This octal buffer and 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. Taken together with the
SN64BCT241 and SN64BCT244, these devices provide the choice of selected combinations of inverting and
noninverting outputs, symmetrical active-low output-enable (OE) inputs, and complementary OE and OE inputs.
The SN64BCT240 is organized as two 4-bit buffers/line drivers with separate output-enable (OE) inputs. When
OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the
high-impedance state.
The SN64BCT240 is characterized for operation from –40°C to 85°C and 0°C to 70°C.
