DESCRIPTION
The 74LX1G125 is a low voltage CMOS SINGLE
BUS BUFFER fabricated with sub-micron silicon
gate and double-layer metal wiring C2MOS
technology.
3-STATE control input G has to be set HIGH to
place the output into the high impedance state.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage. This device can be
used to interface 5V to 3V or lower power supply
systems. The sub-micron CMOS technology used

allow ultra low power consumption and guarantee
optimized operations between 2.8V and 1.8V
system, as Smart Phone, Digital Still Camera,
PDA, Notebook, or each other battery powered
equipment.
All inputs and outputs are equipped with
protection circuits against ESD discharge.

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
