Frequently Asked Questions
What is the maximum clock frequency of the SNJ54AS174J?
The SNJ54AS174J supports a maximum clock frequency of 100 MHz, enabled by the Advanced Schottky (AS) bipolar technology which provides faster propagation delays than standard TTL, making it suitable for high-speed military data bus and pipeline register applications.
What is the operating temperature range of the SNJ54AS174J?
The SNJ54AS174J is rated for military-grade operation from -55°C to 125°C, qualified for use in avionics, shipboard electronics, and ground vehicle systems where commercial-grade ICs cannot guarantee reliable operation over the full temperature range.
How does the clear function work on the SNJ54AS174J?
The SNJ54AS174J has an active-low asynchronous clear (CLR) input that immediately resets all six flip-flop outputs to LOW regardless of the clock state, enabling fast system initialization or global reset in synchronous digital designs.
What logic family does the SNJ54AS174J belong to, and is it RoHS compliant?
The SNJ54AS174J belongs to the Advanced Schottky (AS) bipolar TTL family and carries a RoHS-compliant (JESD-609 Code e0) designation, meeting lead-free requirements while being packaged in the hermetic ceramic DIP format required by military specifications.
