Input status indication circuit diagram
Source: InternetPublisher:傻阿乐 Keywords: Circuit diagram digital tube diode Updated: 2021/05/07
This circuit monitors the data input of one bit and displays "H" or "L" on the 7-segment digital tube according to its status. This circuit uses two 7437 inverters and a DL-704 common cathode digital tube. The diode symbol represents a segment of the digital tube (segment A is not needed when displaying H or L). The power connection method of the 7437 inverter is 14 connected to +5V and 7 connected to ground.
