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


Description

These octal bus transceivers of the SN74BCT245 are designed for asynchronous communication between data buses. The devices transmit data from the A bus to the B bus or from the B bus to the A bus depending upon the 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.


The SN74BCT245 is available in TI's shrink small-outline package (DB), which provides the same I/O pin count and functionality of standard small-outline packages in less than half the printed-circuit-board area.


The SN74BCT245 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74BCT245 is characterized for operation from 0°C to 70°C.
