TLC339IPW Equivalent & Substitute Parts

Part Overview

The TLC339IPW is a general-purpose CMOS comparator with open-drain output configuration, manufactured by Texas Instruments in a 14-TSSOP surface-mount package. This device operates across a wide supply voltage range of 3V to 16V and features four independent comparator elements per IC. The TLC339IPW is currently in Last Time Buy status, making identification of equivalent and substitute parts essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC339IPW is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of comparator elements: 4
• Output type: CMOS, Open-Drain configuration
• Supply voltage range: 3V ~ 16V
• Package compatibility: 14-pin surface-mount
• Input offset voltage: ≤ 5mV
• Quiescent current: ≤ 125µA

Substitute Categories:

Category 1 - Direct Packaging Equivalent: TLC339IPWR differs from the main part only in packaging format (Tape & Reel vs. Tube). All electrical specifications, pin configuration, and functional characteristics remain identical. This substitute maintains the same 14-TSSOP package footprint and is suitable for direct replacement in production environments.

Category 2 - Functional Equivalent with Package Variation: CMP401GSZ (Analog Devices Inc.) provides four comparator elements with CMOS and TTL output options. However, this device uses a 16-SOIC package instead of 14-TSSOP, requiring PCB layout modification. The supply voltage specification (±5V) is more restrictive than the TLC339IPW's 3V ~ 16V range. Propagation delay is significantly faster (30ns vs. 4.5µs), and quiescent current is lower (6mA/1mA vs. 125µA).

Category 3 - Functional Equivalent with Operational Differences: TS374CDT (STMicroelectronics) is a differential comparator with four elements in a 14-SOIC package. This device supports dual supply operation (±1.5V ~ 8V) and single supply (3V ~ 16V), matching the TLC339IPW's voltage range. However, the operating temperature range is limited to 0°C ~ 70°C, and the package is 14-SOIC rather than 14-TSSOP, requiring PCB footprint changes.

Parameter Comparison

Engineering Selection Recommendations

TLC339IPWR (Texas Instruments): This is the primary recommended substitute for the TLC339IPW. Both devices are manufactured by Texas Instruments and share identical electrical specifications, pin configuration, and functional performance. The only difference is packaging format: TLC339IPWR is supplied in Tape & Reel format suitable for automated assembly, while TLC339IPW is supplied in Tube format. TLC339IPWR maintains Active product status, ensuring long-term availability and supply chain continuity. This substitute requires no design changes and is suitable for direct replacement in all applications.

CMP401GSZ (Analog Devices Inc.): This substitute is suitable only for applications where the 16-SOIC package footprint can be accommodated through PCB redesign. The CMP401GSZ offers superior propagation delay performance (30ns vs. 4.5µs) and lower quiescent current, making it advantageous for high-speed or power-sensitive applications. However, the restricted supply voltage specification (±5V) limits its use to designs operating within this range. The extended operating temperature range (-40°C ~ 125°C) provides additional thermal margin compared to the TLC339IPW. This substitute is suitable only when PCB layout modification is feasible and supply voltage requirements align.

TS374CDT (STMicroelectronics): This substitute is suitable for applications requiring differential comparator functionality with flexible supply voltage options. The TS374CDT supports both single-supply (3V ~ 16V) and dual-supply (±1.5V ~ 8V) operation, matching the TLC339IPW's voltage range. However, the operating temperature range is restricted to 0°C ~ 70°C, making this substitute unsuitable for applications requiring extended temperature operation. The 14-SOIC package requires PCB footprint modification. This substitute is suitable only when operating temperature requirements do not exceed 70°C and PCB layout changes are acceptable.

Frequently Asked Questions (FAQ)

Q: Can TLC339IPWR be used as a direct replacement for TLC339IPW without any design changes?

A: Yes. TLC339IPWR is electrically and functionally identical to TLC339IPW. Both devices share the same 14-TSSOP package footprint, pin configuration, and electrical specifications. The only difference is the packaging format (Tape & Reel vs. Tube), which does not affect circuit performance or PCB assembly compatibility.

Q: What are the key differences between TLC339IPW and CMP401GSZ?

A: The primary differences are package type (14-TSSOP vs. 16-SOIC), supply voltage specification (3V ~ 16V vs. ±5V), and propagation delay (4.5µs vs. 30ns). CMP401GSZ offers faster response time and lower quiescent current but requires PCB layout modification and operates only within ±5V supply range. Use CMP401GSZ only when high-speed performance is required and supply voltage is restricted to ±5V.

Q: Is TS374CDT compatible with the TLC339IPW in terms of package footprint?

A: No. TS374CDT uses a 14-SOIC package, while TLC339IPW uses a 14-TSSOP package. Although both are 14-pin surface-mount packages, the pin spacing and footprint dimensions differ, requiring PCB redesign for substitution.

Q: What is the operating temperature limitation of TS374CDT compared to TLC339IPW?

A: TLC339IPW operates from -40°C to 85°C, while TS374CDT operates from 0°C to 70°C. TS374CDT is unsuitable for applications requiring operation below 0°C or above 70°C.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TLC339IPWR, CMP401GSZ, and TS374CDT are all ROHS3 compliant, matching the compliance status of the main part TLC339IPW.

Q: Which substitute part offers the best performance for low-power applications?

A: CMP401GSZ offers the lowest quiescent current specification (6mA/1mA) compared to TLC339IPW (125µA) and TS374CDT (250µA). However, CMP401GSZ is suitable only for applications operating within ±5V supply range and requiring 16-SOIC package compatibility.
