MC14569B Programmable Divide-By-N Dual 4-Bit Binary/BCD Down Counter
The MC14569B is a programmable divide–by–N dual 4–bit binary or BCD down counter constructed with MOS P–channel and N–channel enhancement mode devices (complementary MOS) in a monolithic structure. This device has been designed for use with the MC14568B phase comparator/counter in frequency synthesizers, phase–locked loops, and other frequency division applications requiring low power dissipation and/or high noise immunity. • Speed–up Circuitry for Zero Detection • Each 4–Bit Counter Can Divide Independently in BCD or Binary Mode • Can be Cascaded With MC14568B, MC14522B or MC14526B for Frequency Synthesizer Applications • All Outputs are Buffered • Schmitt Triggered Clock Conditioning MAXIMUM RATINGS* (Voltages Referenced to VSS)
