They achieve the high speed operation similar to equivalent LSTTL 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 TC74HC367A is a non-inverting output type, while the TC74HC368A is an inverting output type. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features Note: xxxFN (JEDEC SOP) is not available in Japan.

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 2: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C shall be applied until 300 mW.
