TC7MH367,368FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MH367FK,TC7MH368FK HEX Bus Buffer TC7MH367FK Non-Inverted, 3-State Outputs TC7MH368FK Inverted, 3-State Outputs The TC7MH367FK and TC7MH368FK are advanced high speed CMOS HEX 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. They contain six buffers; four buffers are controlled by an enable input (G1), and the other two buffers are controlled by another enable input (G2). The outputs of each buffer group are Weight: 0.02 g (typ.) enabled when G1 and/or G2 inputs are held low; if held high, these outputs are in a high impedance state. The TC7MH367FK is a non-inverting output type, while the TC7MH368FK is an inverting output type. 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.

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
