TLV2254QDR Equivalent & Substitute Parts

Part Overview

The TLV2254QDR is a general-purpose operational amplifier featuring four independent circuits in a 14-SOIC surface mount package. This device is designed for rail-to-rail output applications with low input bias current and operates across a wide supply voltage range of 2.7V to 8V. The TLV2254QDR is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The substitute part maintains identical electrical and mechanical specifications while offering improved availability and active product status.

The TLV2254IDR differs from the TLV2254QDR only in product status (active versus obsolete) and packaging format (Tape & Reel versus standard packaging), with no electrical or mechanical parameter variations.

Parameter Comparison

Engineering Selection Recommendations

The TLV2254IDR is the direct equivalent substitute for the TLV2254QDR. All electrical parameters, mechanical specifications, and environmental compliance certifications are identical between the two parts. The primary distinction is product lifecycle status: the TLV2254QDR is obsolete, while the TLV2254IDR maintains active product status with Texas Instruments.

Selection of the TLV2254IDR is appropriate for:

• New design implementations requiring a four-channel general-purpose operational amplifier
• Production continuity for existing designs currently using the TLV2254QDR
• Applications requiring ROHS3 compliance and automotive-grade reliability
• Systems operating within the -40°C to 125°C temperature range
• Circuits with supply voltages between 2.7V and 8V

The TLV2254IDR is supplied in Tape & Reel packaging format, suitable for automated assembly processes. No circuit redesign or PCB layout modification is required when transitioning from TLV2254QDR to TLV2254IDR.
