Product Summary
The SN74HCT245NSR octal bus transceiver is designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. The SN74HCT245NSR allows 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 direction-control (DIR) input. The output-enable (OE) input of SN74HCT245NSR can be used to disable the device so that the buses are effectively isolated.
