What this part is and where it fits
The JM38510/30105BCA is a dual JK flip-flop with preset, built for edge-triggered toggling and synchronous counting in TTL logic systems. Each flip-flop has independent J, K, clock, and preset inputs, with complementary Q and Q̅ outputs.
Bulk package — what it means on the bench
This part ships in bulk — loose parts, no tape or reel. That is fine for manual insertion on a rework bench or for low-volume builds where you are populating boards by hand.
Lifecycle and sourcing reality
The JM38510/30105BCA is listed as active in production — no end-of-life notice, no last-time-buy window to chase. That is the good news for a BOM line that needs a JAN-qualified flip-flop. The part is sourced through independent distribution; we can quote it against an RFQ and confirm current availability and pricing at the time of your inquiry. For volume or long-term contracts, the active status means you are not forced into a broker scramble — but do verify lead times on your specific quantity, as JAN-screened parts can have longer factory cycles than commercial equivalents.
