SN54LS377WB

Flip Flops Overview

The SN54LS377WB is a military-grade D-type flip-flop manufactured by Advanced Micro Devices. It contains eight independent positive-edge-triggered D flip-flops with clock and clear inputs, implemented in TTL technology. The device operates at a nominal supply voltage of 5 V and features a ceramic chip carrier package (CQCC20) with 20 terminals. It is designed for extended temperature ranges from -55 °C to 125 °C and meets MIL-STD-883 Class B (Modified) screening requirements.

Flip Flops Feature Summary

• Contains eight independent positive-edge-triggered D flip-flops
• Military-grade construction using ceramic packaging
• Operates within an extended industrial temperature range

Flip Flops Applications

• Military aerospace data storage systems
• High-reliability digital logic circuits
• Harsh environment signal processing registers

Flip Flops Procurement Notes

Verify the specific suffix 'WB' against official AMD documentation to confirm exact pinout and screening level. Ensure compliance with MIL-STD-883 Class B (Modified) requirements if specified for your application. Confirm that the ceramic package matches your board layout constraints. Check for RoHS non-compliance status as indicated for similar LS series parts. Validate supplier authorization for military-grade components.

Flip Flops Selection Notes

Select this component when eight synchronized D-type latches are required in a single package for critical applications. The SN54LS377WB is suitable for designs demanding high noise immunity and stability under extreme thermal conditions. Consider the ceramic package size and weight limitations during mechanical integration. Ensure the system power supply provides stable 5 V operation within specified tolerances.

Flip Flops Part Context

This part belongs to the SN54LS377 family of octal D-type flip-flops. Similar variants include the SN54LS377LB and SN54LS377F883B, which share identical logical functionality but differ in package type and material. All variants utilize standard TTL logic levels and positive-edge triggering mechanisms for consistent digital state management across the product line.

Flip Flops Replacement Considerations

Cross-reference with SN54LS377LB or SN54LS377F883B for functional equivalence. Verify package compatibility before substitution. Ensure military screening levels meet project specifications.
