Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the G4 suffix, which indicates lead-free and RoHS compliance status as defined by Texas Instruments. Confirm the package type is TSSOP-20 and ensure the automotive qualification (Q100) matches your specific environmental requirements. Cross-reference the datasheet revision to ensure parameter consistency with your design specifications before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when HCT input compatibility is required alongside AHC speed performance in automotive environments. It serves as a suitable replacement for standard 74HCT244 variants where higher switching speeds are needed without sacrificing noise immunity. Ensure the power supply voltage remains strictly within the 4.5 V to 5.5 V range to maintain specified timing parameters and avoid excessive power consumption during operation.

Buffers, Drivers, Receivers, Transceivers Part Context
