No end-of-life notice or last-time-buy window has been announced, so this part remains available for new designs and replacement orders without immediate obsolescence risk. The part is RoHS non-compliant, which is typical for MIL-screened hermetic ceramic packages that use lead-based solder terminals. If your BOM requires RoHS compliance, this part will not pass the restriction — plan for a waiver or an alternative finish. For defence and aerospace builds, the non-compliant status is often acceptable or even required for solder-joint reliability under thermal cycling. ## Package and handling — Bulk form For automated pick-and-place lines, this means manual tube feeding or tray loading; verify your feeder compatibility for volume.","metaTitle":"DM54LS169W/883 Binary Counter, LS Series, Active","metaDescription":"DM54LS169W/883 is a 4-bit synchronous binary counter from the LS series.
