MM74HC157MX Equivalent & Substitute Parts

Part Overview

The MM74HC157MX is a 4 x 2:1 multiplexer logic IC manufactured by onsemi in a 16-SOIC surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The MM74HC157MX operates across a 2V to 6V supply range with output currents of 5.2mA (both high and low), suitable for general-purpose logic multiplexing applications in industrial and commercial environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MM74HC157MX is determined by the following critical parameters:

• Circuit configuration (4 x 2:1 multiplexer function)
• Package type (16-SOIC surface mount)
• Voltage supply compatibility (2V ~ 6V range or compatible subset)
• Operating temperature range (minimum -40°C, maximum 85°C or broader)
• Output current capability (5.2mA or higher for both high and low states)
• Single supply voltage source requirement

Parts are grouped into three categories based on their relationship to the main part: similar function with different electrical characteristics, direct equivalents from alternative manufacturers, and upgraded versions with enhanced specifications or compliance status.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, active product status parts are preferred. The MC74HC157ADG and MC74HC157ADR2G from onsemi provide identical electrical specifications to the MM74HC157MX with extended operating temperature range (-55°C ~ 125°C) and ROHS3 compliance. These parts maintain the same 2V to 6V supply voltage and 4 x 2:1 multiplexer configuration.

The SN74HC157DR from Texas Instruments is an active product offering equivalent electrical performance with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). This part matches the original operating temperature range of -40°C ~ 85°C.

For applications requiring identical output current specifications (5.2mA), the 74HC157D,652 and 74HC157D,653 from NXP Semiconductors / Nexperia USA Inc. are active products with extended temperature range (-40°C ~ 125°C) and ROHS3 compliance.

The 74VHC157MX from Fairchild Semiconductor is an active alternative with higher output current capability (8mA) but operates within a narrower voltage supply range (2V ~ 5.5V). This part is suitable only for applications operating within this reduced voltage window.

Frequently Asked Questions (FAQ)

Q: Can the MM74HC157MX be directly replaced with any of these substitute parts?

A: Direct replacement is possible with parts sharing identical package (16-SOIC), circuit configuration (4 x 2:1), and voltage supply range (2V ~ 6V). The MC74HC157ADG, MC74HC157ADR2G, SN74HC157DR, 74HC157D,652, and 74HC157D,653 meet these criteria. Verify your application's operating temperature requirements before selection.

Q: What is the difference between MC74HC157ADG and MC74HC157ADR2G?

A: Both parts are electrically identical with the same 4 x 2:1 multiplexer configuration, voltage supply range, and output current specifications. The primary difference is packaging: MC74HC157ADG is supplied in Tube packaging, while MC74HC157ADR2G is supplied in Tape & Reel (TR) format. Select based on your procurement and assembly requirements.

Q: Is the 74VHC157MX a suitable replacement?

A: The 74VHC157MX is functionally equivalent but operates within a narrower voltage supply range (2V ~ 5.5V) compared to the MM74HC157MX (2V ~ 6V). Use this part only if your application operates entirely within the 2V to 5.5V window. The 74VHC157MX offers higher output current (8mA versus 5.2mA).

Q: Why are some substitute parts listed as obsolete?

A: Obsolete parts (NLV74HC157ADR2G, CD74HC157M96, CD74HC157M) are included for reference and existing inventory management. For new designs, select from active status parts to ensure long-term supply availability and manufacturer support.

Q: What compliance certifications should I verify?

A: Active substitute parts carry ROHS3 compliance and REACH Unaffected status. Verify these certifications match your application requirements. All listed parts share the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications as the original MM74HC157MX.
