TLC352ID Equivalent & Substitute Parts

Part Overview

The TLC352ID is a dual differential comparator IC manufactured by Texas Instruments in the LinCMOS™ series, housed in an 8-SOIC surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The TLC352ID operates across a wide supply voltage range (1.4V ~ 16V single supply, ±0.7V ~ 8V dual supply) and features CMOS, MOS, open-drain, and TTL output configurations suitable for precision comparison applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC352ID is determined by the following critical parameters:

Primary Substitution Criteria:

• Package type: 8-SOIC surface mount form factor
• Number of elements: Dual comparator configuration
• Supply voltage compatibility: Overlap with 1.4V ~ 16V single supply range
• Output type: CMOS, MOS, or open-drain capability
• Input offset voltage: Maximum 5mV specification
• Input bias current: Maximum 5pA specification
• Output current: Minimum 20mA capability
• Quiescent current: Maximum 400µA specification
• Operating temperature: Minimum -40°C lower bound
• Compliance: ROHS3 compliant

Substitute Parts Identified:

Group 1 - Direct Functional Equivalents (Differential Type):

• TLC352IDR (Texas Instruments) - Active status, identical electrical specifications, cut tape packaging
• TS372CDT (STMicroelectronics) - Active status, differential type, tape & reel packaging
• TS372IDT (STMicroelectronics) - Active status, differential type, extended temperature range, cut tape packaging

Group 2 - General Purpose Alternatives (Open-Drain Output):

• NCS3402DR2G (onsemi) - Active status, general purpose type, open-drain output, tape & reel packaging
• TS393CDT (STMicroelectronics) - Active status, general purpose type, cut tape packaging
• TS393IDT (STMicroelectronics) - Active status, general purpose type, extended temperature range, cut tape packaging
• TS393IYDT (STMicroelectronics) - Active status, general purpose type, automotive grade AEC-Q100 qualified, extended temperature range, cut tape packaging

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation - TLC352IDR: The TLC352IDR from Texas Instruments is the direct functional equivalent to the obsolete TLC352ID. It maintains identical electrical specifications, the same differential comparator architecture, and equivalent supply voltage range. The part is in active production status with ROHS3 compliance. The only difference is packaging format (cut tape and Digi-Reel versus tube), which does not affect electrical performance. This is the preferred substitution path for direct replacement.

Secondary Recommendations - STMicroelectronics TS372 Series: The TS372CDT and TS372IDT maintain the differential comparator type and are functionally compatible. Both are active products with ROHS3 compliance. The TS372IDT offers extended operating temperature range (-40°C ~ 125°C) compared to the TS372CDT (0°C ~ 70°C). Supply voltage minimum is raised to 3V, which may require circuit evaluation in low-voltage applications. Input offset voltage is doubled to 10mV maximum.

Alternative Options - STMicroelectronics TS393 Series and onsemi NCS3402DR2G: The TS393CDT, TS393IDT, and TS393IYDT are general purpose comparators with open-drain output. These parts offer lower quiescent current (25µA versus 400µA) and are suitable for applications where power consumption is critical. The TS393IYDT includes automotive grade AEC-Q100 qualification for automotive applications. The NCS3402DR2G from onsemi provides the lowest quiescent current (640nA) and extended temperature range but features reduced output current (10mA versus 20mA).

All substitute parts are ROHS3 compliant and maintain the 8-SOIC surface mount package form factor.

Frequently Asked Questions (FAQ)

Q: Can TLC352IDR be used as a direct replacement for TLC352ID? A: Yes. The TLC352IDR is electrically identical to the TLC352ID with matching supply voltage range, input offset voltage, input bias current, output current, and quiescent current specifications. The only difference is packaging format (cut tape and Digi-Reel versus tube), which does not affect circuit performance.

Q: What is the key difference between differential and general purpose comparator types in this list? A: Differential comparators (TLC352ID, TLC352IDR, TS372CDT, TS372IDT) are optimized for comparing two input signals with high common-mode rejection. General purpose comparators (TS393 series, NCS3402DR2G) are designed for broader application flexibility. Both types are functionally compatible in most circuit topologies, but differential types provide superior performance in noise-sensitive environments.

Q: Are the TS372 parts suitable replacements if my circuit operates below 3V? A: No. The TS372 series has a minimum supply voltage of 3V, whereas the TLC352ID operates down to 1.4V. For applications requiring operation below 3V, use TLC352IDR, TS393 series, or NCS3402DR2G, which support lower supply voltages.

Q: What is the advantage of TS393IYDT over TS393IDT? A: The TS393IYDT is qualified to AEC-Q100 automotive standards and carries automotive grade designation. Both parts have identical electrical specifications and operating temperature range (-40°C ~ 125°C). Select TS393IYDT for automotive applications requiring AEC-Q100 qualification.

Q: Why does NCS3402DR2G have lower output current (10mA) compared to other options? A: The NCS3402DR2G is optimized for low quiescent current operation (640nA) at the trade-off of reduced output drive capability. This part is suitable for battery-powered or low-power applications where output current demand does not exceed 10mA.

Q: Are all substitute parts available in 8-SOIC package? A: Yes. All substitute parts listed are housed in 8-SOIC (0.154", 3.90mm width) surface mount packages, maintaining mechanical compatibility with the original TLC352ID footprint.

Q: Do all substitute parts meet ROHS3 compliance? A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the environmental compliance status of the original TLC352ID.
