3 Description

The SNx4HCT245 octal bus transceivers

are designed for asynchronous two-way

communication between data buses. The controlfunction

implementation minimizes external timing

requirements.

The SNx4HCT245 devices allow data transmission

from the A bus to the B bus or from the B bus to the

A bus, depending upon the logic level at the directioncontrol

(DIR) input. The output-enable ( OE) input can

be used to disable the device so that the buses are

effectively isolated.
