Logic-signal switches, multiplexers, and decoders are components from the family of logic digital circuits. While they all have distinct functions, they all operate under similar principles. 728985JG is a selection of logic chips developed by Microchip Technology, Inc. and is used within a range of applications. In this article, the application field and working principle of 728985JG will be discussed in detail.

Applications

The 728985JG is mainly used as logic signal switches and decoders, providing a cost effective solution with a mix of both logic signal switching and signal decoding capabilities. Microchip Technology has labeled 728985JG as ideal for applications involving (Active) Serial Peripheral Interface (SPI), (Active) Universal Serial Bus (USB) Bridgeless Interface, LCD Interface and Non-volatile Memory Interface, among others. 928985JG is best fit for complicated data management tasks in a system that involves multiple communication channels.

In addition to logic signal switching, due to its many pins, 728985JG can serve as a multiplexer, enabling external circuits to something arbitrary from multiple sources. A multiplexer increases the total number of possible outputs of the chip and this, coupled with its signal switching capability, makes it an ideal solution for data acquisition and memory management.

Working Principle

The 728985JG operates on a basis of logic signals, made up of one or more of two logic levels, i.e. logic one and logic zero. The chip is designed to switch and decode between these two levels and is able to accommodate a wide range of input signals. In order to switch a logic signal, the 728985JG requires an external current source, which can provide the chip with a boost of current when needed.

When a signal reaches the 728985JG chip, it is decoded first and then fed through a logic switch matrix. This allows the chip to quickly determine whether a logic signal is high or low and then switch it appropriately. The chip is able to switch between two logic signals in less than 20 nanoseconds, making it an ideal choice for complex logic circuits and data processing applications.

Furthermore, the 728985JG is designed such that it requires no external power supply. This is an important factor, as it ensures that the chip does not require a vast amount of external current, particularly when used for power-sensitive tasks. Additionally, the chip has a temperature range of -40°C to +85°C which makes it suitable for a wide range of temperatures and applications.

In conclusion, the 728985JG from Microchip Technology, Inc. is a reliable logic chip offering both logic signal switching and decoding capabilities. It is suitable for applications such as serial peripherals, USB bridgeless ports, LCD interfaces and non-volatile memory interfaces, coupled with many pins allowing for multiplexing. In order to operate, the chip requires an external current source and has an operating temperature range of -40°C to +85°C.
