Description

The MC14029B Binary/Decade up/down counter is constructed with MOS Pchannel and Nchannel enhancement mode devices in a single monolithic structure. The counter consists of type D flipflop stages with a gating structure to provide toggle flipflop capability.The counter MC14029B can be used in either Binary or BCD operation. This complementary MOS counter finds primary use in up/down and difference counting and frequency synthesizer applications where low power dissipation and/or high noise immunity is desired. MC14029B is also useful in A/D and D/A conversion and for magnitude and sign generation.
