TC74HC4049AP, TC74HC4050AP
The TC74HC4049A and TC74HC4050A are high speed CMOS
HEX BUFFERs fabricated with silicon gate C2MOS technology.
They achieve the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The TC74HC4049A is an inverting buffer, while the
TC74HC4050A is a non-inverting buffer. The internal circuits are
composed of 3-stages (HC4049A) or 2-stages (HC4050A) of
invertaers, which provided high noise immunity and stable

output.
Input protection circuits are different from those of other high
speed CMOS IC’s. They eliminate the diodes on the V
side
thus providing of logic-level conversion from high-level volages
up to 15 V to low-level voltages.
CC
They are useful for battery back up circuits, because input
voltage can be applied on IC’s which are not biased by V
.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 2: DC input voltage (V ) specified is measured to GND and is not related to V
.
IN CC
Recommended operating range is 0 V to 15 V and it is possible to convert logic-levels from 15 V to 5 V or 5
V to 2 V.
Note 3: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C shall be
applied until 300 mW.
