ECL100K line driver/receiver — what this part is
The 100114FC is a line driver/receiver from the ECL100K logic family, designed for high-speed differential signaling in backplane or cable interconnect applications where propagation delay and edge rates are critical. The ECL100K series is known for sub-nanosecond switching and complementary outputs, making this part suitable for clock distribution, data transmission, and signal conditioning in telecom, instrumentation, and high-reliability systems. It is, typically loose units rather than tape and reel, which suits prototype runs or small-batch production.
Active lifecycle and RoHS constraint
However, it is marked RoHS non-compliant, so designs requiring lead-free solder or EU RoHS exemption documentation must verify compatibility. For legacy or military/aerospace BOMs where tin-lead assembly is specified, this part is a direct fit without the need for waiver paperwork.
Sourcing this part — what to expect
Because the part is active and RoHS non-compliant, buyers should expect it to be available from surplus or authorized channels that handle legacy logic families.
