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 SN54ABT2240,
SN74ABT2240A, and 'ABT2241, 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. SN54ABT2240 feature high fan-out and improved fan-in.

The outputs of SN54ABT2240, which are designed to sink up to 12 mA, include equivalent 25-W  series resistors to reduce overshoot and undershoot.
