SNJ54BCT374J

Flip Flops Overview

The SNJ54BCT374J is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a 20-CDIP package and supports through-hole mounting. It is designed for military-grade applications with an extended operating temperature range from -55°C to +125°C. The component includes eight input lines and eight output lines, functioning as a single circuit unit.

Flip Flops Feature Summary

• Octal D-type edge-triggered flip-flop architecture
• Three-state output capability for bus driving
• Military-grade reliability with wide temperature tolerance

Flip Flops Applications

• Military aerospace systems requiring high reliability
• Industrial control logic interfaces

Flip Flops Procurement Notes

Verify availability status carefully as this part may be subject to limited supply or special factory orders. Confirm the specific ordering suffix matches the required package and temperature grade. Ensure compatibility with existing system voltage levels and interface requirements before procurement. Check for alternative lead times if standard stock is unavailable.

Flip Flops Selection Notes

Select this component when designing systems that require robust, edge-triggered data storage with high noise immunity. The ACT/BCT series offers faster switching speeds compared to older LS families. Consider the 20-CDIP package constraints for PCB layout and thermal management. Verify that the three-state outputs align with the bus architecture requirements of the target application.

Flip Flops Part Context

This part belongs to the SN54/74BCT family, which combines the speed of AC logic with the compatibility of BCT standards. It serves as a digital storage element within complex logic circuits. The SNJ prefix indicates a military-grade version, ensuring performance under extreme environmental conditions. It is distinct from latch-based variants like the 373 series.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other SN54BCT374 variants only if pinout and electrical specifications match exactly. Verify that any replacement maintains the same military temperature rating and package type.
