description
The SN64BCT2241 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 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.
The SN64BCT2241 features complementary output-enable (1OE and 2OE) inputs. The 1Y outputs are active
(high or low) when the active-low enable 1OE is low. When 1OE is high, the 1Y outputs are in the
high-impedance state. The 2Y outputs are active when 2OE is high and in the high-impedance state when 2OE
is low.
The outputs, which are designed to source or sink up to 12 mA, include 33-Ω series resistors to reduce overshoot
and undershoot.
The SN64BCT2241 is characterized for operation from − 40°C to 85°C and 0°C to 70°C.
