DESCRIPTION
The M54HC125 is an high speed CMOS QUAD BUFFER (3-STATE) fabricated with silicon gate C 2MOS technology. The device requires the 3-STATE control input G to be set high to place the output into the high impedance state. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

AC ELECTRICAL CHARACTERISTICS (Input tr=tf=6 n s ) CAPACITIVE CHARACTERISTICS 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.
