These macros fill this gap.Įach of these macros must be combined with an Interactive Switch in order to function. While the "Interactive Inputs" in Digital Works can be used to control inputs as "high" or "low," sometimes you want to directly simulate a real switch that is "open" or "closed." Digital Works does supply an "Interactive Switch" (different from an "Interactive Input"), but it doesn't have parts like resistors, which nearly always accompany such switches.
JK Flip Flop like half of a 74112 (active-low PRESET and CLEAR, unlike the JK-FF on the Digital Works Tool Bar).D Flip Flop like half of a 7474 (active-low PRESET and CLEAR, unlike the D-FF on the Digital Works Tool Bar).74138 3-bit decoder with three enable inputs.7-segment display decoder like a 7447 chip (layed out to be placed directly below a Digital Works 7-segment display).Generally, Digital Works inputs float LOW, although even that is not reliable.
WARNING: Digital Works does not simulate the "inputs float HIGH" behavior of TTL chips. By using the "Embed Macro" button on the tool bar, you can put these devices in circuits that you are creating. The following links can be used to download *.dwm files, which are macros for Digital Works. CSCI 230: Digital Electronics Digital Works Macros
