MC145157_2数据手册恩XP中文资料规格书

描述 Description

Overview 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.
