SN74BCT374DBR

Flip Flops Overview

The SN74BCT374DBR is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features eight independent D-type flip-flops with three-state outputs, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels. Key electrical specifications include a propagation delay of 9.1 ns, a high-level output current of -15 mA, and a low-level output current of 64 mA. The component is designed for surface-mount installation and functions reliably across a temperature range from 0°C to +70°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops
• Three-state outputs enabling direct bus-driven connections
• TTL-compatible input logic levels for seamless integration
• High drive capability with significant low-level output current

Flip Flops Applications

• Registering data on microprocessor buses
• Buffering memory address lines
• General-purpose parallel-to-serial conversion circuits
• I/O port expansion in embedded systems

Flip Flops Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SOIC-20 package and tape-and-reel packaging format. Confirm that the operating voltage requirements align strictly with the 4.5 V to 5.5 V range. Ensure thermal management meets the specified junction temperature limits for the intended application environment. Cross-reference the manufacturer's latest datasheet for any pinout or electrical characteristic updates.

Flip Flops Selection Notes

Select this component when TTL compatibility is required alongside high drive strength. The BCT series offers faster switching speeds compared to standard LS logic while maintaining CMOS power efficiency. Consider the SOIC-20 package dimensions for PCB layout constraints. Evaluate the need for three-state outputs if bus sharing is necessary in the system design.

Flip Flops Part Context

This part belongs to the SN74BCT series, which combines the speed of Schottky TTL with the low power consumption of CMOS technology. It is functionally compatible with other octal flip-flops in the 74xx family but optimized for higher performance applications. The DBR suffix indicates a specific reel-based packaging option suitable for automated assembly processes.

Flip Flops Replacement Considerations

SN74BCT374DW (SOIC-20 tube) and SN74BCT374N (PDIP-20) are confirmed substitutes within the same family.
