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  
The SN74AC245 octal bus transceiver is designed for asynchronous two-way communication between data  
buses. The control-function implementation minimizes external timing requirements.  
When the output-enable (OE) is low, the device passes noninverted data from the A bus to the B bus or from  
the B bus to the A bus, depending on the logic level at the direction control (DIR) input. A high on OE disables  
the device so that the buses are effectively isolated.  
To ensure the high-impedance state during power up or power down, OE should be tied to V  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
