description

These octal bus transceivers are designed for

The ’LV245 are designed for asynchronous

communication between data buses. The device

transmits 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 device so the buses are effectively isolated.

The SN74LV245 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 SN54LV245 is characterized for operation over the full military temperature range of −55

°C to 125°C. The

SN74LV245 is characterized for operation from −40

°C to 85°C.
