TC7MZ574FK
Low Voltage Octal D-Type Flip-Flop with 5 V Tolerant Inputs and Outputs
The TC7MZ574FK 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) V
applications,
CC
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.
Weight: 0.03 g (typ.)

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).
