Diodes Incorporated 74LVC2G06FX4-7

Overview

74LVC2G06FX4-7 from Diodes Incorporated is a dual CMOS inverter with open-drain outputs, designed for level-shifting and wired-logic applications across 1.65V–5.5V supply rails. It features IOFF partial power-down protection, 5.5V-tolerant inputs, 32mA sink capability at 4.5V, and is packaged in the X2-DFN1409-6 (1.4mm × 0.9mm) chip-scale package.

For engineers reviewing the 74LVC2G06FX4-7 datasheet, 74LVC2G06FX4-7 pinout, 74LVC2G06FX4-7 application, or 74LVC2G06FX4-7 equivalent, key selection criteria include open-drain drive strength, voltage-level translation range, IOFF leakage performance, thermal resistance (θJA = 450°C/W), and compatibility with high-density PCB layouts requiring sub-1mm² footprint.

Technical Context

This device implements two independent inverting logic gates, each with an open-drain output enabling active-low wired-OR and active-high wired-AND bus configurations. Its IOFF circuitry actively disables outputs during power-down to prevent back-current flow, meeting JESD78 Class I latch-up immunity (>100mA).

Input voltage tolerance up to 5.5V allows interoperability between 1.8V, 2.5V, 3.3V, and 5V domains without external level shifters. Propagation delay is specified from 0.5ns (min) to 3.7ns (max) at VCC = 5V over –40°C to +125°C, with input transition rate support up to 20 ns/V at 1.8V.

FAQ

What is the maximum allowable sink current per output at 3.3V?

At VCC = 3.3V, the 74LVC2G06FX4-7 supports up to 24mA sink current per output (IOL), with a guaranteed VOL ≤ 0.60V. This is verified per DS35161 Rev. 6-2, page 4, under Recommended Operating Conditions at TA = –40°C to +125°C.

Can this device be used to translate 5V signals to a 1.8V microcontroller?

Yes-the inputs tolerate up to 5.5V regardless of VCC, so a 5V signal applied to 1A or 2A is safely recognized while the device operates from 1.8V. The open-drain outputs must be pulled up to the 1.8V domain to complete level translation.

Does the X2-DFN1409-6 package include a thermal pad?

No-the X2-DFN1409-6 package has six signal pads only (no exposed thermal pad). Thermal dissipation relies on copper traces connected to GND and VCC pads; θJA = 450°C/W is measured on standard FR-4 with minimum recommended pad layout per AP02002.

Is IOFF functionality active when VCC is disconnected but inputs remain biased?

Yes-IOFF activates automatically when VCC = 0V, disabling both outputs regardless of input voltage (up to 5.5V). This prevents current flow from externally biased inputs or outputs into the unpowered IC, satisfying JESD78 Class I latch-up immunity requirements.
