Product details

RoHS status — what it means for your BOM

The 4021BDMQB is RoHS non-compliant, meaning it contains lead (Pb) in its termination finish or internal construction.

Bulk packaging — handling and assembly note

The Bulk package means the devices ship loose in a tube or tray, not on a tape-and-reel. This is standard for DIP or SOIC wide-body packages in low-to-medium volume. For hand-assembly or rework, Bulk is fine. If your pick-and-place line expects tape-and-reel, you will need to order the reel variant (e.g., 4021BDM) or transfer to a carrier tray — factor that into your kitting workflow.

Sourcing and supply posture

The 4021BDMQB is an Active part, so there is no last-time-buy or end-of-life risk. It is sourced through independent distribution and quoted to order against an RFQ.

Frequently asked questions

Where can I buy 4021BDMQB?

The 4021BDMQB is available to order through independent distribution. Submit an RFQ for current pricing and availability — stock is confirmed at quote time.

What is the 4021BDMQB shift register?

It is an 8-bit parallel-in/serial-out shift register that reads eight parallel inputs and shifts the data out serially. It is used for input expansion in microcontroller-based designs.

Is 4021BDMQB RoHS compliant?

No, the 4021BDMQB is RoHS non-compliant. It contains lead in its termination finish and is intended for applications where leaded solder is acceptable or required.
