SN74ALS1245A General Description
These octal bus transceivers are designed for asynchronous two-way communication between data buses. These devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the directioncontrol (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are effectively isolated.
The SN54ALS1245A is characterized for operation over the full military temperature range of 55 to 125. The SN74ALS1245A is characterized for operation from 0 to 70.
