This article will discuss the designing of TTL Voltage Level logic probe. The main components of this equipment or probe are a decoder and a common cathode seven segment display and an inverting logic gate. It will display the logic level of a TTL devices output appropriately on a common cathode seven segment display. A high voltage on a device output will be displayed as “H” character and a low level output voltage will be displayed as “L” character.
