Hex Bus Buffer TC74VHC367F/FN/FT Non-Inverted, 3-State Outputs TC74VHC368F/FN/FT Inverted, 3-State Outputs
The TC74VHC367 and 368 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 enabled when G1 and/or G2 inputs are held low; if held high, these outputs are in a high impedance state. The TC74VHC367 is a non-inverting output type, while the TC74VHC368 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.

Characteristics Supply voltage range DC input voltage DC output voltage Input diode current Output diode current DC output current DC VCC/ground current Power dissipation Storage temperature Symbol VCC VIN VOUT IIK IOK IOUT ICC PD Tstg Rating -0.5 to 7.0 -0.5 to 7.0 -0.5 to VCC + 0.5 -20 20 25 50 180 -65 to 150 Unit V V V mA mA mA mA mW C
Note:
Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. 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).

Note:
The operating ranges must be maintained to ensure the normal operation of the device. Unused inputs must be tied to either VCC or GND.
