DESCRIPTION
The 74LX 1G126 is a low v olt age CMOS SINGLE BUS B UFF ER fabricated with sub-micron silicon gate and double-layer metal wiring C
2
MOS technology. 3-STATE control input G has to be set LOW to place the output into the high impedance state.
Power down prot ection is provided on all inputs and 0 to 7V c an be accepted on inp uts with no regard to the supply voltage. This device can be usedto interface5V to 3V. All inputs and outputs are equipped with protection circuits against static discharge.
