SN54LS645J Description

Short technical summary and product information.

The SN54LS645J from Texas Instruments is an octal bus transceiver designed for asynchronous two-way communication between data buses. This military-rated component operates across a temperature range of -55°C to 125°C.

 

It features 8 channels with balanced outputs and high-speed performance, indicated by a typical propagation delay (tpd) between 10-50ns. The device utilizes TTL logic for both its inputs and outputs. The direction of data transmission between the A and B buses is controlled by the direction control (DIR) input, while the enable input (G) can disable the device, effectively isolating the buses.

 

Packaged in a 20-pin CDIP (J) format, the SN54LS645J is suitable for applications requiring robust data bus communication in demanding environments. Its design includes hysteresis at bus inputs to improve noise margins and offers a choice of true or inverting logic configurations.
