then ultimately ended up building the three main logic blocks inside the familiar timer on pieces of copper-clad board. He’d built a 555 using discrete components. While this isn’t 100% ...

If you’re not familiar with the 555 timer, suffice it to say that this versatile integrated circuit is probably the most successful ever designed, and has been used in countless designs ...

The salient features of 555 timer ICs are Compatible with both TTL and CMOS logic families. The maximum load current can go up to 200 mA. The typical power supply voltage is from + 5 V to + 18 V. It ...
