Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt to ensure component authenticity and traceability. Confirm that the physical package matches the specified 20-pin DIP form factor. Check for any manufacturing change notices (PCN) related to this discontinued or limited-stock item. Ensure storage conditions comply with moisture sensitivity level requirements before soldering.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring multiple buffered outputs driven by a single control signal. The VHC series offers superior switching speeds compared to standard HC logic while maintaining CMOS power efficiency. Consider the 3.6 V maximum rating when interfacing with higher voltage domains to prevent damage. Evaluate the parasitic capacitance of the PCB traces if operating near the upper frequency limits of the device.
