A Schmitt inverter switches with hysteresis, which means it has:

two switching thresholds (upper and lower)

A Schmitt inverter switches its output low only when the input:

rises above the upper threshold

It stops noise or a slow input causing repeated switching

a programmable integrated circuit

its behaviour can be changed by reprogramming

Through a transistor, MOSFET or relay

so the program repeats and keeps checking the inputs

conditioned with a divider, comparator or Schmitt inverter

one programmable chip replaces many logic gates, cheaply and flexibly

Transistor to drive a high-current load
