SN74AHC374DBR

Flip Flops Overview

The SN74AHC374DBR is an octal D-type flip-flop from the Texas Instruments AHC logic series, housed in a 20-pin SSOP package. It features positive-edge triggering and three-state outputs with non-inverting polarity. The device operates on a supply voltage range of 2 V to 5.5 V, drawing a static current of 4 µA. Key electrical parameters include a maximum propagation delay of 16.2 ns, output currents of ±8 mA, and an input capacitance of 4 pF.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit
• Positive-edge triggered clocking mechanism for precise data synchronization
• Three-state outputs allowing direct connection to bus structures without external drivers
• CMOS input structure ensuring compatibility with standard logic families

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in digital systems
• Bus buffer applications requiring tri-state isolation
• Timing delay compensation in signal paths

Flip Flops Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-20 package and tape-and-reel shipping format. Confirm RoHS compliance status matches current manufacturing standards. Ensure the operating temperature range aligns with system thermal requirements. Cross-reference the manufacturer part number against authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when an octal register with high-speed performance and low power consumption is required. The AHC series offers faster switching speeds compared to standard HC logic while maintaining CMOS input characteristics. The wide supply voltage range supports both 2.5 V and 5 V system architectures. Consider the SSOP package dimensions for PCB layout constraints and thermal dissipation needs in dense assemblies.

Flip Flops Part Context

This device belongs to the SN74AHC374 family of octal edge-triggered D-type flip-flops. It shares functional similarities with other variants like the SN74AHC374DWR (SOIC package) but differs in physical footprint. The AHC series represents an advancement over older technologies, providing improved speed and lower power consumption suitable for modern portable and high-density electronic designs.

Flip Flops Replacement Considerations

SN74AHC374DWRE4 and SN74AHC374DWRG4 are confirmed equivalent parts offering identical electrical specifications and functionality. These alternatives may differ only in manufacturing lot codes or minor packaging variations while maintaining pin compatibility.
