description

These octal bus transceivers are designed  
specifically for low-voltage (3.3-V) V operation,  
CC  
but with the capability to provide a TTL interface  
to a 5-V system environment.  
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 upon 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.  
The SN74LVTZ245 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 SN54LVTZ245 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74LVTZ245 is characterized for operation from –40°C to 85°C.
