SNJ54AS174J

Flip Flops Overview

The SNJ54AS174J is a military-grade hex D-type flip-flop manufactured by Texas Instruments. It features positive-edge triggering and an asynchronous master reset input. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 100 MHz. Propagation delay is specified at 10ns under standard load conditions. It utilizes Schottky bipolar technology for high-speed performance and is housed in a 16-lead ceramic dual in-line package (CDIP) designed for -55°C to 125°C operation.

Flip Flops Procurement Notes

Verify the authenticity of the SNJ54AS174J through authorized channels, as it is a specialized military component. Confirm that the package matches the 16-lead CDIP specification and check for any specific lot traceability requirements mandated by defense contracts. Ensure compliance with export control classifications such as EAR99 before finalizing procurement.

Flip Flops Selection Notes

Select the SNJ54AS174J when high-speed logic switching is required in harsh environments. Its Schottky technology offers superior speed over standard LS or ALS families. Consider the CDIP package for through-hole mounting in ruggedized PCBs. Verify that the 100 MHz clock limit and 10ns propagation delay meet the system's timing constraints.

Flip Flops Part Context
