DESCRIPTIONThe M74HC126 is an high speed CMOS QUAD
BUFFER (3-STATE) fabricated with silicon gate2 MOS 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 = 6ns)
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. ICC(opr) = CPD x VCC x fIN + ICC/4(per buffer)
M74HC1265/10
TEST CIRCUIT CL = 50pF/150pF or equivalent (includes jig and probe capacitance)
R1 = 1KΩ or equivalent
RT = ZOUT of pulse generator (typically 50Ω)
