SN74BCT2414DWR

Specialty Logic Overview

The SN74BCT2414DWR is a memory decoder IC from Texas Instruments, housed in a 20-pin SOIC package. It features two independent 2-line to 4-line decoders designed for memory systems with battery backup during power failure. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum output current of 24 mA. It functions reliably across an operating temperature range of -40°C to +85°C.

Specialty Logic Feature Summary

• Designed specifically for memory systems requiring battery backup during power failure events
• Integrates two independent 2-line to 4-line decoding circuits on a single chip
• Includes on-chip supply voltage monitoring capabilities

Specialty Logic Applications

• Memory systems with battery backup
• Power failure protection circuits
• Address decoding in embedded storage architectures

Specialty Logic Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the active status aligns with long-term production plans, as availability may vary. Ensure the 20-SOIC footprint matches your PCB design constraints before finalizing procurement orders.

Specialty Logic Selection Notes

Select this component when designing memory subsystems that require dedicated hardware decoding under low-voltage conditions. It is suitable for applications needing isolated 2-to-4 line translation with integrated voltage supervision. Consider its BCT logic family characteristics for compatibility with existing bus structures in industrial or commercial memory modules.

Specialty Logic Part Context

This part belongs to the SN74BCT series, which combines BiCMOS technology for high-speed performance with CMOS input levels. The SN74BCT2414 variant specifically addresses memory decoding needs, distinguishing itself from standard logic decoders by including power-fail detection features essential for data integrity in backup scenarios.

Specialty Logic Replacement Considerations

Public sources indicate the SN74BCT2414DWR is obsolete. Verify if the SN74BCT2414DW (tube) or other non-reel variants are available as direct physical replacements. Check for newer generation equivalents from Texas Instruments that maintain the same pinout and functional specifications.
