TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74HCT374AP,TC74HCT374AF
Octal D-Type Flip-Flop with 3-State Output
The TC74HCT374A is high speed CMOS OCTAL FLIP-FLOP
with 3-STATE OUTPUT fabricated with silicon gate C2MOS
technology.
TC74HCT374AP
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
Their inputs are compatible with TTL, NMOS, and CMOS
output voltage levels.
This 8-bit D-type flip-flop is controlled by a clock input (CK)
and an output enable input ( OE ).
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.
