Texas Instruments High-Performance Analog Drivers, Receivers, Transceivers SNJ54F623FK

The SNJ54F623FK is an octal bus transceiver designed for asynchronous communication between data buses. It features a dual-enable configuration that allows for data transmission from either the A bus to the B bus or vice versa, depending on the logic levels at the output enable inputs (OEAB and OEBA). This configuration also enables the device to store data by simultaneously enabling both outputs, maintaining the last state of the bus lines when all other data sources are high impedance. This device operates over a military temperature range of -55¬8C to 125¬8C, making it suitable for harsh environments. The SNJ54F623FK is characterized by a supply voltage range of 4.5V to 5.5V and supports high and low output currents of up to 40 mA and 96 mA for the A and B ports, respectively. The product is available in a LCCC package and is marked as obsolete, indicating it may no longer be in production. Engineers should consider this device for applications requiring robust data bus communication in extreme temperature conditions.
