TC74VHC4020F/FT/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VHC4020F,TC74VHC4020FT,TC74VHC4020FK
14-Stage Ripple Carry Binary Counter
The TC74VHC4020 is an advanced high speed CMOS 14-STAGE BINARY COUNTER/DIVIDER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. Setting CLR to high resets the counter to low. A negative transition on the CK input brings one increment into the counter. This counter provides all divided output stages, and at Q12, a 1/4096 divided frequency will be output. An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.

Absolute Maximum Ratings (Note)
Characteristics Supply voltage range DC input voltage DC output voltage Input diode current Output diode current DC output current DC VCC/ground current Power dissipation Storage temperature Symbol VCC VIN VOUT IIK IOK IOUT ICC PD Tstg Rating -0.5 to 7.0 -0.5 to 7.0 -0.5 to VCC + 0.5 -20 20 25 100 180 -65 to 150 Unit V V V mA mA mA mA mW 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).
