Frequently Asked Questions
What is the maximum clock frequency of the SNJ54AS175BJ?
The SNJ54AS175BJ operates at a maximum clock frequency of 100 MHz (100,000,000 Hz), which is characteristic of the Advanced Schottky (AS) logic family's high-speed bipolar process. This makes it suitable for fast digital sequential circuits including high-speed registers, counters, and synchronization elements in military and aerospace computing systems.
What is the operating temperature range of the SNJ54AS175BJ?
The SNJ54AS175BJ is rated for military-standard operation from -55°C to 125°C. This extended temperature range qualifies the device for aerospace avionics, defense electronics, and harsh industrial environments where commercial-grade ICs rated to only 70°C or 85°C would fail to operate reliably.
How many flip-flops are in the SNJ54AS175BJ and what is the package?
The SNJ54AS175BJ contains four independent D-type flip-flops (quadruple configuration) in a 16-pin ceramic dual-in-line package (CDIP). The ceramic package provides superior moisture resistance and thermal stability compared to plastic DIP packages, which is critical for long-life military and aerospace applications.
Does the SNJ54AS175BJ have a clear function and how does it operate?
Yes, the SNJ54AS175BJ includes an asynchronous clear input that simultaneously resets all four flip-flop outputs to logic LOW, independent of the clock signal. This synchronous clear capability is essential for system initialization sequences and fault-recovery routines in safety-critical embedded control and avionics applications.
