SN74HC640 - Octal Bus Transceivers With 3-State Outputs

Updated : 2020-01-09 14:36:34
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 upon the level at the direction-control (DIR) input. The output-enable (OE)\ input can be used to disable the device so the buses are effectively isolated.
