It has become a bit of a running joke in the Hackaday community to suggest that a project could or should have been done with a 555 timer. [Tim] has rather taken this to heart with his latest ...

In 1938, the Journal of Scientific Instruments published details of a comparator circuit that converted a slowly varying input signal into an abrupt change in output voltage. Based on cross-coupled ...

The 74AHC14 and 74AHCT14 are Hex inverting Schmitt triggers that offers six inverting buffers with Schmitt-trigger action. These high-speed Si-gate CMOS devices are pin compatible with Low-power ...

The XC7SET14 is a high speed inverting Schmitt trigger. It functions as an inverting buffer with Schmitt trigger action. It features symmetrical output impedance, high noise immunity, low power ...

Among other interface problems, contact bounce complicates the connection of mechanical contacts or any noisy digital input signal to a microcontroller. Although designers have proposed a variety of ...

D-type flip-flops, with the invertedoutput connected to theD input, can toggle a clock signal. Ifyour circuit has an extra Schmitt-triggerinverter gate, you can use it to accomplishthe same thing.

The circuit in Figure 1 is a single-supply version of a programmable Schmitt trigger, or a comparator with hysteresis. A comparator, A1, and a digitally programmable potentiometer (DPP1) are used for ...

In biomedical instrumentation (for example), we're sometimes faced with very noisy or badly-behaved signals from which we need to derive information. In this example, I needed to “square up” a ...

The XC7SH14 is a high-speed inverting Schmitt trigger. This CMOS device offers an inverting buffer action function with Schmitt trigger action. It features symmetrical output impedance, high noise ...
