Texas Instruments SN74LVC2G07DCKRG4

Overview

SN74LVC2G07DCKRG4 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 use in I²C bus buffering, LED driving, and mixed-voltage interface isolation.

For engineers reviewing the SN74LVC2G07DCKRG4 datasheet, SN74LVC2G07DCKRG4 pinout, SN74LVC2G07DCKRG4 application, or SN74LVC2G07DCKRG4 equivalent, key selection criteria include open-drain drive strength, Ioff-enabled partial-power-down capability, 5.5-V input tolerance across VCC range, and SC70-6 package compatibility with space-constrained portable designs.

Technical Context

The SN74LVC2G07DCKRG4 implements two non-inverting open-drain buffers with no internal pull-up; external resistors define output high voltage and translation direction. Its Ioff circuitry actively disables outputs during power-down, blocking back-current flow and supporting live insertion in hot-swap systems.

Each channel operates independently with rail-to-rail input tolerance (0–5.5 V), allowing bidirectional level shifting between 1.8-V, 2.5-V, 3.3-V, and 5-V domains. The device meets JESD 78 Class II latch-up immunity (>100 mA) and exceeds JEDEC ESD standards: 2000-V HBM, 1000-V CDM.

FAQ

What is the maximum sink current capability of the SN74LVC2G07DCKRG4 at 3.3 V?

The SN74LVC2G07DCKRG4 can sink up to 24 mA per output at VCC = 3.3 V while maintaining VOL ≤ 0.55 V, as specified in the Electrical Characteristics table under IOL test conditions. This value is confirmed across –40°C to 125°C operating temperature range and supports robust LED driving and bus termination.

Does the SN74LVC2G07DCKRG4 support level translation between 1.8-V and 5-V logic domains?

Yes, the SN74LVC2G07DCKRG4 supports bidirectional level translation: its inputs tolerate 0–5.5 V regardless of VCC, and its open-drain outputs rely on external pull-up voltage. When powered from 1.8 V with a 5-V pull-up, it translates 1.8-V logic highs to 5-V bus levels - verified in TI's Application and Implementation section.

Is the SN74LVC2G07DCKRG4 pin-compatible with other packages in the SN74LVC2G07 family?

No - SN74LVC2G07DCKRG4 uses the SC70-6 (DCK) package, which has different pinout and footprint than SOT-23 (DBV), SON (DRY/DSF), or DSBGA (YZP) variants. While functionally identical, mechanical compatibility requires matching package-specific layout and soldering profiles.

What is the purpose of the Ioff feature in the SN74LVC2G07DCKRG4?

The Ioff feature disables both outputs when VCC = 0 V, limiting input/output leakage to ±10 μA. This prevents current backflow from live buses into a powered-down SN74LVC2G07DCKRG4 - essential for hot-swap compliance and avoiding damage in multi-rail systems where supplies sequence independently.

Can the SN74LVC2G07DCKRG4 be used in wired-AND configurations?

Yes - because both outputs are open-drain, connecting 1Y and 2Y together with a shared pull-up resistor creates a wired-AND function: the combined node goes low if either input is high. TI's Functional Block Diagram and Feature Description explicitly confirm this capability for active-high wired-AND implementation.
