description
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 V
CC
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.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51.

retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
