TLC352CPWR Equivalent & Substitute Parts

Part Overview

The TLC352CPWR is a dual differential comparator IC manufactured by Texas Instruments in the LinCMOS™ series. This component features CMOS, MOS, open-drain, and TTL output configurations housed in an 8-TSSOP surface mount package. The TLC352CPWR is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. Active alternatives with compatible electrical and mechanical specifications are available to maintain system functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC352CPWR are selected based on strict electrical and mechanical compatibility criteria. The following parameters determine valid substitution:

Critical Matching Parameters:

• Package type: 8-TSSOP surface mount configuration
• Number of comparator elements: 2 differential comparators
• Output type compatibility: CMOS and open-drain outputs
• Supply voltage range: Must encompass or match the original 1.4V ~ 16V single supply range
• Input offset voltage: Maximum 5mV specification
• Current output capability: Minimum 20mA typical
• RoHS3 compliance and MSL Level 1 rating

Identified Substitute Parts:

1. TLC352IPWR (Texas Instruments) – Manufacturer recommended substitute with identical electrical specifications and active product status
2. TS393IPT (STMicroelectronics) – Cross-manufacturer alternative with compatible output types and enhanced operating temperature range

Parameter Comparison

Engineering Selection Recommendations

TLC352IPWR (Primary Substitute): The TLC352IPWR is the manufacturer-recommended substitute for the obsolete TLC352CPWR. Both parts share identical electrical specifications, including supply voltage range, input offset voltage, output current, and quiescent current characteristics. The TLC352IPWR maintains active product status with ROHS3 compliance and MSL Level 1 rating. The primary difference is packaging format (Tape & Reel versus Cut Tape) and extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C). This substitute provides direct functional equivalence with no design modifications required.

TS393IPT (Secondary Substitute): The TS393IPT from STMicroelectronics is a cross-manufacturer alternative suitable for applications where the TLC352IPWR is unavailable. This part maintains the 8-TSSOP package and dual comparator configuration with CMOS and open-drain outputs. Key differences include a higher minimum supply voltage (2.7V single supply versus 1.4V), lower input bias current (1pA versus 5pA), and significantly lower quiescent current (25µA versus 400µA). The TS393IPT supports an extended operating temperature range (-40°C ~ 125°C) and is classified as a general-purpose comparator rather than differential type. Selection of this substitute requires verification that the minimum 2.7V supply voltage is compatible with the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the TLC352IPWR be used as a direct replacement for the TLC352CPWR? A: Yes. The TLC352IPWR is the manufacturer-recommended substitute with identical electrical specifications and package configuration. No circuit modifications are required for substitution.

Q: What is the primary difference between TLC352CPWR and TLC352IPWR? A: The TLC352CPWR is obsolete with a 0°C ~ 70°C operating temperature range, while the TLC352IPWR is active with an extended -40°C ~ 85°C range. Packaging format differs (Cut Tape versus Tape & Reel), but electrical performance is identical.

Q: Is the TS393IPT compatible with designs using the TLC352CPWR? A: The TS393IPT is mechanically and functionally compatible in the 8-TSSOP package with dual comparators and open-drain outputs. However, the minimum supply voltage is 2.7V (versus 1.4V for TLC352CPWR). Applications operating below 2.7V single supply require circuit redesign or alternative parts.

Q: What are the key electrical differences between TLC352IPWR and TS393IPT? A: The TS393IPT has lower input bias current (1pA versus 5pA), significantly lower quiescent current (25µA versus 400µA), and a higher minimum supply voltage (2.7V versus 1.4V). The TS393IPT also supports a wider operating temperature range (-40°C ~ 125°C).

Q: Are all substitute parts RoHS3 compliant? A: Yes. Both TLC352IPWR and TS393IPT are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original TLC352CPWR specifications.

Q: Which substitute should be selected for new designs? A: The TLC352IPWR is recommended for new designs as the manufacturer-recommended active substitute with identical electrical specifications to the obsolete TLC352CPWR. The TS393IPT is suitable when TLC352IPWR availability is limited and circuit supply voltage requirements are compatible with the 2.7V minimum specification.
