10509/BEBJC – MOTOROLA

The 10509/BEBJC, manufactured by Motorola, is a high-speed emitter-coupled logic (ECL) gate integrated circuit. It is fabricated using a bipolar process optimized for sub-nanosecond propagation delays, characteristic of ECL technology. The device is housed in a 16-pin ceramic dual in-line package (CDIP16), chosen for its hermetic seal and ability to withstand elevated operating temperatures. The 10509 implements a specific logic function, likely a dual OR/NOR gate or similar combination, consistent with standard ECL gate configurations. External termination resistors are required for proper operation due to the low impedance levels inherent in ECL circuitry. The device operates from a negative supply voltage, typically -5.2V, and is designed for applications requiring high-frequency signal processing and minimal timing skew.
