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 consumption.
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 voltage.

■ HIGH SPEED
   tPD = 8 ns (TYP.) AT VCC = 5 V
