(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.  
DESCRIPTION/ORDERING INFORMATION  
This octal bus transceiver is designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to  
provide a TTL interface to a 5-V system environment.  
This device is designed for asynchronous communication between data buses. It transmits 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. The  
output-enable (OE) input can be used to disable the device so the buses are effectively isolated.  
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. Use of pullup or  
pulldown resistors with the bus-hold circuitry is not recommended.  
This device is fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry  
disables the outputs, preventing damaging current backflow through the device when it is powered down. The  
power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,  
which prevents driver conflict.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas  
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
