A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.

Abstract: In this article, a simple and compact eight-phase divide-by-2 frequency divider (FD) is presented and fabricated using the Taiwan Semiconductor Manufacturing Company (TSMC) 180-nm CMOS ...

Expert DIYer Katy French creates renter-friendly plant screen dividers using an easy DIY trellis. Arkansas to become first state to cut ties with PBS: 'Not feasible' Lady Gaga abruptly stops Mayhem ...

One of the categories we chose for the One Hertz Challenge is “Could Have Used a 555.” What about when you couldn’t have, but did anyway? The 555 is famously easy to use, but not exactly the most ...

The 555 timer is one of the most versatile integrated circuits available. It can generate PWM signals, tones, and single-shot pulses. You can even put one in a bi-stable mode similar to a flip flop.

Abstract: We demonstrate the design and analysis of a K-band (18-27 GHz) divide-by-4 injection-locked frequency-divider (ILFD4) in 90 nm CMOS. A wideband balun is used for converting the single-ended ...

This is a simple LED Cube circuit designed using 555 timer. It can be very useful for home decoration purpose and home lighting systems. Many LED Cube circuits are available in the markets which are ...
