TC74VHC161,163F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC161F, TC74VHC161FK TC74VHC163F, TC74VHC163FK Synchronous Presettable 4-Bit Counter TC74VHC161F/FK Binary, Asynchronous Clear TC74VHC163F/FK Binary, Synchronous Clear TC74VHC161F, TC74VHC163F The TC74VHC 161 and 163 are advanced high speed CMOS SYNCHRONOUS PRESETTABLE 4 B.
High speed: fmax = 185 MHz (typ.) at VCC = 5 V
Low power dissipation: ICC = 4 μA (max) at Ta = 25°C
High noise immunity: VNIH = VNIL = 28% VCC (min)
Power down protection is provided on all inputs.
Balanced propagation delays: tpLH ∼− tpHL
Wide operating voltage range: VCC (opr) = 2 to 5.5 V
Low noise: VOLP = 0.8 V (max)
Pin and function compatible with 74ALS161/163
