DESCRIPTION
The M74HC368 is an high speed CMOS HEXBUS BUFFER 3-STATE OUTPUTS fabricatedwith silicon gate C2MOS technology.
This device contains six buffers, four buffers arecontrolled by an enable input (G1) and the othertwo buffers are controlled by the other enableinput (G2); the outputs of each buffer group are
enabled when G1 and/or G2 inputs are held low,and when held high, these outputs are disabled ina high-impedance state.
All inputs are equipped with protection circuitsagainst static discharge and transient excessvoltage.

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/6 (per Channel)
