DESCRIPTION
The M54HC4050 is an high speed CMOS HEX BUFFER fabricated with silicon gate C2MOS
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.

■ HIGH SPEED: tPD= 8ns (TYP.) at VCC=6V
■ LOW POWER DISSIPATION: ICC=1µA(MAX.) at TA=25°C
■ HIGH NOISE IMMUNITY: VNIH=VNIL= 28% VCC(MIN.)
■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH|=IOL=6mA(MIN)
■ BALANCED PROPAGATION DELAYS: tPLH≅tPHL
■ WIDE OPERATING VOLTAGE RANGE: VCC(OPR) = 2V to 6V
■ PIN AND FUNCTION COMPATIBLE WITH 54 SERIES 4050
