74LS245 Datasheet Octal Bus Transceivers

Manufacturer: Texas Instruments

General Description

These octal bus transceivers are designed for asynchronous two-way communication between data buses.

The control-function implementation minimizes external timing requirements.

The SNx4LS245 devices allow data transmission 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.
