Overview
The SN74AHCT14RGYRG4 is an automotive catalog hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and supports a load capacitance of 50 pF. The device features six independent inverting channels with Schmitt-trigger inputs for noise immunity. It is housed in a 14-VQFN package (3.5x3.5 mm) and is rated for an operating temperature range from -40°C to +125°C. The component complies with RoHS standards and is lead-free.
Feature Summary
- Automotive-grade reliability for harsh environments
- Schmitt-trigger inputs provide noise filtering
- Wide supply voltage compatibility
- Compact surface-mount packaging
Applications
- Automotive signal conditioning circuits
- Noise-immune digital input buffering
- Waveform shaping in high-temperature systems
Procurement Notes
Verify the specific suffix RGYRG4 against official Texas Instruments documentation to confirm the exact package type, tape-and-reel specifications, and automotive qualification status. Ensure the source provides valid traceability for automotive catalog components. Cross-reference the manufacturer part number with current datasheets to confirm availability and compliance with RoHS directives before finalizing procurement orders.
Selection Notes
Select this component when automotive-grade durability and noise immunity are required for inverting logic signals. The Schmitt-trigger functionality is critical for applications involving slow-rise or noisy input waveforms. Verify that the 14-VQFN package dimensions fit the PCB layout constraints and that the operating temperature range meets the environmental requirements of the target system.
Part Context
This part belongs to the SN74AHCT14 family of hex Schmitt-trigger inverters. It shares functional similarities with other automotive-qualified logic devices but is distinguished by its specific VQFN packaging and AEC-Q100 qualification. It serves as a robust solution for replacing standard commercial logic in demanding automotive electronic control units and sensor interfaces.
Replacement Considerations
Check for direct substitutes such as SN74AHCT14RGYR if the G4 suffix indicates a specific manufacturing variant. Ensure any replacement maintains the same VQFN footprint and automotive temperature rating. Verify pinout compatibility and electrical characteristics like propagation delay and output drive strength.
