TLV7022DDFR Equivalent & Substitute Parts

Part Overview

The TLV7022DDFR is a dual-channel general-purpose comparator manufactured by Texas Instruments, housed in a TSOT-23-8 surface-mount package. This device features open-drain, rail-to-rail output architecture and operates across a supply voltage range of 1.6V to 5.5V. The TLV7022DDFR is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when original inventory is unavailable, when alternative package configurations are required for specific PCB layouts, or when design flexibility across manufacturing sources is necessary.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV7022DDFR is determined by the following criteria:

Functional Compatibility Requirements:

• Dual-channel (2 elements) general-purpose comparator architecture
• Open-drain output configuration
• Supply voltage range overlap: minimum 1.6V to 5.5V operation
• Operating temperature range: -40°C to 125°C
• Surface-mount technology

Compliance & Regulatory Requirements:

• Active product status
• RoHS3 compliance
• REACH unaffected classification
• EAR99 export control classification

Package Considerations: Substitute parts may employ different surface-mount package geometries (SOT-23-8, 8-DFN) provided the pin count, electrical functionality, and mounting technology remain compatible with the application circuit design.

The TS332IQ2T from STMicroelectronics meets all functional and compliance criteria for substitution, with the primary distinction being package form factor (8-DFN versus TSOT-23-8).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The TLV7022DDFR remains the preferred component when TSOT-23-8 package geometry is specified in the PCB design and Texas Instruments sourcing is established. This device is actively manufactured and maintains full regulatory compliance across all applicable standards.

Substitution Conditions:

The TS332IQ2T from STMicroelectronics is a valid substitute when:

• PCB layout accommodates the 8-DFN (2x2) package footprint
• The upper supply voltage limit of 5V (versus 5.5V for TLV7022DDFR) is acceptable for the application
• Propagation delay of 720ns (versus 310ns for TLV7022DDFR) meets timing requirements
• Higher quiescent current (30µA versus 9µA) is acceptable for power budget
• Higher output current capability (93mA versus 33mA) is beneficial or neutral

Both devices maintain identical operating temperature ranges (-40°C to 125°C), dual-channel architecture, open-drain output configuration, and full RoHS3 compliance. Both are classified as active products with unlimited moisture sensitivity ratings.

Compliance Verification:

Both the TLV7022DDFR and TS332IQ2T carry EAR99 export classification and REACH unaffected status, permitting unrestricted use in equivalent applications without additional regulatory documentation.

Frequently Asked Questions (FAQ)

Q: Can the TS332IQ2T directly replace the TLV7022DDFR on an existing PCB?

A: Direct PCB replacement is not possible due to package differences. The TLV7022DDFR uses TSOT-23-8 (8-pin SOT-23), while the TS332IQ2T uses 8-DFN (2x2) with exposed pad. PCB layout and footprint redesign is required. Pin-to-pin functional compatibility exists for the dual-comparator architecture.

Q: What is the maximum supply voltage difference between these parts?

A: The TLV7022DDFR operates to 5.5V, while the TS332IQ2T operates to 5V maximum. Applications requiring supply voltages between 5V and 5.5V must use the TLV7022DDFR.

Q: How do propagation delays compare between these devices?

A: The TLV7022DDFR specifies 310ns maximum propagation delay, while the TS332IQ2T specifies 720ns maximum. Applications with timing-critical comparator switching requirements may require the TLV7022DDFR.

Q: Are there differences in quiescent current consumption?

A: Yes. The TLV7022DDFR draws 9µA maximum quiescent current, while the TS332IQ2T draws 30µA maximum. Battery-powered or ultra-low-power applications should prioritize the TLV7022DDFR.

Q: Do both parts support rail-to-rail output?

A: The TLV7022DDFR explicitly specifies rail-to-rail output. The TS332IQ2T specifies open-drain output without explicit rail-to-rail designation. Verify output voltage swing requirements for your application.

Q: Are both devices RoHS3 compliant?

A: Yes. Both the TLV7022DDFR and TS332IQ2T are RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity ratings, permitting use in equivalent applications without additional environmental restrictions.

Q: What is the input offset voltage difference?

A: The TLV7022DDFR specifies 8mV maximum input offset at 5V, while the TS332IQ2T specifies 5mV maximum. The TS332IQ2T exhibits superior input offset performance.

Q: Can these parts be used interchangeably in new designs?

A: Functional interchangeability exists only when package form factor is not constrained. New designs should specify one device based on package availability, supply voltage requirements, propagation delay specifications, and power consumption targets rather than treating them as interchangeable.
