Procurement Notes

Verify the specific suffix 'E' indicates the through-hole DIP package variant distinct from surface-mount versions. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the ordering part number matches the required pin count and package style for your PCB design constraints.

Selection Notes

Select this component when designing circuits that require eight-channel signal inversion with tri-state capability. It is appropriate for applications needing compatibility with standard TTL logic levels while benefiting from CMOS characteristics. Consider the 20-pin DIP form factor if prototyping or utilizing through-hole assembly processes.

Part Context

This device belongs to the CD74HCT series of high-speed CMOS logic products manufactured by Texas Instruments. The HCT series is designed to be compatible with standard TTL inputs while offering improved performance over older LS logic families. The octal buffer architecture allows for efficient management of multiple data lines simultaneously.
