TC74LVX74F/FN/FT
TOSHIBA CMOS Digital Integrated Circuit
Silicon Monolithic
TC74LVX74F,TC74LVX74FN,TC74LVX74FT
Dual D-Type Flip-Flop with Preset and Clear
Note:
The TC74LVX74F/ FN/ FT is a high-speed CMOS D-flip flop
fabricated with silicon gate CMOS technology. Designed for use
in 3-V systems, it achieves high-speed operation while
maintaining the CMOS low power dissipation.
This device is suitable for low-voltage and battery operated
systems.
The signal level applied to the D input is transferred to Q
output during the positive going transition of the CK pulse.
CLR and PR are independent of the CK and are
accomplished by setting the appropriate input low.
An input protection circuit ensures that 0 to 5.5V can be
applied to the input pins without regard to the supply voltage.
This device can be used to interface 5V to 3V systems and two
supply systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input voltages.
xxxFN (JEDEC SOP) is not available in
Japan.

Note: 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).
