Product details

RoHS status — design constraint

This part is RoHS non-compliant. For designs requiring lead-free assembly or EU RoHS exemption compliance, this is a hard constraint — the part cannot be used in new products that must meet RoHS directives without an exemption. It remains suitable for repair, retrofit, and military/aerospace builds where leaded solder is still specified or exempted.

Because it is RoHS non-compliant, stock may be more common in non-RoHS inventory pools.

Frequently asked questions

Is CD74FCT646EN RoHS compliant?

No, the CD74FCT646EN is RoHS non-compliant. It uses lead-bearing solder and is not suitable for lead-free assembly unless an RoHS exemption applies.

What is the function of CD74FCT646EN?

It is an octal bus transceiver — eight bidirectional non-inverting transceiver channels with 3-state outputs, used for bidirectional data transfer between two 8-bit buses.
