DC 5V Priority Encoder Module
Description:
The circuit is composed of 74HC147 priority encoding chip as the core, the short-circuit cap can visually see the input situation, and the 4 light-emitting diodes can intuitively display the encoding result.:The priority encoder is when there are signals at multiple input terminals at the same time, the circuit only encodes the input signal with the highest priority among them. This kit consists of 8421??BCD code priority encoder composed of 74LS147. The 74LS147 priority encoder has 9 input terminals and 4 output terminals. If 0ne of the input terminals is 0, it means that a certain decimal number is input. When all 9 input terminals are 1, it means that the input is a decimal number 0. The 4 output terminals reflect the BCD code output of the input decimal number. The input and output terminals of the 74LS147 priority encoder are both active at low level, that is, when a certain input terminal is at low level 0, the four output terminals will output the corresponding 8421BCD code at low level 0, and the corresponding luminous Diodes LED1-4 will light up for indication. When the 9 inputs are all 1, the 4 outputs are all 1, representing the 8421BCD coded output of the input decimal number 0. The S1-59 in the kit is welded by pin headers, and the switch is closed when the short-circuit cap is put on.
