HC4049
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.
HC4050
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 2stage 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.

CPD isdefined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer
to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC (per Gate)
