Protection

† 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.

‡ Signaling rate by TIA/EIA-485-A definition restrict transition times

to 30% of the bit length, and much higher signaling rates may be

achieved without this requirement as displayed in the TYPICAL

CHARACTERISTICS of this device.
