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.

To ensure the high-impedance state during power up or power down, OE should be tied to VCC 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.
