Its synchronous operation eliminates ripple delays, making it suitable for timing-critical paths in programmable controllers, test equipment, and avionics sequencers where clock-to-output predictability matters more than raw gate count. ## Active lifecycle — no LTB pressure on this BOM line The RoHS non-compliant designation matters for EU RoHS and similar regulated markets — verify your exemption coverage or plan for a compliant alternative if your assembly line requires lead-free materials.","metaTitle":"SNJ54AS169AJ Binary Counter, Active, RoHS Non-Compliant","metaDescription":"SNJ54AS169AJ binary counter from Texas Instruments.

The CY74FCT191ATSOC is a functionally similar synchronous binary counter from the 74FCT family, but it is surface-mount, operates from a 4.75 V supply, and has a commercial temperature range of -40°C to 85°C — verify pin compatibility and timing before substituting."},{"question":"How does SNJ54AS169AJ compare to SN74AS169AN?","answer":"The SNJ54AS169AJ is the military-temperature-range version of the standard SN74AS169AN. The 'J' suffix indicates a ceramic DIP package and -55°C to 125°C operation, while the commercial-grade SN74AS169AN typically uses a plastic DIP rated 0°C to 70°C. Function and pinout are identical; the selection depends on your environmental requirements and procurement channel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SNJ54AS169AJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SNJ54AS169AJ when reusing this data.
