Taken together with the SN64BCT2241 and SN64BCT2244, these devices provide the choice of selected combinations of inverting 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 Y outputs reflect the inverse of the data present at the A inputs. 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-Ω series resistors to reduce overshoot and undershoot. The SN64BCT2240 is characterized for operation from − 40°C to 85°C and 0°C to 70°C.
