware.
Can SN74LVC3G07DCTR inputs safely accept 5-V signals while operating at 1.8-V VCC?
Yes, SN74LVC3G07DCTR inputs are rated for voltages up to 5.5 V regardless of VCC level, enabling reliable 5-V-to-1.8-V level translation without external components. This 5.5-V tolerance is guaranteed across –40°C to +125°C and is a defining specification of SN74LVC3G07DCTR, confirmed in both Absolute Maximum Ratings and Recommended Operating Conditions tables.
What is the propagation delay of SN74LVC3G07DCTR at 3.3-V operation?
At VCC = 3.3 V ± 0.3 V and TA = 25°C, SN74LVC3G07DCTR exhibits a typical propagation delay (tpd) of 3.7 ns, with a maximum of 4.2 ns over the full –40°C to +125°C temperature range. This value is measured from input transition (VCC/2) to output transition (VOL + ΔV), as defined in the Switching Characteristics section of the official datasheet for SN74LVC3G07DCTR.
Is SN74LVC3G07DCTR RoHS compliant and lead-free?
Yes, SN74LVC3G07DCTR is RoHS compliant and features lead-free terminal finish (NIPDAU | SN), as documented in TI's Packaging Information Addendum. It carries MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH) and is qualified for standard Pb-free reflow profiles up to 260°C peak temperature - fully aligned with IPC-J-STD-020 requirements for SN74LVC3G07DCTR.
