Octal Bus Buffer

TC74AC540P/F/FT Inverting, 3-State Outputs

TC74AC541P/F/FT Non-Inverting, 3-State Outputs

The TC74AC540/TC74AC541 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. The TC74AC540 is an inverting type, and the TC74AC541 is a non-inverting type.

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 74F540/541
