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 ...

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 ...

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 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 ...
