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 invertingbuffer,whilethe
M54/74HC4050 is a non-inverting buffer.
The internal circuit is composed of 3 stage or 2stageinverters, whichprovides 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.
