description
This single bus buffer gate is designed for 1.65-V to 5.5-V V_CC operation.
The SN74LVC1G126 is a single bus driver/line driver with a 3-state output. The output is disabled when the
output-enable (OE) input is low.
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a
pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the
driver.
This device is fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
The SN74LVC1G126 is characterized for operation from –40°C to 85°C.
