IC 74147 PDF

For a complete data sheet, please also download. The IC06 Product specification File under Integrated Circuits, IC06 December FEATURES. ICprovides us facility to convert Decimal form of input into Binary form of output. As it convert Human friendly numerical into machine. CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test.

As it convert Human friendly numerical into machine friendly language i. When we press key 5 then by pressing key the voltage in the key no. There are n input lines, only one of which is active.

Encoders | Education Progresses Best When Knowledge is Shared Openly and Freely

When X9 is high it gives priority to X8 and gets encoded if it is low. Create a free website or blog at WordPress.

As we naturally live in a Decimal world, we need some way of converting 741447 Decimal numbers into Binary base-2 environment that computers and digital electronic devices understand, and binary coded decimal allows us to do that.

IC is called priority encoder because it gives priority to highest order input. There are four OR gates are arrange in such a manner that they provides a Binary form of output when we give Decimal form of input.


Encoders are widely used in various devices like Calculators, Computers, Mobile phones, ATM machines and even also in our regular Television.

Encoders are the electronic equipment which converts one form of input into another one.

That means if all inputs from X1 to X9 are low, it gives priority to highest order 9 which is encoded into out as LHHL.

In this circuit we press a decimal numbers which is display on digital electronic device in the form 71447 decimal number. Pin out diagram and logical diagram.

Hi friends if you want to share your project or seminar with other students to help them into 7417 project or seminar then plese kindly share with us. Digital System Hardware S. Encoder converts this active input to the binary coded output with m bits.

Limitations with Decimal to BCD encoder. X9 has priority over all others.

Sc Leave a comment. Notify me of new posts via email. Verify this conversion using online calculator by clicking on http: In above figure we arrange a circuit of Decimal to BCD encoder. In our 21 st century we get digitalized day by day and decimal to binary Encoder performs very important role to communicate Human being with Machine.


To find out more, including how to control cookies, ci here: Every wire is connected to the OR gate. When all X inputs are high, all outputs are high. In above mentioned figure we see a circuit structure of seven segment display which is one of the application of Decimal to BCD encoder.

Project / Seminar by students: Decimal To BCD Encoder

Notice bubble at input and output, which indicated active-low signal. Leave a Reply Cancel 744147 Enter your comment here Encoder is a digital circuit that converts an active signal into a coded output signal. You are commenting using your WordPress.

You are commenting using your Facebook account. When we press decimal numbers then BCD encoder converts it into machine friendly language i. Encoders are used to generate a coded output from a single active numeric input.

In above circuit we arrange 10 key point which is connected to the electric supply and provides decimal from of input to the circuit by passing voltage in a certain wire.

The switches 0 to 9 are push button switches like a pocket calculator.
