The MC145151–2 is programmed by 14 parallel–input data lines for the
N counter and three input lines for the R counter. The device features consist of
a reference oscillator, selectable–reference divider, digital–phase detector, and
14–bit programmable divide–by–N counter.
The MC145151–2 is an improved–performance drop–in replacement for the
MC145151–1. The power consumption has decreased and ESD and latch–up
performance have improved.
