SN74ABT244A General Description
These octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. Together with the SN54ABT240, SN74ABT240A, SN54ABT241, and SN74ABT241A, 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 SN54ABT244 and SN74ABT244A are organized as two 4-bit buffers/line drivers with separate OE inputs.When OE is low, the devices pass noninverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.
