TC74VHC161,163F/FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC161F,TC74VHC161FT,TC74VHC161FK TC74VHC163F,TC74VHC163FT,TC74VHC163FK Synchronous Presettable 4-Bit Counter TC74VHC161F/FT/FK Binary, Asynchronous Clear TC74VHC163F/FT/FK Binary, Synchronous Clear The TC74VHC 161 and 163 are advanced high speed CMOS SYNCHRONOUS PRESETTABLE 4 BIT BINARY COUNTERs fabricated with silicon gate 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 each IC's is synchronous to the rising edge of CK. The clear function of the TC74VHC163 is synchronous to CK, while the TC74VHC161 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. 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.
