Sometimes the best inspiration is limitation. The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparato… ...

The 555 Design Contest shook a whole bunch of really creative circuits out of the trees, hence the 555-heavy content lately. While not technically part of the contest, [esalazar] wanted to know wha… ...

He used a 555 timer that outputs a clock to the LEDs on the biz card, and placing a nine-volt battery on the terminals sets off the mini light show. See for yourself in the video below.

Please pay Maxim whatever they ask rather than think you can cheap-out with a 555 timer. 2. Maxim s DS1233 power-on-reset chip comes in a tiny TO-92 package, as well as a tiny surface-mount SOT ...

A timer-controlled doorbell device has been developed using two 555 timer ICs in monostable mode, combined with a relay ...

The 555 timer IC has been reinvented—again. Signetics introduced the enormously popular chip back in 1971, and it quickly became a big hit. Myriad application circuits have used it throughout ...

Ever wanted a 555 timer with complementary non-overlapping outputs. The XTR651 from X-Rel Semiconductor is just such a thing. Very similar to the good old 555, it includes a built-in 200pF timing ...
