OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS

hese octal Bus Transceivers SN54ALS245A SN54AS245 SN74ALS245A SN74AS245 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 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. The -1 version of the SN74ALS245A is identical to the standard version, except that the recommended maximum IOL is increased to 48 mA. There is no -1 version of the SN54ALS245A By Texas Instruments
