(1) 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.

The AM26C31 is a differential line driver with complementary outputs, designed to meet the requirements of

TIA/EIA -422-B and ITU (formerly CCITT). The 3-state outputs have high-current capability for driving balanced

lines, such as twisted-pair or parallel-wire transmission lines, and they provide the high-impedance state in the

power-off condition. The enable functions are common to all four drivers and offer the choice of an active-high

(G) or active-low ( G) enable input. BiCMOS circuitry reduces power consumption without sacrificing speed.

The AM26C31 is characterized for operation over extended temperature range of – 55 ° C to 125 ° C.
