Overview
The MC100EL12D, produced by onsemi, is a 5.0 V ECL (Emitter-Coupled Logic) low impedance driver. This device is part of the 100 Series and is designed for high-drive applications, particularly those requiring fast propagation delays and high AC performance. It is functionally equivalent to the E112 device but offers superior performance characteristics. The MC100EL12D features dual OR/NOR outputs, making it ideal for applications such as memory addressing.
