Abstract: rs8629 increase the range to 50MHz a 74LS90 decade counter (RS stock no. 307-610) may be used or to increase the , 74LS90 must be a digital circuit. If decimal point position correction is required see following section. Note: The output from the 74LS90 comes from the QC rather than QD to obtain an input duty cycle

Abstract: â'¢ Decade Counters The H D 74LS90 contain* four mester-tiave flip-flop* and addi­ tional sating to provide a divide-by-two counter and threestag* binary counter for divide-by-five. T h is device hat a gated zero reset and alto hat gated set-to-nine input* for use in BCD nine's complement applications. T o use this maximum count length of this counter the B input is connected to the Q A out­ put. The input count pulses are applied to input A and the outputs are descrived in the appropriate -
