SN54ALS640BJ Description

Short technical summary and product information.

The Texas Instruments SN54ALS640BJ is an octal bus transceiver designed for asynchronous two-way communication between data buses. It transmits data from the A bus to the B bus or vice versa, controlled by the direction-control (DIR) input. The output-enable input allows for disabling the device, effectively isolating the buses.

 

This transceiver operates with TTL input and output types and boasts balanced outputs, high speed with a typical propagation delay (tpd) between 10-50ns, and over-voltage tolerant inputs. It is rated for military applications and operates across a wide temperature range of -55°C to 125°C.

 

The SN54ALS640BJ is available in a 20-pin CDIP (J) package. Other package options include Plastic Small-Outline (DW), Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 300-mil DIPs. This component is part of the ALS technology family.

 

Key electrical specifications include 8 channels, a maximum IOL of 12 mA, and a maximum IOH of -12 mA. These characteristics make it suitable for various interfacing applications requiring reliable bidirectional data transfer.
