74HC2G14集成电路（IC）的门反相器规格书PDF中文资料

1. General description

The 74HC2G14; 74HCT2G14 is a dual inverter with Schmitt-trigger inputs. Inputs include clamp

diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of

VCC. Schmitt trigger inputs transform slowly changing input signals into sharply defined jitter-free

output signals.
