TC74HC367,368AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC367AP, TC74HC367AF TC74HC368AP, TC74HC368AF Hex Bus Buffer TC74HC367AP/AF Non-Inverted TC74HC367AP, TC74HC368AP (3-state) TC74HC368AP/AF Inverted (3-state) The TC74HC367A and TC74HC368A are high speed CMOS 2 3-STATE BUS BUFFERs fabricated with silicon gate C MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. TC74HC367AF, TC74HC368AF 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.
