The MC145157–2 has a fully programmable 14–bit reference counter, as well
as a fully programmable ÷ N counter. 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 MC145157–2 is an improved–performance drop–in replacement for the
MC145157–1. Power consumption has decreased and ESD and latch–up
performance have improved.
• Operating Temperature Range: – 40 to 85°C
• Low Power Consumption Through Use of CMOS Technology
