The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparators, a voltage ladder, and a flip-flop.

Both designs were presented to the group, and both worked well. Both used a 5-V supply, which can be supplied through a USB connector. It is interesting to also note the similarities of both designs: ...

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 ...

Semtech has introduced an analogue timer chip that runs from 0.9V, but can drive LEDs at over 3V. Called SX8122, to the timer it adds: a simple battery charger, a boost converter, and a power-down ...

The 555 timer IC has been around now for quite some time and the list of potential uses for this device appears to be endless. This article contains ... Comparator 1 is biased at 2/3 the supply ...

Hans Camenzind, the designer of the popular 555 timer IC died this week in Silicon Valley. ... VCO, phase-locked loop, comparator, PWM modulator, frequency divider and DC-DC converter.
