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.
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 SN74HC244 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.
