Use a simply debouncing cct.

Posted by citra on Mei 18, at 8: Hi all, I found a good schematic for a four decade counter using IC’s with a switch debouncing circuit as well. Posted by M Iman Syahrulloh on November 24, at 2: My problem is related to these components. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Pioneer Elite vsxtx water damage dataeheet power Started by Watin Today at For proper work You need proper signal source.

Indicator segments requiring up to catasheet mA of current may be driven directly from the SN74LS47 jc performance output transistors. PLease I wanna make the 74ls90 work as a Decade 6 Counter if you got any idea about this please inform me.

The circuits accept 4-bit binary-coded-decimal BCD and, depending on the state of the auxiliary inputs, decodes this data to drive a 7-segment display indicator. I’m been playing with it for sometime and tried the net but couldnt find anything specific. Welcome to our site! Mau tanya mas yg simbol X pada Tabelnya itu pengertiannya apa?

Gambar Bentuk Tampilan 7 segmen.

Your circuit does not appear to have any bypass capacitors. These outputs will withstand 15 V with a maximum reverse current of xA. Assalamualaikum, Selamat siang mas Fahmi, Ada beberapa hal yang ingin saya tanyakan: Datsheet September 14, by Fahmizal in Elektronika. Update I got the circuit working, the problem why it was only displaying a 9 and a 0 was because 2 of the output leads were connecting underneath where i could see.

Samcheetah, the logic inputs always need H or L level. Posted by wiienn on April 25, at Mr Replay New Member Nov 28, Dari gambar diatas bisa diketahui bahwa hanya sebagian kecil saja dari karakter yang dapat ditampilkan oleh display 7 segmen.


Counter using 74LS90 and 74LS47

Untuk mengetahui lebih lanjut, termasuk cara mengontrol cookie, lihat di sini: The relative positive-logic output levels, as well as conditions required at the auxiliary inputs, are shown in the truth tables. B When a LOW level is applied to the blanking input forced condition all segment outputs go to a LOW level regardless 74ls4 the state of any other input condition. Isikan data di bawah atau klik salah satu od untuk log in: I built that circuit in electronics worbench and it acts like datashewt.
