Digital System Board should have enough decoupling capacitors. Ideally each VCC pin of a device should have a decoupling capacitor. If the device has VCC pins pretty close to each other (like pins 1,2,3 & 4) then upto 4 VCC pins can be combined and provided with one bigger decoupling capacitor. Also refer to manufacturers […]

In Digital System Board Design, It is suggested to Tie high or low all the CMOS floating and unused inputs. Leaving inputs floating causes gate puncture (gates goes to intermediate logic creating a low resistance path to the ground thereby damaging the device). It is recommended to tie the TTL unused inputs to logic low […]

In digital communications systems, there are 2 methods for data transfer: parallel and serial. Parallel communication uses multiple wires running parallel to each other, and can transmit data on all the wires simultaneously. Serial communication on the other hand, uses a single wire to transfer the data bits one at a time. What is the […]
