Texas Instruments SN74LVC2G07YEAR

Overview

SN74LVC2G07YEAR 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 delivers 32-mA sink current per output at 4.5 V, supports 5.5-V tolerant inputs, and achieves 3.7-ns propagation delay at 3.3 V - enabling robust I²C bus buffering, LED driving, and mixed-voltage interface isolation in portable and embedded applications.

For engineers reviewing the SN74LVC2G07YEAR datasheet, SN74LVC2G07YEAR pinout, SN74LVC2G07YEAR application, or SN74LVC2G07YEAR equivalent, key selection criteria include open-drain drive strength, Ioff-enabled partial-power-down capability, 5.5-V input tolerance for voltage translation, and NanoFree™ package compatibility with high-density PCB layouts.

Technical Context

The SN74LVC2G07YEAR implements two independent open-drain buffers with no internal pull-up; external resistors define logic-high voltage and enable bidirectional level shifting between domains (e.g., 1.8-V MCU to 3.3-V peripheral). Its Ioff circuitry actively disables outputs during power-down, blocking back-drive current and supporting live insertion in hot-swap systems.

Each buffer operates across –40°C to 125°C with guaranteed VOL ≤ 0.55 V at 24 mA/3.3 V and ICC ≤ 10 μA static supply current. Input transition rate limits (5–20 ns/V) and ESD robustness (2000-V HBM) are specified to ensure signal integrity in noisy industrial and mobile environments.

Key Specifications

Pinout & Package

SN74LVC2G07YEAR is available in Texas Instruments' NanoFree™ DSBGA (YZP) package: 1.41 mm × 0.91 mm, 6-pin bottom-terminal die-scale ball grid array. This ultra-compact footprint eliminates wire bonds and lead frames, reducing parasitic inductance and improving thermal performance in space-constrained layouts.

FAQ

What is the maximum sink current supported by SN74LVC2G07YEAR at 3.3 V?

The SN74LVC2G07YEAR supports up to 24 mA sink current per output at 3.3 V while maintaining VOL ≤ 0.55 V, as specified in the Electrical Characteristics table under IOL test conditions. This rating ensures reliable operation when driving standard LEDs or terminating I²C bus lines with typical 2.2-kΩ pull-ups.

Does SN74LVC2G07YEAR support partial-power-down operation?

Yes, SN74LVC2G07YEAR incorporates Ioff circuitry that disables outputs when VCC = 0 V, limiting Ioff current to ±10 μA. This feature prevents damaging back-current flow during hot-swap or partial-power-down scenarios - a key requirement for modular systems and field-replaceable units.

Can SN74LVC2G07YEAR translate between 1.8-V and 5-V logic levels?

Yes, SN74LVC2G07YEAR supports bidirectional level translation: its inputs tolerate up to 5.5 V regardless of VCC, and its open-drain outputs can be pulled up to any voltage ≤ 5.5 V. When powered from 1.8 V, it reliably drives 5-V buses using external pull-ups - enabling seamless 1.8-V-to-5-V interface bridging.

What package type is used for SN74LVC2G07YEAR?

SN74LVC2G07YEAR uses the YZP package - a 6-pin DSBGA (Die Size Ball Grid Array) measuring 1.41 mm × 0.91 mm. This NanoFree™ package places solder balls directly on the silicon die, eliminating leads and wire bonds to minimize parasitics and maximize board density.

Is SN74LVC2G07YEAR compatible with I²C bus standards?

Yes, SN74LVC2G07YEAR meets I²C electrical requirements: its open-drain outputs support wired-AND topology, 5.5-V input tolerance accommodates 5-V masters/slaves, and 3.7-ns tpd at 3.3 V ensures timing compliance up to 400-kHz Fast Mode. External pull-ups must be selected per bus capacitance and speed targets.
