These octal bus transceivers 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 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.

When V  
is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.  
CC  
However, to ensure the high-impedance state above 2.1 V, OE should be tied to V  
the minimum value of the resistor is determined by the current-sinking capability of the driver.

This device is fully specified for hot-insertion applications using I and power-up 3-state. The I circuitry  
off  
off  
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.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.  
The SN54ABTH245 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74ABTH245 is characterized for operation from –40°C to 85°C.
