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 ...

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 ...

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 ...

The HEF4093B is a quad 2-input NAND gate with Schmitt trigger circuit in each input. The device features Schmitt trigger input discrimination, fully static operation, and standardized symmetrical ...

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 ...

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.

More undocumented applications for the 555 ‘oscillator:’ Not all applications oscillate as we will see. Most are knowledgeable about common CMOS logic inverters and Schmitt triggers such as the 74HC04 ...

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 ...

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 ...
