Device identity and function
The Texas Instruments 100102FCQL is an OR/NOR gate from the 100K series of emitter-coupled logic (ECL) devices, a family known for its high-speed switching performance in digital systems. This part sits in the Logic ICs category and is supplied in a Bulk package format, which is typical for through-hole or larger surface-mount devices that are ordered in engineering quantities or for manual assembly.
Cross-reference and compatibility
The 100102FCQL has peer parts including the JM38510/65103BCA, 9005PC, and SN74F30NS, all in Bulk packaging. These are functionally similar OR/NOR gates from different logic families (military-screened 38510, standard 9000-series, and 74F-series), but the 100K ECL family operates at a different voltage and logic swing than TTL or CMOS-based peers, so a direct drop-in replacement without board-level changes is unlikely.
