Frequently Asked Questions
What type of flip-flop is the SNJ54ACT74J?
The SNJ54ACT74J contains two positive-edge-triggered D-type flip-flops. Each flip-flop captures the logic level at its D input on the rising edge of the clock signal and holds it at the Q output. Individual asynchronous SET and CLEAR inputs allow overriding the stored state regardless of the clock state.
What logic family does the SNJ54ACT74J belong to?
The SNJ54ACT74J belongs to the ACT (Advanced CMOS Technology with TTL-compatible inputs) logic family. It combines the low-power dissipation of CMOS with TTL-compatible input threshold levels, enabling direct interfacing with TTL-output devices while consuming significantly less power than equivalent LSTTL flip-flops.
What temperature range is the SNJ54ACT74J rated for?
The SNJ54ACT74J is rated for the military temperature range of -55°C to 125°C. The hermetic ceramic DIP package provides protection against moisture, contamination, and thermal stress, making it suitable for aerospace, defense, and harsh industrial environments.
What is the maximum clock frequency of the SNJ54ACT74J?
The SNJ54ACT74J supports a maximum clock frequency of 85MHz, which is adequate for many digital control, data sampling, and state machine applications in military and industrial embedded systems requiring reliable edge-triggered data storage at moderate clock speeds.
