Frequently Asked Questions
What is the function of the SNJ54166J?
The SNJ54166J is an 8-bit parallel-in serial-out (PISO) shift register that loads 8 parallel data bits simultaneously and shifts them out serially on subsequent clock pulses, enabling conversion from parallel to serial data format.
What does the clock inhibit feature do on the SNJ54166J?
The clock inhibit input stops the shift register from advancing on clock edges when asserted, allowing the current 8-bit state to be held without resetting the register, useful for controlled serial transmission timing.
What temperature range is the SNJ54166J rated for?
The SNJ54166J is a military-grade device rated from -55°C to 125°C, making it suitable for aerospace, defense, and industrial applications requiring operation across extreme temperature ranges.
What package does the SNJ54166J come in?
The device is housed in a 16-pin ceramic dual-in-line package (CDIP), offering the hermetic sealing and mechanical durability required for long-term reliability in military-qualified electronic systems.
