MAX964ESE Equivalent & Substitute Parts

Part Overview

The MAX964ESE is a general-purpose CMOS/TTL comparator IC manufactured by Analog Devices Inc./Maxim Integrated, featuring four independent comparator elements in a 16-SOIC package. This device is classified as obsolete, making equivalent and substitute parts necessary for new designs and production continuity. The MAX964ESE operates across a 2.7V to 5.5V supply range with low input offset voltage (1.5mV @ 5V) and fast propagation delay (7ns), suitable for precision signal comparison applications.

Substitute Part Grouping Explanation

Substitution for the MAX964ESE is determined by the following critical parameters:

Primary Substitution Criteria:

Number of comparator elements (4 required)
Output type compatibility (CMOS/TTL)
Supply voltage range overlap (minimum 2.7V ~ 5.5V compatibility)
Package form factor (16-SOIC or functionally equivalent)
Input offset voltage and propagation delay performance
Operating temperature range coverage

Substitution Categories:

Direct Equivalent (Same Package, Same Manufacturer): MAX964ESE+ maintains identical electrical specifications and 16-SOIC packaging, differing only in product status (Active vs. Obsolete) and packaging format (Tube vs. standard).

Functional Alternatives (Different Manufacturer, Different Package): TLC3704 series devices from Texas Instruments provide four-element comparator functionality with CMOS/TTL output capability. These devices operate across a wider supply range (3V ~ 16V) and are available in multiple package options (14-SOIC, 14-TSSOP). Trade-offs include different propagation delay characteristics (4.5µs vs. 7ns) and package pin counts (14-pin vs. 16-pin).

Engineering Selection Recommendations

MAX964ESE+ (Direct Equivalent): This is the primary replacement for obsolete MAX964ESE stock. It maintains identical electrical performance, supply voltage range, and thermal operating limits. The only differences are active product status and packaging format (Tube). This option requires no circuit redesign and provides the shortest qualification timeline.

TLC3704CDR (14-SOIC Package): Suitable for applications where the wider supply voltage range (3V ~ 16V) and lower input bias current (5pA vs. 15µA) provide design advantages. The 14-SOIC package requires PCB layout modification due to reduced pin count (14 vs. 16). Operating temperature range is limited to 0°C ~ 70°C, restricting use in extended temperature applications. Propagation delay is significantly slower (4.5µs vs. 7ns), making this option unsuitable for high-speed comparison circuits.

TLC3704CPWR (14-TSSOP Package): Functionally equivalent to TLC3704CDR with identical electrical specifications. The 14-TSSOP package offers reduced board area compared to SOIC variants. This option is appropriate for space-constrained designs where the operating temperature range (0°C ~ 70°C) and propagation delay characteristics are acceptable.

TLC3704QDRG4Q1 (Automotive Grade, 14-SOIC Package): This variant extends the operating temperature range to -40°C ~ 125°C and includes AEC-Q100 automotive qualification. It is the only substitute option suitable for automotive and extended temperature applications. Higher quiescent current (175µA vs. 9mA in MAX964ESE) must be evaluated for power budget impact. Like other TLC3704 variants, it requires PCB layout modification and is unsuitable for high-speed applications due to propagation delay characteristics.

Frequently Asked Questions (FAQ)

Q: Can MAX964ESE+ be used as a direct replacement for MAX964ESE?

A: Yes. MAX964ESE+ is electrically and functionally identical to MAX964ESE. Both devices operate across 2.7V ~ 5.5V, feature four comparator elements with CMOS/TTL output, and are packaged in 16-SOIC. The primary difference is product status (Active vs. Obsolete) and packaging format. No circuit modifications are required.

Q: What are the key differences between MAX964ESE and TLC3704 series devices?

A: The primary differences are package pin count (16-SOIC vs. 14-SOIC/14-TSSOP), supply voltage range (2.7V ~ 5.5V vs. 3V ~ 16V), propagation delay (7ns vs. 4.5µs), and operating temperature range. TLC3704 devices feature lower input bias current (5pA vs. 15µA) and higher quiescent current. Substitution requires PCB layout redesign due to different pin configurations.

Q: Is TLC3704 suitable for high-speed comparison applications?

A: No. The TLC3704 series has a maximum propagation delay of 4.5µs, significantly slower than the MAX964ESE (7ns). For applications requiring fast signal comparison, MAX964ESE or MAX964ESE+ are the appropriate choices.

Q: Can TLC3704 devices operate across the full 2.7V ~ 5.5V range of MAX964ESE?

A: Yes. TLC3704 devices operate across 3V ~ 16V, which encompasses the MAX964ESE range of 2.7V ~ 5.5V. However, the minimum supply voltage for TLC3704 is 3V, not 2.7V. Applications requiring operation below 3V must use MAX964ESE or MAX964ESE+.

Q: Which substitute is appropriate for automotive applications?

A: TLC3704QDRG4Q1 is the only substitute option with automotive qualification (AEC-Q100) and extended operating temperature range (-40°C ~ 125°C). This device is suitable for automotive and industrial temperature environments.

Q: What PCB layout considerations apply when substituting TLC3704 for MAX964ESE?

A: TLC3704 devices are available in 14-pin packages (14-SOIC or 14-TSSOP) compared to MAX964ESE's 16-SOIC. PCB layout must be modified to accommodate the different pin count and package footprint. Verify pin assignments and signal routing before implementation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MAX964ESE+, TLC3704CDR, TLC3704CPWR, and TLC3704QDRG4Q1 are all ROHS3 compliant, meeting environmental and regulatory requirements equivalent to the original MAX964ESE.
