The MC14583B is a dual Schmitt trigger constructed with complementary Pchannel and Nchannel MOS devices on a monolithic silicon substrate. Each Schmitt trigger is functionally independent except for a common 3state input and an internallyconnected Exclusive OR output for use in line receiver applications. Trigger levels are adjustable through the positive, negative, and common terminals with the use of external resistors. Applications include the speedup of a slow waveform edge in interface receivers, level detectors, etc.
