TC74AC161,163P/F/FN/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC161P,TC74AC161F,TC74AC161FN,TC74AC161FT TC74AC163P,TC74AC163F,TC74AC163FN,TC74AC163FT Synchronous Presettable 4-Bit Binary Counter TC74AC161P/F/FN/FT Asynchronous Clear TC74AC163P/F/FN/FT Synchronous Clear Note: xxxFN (JEDEC SOP) is not available in Japan. TC74AC161P, TC74AC163P The TC74AC161 and 163 are advanced high speed CMOS SYNCHRONOUS PRESETTABLE COUNTERs fabricated with silicon gate and double-layer metal wiring C2MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL 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 these IC’s is synchronous to the rising edge of CK. The clear function of the TC74AC163 is synchronous to CK, while the TC74AC161 are cleared asynchronously. Two enable inputs (ENP and ENT) and CARRY OUTPUT 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 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C should be applied up to 300 mW.
