Overview
The MC14584B Hex Schmitt Trigger, produced by onsemi, is a versatile integrated circuit constructed with MOS P-channel and N-channel enhancement mode devices in a single monolithic structure. This device is particularly useful in applications where low power dissipation and high noise immunity are essential. It can be used to replace the MC14069UB hex inverter to enhance noise immunity and to 'square up' slowly changing waveforms.
