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°C to 125°C. The SN74ALS1245A is

characterized for operation from 0°C to 70°C.
