CD40192b Presettable BCD Up/Down Counter and the CD40193B Presettable Binary Up/Down Counter each consist of 4 synchronously clocked, gated \"D\" type flip-flops connected as a counter. The inputs consist of 4 individual jam lines, a PRESET\\ ENABLE\\ control, individual CLOCK UP and CLOCK DOWN sign • Individual clock lines for counting up or counting down\n• Asynchronous reset and preset capability\n• 5-V, 10-V, and 15-V parametric ratings\n• 100% tested for quiescent current at 20 V\n• Noise margin (full package-temperature range) =         1 V at VDD = 5 V         2 V at VDD = 10 V     ;
