74HC4049D,74HC4050D CMOS Digital Integrated Circuits Silicon Monolithic 74HC4049D,74HC4050D 1. Functional Description • Hex Buffer 74HC4049D: HEX BUFFER/CONVERTER (INVERTING) 74HC4050D: HEX BUFFER/CONVERTER 2. General The 74HC4049D and 74HC4050D are high speed CMOS HEX BUFFERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The 74HC4049D is an inverting buffer, while the 74HC4050D is a non-inverting buffer. The internal circuits are composed of 3-stages (74HC4049D) or 2-stages (74HC4050D) of inverter, which provided high noise immunity and stable output. Input protection circuits are different from those of other high speed CMOS IC's.
