TC74LCX574F/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LCX574F, TC74LCX574FK
Low-Voltage Octal D-Type Flip-Flop with 5-V Tolerant Inputs and Outputs
The TC74LCX574 is a high-performance CMOS octal D-type flip-flop.
Designed for use in 3.3-V systems, it achieves high-speed operation
while maintaining the CMOS low power dissipation.
The device is designed for low-voltage (3.3 V) VCC applications, but it
could be used to interface to 5 V supply environment for both inputs and
outputs.
This 8-bit D-type flip-flop is controlled by a clock input (CK) and an
output enable input ( OE ). When the OE input is high, the eight
outputs are in a high-impedance state.
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).
Note 2: Output in OFF state
Note 3: High or low state. IOUT absolute maximum rating must be observed.
