If you’re not familiar with the 555 timer, suffice it to say that this ... with a maximum frequency of 3 MHz according to the datasheet. It’s available in a variety of 8-pin packages ...
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% ...
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 ...
