The 54LS112FM is a J-K flip-flop from Texas Instruments, listed as active in production. For a BOM that calls out this order code, the part is still in the manufacturer's current portfolio — no end-of-life notice or last-time-buy window has been issued. It ships in Bulk packaging, which is the standard tube or tray format for through-hole or surface-mount logic ICs in prototype and low-to-medium volume runs. The RoHS compliance status is non-compliant, so this part is not suitable for assemblies requiring RoHS exemption-free soldering processes.
Fit and compliance flags for the procurement desk
The RoHS non-compliance is the main sourcing constraint: if your BOM requires RoHS compliance, you will need to qualify an alternative logic family or accept the non-compliant status for legacy maintenance builds.
