TLC372CPSG4 Equivalent & Substitute Parts

Part Overview

The TLC372CPSG4 is a dual differential comparator IC manufactured by Texas Instruments, part of the LinCMOS™ series. This surface-mount component operates across a wide supply voltage range (3V to 16V single supply, ±1.5V to ±8V dual supply) and features CMOS/MOS open-drain TTL output architecture. The device is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC372CPSG4 is determined by strict equivalence across the following critical parameters:

• Dual differential comparator architecture (2 elements)
• CMOS/MOS open-drain TTL output configuration
• Supply voltage compatibility: 3V to 16V (single) and ±1.5V to ±8V (dual)
• Input offset voltage specification: 5mV maximum at 5V
• Input bias current specification: 5pA maximum at 5V
• Output current capability: 20mA typical
• 8-SOIC surface-mount package with 5.30mm width
• Operating temperature range: 0°C to 70°C
• RoHS3 compliance and MSL Level 1 rating

The TLC372CPS qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format (tube vs. standard) and product status (Last Time Buy vs. Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The TLC372CPS is a direct functional equivalent to the TLC372CPSG4. Both devices share identical electrical specifications, package geometry, and compliance certifications (ROHS3, MSL Level 1). Selection between these parts should be based on:

• Product availability and lead time requirements
• Packaging format compatibility with assembly processes (tube packaging for TLC372CPS)
• Supply chain status (TLC372CPS is Last Time Buy; TLC372CPSG4 is Discontinued)
• Inventory requirements and procurement timelines

No electrical or mechanical redesign is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can TLC372CPS replace TLC372CPSG4 in existing designs? A: Yes. Both parts are electrically and mechanically identical. The TLC372CPS operates across the same supply voltage ranges, maintains identical input/output specifications, and uses the same 8-SOIC package footprint.

Q: What is the difference between TLC372CPSG4 and TLC372CPS? A: The primary differences are packaging format (standard vs. tube) and product lifecycle status. TLC372CPSG4 is discontinued; TLC372CPS is Last Time Buy. Electrical performance and package dimensions are identical.

Q: Are there any compliance or certification differences? A: No. Both parts carry ROHS3 compliance and MSL Level 1 rating. No additional qualification is required for substitution.

Q: Can these parts be used interchangeably on the same PCB assembly? A: Yes. Both parts use the 8-SOIC surface-mount package with identical pin configuration and footprint dimensions (0.209" width, 5.30mm).

Q: What supply voltages are supported? A: Both parts support single supply operation from 3V to 16V and dual supply operation from ±1.5V to ±8V.
