Component qualification in accordance with JEDEC and industry  
standards to ensure reliable operation over an extended  
temperature range. This includes, but is not limited to, Highly  
Accelerated Stress Test (HAST) or biased 85/85, temperature  
cycle, autoclave or unbiased HAST, electromigration, bond  
intermetallic life, and mold compound life. Such qualification  
testing should not be viewed as justifying use of this component  
beyond specified performance and environmental limits.

description/ordering information  
This octal buffer and line driver is designed specifically to improve both the performance and density of 3-state  
memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The SN74HCT244 device  
is organized as two 4-bit buffers/drivers, with separate output-enable (OE) inputs. When OE is low, the device  
passes noninverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the  
high-impedance state.
