• Bidirectional Bus Transceivers in High-Density 20-Pin Packages • Low-Power Versions of ′ALS245 Series • ′ALS1245 Series Is Identical to ′ALS1645 Series • Package Options Include Plastic Small-Outline (DW) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 300-mil DIPs 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 logic level at the directioncontrol (DIR) input.
The output-enable (OE) input can be used to disable the device so the buses are effectively isolated.
The SN54ALS1245A is characteriz...
