tPLH ≅ tPHL
OPERATING VOLTAGE RANGE:
VCC(OPR) = 2V to 5.5V
IMPROVED LATCH-UP IMMUNITY
DESCRIPTION
The 74V1G126 is an advanced high-speed CMOS
SINGLE BUS BUFFER fabricated with sub-micron
silicon gate and double-layer metal wiring C2MOS
technology.
3-STATE control input 1G has to be set LOW 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.

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
