description

The ’ABTH16244 devices 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 active-low output-enable (OE)

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.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

The SN54ABTH16244 is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74ABTH16244 is characterized for operation from –40°C to 85°C.
