TC4040BFN
TC4040B 12 Stage Ripple-Carry Binary Counter/Dividers
TC4040B is 12 stage ripple carry binary counter having
asynchronous clear function. This 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 through Q12) to be “L”.
This is most suitable for frequency dividers, control circuits
and timing circuits.

DC supply voltage VDD V
SS − 0.5 to VSS + 20 V
Input voltage VIN V
SS − 0.5 to VDD + 0.5 V
Output voltage VOUT V
SS − 0.5 to VDD + 0.5 V
DC input current IIN ±10 mA
Power dissipation PD 180 mW
Operating temperature range Topr −40 to 85 °C
Storage temperature range Tstg −65 to 150 °C
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).
