TC74HC161,163AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC161AP,TC74HC161AF TC74HC163AP,TC74HC163AF Synchronous Presettable 4-Bit Counter TC74HC161AP/AF Binary, Asynchronous Clear TC74HC163AP/AF Binary, Synchronous Clear The TC74HC161A and 163A are high speed CMOS BINARY PRESETTABLE COUNTERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The CK input is active on the rising edge. Both LOAD and CLR inputs are active on low logic level. Presetting of their IC's is synchronous to the rising edge of CK. The clear function of the TC74HC163A is synchronous to CK, while the TC74HC161A is cleared asynchronously. Two enable inputs (ENP and ENT) and CO are provided to enable easy cascading of counters, which facilitates easy implementation of n-bit counters without using external gates. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

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 2: 500 mW in the range of Ta = -40 to 65C. From Ta = 65 to 85C a derating factor of -10 mW/C shall be applied until 300 mW.
