TC74AC163FT Datasheet PDF - Toshiba

●Synchronous Presettable 4-Bit Binary Counter

●TC74AC161P/F/FT Asynchronous Clear

●TC74AC163P/F/FT Synchronous Clear

●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.

●Features

●•  High speed: fmax= 170 MHz (typ.) at VCC= 5 V

●•  Low power dissipation: ICC= 8 μA (max) at Ta = 25°C

●•  High noise immunity: VNIH= VNIL= 28% VCC(min)

●•  Symmetrical output impedance: |IOH| = IOL= 24 mA (min)

●                                             Capability of driving 50 Ω transmission lines.

●•  Balanced propagation delays: tpLH∼  − tpHL

●•  Wide operating voltage range: VCC (opr)= 2 to 5.5 V

●•  Pin and function compatible with 74F161/163
