Resistor Networks, Arrays

741C083334JP is a resistor network and array manufactured by Yageo. It is an 8 pin chip resistor network with a built-in protection circuit. The device allows resistors to be paired and connected in a matrix. The main purpose of the product is to reduce the number of individual resistors in a given scheme, thus simplifying a circuit design.

Application Field

741C083334JP is used in audio and video equipment, as well as microprocessors and other integrated circuits. Generally, it’s used in applications requiring a resistor network to split signals, reduce parts count, or provide protection from signals in excess of the desired range.In audio amplifiers, for example, this component is used to reduce the number of resistors needed in order to create a desired power output. In video equipment, it is used to ensure that the DC offset voltage remains within the acceptable levels. Finally, in microprocessors, it is used to provide input buffers and prevent noise on the signal lines.

Working Principle

The 741C083334JP resistor network contains a unique configuration that contains levels of resistance, isolation, and protection circuits. The network is designed to provide a consistent amount of resistance throughout the chip, while also providing impedance matching.The resistor network is composed of four pairs of resistors, each offering a different resistance and impedance level. Each pair is isolated from the other pairs with an isolation circuit. Moreover, the pairs are each connected in series with a common junction point in order to provide a higher resistance in the overall circuit. Additionally, the device contains a protection circuit which limits the excess current to prevent damage to the components. This circuit checks for an excessive voltage or current, and then acts to reduce the excess amount of signal. The chip also contains a thermal protection circuit which acts to prevent the chip from over-heating.
