Using 25-mil Center-to-Center SpacingsThe SN54ABT16244 and SN74ABT16244A are 16-bit
buffers and line drivers designed specifically to
improve both the performance and densityof 3-state
memory address drivers, clock drivers, and
bus-oriented receivers and transmitters. These
devices can be used as four 4-bit buffers, two 8-bit
buffers,or one 16-bit buffer. These devices provide
true outputs and symmetrical OE (active-low
output-enable) inputs.
resistor; the minimum valueof the resistoris determined the current-sinking capabilityof the driver.
The SN54ABT16244is characterized for operation over the full military temperature rangeof –55°Cto 125°C.
The SN74ABT16244Ais characterized for operation from –40°Cto 85°C.
