TLV3704IDRG4 Equivalent & Substitute Parts

Part Overview

The TLV3704IDRG4 is a general-purpose CMOS comparator featuring four independent comparator elements with push-pull, rail-to-rail output configuration. This device operates across a wide supply voltage range of 2.7V to 16V (single supply) or ±1.35V to ±8V (dual supply), making it suitable for diverse analog signal conditioning applications.

The TLV3704IDRG4 is currently discontinued at DiGi Electronics, necessitating identification of equivalent alternatives that maintain functional and electrical compatibility. Substitute parts must preserve the core electrical characteristics, package form factor, and operational parameters to ensure seamless integration into existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Package form factor: 14-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Number of comparator elements: 4
• Output configuration: CMOS, Push-Pull, Rail-to-Rail
• Supply voltage range compatibility
• Input offset voltage specification
• Input bias current specification
• Quiescent current specification
• Operating temperature range
• RoHS3 compliance

Parametric Equivalent Category: Parts that maintain identical electrical specifications and package configuration as the main part.

Manufacturer Recommended Category: Parts that provide functional equivalence with allowable variations in specific parameters (supply voltage range, quiescent current, propagation delay, hysteresis) while maintaining the same package, output type, and core operational characteristics.

Parameter Comparison

Engineering Selection Recommendations

TLV3704IDR (Parametric Equivalent): This part maintains complete electrical and mechanical equivalence to the TLV3704IDRG4, differing only in packaging format (Cut Tape versus DiGi Electronics's original specification). The TLV3704IDR is designated as Last Time Buy, indicating limited future availability. This part is suitable for direct substitution where supply voltage extends beyond 5.5V or where the extended operating temperature range to 125°C is required.

MAX993ESD+ and MAX993ESD+T (Manufacturer Recommended): These Analog Devices/Maxim Integrated parts provide functional equivalence with restricted supply voltage range (2.5V ~ 5.5V). Both parts are in Active product status with established supply chains. The MAX993ESD+T variant is supplied in Tape & Reel packaging, while MAX993ESD+ is supplied in Tube packaging. These parts are suitable for applications operating within the 2.5V to 5.5V supply range. The reduced CMRR/PSRR specifications (80dB versus 88dB/105dB) and increased quiescent current (24µA versus 1µA) must be evaluated against application requirements.

MAX995ESD+ (Manufacturer Recommended): This part offers the fastest propagation delay (210ns) among the substitute options and is in Active product status. The supply voltage range is restricted to 2.5V ~ 5.5V. Quiescent current is elevated to 96µA, which may impact battery-powered applications. This part is suitable for applications requiring faster response time within the restricted supply voltage range.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical 14-SOIC package configuration, ensuring mechanical and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX993ESD+ or MAX995ESD+ be used in applications requiring supply voltages above 5.5V?

A: No. The MAX993ESD+ and MAX995ESD+ are specified for supply voltages of 2.5V ~ 5.5V only. Applications requiring operation at 16V or higher must use TLV3704IDR, which maintains the extended supply voltage range of 2.7V ~ 16V.

Q: What is the difference between MAX993ESD+ and MAX993ESD+T?

A: Both parts are electrically identical. The difference is packaging format: MAX993ESD+ is supplied in Tube packaging, while MAX993ESD+T is supplied in Tape & Reel (TR) packaging. Selection depends on assembly process requirements and volume considerations.

Q: Is TLV3704IDR a direct replacement for TLV3704IDRG4?

A: TLV3704IDR is a parametric equivalent with identical electrical specifications and operating characteristics. The primary difference is packaging format (Cut Tape versus the original specification). Both parts are suitable for direct substitution in existing designs. However, TLV3704IDR is designated Last Time Buy, indicating limited future availability.

Q: How do the quiescent current specifications of substitute parts affect circuit design?

A: The TLV3704IDRG4 and TLV3704IDR specify maximum quiescent current of 1µA. The MAX993ESD+ and MAX993ESD+T specify 24µA, while MAX995ESD+ specifies 96µA. In battery-powered or low-power applications, this difference becomes significant. Applications with strict power consumption budgets should retain TLV3704IDR if available.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts—TLV3704IDR, MAX993ESD+, MAX993ESD+T, and MAX995ESD+—are ROHS3 compliant with MSL Level 1 rating, meeting environmental and regulatory requirements equivalent to the original TLV3704IDRG4.

Q: What is the impact of reduced CMRR/PSRR in MAX99x series parts?

A: The MAX99x series parts specify 80dB CMRR and 80dB PSRR compared to 88dB CMRR and 105dB PSRR for the TLV3704 series. This represents reduced common-mode and power-supply rejection performance. Applications with high noise immunity requirements or sensitive analog signal conditioning may require evaluation of this specification change.

Q: Can MAX995ESD+ be used as a direct replacement for MAX993ESD+?

A: MAX995ESD+ offers faster propagation delay (210ns versus 450ns) and lower hysteresis (±2.5mV versus ±3mV), but operates at higher quiescent current (96µA versus 24µA). Substitution is application-dependent and requires evaluation of speed and power consumption trade-offs.
