1. The gate   1.1 AND gate   And gate is two inputs and one output, when both inputs are 1, the output will be 1, otherwise the output will be 0. The underlying principle of the gate is explained by relays as follows:     In the case of an energized coil, there will be a magnetic effect. In the figure above we can see that if the two coils are energized, they will each suck down the switch above them, thus making the switch closed, which will then eventually lead to the bulb being energized.   We can see that there is a power supply connected to the bulb, and there are two switches on this circuit, which are controlled by the other two power supplies, so three power supplies are used in the whole circuit.     After simplifying the circuit, it looks like this above. As you can see, the light bulb should have the power to ignore, leaving only two switching power supplies.   1.2 Or-gate   OR-gate also has two inputs and one output. If at least one of the two inputs is 1, then the output i

What  is date code label? 1 ．🤔 What is the LOT CODE ？ LOT CODE is also called LOT No., LOT No. is the abbreviation of lot number, which means "lot number". In order to trace and review the production history of the batch of components, so each batch of products have the corresponding production number.   The production lot number is the number of components in the same batch. It is a set of numbers or letters plus numbers used to identify the "batch". In general, according to the batch number can track the production of the product (production date, quality level, factory time, origin, etc.).  Now most companies are gradually unifying the production date and production lot number of components. The lot number and D/C form given by different original manufacturers are different. 2 ．🚩 Device package marking     Figure 6-1 shows the Xilinx Logo; Family Brand Logo; the first line is the product model silkscreen; the second line includes the package,bare chip version,
