TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74HC273AP, TC74HC273AF
Octal D-Type Flip Flop with Clear
The TC74HC273A is a high speed CMOS OCTAL D-TYPE
FLIP FLOP fabricated with silicon gate C
2
MOS technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
Information signals applied to D inputs are transferred to the
Q outputs on the positive going edge of the clock pulse.
When the
CLR
input is held “L”, the Q outputs are at a low
logic level independent of the other inputs.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.

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: 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.
