DESCRIPTION
The M54/74HC4049 and the M54/74HC4050 are
high speed CMOS HEX BUFFER fabricated in sili-
con gate C
2
MOS technology.
They have the same high speed performance of
LSTTL combined with true CMOS low power con-
sumption.
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鈥檚.
The VCC side diodes are designed to allow logic-
level convertion from high-level voltages (up to
15 V) to low-level voltages.
