74C14 Overview
The MM74C14 Hex Schmitt Trigger is a monolithic plementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement transistors. The positive and negative going threshold voltages VT+ and VT−, show low variation with respect to temperature (typ. 0.0005V/°C at VCC = 10V), and hysteresis, VT+ − VT− ≥ 0.2 VCC is guaranteed.
