Frequently Asked Questions
What logic family is the SNJ54AHCT02J and what makes it different from standard CMOS?
The SNJ54AHCT02J is part of the AHCT (Advanced High-speed CMOS with TTL-compatible inputs) logic family. Unlike standard HC CMOS which requires CMOS input levels (typically VCC/2), AHCT devices accept TTL input voltage levels (0.8V low, 2.0V high), making them directly compatible with legacy TTL and mixed-voltage digital systems while delivering CMOS-level output voltage swings.
How many NOR gates are in the SNJ54AHCT02J and what is their configuration?
The SNJ54AHCT02J contains four independent 2-input NOR gates in a single 14-pin package. Each gate operates independently with its own two inputs and one output, and they all share the same VCC and GND supply pins. The positive NOR function outputs a logic high only when both inputs are simultaneously at logic low, following standard positive logic convention.
What package and temperature range does the SNJ54AHCT02J use?
The SNJ54AHCT02J is housed in a 14-pin ceramic dual in-line package (CDIP) with JESD-30 code R-GDIP-T14, rated for the military temperature range of -55°C to +125°C. The ceramic package provides hermetic sealing against moisture and corrosive environments, making it suitable for long-service defense, aerospace, and high-reliability industrial programs.
Is the SNJ54AHCT02J RoHS compliant and in production?
Yes, the SNJ54AHCT02J carries a Pbfree Code of Yes indicating lead-free construction and RoHS compliance. The YTEOL value of 15 indicates active production is expected for approximately 15 more years, ensuring supply continuity for long-lifecycle military programs. The device is available from Texas Instruments in the SNJ54 military-qualified series.
