SN64BCT2244 General Description
The SN64BCT2244 is a noninverting octal buffer and line/MOS driver 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 SN64BCT2240 and SN64BCT2241, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical OE (active-low output-enable) inputs, and complementary OE and OE inputs. These devices feature high fan-out and improved fan-in.
When the output-enable (1OE and 2OE) inputs are low, the device transmits data from the A inputs to the Y outputs. When 1OE and 2OE are high, the outputs are in the high-impedance state. Output-enable 1OE affects only the 1Y outputs; output-enable 2OE affects only the 2Y outputs.
The outputs, which are designed to source or sink up to 12 mA, include 33-W series resistors to reduce overshoot and undershoot.
The SN64BCT2244 is characterized for operation from 40°C to 85°C and 0°C to 70°C.
