SNJ54LS273W

Flip Flops Overview

The SNJ54LS273W is an octal D-type flip-flop with a clear input, designed for space-rated applications. It features eight independent D-type flip-flops, each equipped with a positive-edge-triggered clock and an asynchronous clear. The device utilizes Low-power Schottky (LS) TTL technology and provides three-state outputs for bus-oriented designs. It operates within a supply voltage range of 4.75 V to 5.25 V, with a maximum propagation delay of 27 ns at nominal voltage. The component supports a maximum operating frequency of 35 MHz and functions across an extended temperature range of -55°C to 125°C.

Flip Flops Procurement Notes

Verify the complete part number including the suffix to confirm the specific package variant and qualification level. Ensure the procurement source provides traceability documentation required for space-rated components. Confirm that the received units match the specified LS technology family and ceramic package type. Validate compliance with relevant military or aerospace standards before integration into critical systems.

Flip Flops Selection Notes

Select this component when eight-bit parallel data registration with bus-compatible outputs is required in harsh environments. The LS series offers a balance of speed and power consumption suitable for battery-constrained or thermally limited space platforms. Consider the three-state capability if multiple devices share a common data bus. Verify that the operating temperature range meets the specific environmental conditions of the target application.
