74HC14 hex Schmitt-trigger inverter IC — TSSOP-14 SMD package

The 74HC14 is a high-speed CMOS hex Schmitt-trigger inverter containing six independent inverting channels, each with hysteresis on the input. The Schmitt-trigger action gives the device excellent noise immunity and the ability to "square up" slow or noisy input signals — making it ideal for signal conditioning, oscillator circuits, and debouncing applications. This listing is for the TSSOP-14 (Thin Shrink Small Outline Package) SMD variant — the most compact footprint of the 74HC14 family, ideal for space-constrained PCB designs.
