Resistor network, 9 pins.
What is Resistor Networks?
Resistor networks are combined by several resistors with the same value, they are use one of the same common pin are connected together as a common pin. The remaining pin leads to normal. So if an exclusion is constituted by the n resistors, then it will have n 1 only pin, in general, that is the left-most common pin. General exclusion on a color point marked out. The resistor network is generally used in digital circuits, such as: as a parallel port on the pull-up or pull-down resistor with. Using resistor network is more convenient to use a number of fixed resistor.
Difference between type a and b.
- The pin of A type resistor network is always odd. Its left end with a common terminal (white dots), said common exclusion 4,7,8 resistor, so the number of pins from 5 or 8 or 9.
- The pin of B type resistor network is always even. It does not have a public side, the common exclusion of four resistance, so pin 8.
The exclusion of resistance read method is as follows: “103”: 10 kΩ, “510”, said: 51Ω. And so on.
