74LVC125A
QUADRUPLE 3-STATE BUFFERS
Description
Pin Assignments
The 74LVC125A provides four independent buffers with three state
outputs. Each output is independently controlled by an associated
output enable pin (OE) which places the device in the high
impedance state when driven high. 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 IOFF.
The IOFF circuitry disables the output
preventing damaging current backflow when the device is powered
down.
