SN74ABT240A
SN74ABT240A is OCTAL BUFFERS/DRIVERS manufactured by Texas Instruments.
tion
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 SN54ABT241,
SN74ABT241A,
SN54ABT244, and
SN74ABT244A, these devices provide the choice of selected binations of inverting and noninverting outputs, symmetrical active-low output-enable (OE) inputs, and plementary
OE and OE inputs.
The SN54ABT240 and SN74ABT240A are organized as two 4-bit buffers/line drivers with separate OE inputs. When OE is low, the devices pass inverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.
