DESCRIPTION
The M54/74HC125/126 are high speed CMOS
QUAD BUS BUFFER (3-STATE) FABRICATED IN
SILICON GATE C2MOS technology.
They have the same high speed performance of
LSTTL combined with true CMOS low power con-
sumption.
These devices require the same 3-STATE control
input G to be taken high to make the output go into
the high impedance state.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.

(*) 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 operting current can be obtained by the following equation. ICC(opr) = CPD VCC fIN + ICC
