74LVC1G126
SINGLE BUFFER GATE WITH 3-STATE OUTPUT
Description
The 74LVC1G126 is a single non-inverting buffer/bus driver with a
3-state output. The output enters a high impedance state when a
LOW-level is applied to the output enable (OE) pin. The device is
designed for operation with a power supply range of 1.65V to 5.5V.
The inputs are tolerant to 5.5V allowing this device to be used in a
mixed voltage environment. The device is fully specified for partial
power down applications using I
OFF
. The I
OFF
circuitry disables the
output preventing damaging current backflow when the device is
powered down.

7. Stresses beyond the absolute maximum may result in immediate failure or reduced reliability. These are stress values and device
operation should be within recommend values.
8. Forcing the maximum allowed voltage could cause a condition exceeding the maximum current or conversely forcing the maximum current could
cause a condition exceeding the maximum voltage. The ratings of both current and voltage must be maintained within the controlled range.
