Frequently Asked Questions
What type of flip-flop is the SNJ54ALS175J and how many bits does it store?
The SNJ54ALS175J is a quadruple D-type flip-flop that stores four independent bits of data. Each flip-flop captures and latches the data present at its D input on the rising edge of the common clock signal, and all four flip-flops share a common asynchronous active-low clear (CLR) input.
What is the maximum clock frequency of the SNJ54ALS175J?
The SNJ54ALS175J supports a maximum clock frequency of 40 MHz, as specified by the Max Frequency@Nom-Sup spec. The ALS (Advanced Low-power Schottky) family uses Schottky-clamped bipolar transistors to achieve fast propagation delays while maintaining lower power consumption than standard Schottky TTL logic.
What is the operating temperature range of the SNJ54ALS175J?
The SNJ54ALS175J is rated for the full military temperature range of -55°C to 125°C. The SNJ prefix indicates it is qualified to MIL-PRF-38510 standards, making it suitable for use in military, defense, and aerospace systems requiring high-reliability digital storage elements.
What package does the SNJ54ALS175J come in and is it RoHS compliant?
The SNJ54ALS175J is housed in a 16-pin ceramic dual-in-line package (CDIP, JEDEC R-GDIP-T16), providing hermetic sealing for high-reliability environments. It carries JESD-609 code e0 (lead-free termination finish) and is marked with Pbfree Code Yes, confirming RoHS compliance.
