The MC145152–2 is programmed by sixteen parallel inputs for the N and A
counters and three input lines for the R counter. The device features consist of
a reference oscillator, selectable–reference divider, two–output phase detector,
10–bit programmable divide–by–N counter, and 6–bit programmable ÷ A
counter.
The MC145152–2 is an improved–performance drop–in replacement for the
MC145152–1. Power consumption has decreased and ESD and latch–up
performance have improved.
