description

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 upon the logic level at the

direction-control (DIR) input. The output enable

(OE)inputcanbeusedtodisablethedevicesothe

buses are effectively isolated.

The SN74F245 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.
