74HC147D,653

Logic devices can be used to perform various functions such as switching, multiplexing, decoding, and so on. The 74HC147D,653 application field and working principle is one such logic device that is commonly used in many systems. The 74HC147D is a logic multiplexer that is used to select either one of the two binary inputs for a logic 0 or logic 1 output. It can select one of the two binary inputs based on the select signal that is applied to the device. The device is also capable of performing 4-to-16 decoder/demultiplexer function.

The 74HC147D is a logic multiplexer that is used to select either one of the two binary inputs for a logic 0 or logic 1 output. The select signal is a single bit that determines which of the two inputs is selected. The device can handle any input levels, allowing it to be used with various logic families such as CMOS, TTL, and others. It also includes three-state outputs, meaning the outputs can be enabled and disabled by an external control signal.

The 74HC147D is based on a diode matrix technology which uses diodes to select one of the two input signals. The two inputs are applied to the gate terminals and the select signal is applied to the select terminal. When the select signal is high, the input at the gate A terminal is pulled to a logic 1, and the output is set to a logic 1. Likewise, when the select signal is low, the input at the gate B terminal is pulled to a logic 1, and the output is set to a logic 1. This allows for a single binary output based on the select signal and the two input signals.

The 74HC147D can also be used as a 4-to-16 decoder/demultiplexer. When the device is used in this mode, the two inputs should be connected to a binary selection signal. The select terminals are then connected to the binary selection signal. The output is then connected to the decoded bit representing the binary selection signal. This allows for four different outputs to be sent, depending on the binary selection signal.

Overall, the 74HC147D,653 application field and working principle is a simple yet effective logic multiplexer and 4-to-16 decoder/demultiplexer. It can be used to select one of two binary inputs for a logic 0 or logic 1 output and can also be used to decode up to four different selection signals. With its wide range of applications and simple logic implementations, the 74HC147D is often used in many systems to perform logic functions.
