TLC2254IDRG4 Equivalent & Substitute Parts

Part Overview

The TLC2254IDRG4 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 4.4 V to 16 V. The TLC2254IDRG4 is part of Texas Instruments' LinCMOS™ series and is currently discontinued at DiGi Electronics. Due to its discontinued status, identifying equivalent substitute parts is essential for design continuity and procurement planning. The TLC2254IDR serves as the primary active alternative, offering identical electrical and mechanical specifications with improved availability.

• Slew Rate: 0.12 V/µs
• Gain Bandwidth Product: 210 kHz
• Current - Input Bias: 1 pA
• Voltage - Input Offset: 200 µV
• Current - Supply: 160 µA (x4 Channels)
• Current - Output / Channel: 50 mA
• Voltage - Supply Span: 4.4 V to 16 V
• Operating Temperature Range: -40°C to 125°C

Mechanical Parameter Equivalence:

• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 14-SOIC

Compliance Equivalence:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The TLC2254IDR meets all substitution criteria and is classified as the manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The TLC2254IDR is the direct substitute for the discontinued TLC2254IDRG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, mechanical dimensions, and compliance certifications. The primary distinction is product status: the TLC2254IDRG4 is discontinued, while the TLC2254IDR maintains active status with significantly higher inventory availability (21,005 units in stock versus 947 units for the main part).

From a compliance perspective, both parts satisfy ROHS3 requirements, maintain REACH unaffected status, and carry identical moisture sensitivity ratings. The TLC2254IDR is available in standard packaging formats (Cut Tape and Digi-Reel®), ensuring compatibility with automated assembly processes.

For new designs or procurement of replacement stock, the TLC2254IDR is the appropriate selection. Existing designs using the TLC2254IDRG4 can transition to the TLC2254IDR without circuit modification, as all functional and mechanical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the TLC2254IDR be used as a direct replacement for the TLC2254IDRG4?

A: Yes. The TLC2254IDR is electrically and mechanically identical to the TLC2254IDRG4.
