MAX970EEE-T Equivalent & Substitute Parts

Part Overview

The MAX970EEE-T is a general-purpose comparator IC featuring four independent comparators with open-drain, rail-to-rail output configuration in a 16-QSOP surface-mount package. This device operates across a wide supply voltage range of 1.6V to 5.5V, making it suitable for low-power and mixed-signal applications requiring precision voltage comparison.

The MAX970EEE-T is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for existing applications and new designs requiring comparable performance characteristics.

Electrical Equivalence Criteria:

• Number of comparator elements: 4
• Output configuration: Open-Drain, Rail-to-Rail
• Supply voltage range: 1.6V ~ 5.5V (minimum requirement)
• Input offset voltage: 10mV @ 5.5V (maximum)
• Input bias current: 0.05µA @ 5.5V (maximum)
• Quiescent current: 18µA (maximum)
• CMRR / PSRR performance: 56.48dB CMRR, 80dB PSRR (minimum)
• Propagation delay: 20µs (maximum)
• Hysteresis: ±1mV
• Operating temperature range: -40°C ~ 85°C

Mechanical Equivalence Criteria:

• Package type: 16-SSOP (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Pin configuration and footprint compatibility

The MAX970EEE+T meets all electrical and mechanical equivalence requirements and serves as a direct substitute for the obsolete MAX970EEE-T variant.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can MAX970EEE+T be used as a direct replacement for MAX970EEE-T?

A: Yes. The MAX970EEE+T is electrically and mechanically equivalent to the MAX970EEE-T. All electrical parameters, pin configuration, and package dimensions are identical. The primary differences are product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. Tube).

Q: What is the difference between the packaging formats?

A: The MAX970EEE-T is supplied in tube packaging, while the MAX970EEE+T is supplied in Tape & Reel (TR) format. Both formats contain the same component with identical specifications. Tape & Reel packaging is standard for active products and is optimized for automated pick-and-place assembly equipment.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical electrical specifications including supply voltage range (1.6V ~ 5.5V), input offset voltage (10mV @ 5.5V), quiescent current (18µA), propagation delay (20µs), and all other performance parameters.

Q: Why is the MAX970EEE-T marked as obsolete?

A: The MAX970EEE-T is classified as obsolete due to its RoHS non-compliant status. The MAX970EEE+T represents the current active equivalent with ROHS3 compliance, ensuring alignment with modern environmental regulations and manufacturing standards.

Q: Is the 16-SSOP package footprint identical between both parts?

A: Yes. Both parts use the 16-SSOP package with 0.154" width (3.90mm). The physical dimensions, pin spacing, and PCB footprint are identical, enabling direct board-level substitution without layout modifications.

Q: What is the moisture sensitivity level for these comparators?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage or handling.
