TC4020BP/BF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC4020BP, TC4020BF TC4020B 14 Stage Ripple-Carry Binary Counter/Dividers TC4020B is 14 stage ripple carry binary counter having asynchronous clear function. The counter advances its counting stage by falling edge of CLOCK input. When RESET input is placed "H", all the circuits are reset regardless of CLOCK input making all the outputs (Q1, Q4 to Q14) to be "L". This is most suitable for frequency dividers, control circuits and timing circuits. TC4020BP Pin Assignment TC4020BF Weight DIP16-P-300-2.54A SOP16-P-300-1.27A : 1.00 g (typ.) : 0.18 g (typ.)

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).
