The Texas Instruments SN54LS640 is an octal bus transceiver designed for asynchronous two-way communication between data buses. It facilitates data transmission from the A bus to the B bus or vice versa, controlled by the direction control (DIR) input. The enable input (G) allows for disabling the device, effectively isolating the buses.
This transceiver features 3-state outputs and hysteresis at the bus inputs, which improves noise margins. It is characterized for operation over the full military temperature range of -55°C to 125°C. The device comes in a 20-pin CDIP package.
Key specifications include an operating temperature range of -55 to 125°C, octal bus transceiver functionality, 3-state logic, and open-collector outputs. The recommended maximum I OL is 48 mA.
