The M74HC4049 is a high-speed CMOS Hex Buffer (Inverting) fabricated with silicon gate C2MOS technology. The internal circuit is composed of 2 stage inverters, which enables high noise immunity and a stable output. Input protection circuits are different from those of the high speed CMOS IC's. The Vcc side diodes are designed to allow logic-level conversion from high-level voltages (up to 13V) to low level voltages.
