MAX154ACNG Equivalent & Substitute Parts

Part Overview

The MAX154ACNG is an 8-bit flash analog-to-digital converter manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring 4 single-ended inputs with integrated multiplexer and sample-and-hold functionality. The device operates at a 400 kHz sampling rate and is housed in a 24-DIP package.

The MAX154ACNG is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance or redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX154ACNG is determined by strict equivalence across the following critical parameters: resolution (8 bits), sampling rate (400 kHz), number of inputs (4), input configuration (single-ended), data interface (parallel), architecture (flash), reference type (internal), supply voltages (5V analog and digital), operating temperature range (0°C to 70°C), and package type (24-DIP through-hole).

Two substitute parts meet these criteria:

MAX154ACNG+ — Direct manufacturer equivalent with identical electrical and mechanical specifications. Differs only in packaging format (tube) and product status (active vs. obsolete).

MAX154BCNG+ — Parametric equivalent with identical electrical specifications and package configuration. Differs in product status (active) and RoHS compliance certification level.

Parameter Comparison

Engineering Selection Recommendations

For new designs or system redesigns, MAX154ACNG+ or MAX154BCNG+ are preferred selections due to active product status and ROHS3 compliance certification. Both parts maintain full electrical and mechanical compatibility with the original MAX154ACNG specification.

The MAX154ACNG+ provides direct equivalence with identical part designation structure and active availability. The MAX154BCNG+ offers equivalent performance with active status and compliance certification.

For legacy system maintenance where the original MAX154ACNG is required, MAX154ACNG+ serves as the direct replacement. Both substitute parts are available in tube packaging and maintain the same 24-DIP through-hole form factor, enabling direct board-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can MAX154ACNG+ be used as a direct replacement for MAX154ACNG?

A: Yes. MAX154ACNG+ is electrically and mechanically identical to MAX154ACNG across all specified parameters. The primary difference is product status (active vs. obsolete) and packaging format (tube). Both are pin-compatible 24-DIP devices with identical electrical performance.

Q: What is the difference between MAX154ACNG+ and MAX154BCNG+?

A: Both parts are parametric equivalents with identical electrical specifications and 24-DIP package configuration. The designation suffix indicates different product lines within the MAX154 family. Both are active products with ROHS3 compliance certification.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. All three parts share identical pin configurations, electrical characteristics, supply voltage requirements (5V analog and digital), operating temperature range (0°C to 70°C), and 24-DIP through-hole mounting. Direct board-level substitution is supported without circuit modification.

Q: Why is the original MAX154ACNG classified as obsolete?

A: The MAX154ACNG has been superseded by active product variants (MAX154ACNG+ and MAX154BCNG+) that offer improved compliance certifications and continued manufacturer support. The obsolete status reflects discontinuation of this specific variant in favor of active alternatives.

Q: What packaging formats are available for substitute parts?

A: Both MAX154ACNG+ and MAX154BCNG+ are supplied in tube packaging. The original MAX154ACNG packaging format is not specified in the provided data. All three parts use the same 24-DIP (0.300", 7.62mm) case style for through-hole mounting.
