SN74HCT14QPWRG4Q1

Inverter Gates Overview

The SN74HCT14QPWRG4Q1 is an automotive-grade hex Schmitt-trigger inverter manufactured by Texas Instruments. It belongs to the HCT logic series and utilizes CMOS technology. The device operates within a supply voltage range of 4.5 V to 5.5 V. It features six independent inverting channels with Schmitt-trigger inputs for noise immunity. The component is housed in a 14-pin TSSOP package and supports surface-mount installation. It is qualified under AEC-Q100 standards and functions reliably across an extended temperature range from -40°C to +125°C.

Inverter Gates Feature Summary

• Six independent inverting channels integrated into a single package
• Schmitt-trigger input architecture provides enhanced noise filtering and signal conditioning
• Automotive qualification ensures reliability for demanding vehicle environments
• CMOS construction enables low static power consumption

Inverter Gates Applications

Inverter Gates Procurement Notes

Verify the complete part number including suffixes to ensure correct automotive qualification and packaging configuration. Confirm that the specific revision matches design requirements. Check RoHS compliance status as indicated in official documentation. Ensure ESD handling procedures are followed during assembly. Validate thermal performance against system constraints before final integration.

Inverter Gates Selection Notes

Select this component when interfacing 5V logic systems with noisy environments requiring hysteresis. The HCT series ensures compatibility with standard TTL logic levels while maintaining CMOS advantages. Consider the TSSOP package dimensions for PCB layout constraints. Evaluate the operating temperature range against environmental conditions. Verify supply voltage stability within the specified 4.5V to 5.5V window.

Inverter Gates Part Context

This device is part of Texas Instruments' broader portfolio of automotive-qualified logic ICs designed for robust performance in vehicles. It complements other inverters, buffers, and drivers within the SN74x family. The Q1 suffix denotes automotive grade qualification, distinguishing it from commercial variants. It serves as a critical interface component between sensors, microcontrollers, and actuators in modern electronic control units.

Inverter Gates Replacement Considerations

SN74HC14QPWRG4Q1 offers similar functionality but operates over a wider voltage range (2V–6V) with HC speed characteristics instead of HCT. SN74AHCT14QPWRG4Q1 provides faster switching speeds while maintaining HCT voltage compatibility. Direct pin-to-pin substitution requires verification of propagation delay and drive current specifications against application needs.
