TC4027BF

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).

TC4027BF is J-K master-slave flip-flop having RESET and SET functions.

In the case of J-K made, when the clock input is given with both RESET and SET at "L", the output changes at rising edge of the clock according to the states of J and K.

When SET input is placed at "H", and RESET input is placed at "L", outputs become Q = "H", and Q = "L". When RESET input is placed at "H", and SET input is placed at "L", outputs become Q = "L", and Q = "H".

When both of RESET input and SET input are at "H", outputs become Q = "H" and Q = "H".
