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 ...
The miniature 74AUP2G family of advanced ultra-low power CMOS logic devices include seven versions of dual inverters and buffers. The chips use a 0.8 to 3.6 V supply, have ±4 mA output drive at 3 V, ...
