Procurement Notes

Verify the specific suffix 'G4' corresponds to lead-free and RoHS compliance status as defined by Texas Instruments documentation. Confirm the package designation matches the required SOT-353 footprint for PCB layout. Ensure the ordering part number aligns exactly with the intended revision and packaging format before finalizing procurement orders.

Selection Notes

Select this component when a compact solution for multiple buffered channels is required. The SOT-353 package offers a small form factor suitable for space-constrained designs. Verify that the input voltage levels are compatible with the chosen supply voltage to prevent damage or undefined states during operation.

Part Context

This component belongs to the CD74HC40xx series of high-speed CMOS logic devices. The series provides standard buffer functions with enhanced speed compared to legacy counterparts. The 'CD' prefix indicates commercial grade temperature range availability, while 'HC' denotes High-speed CMOS technology optimized for modern digital systems.

Replacement Considerations

Compatible substitutes include CD74HC4049PW and CD74HC4049PWR. Verify pinout compatibility and package dimensions before substitution. Ensure electrical characteristics such as propagation delay and drive current meet the original design requirements.
