Dual Binary Counter
The TC74VHC393 is an advanced high speed CMOS 4-BIT BINARY COUNTER 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. It contains two independent counter circuits in one package, so that counting or frequency division of eight binary bits can be achieved with one IC. This device changes state on the negative going transition of the CLOCK pulse. The counter can be reset to "0" (QA to QD = "L") by a high at the CLEAR input regardless of other inputs. 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.
Note: xxxFN (JEDEC SOP) is not available in Japan. TC74VHC393F

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 75 180 -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).

Note:
The operating ranges must be maintained to ensure the normal operation of the device. Unused inputs must be tied to either VCC or GND.
