SNJ54ALS564BJ

Flip Flops Overview

The SNJ54ALS564BJ is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features three-state outputs and is housed in a 20-lead ceramic dual in-line package (CDIP). The device operates within a supply voltage range of 4.5 V to 5.5 V. It supports a wide operating temperature range from -55°C to +125°C, suitable for military and aerospace applications.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops
• Three-state outputs enabling direct bus line connections without additional interface logic
• Ceramic dual in-line package construction designed for high reliability in extreme environments

Flip Flops Applications

• Military and aerospace digital systems requiring radiation-hardened or high-reliability components
• High-speed data storage registers in professional computing architectures
• Industrial control systems operating under extreme temperature conditions

Flip Flops Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and temperature grade. Ensure compatibility with existing board layouts for 20-lead CDIP footprints. Confirm that the component meets all required environmental standards for the intended deployment environment before integration.

Flip Flops Selection Notes

Select this component when designing systems requiring octal storage with high-speed performance and robust environmental tolerance. The ALS series offers improved speed-power product compared to standard TTL. Verify that the input logic levels are compatible with the driving circuitry and that the three-state outputs meet the load requirements of the destination buses.

Flip Flops Part Context

This part belongs to the SN54/74ALS564 family of octal D-type flip-flops. The 'SNJ' prefix indicates a military-grade specification with ceramic packaging. It complements other ALS logic devices by providing high-density storage capabilities while maintaining fast switching speeds suitable for complex digital signal processing tasks.

Flip Flops Replacement Considerations

Direct pin-compatible alternatives include the SN54ALS564BQ and SN54ALS564BK. Verify that substitute parts maintain the same ceramic package dimensions and electrical characteristics. Cross-reference datasheets to ensure equivalent propagation delays and output drive strengths.
