The SN54LS640J from Texas Instruments is an octal bus transceiver, part of the LS technology family. It is designed for asynchronous two-way communication between data buses, allowing data transmission from the A bus to the B bus or vice versa, controlled by the DIR input. The enable input (G) can disable the device, effectively isolating the buses.
This transceiver operates with TTL input and output types and supports 8 channels. It has a maximum output current of 12 mA for both high and low states. The device is characterized by its high speed, with propagation delays typically between 10-50 ns. It is rated for military applications and operates across a wide temperature range of -55°C to 125°C.
The SN54LS640J is available in CDIP and LCCC package types. Its balanced outputs and high-speed performance make it suitable for various interfacing applications where reliable data transfer between buses is required.
