TC74VHC540,541F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC540F, TC74VHC540FK TC74VHC541F, TC74VHC541FK Octal Bus Buffer TC74VHC540F/FK TC74VHC541F/FK Inverted, 3-State Outputs Non-Inverted, 3-State Outputs TC74VHC540F, TC74VHC541F The TC74VHC540/TC74VHC541 are advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The TC74VHC540 is an inverting type, and the TC74VHC541 is a noninverting type. When either G1 or G2 are high, the terminal outputs are in the highimpedance state.z An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.
