The 'AHC16244 devices are 16-bit buffers and line drivers designed specifically to improve 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. They 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.
The SN54AHC16244 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74AHC16244 is characterized for operation from -40°C to 85°C
