SN54AS645 - Octal Bus Transceivers

Download the SN54AS645 datasheet PDF (SN54ALS645A included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for octal bus transceivers.

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.
