description
This octal buffer/line driver is designed specifically
to improve both the performance and density of
3-state memory address drivers, clock drivers,
and bus-oriented receivers and transmitters. This
device
provides
inverting
symmetrical active-low output-enable (OE)
inputs. This device features high fan-out and
improved fan-in.
outputs
and
The 74AC11240 is organized as two 4-bit buffers/line drivers with separate 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.
The 74AC11240 is characterized for operation from –40
°
C to 85
°
C.
