Engineering Selection Recommendations

Primary Recommendation: TLV2464IPWR

The TLV2464IPWR is the direct manufacturer-recommended substitute for the obsolete TLV2464IPWRG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, including slew rate (1.6 V/µs), gain bandwidth product (6.4 MHz), input bias current (1.3 nA), input offset voltage (500 µV), supply current (550 µA per four channels), and output current per channel (80 mA). The TLV2464IPWR maintains the same 14-TSSOP package footprint and operates across the full industrial temperature range (-40°C to 125°C). The primary distinction is product status: TLV2464IPWR is active, ensuring long-term availability and supply chain continuity. Both parts are ROHS3 compliant with MSL 1 rating.

Secondary Recommendations by Application Profile:

For Low-Power Applications: MCP6484-E/ST or MCP6484T-E/ST (Microchip Technology) offer reduced supply current consumption (240 µA per four channels) compared to the original specification (550 µA). These parts maintain the 14-TSSOP package, rail-to-rail output, and full industrial temperature range. Trade-offs include lower output current per channel (12 mA versus 80 mA) and reduced gain bandwidth product (4 MHz versus 6.4 MHz).

For High-Speed Applications: AD8604ARUZ-REEL (Analog Devices Inc.) or MCP6494-E/ST (Microchip Technology) provide elevated slew rates (6 V/µs) and higher gain bandwidth products (8.4 MHz and 7.5 MHz respectively) compared to the original 1.6 V/µs and 6.4 MHz. Both maintain 14-TSSOP packaging, rail-to-rail output, and industrial temperature range operation. The AD8604ARUZ-REEL features CMOS architecture with exceptionally low input bias current (0.2 pA).

For General-Purpose Replacement: MCP6284T-E/ST (Microchip Technology) provides balanced performance with moderate slew rate (2.5 V/µs), gain bandwidth product (5 MHz), and supply current (450 µA per four channels). This part maintains full compatibility with the 14-TSSOP package and industrial temperature range.

Compliance and Certification Status:

All recommended substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. All parts are classified as active products with established supply chains, supporting production continuity and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the TLV2464IPWR directly replace the TLV2464IPWRG4 without circuit modification?

A: Yes. The TLV2464IPWR is the manufacturer-recommended direct substitute. Both parts share identical electrical specifications, package footprint (14-TSSOP), and operating parameters. No circuit modifications are required for pin-compatible substitution.

Q: What is the primary reason for substituting the TLV2464IPWRG4?

A: The TLV2464IPWRG4 is classified as an obsolete product. Substitution ensures access to active, readily available components that maintain identical or compatible electrical and mechanical specifications, supporting ongoing production and supply chain reliability.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All recommended substitute parts use the 14-TSSOP package with identical pin configuration and footprint dimensions (0.173" width, 4.40mm width). Direct PCB-level substitution is supported without layout modifications.

Q: What is the difference between the TLV2464IPWR and TLV2464IPWRG4?

A: The electrical and functional specifications are identical. The primary difference is product status: TLV2464IPWRG4 is obsolete, while TLV2464IPWR is active. The packaging designation suffix differs, but both parts are surface-mount 14-TSSOP devices with identical performance characteristics.

Q: Which substitute part offers the lowest power consumption?

A: The MCP6484-E/ST and MCP6484T-E/ST offer the lowest supply current at 240 µA per four channels, compared to the original specification of 550 µA. This represents a 56% reduction in power consumption. Trade-offs include lower output current per channel (12 mA versus 80 mA) and reduced gain bandwidth product (4 MHz versus 6.4 MHz).

Q: Which substitute part offers the highest slew rate and bandwidth?

A: The AD8604ARUZ-REEL and MCP6494-E/ST both provide slew rates of 6 V/µs, compared to the original 1.6 V/µs. Gain bandwidth products are 8.4 MHz (AD8604ARUZ-REEL) and 7.5 MHz (MCP6494-E/ST), compared to the original 6.4 MHz. These parts are suitable for higher-frequency signal processing applications.

Q: Does the LMV824DTBR2G support the full industrial temperature range?

A: The LMV824DTBR2G operates across -40°C to 85°C, which is narrower than the original specification of -40°C to 125°C. This part is suitable for applications not requiring the extended upper temperature limit of 125°C. All other electrical and mechanical parameters are compatible.

Q: What is the significance of the packaging designation (CT, TR, Tube)?

A: Packaging designations indicate the form in which parts are supplied: Cut Tape (CT) and Digi-Reel® for automated assembly, Tape & Reel (TR) for high-volume production, and Tube for manual handling or lower-volume applications. All three packaging formats contain electrically identical parts; selection depends on manufacturing process requirements and volume.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All recommended substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing protocols and environmental regulations.

Q: Can the MAX4094AUD+ or MAX4094AUD+T be used in high-frequency applications?

A: The MAX4094 series features a slew rate of 0.2 V/µs and gain bandwidth product of 500 kHz, significantly lower than the original specification (1.6 V/µs and 6.4 MHz). These parts are optimized for precision, low-noise applications rather than high-frequency signal processing. Use is limited to applications with bandwidth requirements below 500 kHz.

Q: What is the input bias current difference between the TLV2464IPWRG4 and AD8604ARUZ-REEL?

A: The TLV2464IPWRG4 specifies 1.3 nA input bias current, while the AD8604ARUZ-REEL specifies 0.2 pA (0.0002 nA). The AD8604ARUZ-REEL provides approximately 6,500 times lower input bias current due to its CMOS architecture, making it suitable for high-impedance input applications where input bias current is a critical design parameter.
