Description

The SN54ABT16244 and SN74ABT16244A are 16-bit buffers and line drivers designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. These SN54ABT16244 and SN74ABT16244A  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.To ensure the high-impedance state during power up or power down, OE should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.The SN54ABT16244 is characterized for operation over the full military temperature range of 55°C to 125°C.The SN74ABT16244A is characterized for operation from 40°C to 85°C.
