Octal Bus Buffer

●The TC74AC240 and 244 are advanced high speed CMOS OCTAL BUS BUFFERs 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: tpd= 4.0 ns (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 74F240/244
