双反相施密特触发器 Dual inverting Schmitt trigger
General description
The 74HC2G14; 74HCT2G14 is a high-speed Si-gate CMOS device. The 74HC2G14; 74HCT2G14 provides two inverting buffers with Schmitt trigger action which accept standard input signals. They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. The inputs switch at different points for positive and negative-going signals. The difference between the positive voltage VT+ and the negative voltage VT− is defined as the input
hysteresis voltage VH.
