SEMICONDUCTOR TECHNICAL DATA
The MC10H115 is a quad differential amplifier designed for use in sensing
differential signals over long lines. This 10H part is a functional/ pinout
duplication of the standard MECL 10K family part, with 100% improvement in
counting frequency and no increase in power–supply current.
