74LVC1G17FX4-7

Overview

The 74LVC1G17FX4-7 is a single-input Schmitt-trigger buffer manufactured by Diodes Incorporated, housed in an X2-DFN1409-6 package. It operates within a supply voltage range of 1.65V to 5.5V and features standard push-pull outputs with ±24mA drive capability at 3.3V. The device includes IOFF circuitry for partial power-down applications, preventing damaging backflow currents. Inputs are tolerant to 5.5V, facilitating mixed-voltage environments. It provides ESD protection exceeding 2000V (HBM) and 1000V (CDM), with latch-up resistance exceeding 100mA.

Feature Summary

• Schmitt-trigger input action ensures noise immunity and clean signal transitions.
• IOFF circuitry supports partial power-down mode operation to prevent backflow.
• Inputs accept up to 5.5V, enabling compatibility in mixed-voltage systems.
• High ESD protection ratings exceed 2000V Human Body Model standards.

Applications

• Voltage level shifting between different logic families
• General purpose logic buffering
• Power down signal isolation

Procurement Notes

Verify the FX4 suffix corresponds to the X2-DFN1409-6 package configuration before ordering. Confirm that the specific revision of the datasheet matches the production lot requirements. Ensure design compliance with the recommended pad layout provided in the manufacturer's documentation to maintain thermal and electrical performance standards.

Selection Notes

Select this component when a single-channel non-inverting buffer with hysteresis is required. The wide operating voltage range accommodates various system power rails. The compact chip-scale package is suitable for space-constrained PCB layouts. Verify that the output drive current meets the load requirements of the destination circuitry.

Part Context

This part belongs to the 74LVC1G17 series of single Schmitt-trigger buffers from Diodes Incorporated. The series offers multiple package options including SOT25, SOT353, and various DFN configurations. All variants share identical electrical characteristics and functionality, differing only in physical footprint and pin assignment.

Replacement Considerations

Other packages within the same 74LVC1G17 family, such as 74LVC1G17FZ4-7 or 74LVC1G17FW4-7, offer equivalent electrical performance. Substitution requires verification of mechanical fit and pinout compatibility with the existing board design.

FAQ

What is the function of the IOFF feature?

The IOFF circuitry disables the output when the device is powered down, preventing damaging current backflow into the supply lines.

Is the 74LVC1G17FX4-7 inverting or non-inverting?

It is a non-inverting buffer, meaning the output state follows the input state directly.
