TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LCX74F,TC74LCX74FT,TC74LCX74FK
Low-Voltage Dual D-Type Flip-Flop with 5-V Tolerant Inputs and Outputs
The TC74LCX74 is a high-performance CMOS D-type flip-flop.
Designed for use in 3.3-V systems, it achieves high-speed
TC74LCX74F
operation while maintaining the CMOS low power dissipation.
The device is designed for low-voltage (3.3 V) V
applications,
CC
but it could be used to interface to 5-V supply environment for
inputs.
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.
All inputs are equipped with protection circuits against static
discharge.

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).
