Signal switches, multiplexers and decoders are integrated circuits (ICs) used to handle high-speed electrical signals. CD74HC147NSR is an example of a signal switch chip that has a wide application field and an advanced working principle. This IC offers significant advantages in speed and low-power operation and is applicable in many industrial and commercial electronics.

CD74HC147NSR is a high speed logic IC with a total of eight TTL compatible input lines. The main purpose of this IC is to carry out multiplexing tasks. It allows for the conversion of a large number of digital high-speed signals into a single signal. Low power consumption and a minimum temperature coefficient make this IC particularly suitable for converting digital signals in mobile devices, such as digital cameras and smartphones.

In addition to multiplexing, the chip is also able to carry out decoding duties. Its 8-bit 8-input decoder allows for converting two 4-bit control signals into 4-bit output signals. This makes it a suitable choice for implementations with low power requirements, such as LED decoders, LED displays, multiplexers and 7-segment programmable displays.

The primary components of the CD74HC147NSR are 8 transistors and a 7-bit register. Each of the transistors feature a higher speed compared to other logic ICs and is made with a special design, making them highly compatible with TTL environments. The combination of transistors and the register allows the chip to switch between multiple signals in quick succession.

The chip implements a predetermined set of commands, allowing for the control and manipulation of data signals. This means that it can examine inputs for any variables or logic condition, and then react accordingly. By doing so, it is able to carry out the multiplexing and decoding tasks efficiently and effectively, while still delivering a high performance when switching between multiple signals.

The chip also offers a high level of noise protection, preventing unwanted signals from causing any disruption or damage to the IC. Furthermore, its low power operation means that the IC is suitable for use in electronics and applications where power consumption is a primary concern.

In conclusion, the CD74HC147NSR is an integrated circuit that has a wide application field and a well-defined working principle. It is capable of handling high-speed digital signals, as well as performing tasks such as multiplexing and decoding effectively and efficiently. Its low power operation, high speed and noise protection make it an ideal choice for applications in mobile devices and low-power environments.
