MC145159-1

The MC145159-1 has a programmable 14-bit reference counter, as well as programmable divide-by-N/divide-by-A counters.The counters MC145159-1 are programmed serially through a common data input and latched into the appropriate counter latch,according to the last data bit(control bit)entered.

Features of the MC145159-1 are:(1)low power consumption through use of CMOS technology; (2)3.0 V to 9.0 V supply range; (3)on- or off-chip reference oscillator operaiton; (4)compatible with the serial peripheral interface(SPI) on CMOS MCUs; (5)high-gain ananlog phase detector; (6)general purpose applications.

The absolute maximum ratings of the MC145159-1 can be summarized as:(1): DC supply voltage(VDD) is -0.5 V to +10.0 V; (2): input or output voltage(DC or transient)(Vin,Vout) is -0.5 V to VDD+0.5 V; (3): input or output current(DC or trasient),per pin(Iin, Iout) are ±10 mA; (4): supply current, VDD or VSS oins(IDD,ISS) are ±30 mA; (5): power dissipation, per package(PD) is 500 mW; (6): storage temperature(Tstg) is -65 to +120; (7): lead temperature(8-second soldering)(TL) is 260.
