TC7MH540,541FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MH540FK,TC7MH541FK Octal Bus Buffer TC7MH540FK Inverted, 3-State Outputs TC7MH541FK Non-Inverted, 3-State Outputs The TC7MH540FK and TC7MH541FK 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 TC7MH540FK is an inverting type, and the TC7MH541FK is a non-inverting type. When either G1 or G2 are high, the terminal outputs are in the Weight: 0.03 g (typ.) high-impedance state. An input protection circuit ensures that 0 to 7 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.
