LMC6464BIN CMOS Amplifier Equivalent & Substitute Parts

Part Overview

The LMC6464BIN is a CMOS amplifier integrated circuit manufactured by Texas Instruments, containing four independent operational amplifier circuits in a 14-pin DIP package. This device is classified as Obsolete, indicating it has reached end-of-life status and is no longer in active production. The LMC6464BIN features rail-to-rail output capability, making it suitable for low-voltage analog signal processing applications requiring minimal power consumption.

Due to its obsolete status, locating equivalent or substitute parts is necessary for ongoing design support, maintenance, and new production requirements. Substitute parts must maintain electrical compatibility across critical parameters including supply voltage range, amplifier type, circuit count, and output characteristics.

Engineering Selection Recommendations

LMC6464BIN/NOPB is the direct equivalent substitute for the LMC6464BIN. Both parts are manufactured by Texas Instruments and share identical electrical specifications and mechanical packaging. The primary distinction is product status and regulatory compliance:

The LMC6464BIN/NOPB carries a "Last Time Buy" status, indicating limited availability but continued support from the manufacturer. This part achieves ROHS3 compliance, whereas the original LMC6464BIN is RoHS non-compliant. The "/NOPB" suffix indicates lead-free plating, which aligns with modern environmental and regulatory standards.

For applications requiring new component procurement or long-term design support, the LMC6464BIN/NOPB is the appropriate selection. Both parts maintain identical electrical performance across all critical parameters, ensuring seamless functional substitution in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can LMC6464BIN/NOPB be used as a direct replacement for LMC6464BIN?

A: Yes. The LMC6464BIN/NOPB is electrically and mechanically identical to the LMC6464BIN. All electrical parameters, including slew rate, gain bandwidth product, supply current, and output current, are equivalent. Both use the same 14-DIP package with 0.300" (7.62mm) pin spacing, enabling direct PCB compatibility.

Q: What is the significance of the "/NOPB" suffix?

A: The "/NOPB" designation indicates lead-free plating on the component leads. This reflects compliance with RoHS3 standards and modern environmental regulations. The electrical and functional performance of the device remains unchanged.

Q: Why is the LMC6464BIN classified as Obsolete?

A: The LMC6464BIN has reached end-of-life status and is no longer manufactured by Texas Instruments. The LMC6464BIN/NOPB represents the current equivalent offering with updated compliance certifications.

Q: Are there any differences in thermal performance between these parts?

A: No. Both parts operate across the identical temperature range of -40°C to 85°C (TJ) and maintain the same supply current specifications of 90 µA across four channels.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The LMC6464BIN and LMC6464BIN/NOPB are pin-compatible and functionally equivalent. No circuit modifications are required for substitution.

Q: What is the package compatibility consideration?

A: Both parts use a 14-pin DIP package with 0.300" (7.62mm) pitch. This standard through-hole package is compatible with conventional PCB layouts and does not require design changes for substitution.
