CD4093BE DIP-setech DataSheet

CMOS Presettable Binary Up/Down Counter


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 signals and a master RESET. Four buffered Q signal outputs as well as CARRY and BORROW outputs for multiple-stage counting schemes are provided


  • Individual clock lines for counting up or counting down
  • Synchronous high-speed carry and borrow propagation delays for cascading
  • Asynchronous reset and preset capability
  • Medium-speed operation–fCL = 8MHz (typ.) @ 10 V
  • 5-V, 10-V, and 15-V parametric ratings
  • Standardized, symmetrical output characteristics
  • 100% tested for quiescent current at 20 V
  • Maximum input current of 1 µA at 18 V over full package-temperature range; 100 nA at 18 V and 25°C
  • Noise margin (full package-temperature range) =
    1 V at VDD = 5 V
    2 V at VDD = 10 V
    2.5 V at VDD = 15 V
  • Meets all requirements of JEDEC Tentative Standard No. 13B, "Standard Specifications for Description of ’B’ Series CMOS Devices"
  • Up/down difference counting
  • Multistage ripple counting
  • Synchronous frequency dividers
  • A/D and D/A conversion
  • Programmable binary or BCD counting
