Diodes Incorporated 74LVC2G07FX4-7

Overview

74LVC2G07FX4-7 from Diodes Incorporated is a dual buffer IC with open-drain outputs, designed for voltage-level shifting and signal isolation in mixed-voltage systems. It operates from 1.65V to 5.5V, tolerates 5.5V inputs, supports IOFF partial power-down mode, delivers up to 32mA sink current per output, and is packaged in X2-DFN1409-6 (1.4mm × 0.9mm, 0.5mm pad pitch).

For engineers reviewing the 74LVC2G07FX4-7 datasheet, 74LVC2G07FX4-7 pinout, 74LVC2G07FX4-7 application, or 74LVC2G07FX4-7 equivalent, this device serves as a compact, RoHS-compliant logic buffer for I²C bus interfacing, power-down signal routing, and bidirectional level translation in space-constrained portable electronics.

Technical Context

This dual buffer implements two independent non-inverting gates with open-drain outputs, enabling wired-OR and wired-AND configurations. Its IOFF circuitry actively disables outputs during power-down, preventing back-current flow when VCC = 0V.

Input voltage tolerance up to 5.5V allows interfacing with higher-voltage logic while powered from lower supply rails (e.g., 1.8V or 3.3V). Propagation delay is ≤3.7ns at VCC = 3.3V and ≤3.7ns at TA = –40°C to +125°C, supporting reliable timing in high-speed digital subsystems.

FAQ

Can 74LVC2G07FX4-7 be used as a level shifter between 1.8V and 5V domains?

Yes. Its 5.5V-tolerant inputs allow direct connection to 5V signals while operating from a 1.8V supply. The open-drain outputs require external pull-up to the higher voltage domain (e.g., 5V), enabling true bidirectional level translation without direction control pins.

Does the IOFF feature work when VCC is disconnected entirely?

Yes. When VCC is at 0V, the IOFF circuitry automatically disables both outputs, limiting leakage current to ±20μA. This prevents back-current flow from powered downstream circuits into the unpowered IC, protecting both sides during hot-plug or partial-power-down sequences.

What is the maximum capacitive load the 74LVC2G07FX4-7 can drive reliably?

Test data shows stable operation with CL ≤ 50pF at VCC = 3.3V and TA = +125°C. Rise time remains within spec (≤10ns) up to this load. For heavier loads (>50pF), propagation delay increases and may exceed timing budgets-external buffering or reduced trace length is recommended.

Is the X2-DFN1409-6 package compatible with standard reflow profiles?

Yes. The package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260°C, 60s above 217°C). Its 0.5mm pad pitch and exposed thermal pad require precise stencil aperture design and alignment verification during SMT setup.
