Click to enlarge Video demo Function: - One of the most popular electronic IC number. There are many different symbols depending on the firm and ability to meet such as 74HC47, 74HCT47, 74LS47,. Application: This is a sign dedicated decoder IC for LED 7-segment common anode. Application when it needs to display the number on the LED 7-in digital circuit without using the processor or want to save the foot.'' The mode of operation: - Map of principle: As the diagram above, in which A, B, C, D (Connect with the processor, pulse the counter ,...), BI / RBO, RBI, LT (7447 foot control, depending on different needs will be connected), Chan QA, QB, QC, QD, QE, QF, QG, respectively connected to pin a, b, c, d, e, f, g of common anode 7-segment LED. - Describe how the following activities: PORT A, B, C, D: input of 7447, receiving the binary value (BCD) from 0 to 15, corresponding to each value received will decode the...
