integrated circuit - Electrical Engineering Stack Exchange I am following an online tutorial It needs Hex Schmitt Trigger Inverter IC (74C14 ) but I can't find it anywhere Instead, I can see CD40106BE Inverter, Schmitt Trigger, CD40106, 1 Input, 3V to 18
digital logic - Electrical Engineering Stack Exchange General details about this IC (7414), Its features and benefits, Its application, Its important electrical characteristics, and everything that you surmise important about this IC that must I point out
switches - Electrical Engineering Stack Exchange Calculated : \$ (5v-0 6v) 6000 \$ - Gives about 7 3mA But with your 8 2K resistor, the current will be less Also, it might be that your 7414 is the LS (Low power version, which would be even less current) Look at the lower schematic in data sheet where 20K resistor is used \$\endgroup\$ –
inverter - Electrical Engineering Stack Exchange Recently bought some TI SN74HC14 Hex Inverter IC's to learn and am having weird issues with them I've looked at many examples online and have tried wiring them the same with the same passive values
In a 74HC14 Schmitt trigger IC, unused inputs outpus The 74HC14 isn't TTL, it's CMOS, and what matters is that the input pins be kept from floating The reason is because the impedance of the input pins is so high when they're floating that random charges accumulating there can will cause unpredictable internal behavior in the chip, including oscillation and high power dissipation
What can reduce overshoot and ringing on a simple square wave pulse . . . From the looks of the new scope traces added to the question, specifically the Vcc trace, it appears that the ringing is originating in poor regulation of the supply at the point of use - most likely not at the bench supply output
