| TC74ACT161,163P/F/FN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT161P,TC74ACT161F,TC74ACT161FN TC74ACT163P,TC74ACT163F,TC74ACT163FN Synchronous Presettable 4-Bit Binary Counter TC74ACT161P/F/FN Asynchronous Clear TC74ACT163P/F/FN Synchronous Clear The TC74ACT161 and T163 are advanced high speed CMOS SYNCHRONOUS PRESETTABLE 4 BIT BINARY 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. These devices may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are compatible with TTL, NMOS and CMOS output voltage levels. 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 TC74ACT163 is synchronous to CK, while the TC74ACT161 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. Note: xxxFN (JEDEC SOP) is not available in Japan.

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 should be applied up to300 mW.
