SN74ALS1645ADW

八路总线收发器与3态输出 OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS

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 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.
