MAX933CUA-T Equivalent & Substitute Parts

Part Overview

The MAX933CUA-T is a dual comparator with integrated voltage reference, manufactured by Analog Devices Inc./Maxim Integrated. This CMOS/TTL output comparator operates across a wide supply voltage range (2.5V ~ 11V single supply, ±1.25V ~ 5.5V dual supply) and is housed in an 8-TSSOP/8-MSOP surface mount package. The device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution of the MAX933CUA-T is determined by strict equivalence across the following critical parameters:

• Functional Type: Dual comparator with integrated voltage reference
• Output Configuration: CMOS/TTL compatible outputs
• Supply Voltage Range: 2.5V ~ 11V (single supply) and ±1.25V ~ 5.5V (dual supply)
• Electrical Performance: Input offset voltage (10mV @ 5V), quiescent current (6µA max), propagation delay (12µs max), hysteresis (50mV)
• Package Compatibility: 8-TSSOP/8-MSOP surface mount package with 0.118" (3.00mm) width
• Compliance Standards: ROHS3 compliant, MSL Level 1

The MAX933CUA+T qualifies as a direct substitute based on identical electrical specifications, package dimensions, and functional characteristics. The primary distinction is packaging format and product status.

Parameter Comparison
