SNJ54AS240AJ

Overview

The SNJ54AS240AJ is an octal buffer/driver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features two active-low output-enable inputs. The device utilizes AS-series technology for high-speed performance, providing symmetrical propagation delays. It is housed in a 20-pin ceramic dual in-line package (CDIP) designed for military and defense applications.

Feature Summary

• Octal configuration provides eight independent buffered channels
• Three-state outputs allow direct connection to bus lines
• Active-low output enable controls data flow direction
• Military-grade construction ensures reliability in extreme environments

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented receivers
• Bus-oriented transmitters

Procurement Notes

Verify the specific ordering suffix 'AJ' corresponds to the CDIP package variant. Confirm that the component meets MIL-PRF-38535 requirements if military qualification is necessary. Check for RoHS compliance status as indicated in the packaging addendum. Ensure the supplier provides traceability documentation consistent with aerospace or defense procurement standards.

Selection Notes

Select this component when high-speed buffering is required for bus architectures. The AS series offers faster switching characteristics compared to ALS variants. Verify that the 3-state output capability matches the system's bus isolation requirements. Consider the thermal management needs associated with the ceramic package in enclosed military enclosures.

Part Context

This part belongs to the SN54AS240A family of octal buffers/drivers. It shares functional compatibility with other devices in the ALS and AS logic families. The SNJ prefix indicates a military-grade version produced under strict quality control standards. It serves as a critical interface component in digital systems requiring high fan-out and low loading.
