On All Other Products, Production Processing Does Not Necessarily Include Testing of All Parameters. 2 Applications Servers PCs and Notebooks Network Switches Wearable Health and Fitness Devices Telecom Infrastructures Electronic Points of Sale 1 DIR 3 Description These octal bus transceivers are designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. The devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on 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.
