Diodes Incorporated 74LVC1G06FW5-7

Overview

74LVC1G06FW5-7 from Diodes Incorporated is a single CMOS inverter buffer with open-drain output, designed for level-shifting and signal isolation in mixed-voltage systems. It operates from 1.65V to 5.5V, accepts 5.5V-tolerant inputs, supports IOFF partial power-down mode, delivers up to 32mA sink current at 4.5V, and uses the X1-DFN1010-6 (Type B) 1.0mm × 1.0mm package - deployed in notebook I/O control and USB peripheral interface circuits.

For engineers reviewing the 74LVC1G06FW5-7 datasheet, 74LVC1G06FW5-7 pinout, 74LVC1G06FW5-7 application, or 74LVC1G06FW5-7 equivalent, key selection criteria include open-drain drive capability, 5.5V input tolerance, IOFF-enabled power-down isolation, and thermal resistance (θJA = 435°C/W) in ultra-compact DFN packaging.

Technical Context

This device implements a single inverting logic gate with open-drain output topology, enabling wired-OR/AND bus configurations and bidirectional voltage translation. Its IOFF circuit actively disables output leakage during power-down, preventing backflow currents when VCC = 0V while inputs remain biased.

Input thresholds scale with VCC (e.g., VIH = 0.7×VCC at 4.5–5.5V), ensuring compatibility across 1.8V, 2.5V, 3.3V, and 5V domains. Propagation delay ranges from 0.5ns (typ.) at 5V to 6.5ns (max) at 1.8V, supporting timing-critical low-voltage logic interfacing.

FAQ

Can 74LVC1G06FW5-7 drive an I²C bus directly?

Yes - its open-drain output and 5.5V-tolerant input allow direct connection to I²C buses. It can replace standard I²C buffers when level translation between 1.8V/3.3V masters and 5V slaves is required. External pull-up resistors must be sized for total bus capacitance and desired rise time; maximum sink current (32mA) ensures robust low-level drive even under heavy loading.

What is the purpose of the NC pins on the X1-DFN1010-6 (Type B) package?

Pins 1 and 5 are designated No Connect and must not be bonded internally. They provide mechanical stability and routing flexibility on dense PCBs. Diodes Incorporated recommends leaving them floating or connecting to GND per their suggested pad layout - doing so improves thermal conduction and reduces EMI susceptibility without affecting logic operation.

How does IOFF protect the device during partial power-down?

When VCC drops near 0V, the IOFF circuit disables both input and output structures, limiting leakage current to ±200μA (max) even if inputs or outputs remain at 5.5V. This prevents reverse current flow into the powered-down VCC rail - protecting upstream regulators and avoiding unintended activation of downstream circuitry in battery-backed or hot-swap systems.

Is 74LVC1G06FW5-7 RoHS and halogen-free compliant?

Yes - it is fully RoHS 2 (2011/65/EU) compliant with no purposely added lead, and certified halogen- and antimony-free ("Green"): Br < 900ppm, Cl < 900ppm (Br+Cl < 1500ppm), Sb < 1000ppm. Compliance documentation and test reports are available through Diodes Incorporated's quality portal.
