SNJ54BCT374W

Flip Flops Overview

The SNJ54BCT374W is an octal edge-triggered D-type flip-flop featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum frequency of 150 MHz. The device includes eight bits with a shared clock and output enable pin, utilizing TTL input levels. It is housed in a 20-lead ceramic flatpack (CFP) package designed for military-grade reliability across an extended temperature range of -55°C to +125°C.

Flip Flops Feature Summary

• Contains eight channels of D-type flip-flops with a shared clock and output enable pin
• Features three-state outputs for bus-oriented memory mapping and driving
• Supports TTL-compatible input levels for direct interfacing

Flip Flops Applications

• Military-grade digital systems requiring high reliability
• Bus-oriented memory register applications
• Clock buffers and drivers in harsh environments

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range, as variations exist within the BCT series. Ensure compatibility with existing PCB footprints for the 20-lead ceramic flatpack configuration. Confirm that the procurement source provides traceability documentation suitable for defense or aerospace contracts. Check for any lead-free status discrepancies if environmental compliance is required for the specific project phase.

Flip Flops Selection Notes

Select this component when military-grade temperature stability (-55°C to +125°C) is mandatory alongside high-speed data latching capabilities. The BCT series offers faster performance than standard 74-series logic while maintaining low power consumption. Consider the ceramic flatpack package for superior thermal dissipation and mechanical robustness compared to plastic alternatives in demanding operational scenarios.

Flip Flops Part Context

This part belongs to the SNx4BCT374 family of octal edge-triggered D-type latches with three-state outputs. The 'SNJ' prefix indicates a military-grade qualification level, ensuring performance under extreme conditions. The 'BCT' designation signifies BiCMOS technology, which combines the speed of bipolar transistors with the low power of CMOS. This family serves as a high-performance alternative to standard logic families in critical applications.
