SCBS017C - SEPTEMBER 1988 - REVISED NOVEMBER 1993

features

• State-of-the-Art BiCMOS Design Significantly Reduces I_CCZ
• Output Ports Have Equivalent 33- Series Resistors, So No External Resistors Are Required
• 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
• Package Options Include Plastic Small-Outline (DW) Packages, Ceramic Chip Carriers (FK) and Flatpacks (W), andStandard Plastic and Ceramic 300-mil DIPs (J, N)

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. Taken together with the ´BCT2240 and SN74BCT2241, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical active-low output-enable () inputs, and complementary OE and inputs. These devices feature high fan-out and improved fan-in.

The outputs, which are designed to source or sink up to 12 mA, include 33-series resistors to reduce overshoot and undershoot.

The SN54BCT2244 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74BCT2244 is characterized for operation from 0°C to 70°C.
