Product details
Overview
SN74LVC3G07DCTRG4 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. It enables wired-OR logic in level-shifting I²C, SMBus, and GPIO expansion applications.
For engineers reviewing the SN74LVC3G07DCTRG4 datasheet, SN74LVC3G07DCTRG4 pinout, SN74LVC3G07DCTRG4 application, or SN74LVC3G07DCTRG4 equivalent, key selection criteria include open-drain compatibility with 5.5-V tolerant inputs, Ioff-enabled live insertion, thermal performance in VSSOP (DCU) package, and 32-mA max sink capability under 4.5-V VCC.
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-current flow when VCC = 0 V.
The input structure accepts voltages up to 5.5 V regardless of VCC level, enabling seamless 1.8-V/3.3-V-to-5-V level translation. Propagation delay remains stable across 1.65–5.5 V supply range, with typical tpd of 3.7 ns at 3.3 V and 25°C.
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 3.3 V - Ensures timing-critical signal buffering with sub-4-ns latency in high-speed digital interfaces. |
| IOL Max | 32 mA at 4.5 V - Supports direct driving of LEDs, pull-up networks, or multiple standard TTL loads without external transistors. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe interfacing with higher-voltage controllers while powered from lower VCC (e.g., 1.8-V supply). |
| Ioff Current | ±10 μA max - Guarantees isolation during hot-swap or partial-power-down, protecting upstream logic from backfeed. |
| ESD Rating | HBM: 2000 V - Meets industrial-grade robustness requirements for handling and board-level reliability. |
Pinout & Package
VSSOP (DCU) 8-pin package: 2.3 mm × 2.0 mm footprint, 0.5-mm pitch, 0.9-mm max height, exposed pad optional per layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Input) | First buffer input - accepts 0–5.5 V logic levels independent of VCC; compatible with mixed-supply signaling. |
| 2 | GND | Ground reference - must be low-impedance connection; shared return path for all three buffers. |
| 3 | 1Y (Output) | Open-drain output of Buffer 1 - requires external pull-up; sinks current only; no active high drive. |
| 4 | 2A (Input) | Second buffer input - electrically identical to Pin 1; supports independent signal routing. |
| 5 | 2Y (Output) | Open-drain output of Buffer 2 - isolated from other outputs; enables independent wired-OR node creation. |
| 6 | 3A (Input) | Third buffer input - fully decoupled from Inputs 1 and 2; allows three-channel signal conditioning. |
| 7 | 3Y (Output) | Open-drain output of Buffer 3 - supports dedicated bus arbitration or interrupt line control. |
| 8 | VCC | Supply voltage - powers internal logic; Ioff protection activates when VCC = 0 V. |
Key Features
| Feature | Design Value |

FAQ
What is the maximum sink current supported by SN74LVC3G07DCTRG4 at 5-V VCC?
The SN74LVC3G07DCTRG4 supports up to 32 mA sink current at 4.5 V VCC per output, as specified in the Recommended Operating Conditions table. At exactly 5 V, the datasheet does not list a tested IOL value; design margin should rely on the 4.5-V rating, and actual performance may vary slightly due to process variation. Always verify with load testing under final operating conditions for SN74LVC3G07DCTRG4.
Can SN74LVC3G07DCTRG4 be used in a 5-V-only system with 5-V inputs and outputs?
Yes - SN74LVC3G07DCTRG4 accepts input voltages up to 5.5 V regardless of VCC level, and its open-drain outputs can be pulled up to 5 V. When VCC = 5 V, it operates within full specification: tpd ≤ 2.9 ns, IOL = 32 mA, and VOL ≤ 0.75 V. The SN74LVC3G07DCTRG4 is fully compatible with 5-V logic families when configured with appropriate external pull-ups.
Does SN74LVC3G07DCTRG4 support hot-swap or live-insertion applications?
Yes - SN74LVC3G07DCTRG4 incorporates Ioff circuitry that disables outputs when VCC = 0 V, limiting off-state current to ±10 μA max. This prevents back-current flow from powered downstream circuits into the unpowered IC, satisfying live-insertion requirements. The SN74LVC3G07DCTRG4 is explicitly characterized for partial-power-down mode per JESD78 Class II latch-up standards.
What is the thermal resistance θJA for SN74LVC3G07DCTRG4 in its VSSOP (DCU) package?
The VSSOP (DCU) package for SN74LVC3G07DCTRG4 has a θJA of 227°C/W, as documented in the Absolute Maximum Ratings table. This value assumes standard JEDEC test board conditions (single-layer copper, 1-in² copper area). Actual thermal performance in end equipment depends on PCB layout, copper pour, airflow, and adjacent heat sources - derating is recommended for sustained 125°C ambient operation of SN74LVC3G07DCTRG4.
Is SN74LVC3G07DCTRG4 pin-compatible with other members of the SN74LVC3Gxx family?
No - SN74LVC3G07DCTRG4 is not pin-compatible with other SN74LVC3Gxx variants such as SN74LVC3G14 (inverter) or SN74LVC3G17 (Schmitt-trigger buffer), despite sharing the same VSSOP-8 (DCU) footprint. Pin functions differ: SN74LVC3G07DCTRG4 uses Pins 1/3/4/5/6/7 for A/Y pairs and GND/VCC, whereas others assign different logic functions and terminal roles. Always verify pin mapping against the specific device's datasheet for SN74LVC3G07DCTRG4.
