Recommendation V.10 and V.11

(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 AM26C32 is a quadruple differential line receiver for balanced or unbalanced digital data transmission. The

enable function is common to all four receivers and offers a choice of active-high or active-low input. The 3-state

outputs permit connection directly to a bus-organized system. Fail-safe design specifies that if the inputs are

open, the outputs always are high.

The AM26C32 devices are manufactured using a BiCMOS process, which is a combination of bipolar and CMOS

transistors. This process provides the high voltage and current of bipolar with the low power of CMOS to reduce

the power consumption to about one-fifth that of the standard AM26LS32, while maintaining ac and dc

performance.

The AM26C32 is characterized for operation over the extended temperature range of – 55 ° C to 125 ° C.
