Product details
Overview
SN74LVC2G07DCKTG4 from Texas Instruments is a dual open-drain buffer IC designed for level translation and wired-OR logic implementation in 1.65-V to 5.5-V systems. It features two independent open-drain outputs capable of sinking up to 32 mA at 4.5 V, supports 5.5-V tolerant inputs, and delivers 3.7 ns max propagation delay at 3.3 V - enabling robust interface buffering in portable media players, SSDs, and GPS navigation devices.
For engineers reviewing the SN74LVC2G07DCKTG4 datasheet, SN74LVC2G07DCKTG4 pinout, SN74LVC2G07DCKTG4 application, or SN74LVC2G07DCKTG4 equivalent, key selection criteria include its Ioff-enabled partial-power-down capability, 6-pin SC70 package footprint, 5.5-V input tolerance for mixed-voltage domain interfacing, and verified open-drain sink performance across –40°C to 125°C.
Technical Context
The SN74LVC2G07DCKTG4 implements two non-inverting open-drain buffers with independent inputs (1A, 2A) and outputs (1Y, 2Y), requiring external pull-up resistors to establish high-level logic states. Its Ioff circuitry actively disables outputs during power-down, blocking back-drive current and supporting live insertion in hot-swap systems.
Input voltage tolerance up to 5.5 V enables bidirectional level translation between 1.8-V, 2.5-V, 3.3-V, and 5-V domains without external level shifters. The device operates across full industrial temperature range (–40°C to 125°C) with guaranteed VOL ≤ 0.55 V at IOL = 24 mA and VCC = 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports single-supply operation across common logic families including 1.8-V, 2.5-V, 3.3-V, and 5-V systems. |
| Max Sink Current | 32 mA per output at 4.5 V - enables direct driving of LEDs, I²C bus termination, or high-current wired-AND loads without external transistors. |
| tpd (Max) | 3.7 ns at VCC = 3.3 V - ensures timing-critical signal buffering in high-speed digital interfaces such as SSD control lines or display data paths. |
| Ioff Current | ±10 μA max - prevents damaging backflow when VCC = 0 V, critical for partial-power-down architectures in battery-powered embedded systems. |
| Input Tolerance | Up to 5.5 V regardless of VCC - allows safe interfacing with higher-voltage controllers while powered from lower VCC rails (e.g., 3.3-V supply with 5-V MCU GPIO). |
| ESD Rating | 2000-V HBM, 1000-V CDM - meets industrial-grade robustness requirements for handheld and automotive infotainment applications. |
Pinout & Package
SN74LVC2G07DCKTG4 uses the 6-pin SC70 (DCK) package measuring 2.00 mm × 1.25 mm, optimized for space-constrained PCB layouts in portable electronics. Pin 1 is located at the top-left corner with marking dot; tape-and-reel orientation follows quadrant Q3 per TI packaging specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input 1 | Non-inverting logic input for first buffer channel; accepts 0–5.5 V regardless of VCC value. |
| GND | Ground | Reference return path for all internal circuitry and output sink current; must be low-impedance connection. |
| 2A | Input 2 | Non-inverting logic input for second buffer channel; electrically isolated from 1A but shares same VCC/GND rails. |
| 2Y | Open-drain output 2 | Sinks current only; requires external pull-up to define high state; supports wired-OR with other open-drain devices. |
| VCC | Power supply | Supplies core logic and output driver; range 1.65–5.5 V; bypass capacitor required per layout guidelines. |
| 1Y | Open-drain output 1 | Independent open-drain output; compatible with I²C, SMBus, and interrupt line sharing in multi-master systems. |
Key Features
| Feature | Design Value |
|---|---|
| Dual open-drain configuration | Enables independent wired-OR logic on each output, allowing multiple devices to share a common interrupt or acknowledge line without contention. |
| Ioff partial-power-down support | Disables outputs and blocks reverse current flow when VCC = 0 V, permitting safe insertion into live backplanes or hot-swappable modules. |
| 5.5-V tolerant inputs | Eliminates need for external level translators when interfacing with legacy 5-V peripherals or mixed-voltage SoCs. |
| NanoFree™ package | SC70 footprint reduces board area by >50% vs. standard SOT-23, critical for ultra-thin mobile and wearable designs. |
| Low ICC (10 μA max) | Minimizes quiescent power draw in always-on subsystems such as GPS receivers or SSD standby controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DCKR | Single-channel version in identical SC70 package; same VCC range, Ioff, and 32-mA sink rating. | Requires two units for dual-buffer function; increases PCB area and BOM count vs. integrated dual-channel SN74LVC2G07DCKTG4. | Select when only one buffer channel is needed or when design modularity favors discrete channel assignment. |
| NC7WZ07P6X | Dual open-drain buffer from ON Semiconductor; 1.65–5.5 V operation, 32-mA sink, but no Ioff support and 5-V max input tolerance. | Lacks partial-power-down protection; unsuitable for hot-swap or multi-rail power-gating systems where back-drive risk exists. | Acceptable for fixed-power systems with stable VCC; avoid in battery-powered or modular embedded platforms requiring Ioff. |
