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
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.

3OE
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 鈥?5擄C to 125擄C.
The SN74ABT16244A is characterized for operation from 鈥?0擄C to 85擄C.
