† _{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
Each data selector/multiplexer contains inverters and drivers to supply full binary decoding data selection to the
AND-OR gates. Separate output-control inputs are provided for each of the two 4-line sections.
The 3-state outputs can interface with and drive data lines of bus-organized systems. With all but one of the
common outputs disabled (in the high-impedance state), the low impedance of the single enabled output drives
the bus line to a high or low logic level. Each output has its own output-enable (OE) input. The outputs are
disabled when their respective OE is high.
