Diodes Incorporated 74LVC2G07FW5-7

Overview

74LVC2G07FW5-7 from Diodes Incorporated is a dual CMOS buffer 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 at 4.5V, and is packaged in a 1.0mm × 1.0mm × 0.5mm X1-DFN1010-6 leadless package - used in notebook I/O expansion and SSD power sequencing.

For engineers reviewing the 74LVC2G07FW5-7 datasheet, 74LVC2G07FW5-7 pinout, 74LVC2G07FW5-7 application, or 74LVC2G07FW5-7 equivalent, this page provides verified functional specifications, validated pin assignments, confirmed package dimensions, and real-world use cases in level-shifting and power-down isolation circuits.

Technical Context

This device implements two independent non-inverting buffers, each with an open-drain output stage enabling wired-OR logic and bidirectional voltage translation. Its IOFF circuit actively disables both outputs during power-down, preventing back-current flow when VCC = 0V while inputs or outputs remain biased at up to 5.5V.

The input structure supports 5.5V tolerance across the full 1.65V–5.5V supply range, and propagation delay is specified from 0.5ns (min) to 3.7ns (max) at VCC = 3.3V with CL = 30pF, confirming suitability for high-speed digital interface buffering in portable electronics.

FAQ

Can 74LVC2G07FW5-7 drive a 10kΩ pull-up resistor on a 3.3V I²C bus?

Yes. At VCC = 3.3V and IOL = 3mA, VOL is guaranteed ≤0.4V, yielding a valid logic-low voltage margin of >2.9V. With 32mA maximum sink capability, it comfortably drives standard 10kΩ pull-ups even under worst-case process/voltage/temperature corners.

What happens to the outputs when VCC = 0V and inputs are held at 3.3V?

The IOFF circuit disables both outputs, limiting leakage current to ±20μA maximum. This prevents damaging back-current flow from the 3.3V inputs into the unpowered VCC rail - a key requirement for hot-swap and battery-backed subsystems.

Is the X1-DFN1010-6 package compatible with standard reflow profiles for lead-free soldering?

Yes. The package is fully RoHS-compliant and qualified for JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260°C. Its 0.35mm pad pitch and bottom thermal pad require precise stencil design but are supported by mainstream SMT lines.

How does propagation delay vary with supply voltage and load capacitance?

tPD decreases as VCC increases: 3.7ns max at 3.3V/30pF, 2.9ns max at 5V/30pF. It increases linearly with load capacitance - e.g., at 50pF and 3.3V, tPD max rises to 4.7ns. These values are measured per Figure 1 load circuit in the datasheet.
