(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 AM26C32is 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 AM26C32devices 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 AM26C32is characterized for operation over the extended temperature range of –55°C to 125°C.

(1)Stresses beyond those listed under "absolute maximum ratings"may cause permanent damage to the device.These are stress ratings only,and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions"is not implied.Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)All voltage values,except differential output voltage,V OD ,are with respect to network GND.Currents into the device are positive and currents out of the device are negative.

(3)Maximum power dissipation is a function of T J (max),θJA ,and T A .The maximum allowable power dissipation at any allowable ambient temperature is P D =(T J (max)–T A )/θJA .Operating at the absolute maximum T J of 150°C can affect reliability.(4)

The package thermal impedance is calculated in accordance with JESD 51-7.
