TLV7256IDDUR Equivalent & Substitute Parts

Part Overview

The TLV7256IDDUR is a general-purpose CMOS comparator manufactured by Texas Instruments, featuring dual elements in an 8-VSSOP surface mount package. This device operates across a 1.8V to 5V supply range and delivers push-pull TTL-compatible outputs suitable for signal comparison applications. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameters while maintaining compatibility with the application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV7256IDDUR is determined by the following critical parameters:

Functional Equivalence Criteria:

• Dual-element general-purpose comparator architecture
• CMOS and TTL-compatible output stages
• Supply voltage range compatibility (minimum 1.8V to 5V operation)
• Surface mount packaging with 8-pin configuration
• Operating temperature range of -40°C to 85°C
• Active product status with RoHS3 compliance

Identified Substitutes:

MAX962ESA+T and MAX962EUA+T (Analog Devices Inc./Maxim Integrated): Both variants meet functional requirements with extended supply voltage range (2.7V ~ 5.5V), superior input offset voltage (1.5mV @ 5V), and faster propagation delay (7ns). Output type includes CMOS and TTL compatibility. Packaging differs (8-SOIC and 8-uMAX/uSOP respectively) but maintains surface mount configuration. Both are active products with RoHS3 compliance.

TS3702CDT (STMicroelectronics): Meets functional requirements with extended supply voltage range (2.7V ~ 16V, ±1.35V ~ 8V), CMOS push-pull output, and lower input bias current (1pA @ 5V). Packaging is 8-SOIC surface mount. Active product status with RoHS3 compliance. Operating temperature range is 0°C ~ 70°C.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full RoHS3 compliance, meeting regulatory requirements equivalent to the TLV7256IDDUR.

MAX962ESA+T is suitable for applications requiring 8-SOIC packaging with extended supply voltage range and improved input offset voltage performance. This variant provides faster propagation delay characteristics.

MAX962EUA+T is suitable for applications where 8-uMAX/uSOP packaging is compatible with board layout constraints. This variant offers the same electrical performance as MAX962ESA+T with a narrower package width (3.00mm versus 3.90mm).

TS3702CDT is suitable for applications requiring extended supply voltage range up to 16V or dual supply operation (±1.35V ~ 8V), with superior input bias current performance (1pA @ 5V). The 8-SOIC package matches MAX962ESA+T dimensions. Operating temperature range is limited to 0°C ~ 70°C, which excludes applications requiring full -40°C ~ 85°C operation.

Package geometry differences require PCB layout verification. The TLV7256IDDUR uses 8-VFSOP (2.30mm width), while substitutes use either 8-SOIC (3.90mm width) or 8-uMAX/uSOP (3.00mm width). Pin pitch and footprint compatibility must be confirmed for each application.

Frequently Asked Questions (FAQ)

Q: Can MAX962ESA+T directly replace TLV7256IDDUR without PCB modification?

A: Electrical substitution is valid. However, package geometry differs (8-SOIC versus 8-VFSOP), requiring PCB footprint redesign. Pin configuration and pitch must be verified against application schematics.

Q: What is the primary advantage of MAX962EUA+T over MAX962ESA+T?

A: Both variants share identical electrical specifications. MAX962EUA+T uses 8-uMAX/uSOP packaging (3.00mm width) versus 8-SOIC (3.90mm width), providing a narrower footprint for space-constrained applications.

Q: Is TS3702CDT suitable for all TLV7256IDDUR applications?

A: TS3702CDT meets most electrical requirements with superior input bias current and extended supply voltage range. However, operating temperature range is limited to 0°C ~ 70°C. Applications requiring -40°C operation must use alternative substitutes or the original part.

Q: How do propagation delay differences affect circuit performance?

A: TLV7256IDDUR specifies 680ns maximum propagation delay. MAX962ESA+T and MAX962EUA+T specify 7ns, representing significantly faster response. TS3702CDT does not specify propagation delay. Faster devices may require circuit timing verification to prevent unintended behavior in delay-sensitive applications.

Q: Are all substitutes compatible with 1.8V supply operation?

A: No. MAX962ESA+T, MAX962EUA+T, and TS3702CDT all require minimum 2.7V supply voltage. Applications operating at 1.8V must use TLV7256IDDUR or identify alternative parts with lower supply voltage specifications.

Q: What packaging considerations apply when switching from TLV7256IDDUR?

A: All substitutes use standard 8-pin surface mount packages (SOIC or uMAX/uSOP) versus the original 8-VFSOP. Verify PCB footprint compatibility, solder reflow profile requirements, and board layout constraints before implementation.
