MAX964EEE Equivalent & Substitute Parts

Part Overview

The MAX964EEE is a 4-channel general-purpose comparator manufactured by Analog Devices Inc./Maxim Integrated, designed for CMOS and TTL applications. This device operates across a 2.7V to 5.5V supply range and features low input offset voltage (1.5mV @ 5V) and fast propagation delay (7ns). The MAX964EEE is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility while meeting current availability and compliance standards.

Substitute Part Grouping Explanation

Substitution of the MAX964EEE is determined by the following critical parameters:

Functional Equivalence Criteria:

Number of Elements: 4 channels required
Output Type: CMOS and/or TTL compatible output
Voltage Supply Range: Must encompass or exceed 2.7V ~ 5.5V
Input Offset Voltage: Lower or equal to 1.5mV @ specified voltage
Input Bias Current: Lower or equal to 15µA @ specified voltage
Quiescent Current: Lower or equal to 9mA
Operating Temperature Range: Must cover -40°C ~ 85°C minimum

Package Compatibility:

Surface mount packages (SSOP, SOIC, TSSOP) are direct mechanical substitutes
Through-hole packages (DIP, PDIP) represent functional alternatives for different assembly methods
Pin count and footprint must accommodate circuit board layout

Substitute parts are grouped by package type and product status (Active vs. Last Time Buy), with compliance certifications (RoHS3) as secondary selection criteria.

Engineering Selection Recommendations

Direct Replacement (Same Package): MAX964EEE+ is the direct successor to MAX964EEE, maintaining identical electrical specifications and 16-SSOP packaging. This part is Active status with RoHS3 compliance, making it the preferred choice for designs requiring no layout modifications.

Alternative Substitutes (Different Packages):

TLC3704QDRQ1 (Texas Instruments, 14-SOIC) is recommended for new designs requiring extended temperature operation (-40°C ~ 125°C) and automotive qualification (AEC-Q100). This part is Active status with superior quiescent current performance (175µA vs. 9mA).

TLC3704ID (Texas Instruments, 14-SOIC) provides functional equivalence with Last Time Buy status. Operating temperature range (-40°C ~ 85°C) matches the original specification. Quiescent current is 125µA.

TLC3704IN (Texas Instruments, 14-DIP) is suitable for through-hole assembly applications. Last Time Buy status indicates limited future availability.

TS3704IDT (STMicroelectronics, 14-SOIC) offers the lowest input bias current (1pA @ 5V) and quiescent current (25µA) among all substitutes. Active status ensures long-term availability. Dual supply operation (±1.35V ~ 8V) provides additional flexibility.

Compliance Consideration: All substitute parts are RoHS3 compliant, whereas the original MAX964EEE is non-compliant. This is a critical factor for new production and regulated applications.

Frequently Asked Questions (FAQ)

Q: Can MAX964EEE+ be used as a direct replacement for MAX964EEE? A: Yes. MAX964EEE+ maintains identical electrical specifications (supply voltage, input offset, bias current, quiescent current, propagation delay, hysteresis) and uses the same 16-SSOP package. The primary difference is product status (Active vs. Obsolete) and RoHS3 compliance.

Q: What are the key differences between MAX964EEE and TLC3704 variants? A: TLC3704 parts feature lower input bias current (5pA vs. 15µA), significantly lower quiescent current (100-175µA vs. 9mA), and higher CMRR (84dB vs. 80dB). However, TLC3704 variants use 14-pin packages (TSSOP, SOIC, DIP) instead of 16-SSOP, requiring circuit board redesign. Input offset voltage is higher (5mV @ 10V vs. 1.5mV @ 5V).

Q: Which substitute is best for automotive applications? A: TLC3704QDRQ1 is specifically qualified for automotive use (AEC-Q100) with extended temperature range (-40°C ~ 125°C). This part is Active status and available in 14-SOIC package.

Q: Can I use a through-hole package (TLC3704IN) instead of surface mount? A: Yes, if your assembly process supports through-hole mounting. TLC3704IN provides functional equivalence with -40°C ~ 85°C operating range. Note that this part has Last Time Buy status, indicating limited future availability.

Q: What is the impact of different package types on circuit design? A: Package changes require PCB layout modifications. MAX964EEE uses 16-SSOP (0.154" width), while TLC3704 variants use 14-pin packages (14-TSSOP, 14-SOIC, or 14-DIP). Pin assignments may differ; verify pinout compatibility before substitution.

Q: Why do substitute parts have lower quiescent current than the original? A: TLC3704 and TS3704 are newer designs with improved power efficiency. Lower quiescent current (25-175µA vs. 9mA) reduces power dissipation, though this does not affect functional compatibility for most applications.

Q: Is TS3704IDT compatible with dual supply operation? A: Yes. TS3704IDT supports both single supply (2.7V ~ 16V) and dual supply (±1.35V ~ 8V) operation, providing additional design flexibility compared to single-supply-only alternatives.

Q: What does "Last Time Buy" status mean? A: Last Time Buy indicates the manufacturer will discontinue the part after a specified date. Existing inventory may be available, but long-term supply is not guaranteed. For new designs, Active status parts (MAX964EEE+, TLC3704QDRQ1, TS3704IDT) are preferred.
