CD74HC157MT Equivalent & Substitute Parts

Part Overview

The CD74HC157MT is a 4 x 2:1 multiplexer logic integrated circuit manufactured by Texas Instruments in 16-SOIC surface mount packaging. This part is classified as Last Time Buy, indicating limited availability from the original manufacturer. The CD74HC157MT operates as a data selector with single supply voltage capability, making it suitable for digital signal routing and selection applications in logic circuits. Due to its Last Time Buy status, identifying functionally equivalent alternatives from active manufacturers is essential for design continuity and long-term component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC157MT is determined by strict equivalence across the following parameters: circuit configuration (4 x 2:1 multiplexer), package type (16-SOIC), supply voltage range (2V to 6V), and operating temperature range. The 74HC series base product number ensures functional compatibility across all identified substitutes. Output current specifications and mounting type must remain consistent with the original part to ensure drop-in replacement capability.

Substitute parts are grouped into three categories based on manufacturer and product status: parametric equivalents from alternative manufacturers, direct manufacturer alternatives from active suppliers, and manufacturer-recommended alternatives with enhanced specifications or certifications.

Parameter Comparison

Engineering Selection Recommendations

For new designs and long-term production, select from parts with Active product status: 74HC157D,653 (Nexperia USA Inc., Tape & Reel), MC74HC157ADR2G (onsemi, Tape & Reel), 74HC157D,652 (NXP Semiconductors, Bulk), or 74HC157D-Q100,118 (NXP USA Inc., automotive-qualified).

The 74HC157D,653 provides direct functional equivalence with identical output current specifications (5.2mA/5.2mA) and is available in Tape & Reel packaging, matching the original CD74HC157MT format. This part is ROHS3 compliant and carries REACH Unaffected status.

The MC74HC157ADR2G and MC74HC157ADG from onsemi are functionally equivalent with higher output current capability (7.8mA/7.8mA) and extended temperature range (-55°C to 125°C), providing enhanced performance margins. Both are ROHS3 compliant and REACH Unaffected.

The 74HC157D-Q100,118 from NXP USA Inc. includes AEC-Q100 automotive qualification, suitable for applications requiring automotive-grade components.

Avoid CD74HC157M96 (Harris Corporation, Obsolete) and NLV74HC157ADR2G (onsemi, Obsolete) for new designs due to discontinued status.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC157MT be directly replaced with any of the listed substitutes?

A: Yes, all listed substitutes maintain the 4 x 2:1 multiplexer circuit configuration, 16-SOIC package, 2V to 6V supply voltage range, and surface mount mounting type. Physical and electrical compatibility is confirmed for drop-in replacement. Verify packaging format (Tape & Reel, Bulk, or Tube) matches your assembly requirements.

Q: What is the difference between the onsemi MC74HC157ADR2G and the NXP 74HC157D,653?

A: Both are functionally equivalent 4 x 2:1 multiplexers in 16-SOIC packaging. The MC74HC157ADR2G has higher output current (7.8mA vs. 5.2mA) and supports the full -55°C to 125°C temperature range. The 74HC157D,653 matches the original CD74HC157MT output current specification (5.2mA) and operates from -40°C to 125°C. Selection depends on your circuit's current requirements and temperature operating range.

Q: Why is the CD74HC157M96 listed if it is obsolete?

A: The CD74HC157M96 is included for reference as a parametric equivalent with identical electrical specifications to the CD74HC157MT. However, its Obsolete status makes it unsuitable for new designs or long-term sourcing. Active alternatives should be prioritized.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel, Bulk, and Tube packaging formats contain identical die and electrical specifications. Packaging format selection is determined by assembly process requirements and volume needs, not electrical performance.

Q: Is the 74HC157D-Q100,118 suitable for non-automotive applications?

A: Yes. The AEC-Q100 automotive qualification indicates enhanced reliability and testing standards. This part is fully compatible with non-automotive applications and provides additional quality assurance.

Q: What is the minimum operating temperature difference between substitutes?

A: The CD74HC157MT and most onsemi alternatives operate from -55°C to 125°C. NXP parts (74HC157D,652, 74HC157D,653, 74HC157D-Q100,118) operate from -40°C to 125°C, a 15°C difference at the lower temperature limit. Verify your application's minimum operating temperature requirement before selection.
