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% VCCmin

•  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
