DESCRIPTION

The M54/74HC4049 and the M54/74HC4050 are

high speed CMOS HEX BUFFER fabricated in sili-

con gate C

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’s.

The VCC side diodes are designed to allow logic-

level convertion from high-level voltages (up to

15 V) to low-level voltages.
