Product details

RoHS non-compliance — what it means for your BOM

This part is RoHS non-compliant, which means it contains lead (Pb) in the solder finish or die-attach material. For new designs bound for EU or California markets, this is a showstopper unless the application falls under an exemption (e.g., high-reliability aerospace, medical implant, or military equipment). For legacy repair or maintenance of existing non-RoHS boards, it is often the exact match needed to maintain original signal timing and reliability. Verify your compliance path before specifying.

Package and handling note

Bulk packaging (tubes) is the standard delivery format for through-hole DIP logic. The SN74S22N is not available in tape-and-reel, so automated pick-and-place lines will require tube feeders or manual handling. For high-volume assembly, plan for tube-to-tube transfer or consider a surface-mount alternative like the SN74F00DR if the board layout allows. The through-hole package offers robust mechanical retention in high-vibration environments but consumes more board area than SMT equivalents.

Frequently asked questions

What is the difference between SN74S22N and SN74LS22N?

The SN74S22N uses Schottky-clamped TTL (74S family), while the SN74LS22N uses Low-Power Schottky (74LS family). The S variant offers higher switching speed at the cost of higher power consumption; the LS variant draws less current but has slower propagation delay. Pin-for-pin compatible, but timing and power budgets differ — check your design's margin before substituting.

Is SN74S22N RoHS compliant?

No, the SN74S22N is RoHS non-compliant. It contains lead and is not suitable for new designs requiring RoHS exemption-free compliance unless a specific exemption applies.
