MAX968ESA Equivalent & Substitute Parts

Part Overview

The MAX968ESA is a dual-channel window comparator with open-drain, rail-to-rail output configuration manufactured by Analog Devices Inc./Maxim Integrated. This linear integrated circuit operates across a supply voltage range of 1.6V to 5.5V and is housed in an 8-SOIC surface-mount package. The device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX968ESA is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters define the substitution criteria:

  • Comparator type and channel count (dual-channel window configuration)
  • Output stage characteristics (open-drain, rail-to-rail topology)
  • Supply voltage operating range (1.6V ~ 5.5V)
  • Input offset voltage specification (7mV @ 5.5V maximum)
  • Input bias current specification (0.05µA @ 5.5V maximum)
  • Quiescent current specification (16µA maximum)
  • Common-mode and power-supply rejection ratios (56.48dB CMRR, 80dB PSRR typical)
  • Propagation delay specification (20µs maximum)
  • Hysteresis specification (±1mV)
  • Operating temperature range (-40°C ~ 85°C)
  • Package configuration (8-SOIC surface-mount)

Only parts meeting all specified parameters across electrical performance, thermal range, and physical packaging qualify as direct substitutes.

Engineering Selection Recommendations

The MAX968ESA+ serves as the direct substitute for the obsolete MAX968ESA. Both parts maintain identical electrical specifications and mechanical packaging, ensuring functional interchangeability in circuit applications. The primary distinction is product status: the MAX968ESA is obsolete, while the MAX968ESA+ is active and currently manufactured.

For new designs or production continuity, the MAX968ESA+ is the appropriate selection. Both parts carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can MAX968ESA+ directly replace MAX968ESA in existing designs?

A: Yes. The MAX968ESA+ is electrically and mechanically identical to the MAX968ESA. All electrical parameters, operating ranges, and package specifications are equivalent, enabling direct substitution without circuit modification.

Q: What is the primary reason to transition from MAX968ESA to MAX968ESA+?

A: The MAX968ESA is classified as obsolete. The MAX968ESA+ is the active production equivalent, ensuring long-term availability and supply chain continuity.

Q: Are there packaging differences between these parts?

A: Both parts use the 8-SOIC surface-mount package with identical dimensions (0.154" width, 3.90mm). The MAX968ESA is supplied in standard packaging, while the MAX968ESA+ is supplied in tube packaging. This distinction does not affect electrical performance or mechanical compatibility.

Q: Do both parts meet current compliance standards?

A: Yes. Both MAX968ESA and MAX968ESA+ are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: What is the moisture sensitivity rating for these parts?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
