The MC145158–2 has a fully programmable 14–bit reference counter, as well
as fully programmable ÷ N and ÷ A counters. The counters are programmed
serially through a common data input and latched into the appropriate counter
latch, according to the last data bit (control bit) entered.
The MC145158–2 is an improved–performance drop–in replacement for the
MC145158–1. Power consumption has decreased and ESD and latch–up
performance have improved.
