74LV17APWJ

Overview

The Nexperia 74LV17APWJ is a hex buffer with Schmitt-trigger inputs, designed to transform slowly changing input signals into sharply defined, jitter-free output signals. It operates within a supply voltage range of 2.0 V to 5.5 V and supports mixed-mode voltage operation on all ports. The device features IOFF circuitry for partial power-down applications, preventing damaging backflow current. It is specified from -40 °C to +125 °C and housed in a TSSOP14 (SOT402-1) package.

Feature Summary

• Schmitt-trigger inputs provide noise immunity and signal conditioning for slow-rise/fall times.
• IOFF circuitry enables safe partial power-down mode by disabling outputs.
• Overvoltage tolerant inputs support interfacing in mixed-voltage environments.

Applications

• Signal buffering and level translation in mixed-voltage systems
• Clock distribution networks requiring jitter-free signal integrity
• Interface circuits connecting different logic families

Procurement Notes

Verify the ordering suffix 'J' corresponds to the specific tape-and-reel packaging configuration required for your assembly line. Confirm that the TSSOP14 body width matches your PCB footprint design rules. Ensure the selected temperature grade (-40 °C to +125 °C) aligns with your environmental operating conditions before finalizing procurement.

Selection Notes

Select this component when Schmitt-trigger action is necessary to eliminate noise on slow-moving signals. The wide supply voltage range allows compatibility with both 3.3 V and 5 V logic systems. Consider the IOFF feature if the system requires safe isolation during power-down states to prevent bus contention or back-powering issues.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices. It functions as a hex non-inverting buffer, distinct from NAND or flip-flop variants in the same family. The TSSOP14 package provides a compact surface-mount solution suitable for high-density PCB layouts while maintaining thermal performance across industrial temperature ranges.

Replacement Considerations

Direct pin-compatible substitutes include other 74LV17A variants from Nexperia with different package options such as SO14 or SSOP14. Verify that any replacement maintains the same Schmitt-trigger input characteristics and IOFF functionality to ensure circuit compatibility without redesign.

FAQ

How does the IOFF circuitry function in this device?

The IOFF circuitry disables the outputs when the device is powered down (VCC = 0 V), preventing potentially damaging backflow current through the device and ensuring safe operation in partial power-down applications.

What is the primary benefit of Schmitt-trigger inputs in this buffer?

Schmitt-trigger inputs transform slowly changing input signals into sharply defined, jitter-free output signals, providing improved noise immunity compared to standard logic buffers.
