The 74LVC2G126 is a dual buffer gate with 3-state outputs. The
device is designed for operation over a power supply range of 1.65V
to 5.5V. The device is fully specified for partial power down
applications using IOFF. The IOFF circuitry disables the output,
preventing damaging current backflow when the device is powered
down.

Features
Wide Supply Voltage Range from 1.65 to 5.5V
± 24mA Output Drive at 3.3V
CMOS Low Power Consumption
IOFF Supports Partial-Power-Down Mode Operation
Inputs accept up to 5.5V
Schmitt Trigger Action at all inputs makes the circuit tolerant
for slower input rise and fall times. The hysteresis is typically
100mV at VCC = 3.0V.
ESD Protection Exceeds JESD 22
