3 Description
These octal buffers/drivers with inverted outputs are
designed for 2-V to 5.5-V V_CC operation.
The ’LV240A devices are designed specifically to
improve both the performance and density of 3-state
memory address drivers, clock drivers, and bus-
oriented receivers and transmitters.
These devices are organized as two 4-bit buffers/line
drivers with separate output-enable (OE) inputs.
When OE is low, the device passes inverted data
from the A inputs to the Y outputs. When OE is high,
the outputs are in the high-impedance state.
