LS7031 Overview
The LS7031 is a monolithic, ion implanted MOS, 6 decade up counter. The circuit includes latches, a multiplexer, leading zero blanking and BCD data outputs. CLOCK GENERATOR The clock for the six decade counter (digit positions 3-8) is formed from the internal ‘OR’ bination of B4/D2 and B8/D2 if LS7031 is used with external prescaling counters.
