M74HC4049 General Description
The M54/74HC4049 and the M54/74HC4050 are high speed CMOS HEX BUFFER fabricated in silicon gate C2MOS technology.
They have the same high speed performance of LSTTL combined with true CMOS low power consumption. The M54/75HC4049 is an inverting buffer, while the M54/74HC4050 is a non-inverting buffer. The internal circuit is composed of 3 stage or 2- stage inverters, which provides 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 logiclevel convertion from high-level voltages (up to 15 V) to low-level voltages.
