Lot of 5 CD74HCT14E hex Schmitt-trigger inverter logic ICs.

These parts are marked “CD74HCT14E” with date/lot code “H 8949,” as shown in the photographs. The CD74HCT14E is a high-speed CMOS 74HCT-family logic device containing six independent inverting gates with Schmitt-trigger inputs. Schmitt-trigger inputs are useful for cleaning up slow or noisy signals and converting them into stable digital logic transitions.
