74LVC2G17W6-7

Overview

The 74LVC2G17W6-7 is a dual Schmitt trigger buffer manufactured by Diodes Incorporated, designed for operation with a power supply range of 1.65V to 5.5V. It features standard push-pull outputs and inputs tolerant to 5.5V, enabling use in mixed-voltage environments. The device supports partial power-down applications via IOFF circuitry, which disables outputs to prevent damaging current backflow when powered down. It operates within an ambient temperature range of -40°C to +125°C.

Feature Summary

• Dual Schmitt trigger buffers with standard push-pull outputs
• Inputs accept up to 5.5V for mixed-voltage compatibility
• IOFF circuitry prevents damaging current backflow during partial power-down
• ESD protection exceeds 2000V Human Body Model and 1000V Charged Device Model

Applications

• Voltage level shifting
• General-purpose logics
• Power down signal isolations

Procurement Notes

Verify the specific package marking code Z6 on SOT26 components to confirm authenticity against Diodes Incorporated standards. Ensure that the ordering suffix matches the required tape and reel quantity of 3000 units. Confirm compliance with RoHS directives and lead-free requirements as specified in the manufacturer's documentation before finalizing procurement orders.

Selection Notes

Select this component when dual non-inverting buffering with hysteresis is required in low-power CMOS designs. The SOT26 package provides a compact footprint suitable for space-constrained PCB layouts. Consider the wide operating voltage range and high ESD tolerance for robust performance in portable electronics and communication networks.

Part Context

This part belongs to the 74LVC logic family, characterized by low voltage CMOS technology. It is functionally compatible with other 74LVC series devices but offers specific Schmitt trigger input characteristics. The W6 suffix designates the SOT26 surface-mount package, distinguishing it from other variants like DW (SOT363) or DFN packages within the same logical family.

Replacement Considerations

Direct pin-compatible replacements include the 74LVC2G17DW-7 (SOT363 package). Other package options such as FW4, FX4, and FZ4 offer alternative form factors while maintaining identical electrical functionality. Verify thermal resistance and physical dimensions when substituting between different package types.

FAQ

How does the IOFF feature benefit partial power-down applications?

The IOFF circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down while the system remains active.

What is the maximum input voltage tolerance for this device?

The inputs are tolerant to 5.5V, allowing the device to be used safely in mixed-voltage environments where higher voltage signals may be present.
