Frequently Asked Questions
What is the temperature range of the SNJ54ALS112AJ?
The SNJ54ALS112AJ is rated for the full military temperature range of -55°C to 125°C, meeting the requirements of MIL-spec 54-series digital logic components. This wide temperature capability ensures reliable operation in avionics, military ground vehicles, and space applications where commercial-grade components would fail due to temperature extremes.
What logic function does the SNJ54ALS112AJ perform?
The SNJ54ALS112AJ implements two independent J-K negative-edge-triggered flip-flops, each with J, K, clock, asynchronous clear (CLR), and asynchronous preset (PRE) inputs, plus complementary Q and Q-bar outputs. The J-K flip-flop is a universal sequential logic element that can be configured for toggle, set, reset, and hold operations depending on the J and K input states at the active clock edge.
What package does the SNJ54ALS112AJ use?
The SNJ54ALS112AJ is housed in a 16-pin ceramic DIP (CDIP) package, designated JESD-30 R-GDIP-T16. The ceramic DIP provides hermetic sealing that protects the die from moisture, temperature cycling, vibration, and corrosive atmospheres — all essential properties for components used in military and space-grade electronic assemblies with decades-long operational lifetimes.
What is the maximum clock frequency of the SNJ54ALS112AJ?
The SNJ54ALS112AJ supports a maximum clock frequency of 25 MHz at nominal supply voltage, which is consistent with the ALS (Advanced Low-power Schottky) TTL logic family's performance characteristics. This speed is sufficient for many sequential logic, counter, and register applications in digital control systems that do not require the higher frequencies of CMOS or ECL logic families.
