DM74LS14 Hex Inverter with Schmitt Trigger Inputs

1 2000 Fairchild Semiconductor 1986 Revised March 2000DM74LS14 Hex Inverter with Schmitt Trigger InputsDM74LS14 Hex Inverter with Schmitt Trigger InputsGeneral DescriptionThis device contains six independent gates each of whichperforms the logic INVERT function. Each input has hyster-esis which increases the noise immunity and transforms aslowly changing input signal to a fast changing, jitter freeoutput.
