This is a 4 bit presetable CMOS ring counter, CD4029. This counter has ?UP Count facility, by switch selection
?DOWN Count facility by switch selection
?Preset a count in the range of 0000 to 1001 in case of DECIMAL count or from 0000 to 1111 in case of BINARY count. This is achieved by setting the 4bit PRESET state switches to either at 0 or at 1 state.
?Can be used as either a Straight Binary counter or DECIMAL counter. Using the above counter any mode of operation can be set. A logic-1 output of this counter is used as gate trigger required for the SCR to go into active state. This in turn will act as a solid switch. A 230V AC operated Lamp load is used to display the state of the counter. In addition 4 bit LEDs will also display the status of this counter. |
