Description for the SN74ALS1645A
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 level at the direction-control
(DIR) input. The output-enable (
) input can be used to disable the device so that the
buses are effectively isolated. The SN74ALS1640A features inverting
logic, while the SN74ALS1645A features noninverting logic.
The SN74ALS1640A and SN74ALS1645A are characterized for operation from 0°C to 70°C.
