Real time 5-decade counter

DESCRIPTION The HEF4534B is a 5-decade ripple counter. The binary outputs of the decade counters are time-multiplexed by an internal scanner on four BCD outputs (O0 to O3). The selected decade is indicated by a logic HIGH on the appropriate digit select output (OS0: units, 1; OS1: tens, 10;
