description  
These octal bus transceivers are designed specifically for low-voltage (3.3-V) V  
capability to provide a TTL interface to a 5-V system environment.  
operation, but with the  
CC  
These devices are designed for asynchronous communication between data buses. They 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 devices so the buses are effectively isolated.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.  
When V is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down.  
CC  
However, to ensure the high-impedance state above 1.5 V, OE should be tied to V  
through a pullup resistor;  
CC  
the minimum value of the resistor is determined by the current-sinking capability of the driver.  
These devices are 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 devices when they are 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.  
The SN54LVTH245A is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74LVTH245A is characterized for operation from –40°C to 85°C.
