SN74LVC1G14QDCKRQ1

Inverter Gates Overview

The SN74LVC1G14QDCKRQ1 is an automotive-grade single Schmitt-trigger inverter from Texas Instruments, designed for operation within a 1.65V to 5.5V supply voltage range. It features AEC-Q100 qualification and operates across a temperature range of -40°C to +125°C. The device provides Ioff support for partial power-down applications and includes latch-up protection exceeding 100mA per JESD 78 Class II standards.

Inverter Gates Feature Summary

• Schmitt-trigger input architecture ensures noise immunity through distinct positive and negative threshold levels
• Ioff circuitry disables outputs to prevent backflow current during partial power-down conditions
• Automotive grade certification (AEC-Q100) supports deployment in demanding vehicle environments

Inverter Gates Applications

• Signal conditioning for noisy digital interfaces
• Waveform shaping in automotive control modules
• Pulse generation circuits requiring hysteresis

Inverter Gates Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct package type and tape-and-reel specifications. Confirm that the specific revision matches project requirements, as manufacturing sites or assembly processes may change without altering the functional datasheet parameters.

Inverter Gates Selection Notes

Select this component when signal integrity requires noise filtering via hysteresis rather than simple inversion. Ensure the system voltage remains within the 1.65V to 5.5V operational window. Verify that the SC-70-5 package dimensions fit the PCB footprint constraints and that the thermal characteristics align with the expected ambient operating temperatures.

Inverter Gates Part Context

This device belongs to the SN74LVC1GxxQ family of single-gate logic ICs. It shares the LVC low-voltage CMOS technology platform but incorporates Schmitt-trigger inputs unlike standard inverters. The Q1 suffix denotes automotive qualification, distinguishing it from commercial variants while maintaining pin compatibility.

Inverter Gates FAQ

What is the primary function of the Schmitt trigger in this inverter?

It provides different input threshold levels for rising and falling edges, filtering out noise on slow-moving or noisy signals.

How does the Ioff feature benefit the circuit?

It automatically disables the output drivers when VCC is below a certain level, preventing damage from back-driving currents during partial power-down states.
