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.


Description

The SN74BCT2245 octal transceiver and line/MOS driver is designed for asynchronous communication between data buses.


he device allows data transmission of the SN74BCT2245 from the A bus to the B bus or from the B bus to the A bus depending upon he logic level at the direction-control (DIR) input. The output-enable (OE) input can disable the devices so that oth buses are effectively isolated.


The B-port outputs of the SN74BCT2245, which are designed to source or sink up to 12 mA, include 33-W  series resistors to reduce overshoot and undershoot.


The SN74BCT2245 is characterized for operation from 0°C to 70°C.
