Two of the pins should be connected to the supply voltage and ground and the other pins are used as logic inputs and outputs, sometimes a pin can lack connection to the inside of the chip, it is then called NC (no Connection). For orienting the capsules they have an outlet on the short side, and there can also be a "dot" to mark the pin number 1. The digital components have capsules with 14 or 16 pins. Anyone interested can download it now.ħ4HCT00.fzpz 74HCT02.fzpz 74HCT08.fzpz 74HCT32.fzpz 74HCT86.fzpz (This program will be used in the course IE1206 but is not needed for this course). Working with circuits on the breadboard is therefore the natural working method for project work and theses for school and hobby activities.įritzing Is the name of a software for documenting breadboard connections, and generate circuit diagrams, and possibly manufacture printed circuit boards. Breadboard are now also used with very complex circuits - then mounted on Breakout Board (a breakout board has the same pin spacing DIL) circuits. These old circuits, are however unbeatable for experiments with simple connections on the breadboard. This is today considered to be pure spare parts, and development has changed to completely different package types for surface mounting. Chips and BreadboardĪt the labs, we use digital circuits from the so-called 74-series of capsules of the DIL type (Dual In Line) for hole PCB assembly.
