Product details
Overview
SN74LVC3G07DCT3 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, 10-μA max ICC, 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 SN74LVC3G07DCT3 datasheet, SN74LVC3G07DCT3 pinout, SN74LVC3G07DCT3 application, or SN74LVC3G07DCT3 equivalent, key selection considerations include open-drain output compatibility, Ioff-enabled live insertion support, 3.3-V/5-V mixed-voltage interfacing capability, and SSOP-8 package footprint constraints.
Technical Context
This device integrates three independent non-inverting buffers, each with an open-drain output stage capable of sinking up to 32 mA (IOL) 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 (1.65–5.5 V), enabling robust level translation. Output voltage swing is rail-to-rail relative to external pull-up, with VOL ≤ 0.55 V at IOL = 24 mA and VCC = 3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - Enables interoperability across 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains. |
| Max tpd | 3.7 ns at VCC = 3.3 V - Supports high-speed digital signaling in timing-critical interfaces. |
| IOL (max) | 32 mA at VCC = 4.5 V - Sinks sufficient current for driving LEDs, MOSFET gates, or multiple TTL loads. |
| Ioff Current | ±10 μA max - Ensures zero back-current flow during partial power-down, critical for system-level hot-swap safety. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - Allows direct connection to higher-voltage buses without external level shifters. |
| VOL (typ) | 0.3 V at IOL = 8 mA, VCC = 2.3 V - Guarantees strong low-state margin for noise-immune wired-OR bus operation. |
| ICC (max) | 10 μA - Minimizes quiescent power in battery-powered or always-on subsystems. |
Pinout & Package
SN74LVC3G07DCT3 uses an 8-pin SSOP (DCT) package with 1.3 mm maximum height, 0.65 mm lead pitch, and standard SOIC-compatible land pattern. Pin 1 is located in quadrant Q3 per tape-and-reel orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Buffer input | Three independent CMOS-compatible inputs accepting 0–5.5 V; no internal pull-up/down. |
| 1Y, 2Y, 3Y | Open-drain output | Three independent NMOS drain terminals requiring external pull-up; sink-only operation. |
| VCC | Power supply | Single supply rail for all logic and output stages; powers internal circuitry and defines VIH/VIL thresholds. |
| GND | Ground reference | Common return path for supply current and output sink current; must be low-impedance for noise control. |
Key Features
| Feature | Design Value |
|---|---|
| Open-drain outputs | Enable wired-OR logic and bidirectional bus arbitration without external components. |
| Ioff partial-power-down | Prevents current backflow when VCC = 0 V, supporting hot-plug and dynamic power gating. |
| NanoFree™ packaging | DCT package uses die-as-package construction, reducing size and thermal resistance vs. traditional SOIC. |
| 5-V tolerant inputs | Accepts 0–5.5 V signals at any valid VCC (1.65–5.5 V), simplifying mixed-voltage interconnect design. |
| Low ground bounce (VOLP) | Typical <0.8 V at VCC = 3.3 V - Maintains signal integrity during simultaneous switching. |
Applications
| Level-Shifting Interface | Wired-OR Bus Control |
|---|---|
Use Scenario: Interfacing a 3.3-V microcontroller GPIO to a 5-V I²C bus or legacy parallel control line. IC Role / Device Role / Timing Role: Non-inverting open-drain buffer providing voltage-domain isolation and sink-only drive. Use Value: Eliminates need for discrete MOSFET translators; leverages internal 5-V-tolerant inputs and configurable external pull-up voltage. |
Use Scenario: Implementing shared interrupt or reset lines across multiple peripherals on a single PCB. IC Role / Device Role / Timing Role: Three-channel wired-OR driver enabling multi-source active-low assertion with automatic bus arbitration. Use Value: Reduces component count versus discrete diode-OR networks; ensures consistent VOL and fast release time via controlled NMOS turn-off. |
| LED Driver Interface | Power Sequencing Control |
Use Scenario: Driving common-anode status LEDs from low-voltage logic with adjustable brightness via external series resistor. IC Role / Device Role / Timing Role: Current-sinking buffer controlling LED cathode connection to GND. Use Value: Delivers up to 24 mA per channel at 3.3 V - sufficient for indicator LEDs without external transistors. |
Use Scenario: Enabling/disabling power rails in sequence using microcontroller-controlled enable signals with fail-safe default-off behavior. IC Role / Device Role / Timing Role: Open-drain output driving gate of external high-side PMOS FET or enable pin of downstream regulator. Use Value: Ioff protection prevents backfeed into powered-down MCU; open-drain allows pull-up to higher rail than VCC for flexible control voltage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G06DCT3 | Inverting logic function; identical pinout, specs, and package. | Requires logic inversion in signal path; unsuitable where polarity must be preserved. | Select SN74LVC3G06DCT3 only when active-low output behavior aligns with system timing or control requirements. |
| SN74LV3G07DCT3 | Lower VCC range (2.0–5.5 V); no 1.65-V support; slightly higher tpd (4.2 ns @ 3.3 V). | Not suitable for 1.8-V systems or ultra-low-voltage operation; reduced process node margin. | Choose SN74LV3G07DCT3 only if operating exclusively above 2.0 V and cost sensitivity outweighs 1.65-V compatibility needs. |
Compared with SN74LVC3G07DCT3, SN74LVC3G06DCT3 provides functional inversion at identical performance and footprint, while SN74LV3G07DCT3 trades 1.65-V operation and 0.5-ns speed advantage for marginal cost reduction in 2.5-V+ applications.

FAQ
What is the maximum sink current capability of SN74LVC3G07DCT3 at 3.3 V?
The SN74LVC3G07DCT3 guarantees a minimum sink current (IOL) of 24 mA at VCC = 3.3 V and VOL ≤ 0.55 V, with absolute maximum rating of ±50 mA per output. This enables direct driving of moderate-current loads such as LEDs or logic inputs without external amplification.
Does SN74LVC3G07DCT3 support partial power-down operation?
Yes, SN74LVC3G07DCT3 incorporates Ioff circuitry that disables all outputs when VCC = 0 V, limiting off-state current to ±10 μA max. This feature protects against back-current flow during hot-insertion or staggered power sequencing, making SN74LVC3G07DCT3 suitable for live-system upgrades.
Can SN74LVC3G07DCT3 interface between 1.8-V and 5-V logic domains?
Yes, SN74LVC3G07DCT3 accepts input voltages up to 5.5 V regardless of VCC level (1.65–5.5 V), and its open-drain outputs can be pulled up to any voltage ≤ 5.5 V. When VCC = 1.8 V, SN74LVC3G07DCT3 safely translates 5-V inputs to 1.8-V-compatible control signals using an external 5-V pull-up.
What is the propagation delay of SN74LVC3G07DCT3 at 5 V VCC?
At VCC = 5 V ± 0.5 V and TA = –40°C to 85°C, SN74LVC3G07DCT3 exhibits a maximum propagation delay (tpd) of 2.9 ns (A to Y). This value is measured under standard load conditions (CL = 50 pF, RL = 500 Ω) and confirms SN74LVC3G07DCT3's suitability for sub-350-MHz digital timing paths.
Is SN74LVC3G07DCT3 available in RoHS-compliant packaging?
Yes, SN74LVC3G07DCT3 is RoHS-compliant (lead-free) with SNBI lead finish and meets JEDEC Level-1 moisture sensitivity standards. The DCT package is supplied in large tape-and-reel format (3000 units/reel), fully compatible with automated SMT assembly processes.
