1.We have an assignment, we need to construct the circuit of calculator using 74147 IC . Can anybody help me on how to hold and shift the data, and also how to have a 0 display.
A 74147 IC, also known as a 10-to-4 line priority encoder, is a digital integrated circuit that converts 10 input signals into a 4-bit binary output. It works by assigning priority to each input signal and encoding them into a binary output based on which input has the highest priority.
To build a calculator circuit with a 74147 IC, you will need to choose the appropriate resistors, capacitors, and other components based on the specifications of the IC and your desired calculations. It is important to carefully read the datasheet of the IC and understand its pin configurations and input/output requirements.
Yes, a 74147 IC can be used for both data holding and shifting in a calculator circuit. It has a built-in latch that holds the input data and a shift register that allows for shifting of the data in a desired direction.
One limitation of using a 74147 IC in a calculator circuit is that it can only handle a maximum of 10 input signals. If you need to handle more than 10 inputs, you may need to use multiple 74147 ICs or consider using a different type of encoder.
A calculator circuit with a 74147 IC can be used in various electronic devices that require data encoding, such as calculators, digital counters, and data storage systems. It is also commonly used in automation systems, traffic control systems, and other digital control systems.
