MAX932EPA Equivalent & Substitute Parts

Part Overview

The MAX932EPA is a dual comparator with integrated voltage reference, manufactured by Analog Devices Inc./Maxim Integrated. This device combines two independent comparators with CMOS and TTL output capability in an 8-pin DIP package. The MAX932EPA is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The LTC1442 series provides direct functional equivalence with active product status and extended availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX932EPA is based on the following critical parameters that must remain compatible:

• Functional Type: Dual comparator with voltage reference, CMOS/TTL output
• Package Format: 8-pin DIP through-hole mounting (0.300", 7.62mm)
• Electrical Characteristics: Input offset voltage, hysteresis, CMRR/PSRR, and output type
• Supply Voltage Range: Compatibility with single and dual supply operation
• Pin Configuration: Identical pinout for direct socket replacement

The LTC1442CN8#PBF and LTC1442IN8#PBF meet these substitution criteria. Both devices maintain the same functional architecture, package format, and core electrical specifications. The primary differences are product status (active vs. obsolete) and operating temperature range, which do not affect substitution eligibility for applications within the specified temperature windows.

Parameter Comparison

Engineering Selection Recommendations

LTC1442IN8#PBF is the primary substitute for MAX932EPA applications. This device maintains identical operating temperature range (-40°C ~ 85°C), ensuring compatibility with designs requiring extended temperature operation. Both devices are ROHS3 compliant and REACH unaffected, meeting modern environmental and regulatory requirements. The LTC1442IN8#PBF is actively manufactured with 874 units in stock, providing supply continuity.

LTC1442CN8#PBF serves as an alternative for applications operating within the 0°C ~ 70°C temperature window. This variant offers the same functional and electrical characteristics as the MAX932EPA within its specified temperature range. The LTC1442CN8#PBF is also actively produced with 1000 units available, supporting high-volume requirements.

Both LTC1442 variants feature improved output current capability (40mA typical vs. 0.015mA), which enhances drive capability for downstream logic circuits. Propagation delay increases marginally (15µs vs. 12µs), which remains acceptable for most timing-critical applications. The slightly reduced minimum supply voltage (2V vs. 2.5V single supply) expands operational flexibility.

Frequently Asked Questions (FAQ)

Q: Can LTC1442CN8#PBF replace MAX932EPA in all applications?

A: LTC1442CN8#PBF is suitable for applications operating within 0°C ~ 70°C. For designs requiring -40°C ~ 85°C operation, use LTC1442IN8#PBF instead.

Q: Are the pin configurations identical between MAX932EPA and LTC1442 variants?

A: Yes. Both devices use 8-pin DIP packaging with identical pinout, enabling direct socket replacement without circuit modification.

Q: What is the impact of increased output current on circuit design?

A: LTC1442 series provides 40mA typical output current compared to MAX932EPA's 0.015mA. This improvement allows direct driving of standard TTL/CMOS logic without additional buffer stages, simplifying circuit design.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both LTC1442CN8#PBF and LTC1442IN8#PBF are ROHS3 compliant and REACH unaffected, matching MAX932EPA compliance status.

Q: How does the propagation delay difference affect timing-sensitive circuits?

A: LTC1442 variants exhibit 15µs maximum propagation delay versus MAX932EPA's 12µs. The 3µs difference is negligible for most applications. Verify timing margins in circuits with sub-microsecond timing requirements.

Q: What is the supply voltage compatibility range?

A: LTC1442 series operates from 2V ~ 11V (single supply) or ±1V ~ 5.5V (dual supply), compared to MAX932EPA's 2.5V ~ 11V or ±1.25V ~ 5.5V. LTC1442 provides expanded lower voltage operation.
