SN74ALS1645AN
Octal Bus Transceivers With 3-State Outputs
Small-Outline (DW) Packages and Standard
Plastic (N) 300-mil DIPs
descriptionThese 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 (OE) 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.
