PIN AND FUNCTION COMPATIBLE WITH
74 SERIES 4050
DESCRIPTION
The M74HC4049 is an high speed CMOS HEX
BUFFER fabricated with silicon gate C
2
MOS
technology.
The internal circuit is composed of 3 stages, 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.
