CLC5956IMTD Equivalent & Substitute Parts

Part Overview

The CLC5956IMTD is a 12-bit pipelined analog-to-digital converter manufactured by Texas Instruments, designed for single-channel differential input applications with a 65 MHz sampling rate. This component operates on dual 5V supply rails and is housed in a 48-TFSOP surface mount package.

The CLC5956IMTD has reached obsolete product status. Identifying functionally equivalent alternatives is necessary to support ongoing system maintenance, design updates, and procurement continuity for applications currently utilizing this device.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLC5956IMTD is determined by the following critical parameters:

• 12-bit resolution requirement
• 65 MHz sampling rate capability
• Single differential input channel
• Parallel data interface output
• Pipelined architecture
• 5V analog and digital supply operation
• 48-TFSOP package compatibility
• Surface mount configuration

The LTC1741CFW from Analog Devices Inc. satisfies all these core electrical and mechanical requirements, making it a direct functional equivalent for the obsolete CLC5956IMTD.

Parameter Comparison

Engineering Selection Recommendations

The LTC1741CFW is the direct equivalent for CLC5956IMTD replacement. Both devices share identical electrical specifications for resolution, sampling rate, input configuration, and supply voltage requirements. Both are packaged in the same 48-TFSOP form factor with identical pinout compatibility.

The LTC1741CFW offers the advantage of active product status with current manufacturing support and 2400 units available in inventory. The device is ROHS3 compliant, meeting modern regulatory requirements. The LTC1741CFW supports both external and internal reference configurations, providing additional design flexibility compared to the internal-only reference of the CLC5956IMTD.

Operating temperature range differs between the two devices. The CLC5956IMTD operates from -40°C to 85°C, while the LTC1741CFW operates from 0°C to 70°C. Applications requiring extended low-temperature operation below 0°C must account for this specification difference.

Frequently Asked Questions (FAQ)

Q: Can the LTC1741CFW directly replace the CLC5956IMTD in existing designs?

A: Yes. Both devices share identical pin configurations, package type (48-TFSOP), and core electrical specifications including 12-bit resolution, 65 MHz sampling rate, differential input, and 5V supply operation. No PCB layout modifications are required.

Q: What is the primary difference between these two devices?

A: The LTC1741CFW supports both external and internal reference configurations, while the CLC5956IMTD supports internal reference only. The LTC1741CFW also has a narrower operating temperature range (0°C to 70°C versus -40°C to 85°C).

Q: Are there any compliance considerations when switching from CLC5956IMTD to LTC1741CFW?

A: The LTC1741CFW is ROHS3 compliant, whereas the CLC5956IMTD is non-compliant. This makes the LTC1741CFW suitable for applications subject to RoHS regulations. Both devices are REACH unaffected and carry the same ECCN and HTSUS classifications.

Q: Does the LTC1741CFW require different circuit design considerations?

A: No design changes are required for basic operation. The additional external reference capability of the LTC1741CFW is optional and does not affect designs using internal reference configuration.

Q: What is the availability status of these parts?

A: The CLC5956IMTD is obsolete with 653 units in stock. The LTC1741CFW is an active product with 2400 units available, providing superior long-term supply assurance.
