The SN54ABT16244 and SN74ABT16244A are 16-bit
buffers and line drivers designed specifically to
improve both the performance and density of 3-state
memory

drivers,
clock
drivers,
and
bus-oriented

and
transmitters.
These
devices can be used as four 4-bit buffers, two 8-bit
buffers, or one 16-bit buffer. These devices provide

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.
