TLC352CP Equivalent & Substitute Parts

Part Overview

The TLC352CP is a dual differential comparator IC manufactured by Texas Instruments, housed in an 8-pin DIP package for through-hole mounting. This LinCMOS™ series component operates across a wide supply voltage range of 1.4V to 16V (single supply) or ±0.7V to ±8V (dual supply), making it suitable for precision analog signal comparison applications in industrial and consumer electronics.

The TLC352CP is currently in Last Time Buy status, indicating that Texas Instruments has discontinued active production. This necessitates identification of equivalent substitute parts to ensure design continuity and long-term component availability for new production runs and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC352CP is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Dual differential comparator topology (2 elements)
• CMOS/MOS output stage with open-drain and TTL compatibility
• Supply voltage range: 1.4V ~ 16V (single) or ±0.7V ~ ±8V (dual)
• Input offset voltage maximum: 5mV @ 5V
• Input bias current maximum: 5pA @ 5V
• Output current capability: 20mA typical
• Quiescent current maximum: 400µA
• Operating temperature range: 0°C ~ 70°C

Mechanical Compatibility Criteria:

• Package type and pin configuration
• Mounting technology (through-hole vs. surface mount)
• Physical dimensions and lead spacing

The TLC352CDR is the direct manufacturer-recommended substitute, sharing identical electrical specifications while differing only in packaging format (8-SOIC surface mount versus 8-DIP through hole) and product status (Active versus Last Time Buy).

Parameter Comparison

Engineering Selection Recommendations

The TLC352CDR is the manufacturer-recommended substitute for the TLC352CP. Both components are manufactured by Texas Instruments and share identical electrical specifications, ensuring functional equivalence in circuit applications.

Selection Basis:

The TLC352CDR maintains full electrical compatibility with the TLC352CP across all specified parameters: dual differential comparator topology, identical supply voltage ranges, input offset voltage, input bias current, output current capability, and quiescent current specifications. Both components operate across the same temperature range and carry equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected).

The primary distinction is packaging format: the TLC352CP uses through-hole 8-DIP mounting, while the TLC352CDR uses surface-mount 8-SOIC technology. This difference requires PCB layout modification but does not affect electrical performance or functional compatibility.

The TLC352CDR holds Active product status, ensuring continued availability and manufacturing support from Texas Instruments, whereas the TLC352CP is in Last Time Buy status. The TLC352CDR also maintains higher inventory levels (2700 Pcs versus 1890 Pcs), supporting supply chain continuity for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the TLC352CDR directly replace the TLC352CP in existing designs?

A: Electrical substitution is complete. The TLC352CDR provides identical performance across all specified electrical parameters. However, physical substitution requires PCB redesign due to different package formats: the TLC352CP uses through-hole 8-DIP mounting while the TLC352CDR uses surface-mount 8-SOIC technology. Pin-to-pin electrical functionality remains unchanged.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by: dual differential comparator configuration, CMOS/MOS output stage with open-drain and TTL compatibility, supply voltage range (1.4V ~ 16V single or ±0.7V ~ ±8V dual), input offset voltage (5mV @ 5V maximum), input bias current (5pA @ 5V maximum), output current (20mA typical), quiescent current (400µA maximum), and operating temperature range (0°C ~ 70°C).

Q: Why is the TLC352CP in Last Time Buy status?

A: Last Time Buy status indicates that Texas Instruments has discontinued active production of this component. The TLC352CDR, sharing identical electrical specifications, represents the active alternative for new designs and ongoing production requirements.

Q: Are there compliance or certification differences between the TLC352CP and TLC352CDR?

A: Both components carry identical compliance certifications: ROHS3 Compliant and REACH Unaffected. No compliance or regulatory differences exist between the two parts.

Q: What packaging considerations apply when substituting the TLC352CDR for the TLC352CP?

A: The TLC352CP is packaged in 8-DIP through-hole format (0.300" spacing, 7.62mm), suitable for breadboard and through-hole PCB assembly. The TLC352CDR is packaged in 8-SOIC surface-mount format (0.154" width, 3.90mm), requiring surface-mount PCB assembly equipment and layout. Pin configuration and electrical function remain identical; only mounting technology and physical dimensions differ.
