Another way to preset /reset the 555. Open collector comparators etc. work well as an interface to the 555. Input current. Reset current maxed out at 0V. Actual range was -13 to -33uA. The minus sign ...

The classic and versatile 555 finds its way into many low to moderate frequency oscillator applications. Some of these require the ability to selectively gate oscillation on and off on demand and the ...

If you’re not familiar with the 555 timer, ... It’s available in a variety of 8-pin packages, including DIP, SOIC, and VSSSOP, in order of decreasing size.

To that end, two types of 555 timers are in use today, both being eight-pin chips. The most common is the rectangular “V” package, which has four pins down each side.

555 could use a refresh, save some pins – I think pin 4 (RESET) needs to get deleted, it’s mostly useless and maybe the 2-6 tie. But we’re all kinda tired of the articles on uses for it, ...

The 555 timer IC is an integrated circuit (chip) which is used in a variety of timer, delay, pulse generation, and oscillator applications. 555 Signals and Pinout (8 pin DIP) Figure below shows ...
