Product details

What this dual 4:1 mux does on the board

The 5.2 mA output drive (sink and source) is enough to swing CMOS inputs or a single LED, but don't plan on driving a relay coil or a long backplane trace directly.

Package and compliance — the gotcha

The RoHS non-compliant flag means the leads contain lead. If your assembly line is RoHS-mandated (EU, California, medical), you will need an exemption or a lead-free alternative. For military or high-rel work where tin whiskers are a concern, the leaded finish is actually preferred.

Frequently asked questions

Is MM74HC153J RoHS compliant?

No, it is marked RoHS non-compliant. The leads contain lead, which is typical for military-temp through-hole parts. Not suitable for RoHS-mandated assemblies without an exemption.

Is MM74HC153J a replacement for 74HC153?

The MM74HC153J is a specific variant of the 74HC153 dual 4:1 multiplexer. The 'J' suffix typically denotes a through-hole DIP package and the military temperature range. It is functionally the same as a standard 74HC153 but with the extended temperature grade.

When sourcing MM74HC153J, what is the closest functional second-source?

The SN74LS348N is a different device — a priority encoder, not a multiplexer — so it is not a functional second-source. For a dual 4:1 mux in the 74HC family, look at the 74HC153 from other manufacturers (TI, NXP) in a DIP-16 package. No exact cross-reference is in the record.
