description/ordering information

These octal bus transceivers are designed for

asynchronous two-way communication between

data buses. The control-function implementation

minimizes external timing requirements.

GND

SN54HCT245 . . . FK PACKAGE

(TOP VIEW)

The ’HCT245 devices allow data transmission

from the Abus 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

that the buses are effectively isolated.
