CD74HC157M96 Equivalent & Substitute Parts

Part Overview

The CD74HC157M96 is a 4 x 2:1 multiplexer logic integrated circuit manufactured by Texas Instruments in 16-SOIC surface mount packaging. This device functions as a data selector, routing one of two input signals to a single output based on control logic. The part is currently in active production status with 3540 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when sourcing from multiple manufacturers is needed for supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC157M96 is determined by the following critical parameters:

• Circuit configuration: 4 x 2:1 multiplexer topology
• Package type: 16-SOIC surface mount form factor
• Voltage supply range: 2V ~ 6V single supply operation
• Operating temperature range: -55°C ~ 125°C minimum
• RoHS and REACH compliance status
• Moisture sensitivity level: MSL 1

Substitute parts must maintain identical circuit functionality, compatible package dimensions, and overlapping electrical specifications. Variations in output current ratings (5.2mA vs 7.8mA) are acceptable within the 74HC logic family when the application does not require specific current matching. Packaging format differences (Tape & Reel, Bulk, Tube, Cut Tape) do not affect electrical compatibility but impact procurement and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compatibility)

The 74HC157D,653 (Nexperia USA Inc.) and 74HC157D,652 (NXP Semiconductors) are direct functional equivalents with active product status. Both maintain the -40°C to 125°C operating range, which encompasses the CD74HC157M96 specification. The 74HC157D,653 in Tape & Reel format aligns with the original packaging preference. NXP's 74HC157D,652 offers the highest inventory availability (32196 units) in bulk packaging, suitable for high-volume manufacturing.

Secondary Substitutes (Active Status, Extended Current Rating)

The MC74HC157ADR2G and MC74HC157ADG (onsemi) provide active product status with extended output current ratings of 7.8mA versus the original 5.2mA. These parts are suitable for applications requiring higher drive capability. The MC74HC157ADR2G maintains Tape & Reel packaging, while MC74HC157ADG is supplied in Tube format. Both support the full -55°C to 125°C temperature range.

Avoid

The CD74HC157MT (Texas Instruments) carries Last Time Buy status, indicating discontinued production. The NLV74HC157ADR2G (onsemi) is marked Obsolete and should not be selected for new designs despite current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can I substitute the CD74HC157M96 with any 74HC157 variant?

A: Yes, provided the substitute maintains the 4 x 2:1 circuit configuration, 16-SOIC package, 2V to 6V supply voltage, and compatible operating temperature range. All listed substitutes meet these criteria.

Q: Does the difference in output current (5.2mA vs 7.8mA) affect compatibility?

A: Output current differences do not affect functional compatibility. The higher current rating of onsemi parts (7.8mA) provides additional drive capability without compromising the original circuit design. Selection depends on application load requirements.

Q: What is the impact of packaging format differences?

A: Packaging format (Tape & Reel, Bulk, Tube, Cut Tape) affects procurement and assembly processes but not electrical performance. Tape & Reel and Cut Tape formats are optimized for automated pick-and-place assembly. Bulk and Tube formats require manual handling or alternative assembly methods.

Q: Why should I avoid the NLV74HC157ADR2G?

A: The NLV74HC157ADR2G is marked Obsolete, indicating end-of-life status. While inventory exists, future availability is not guaranteed. Active status parts ensure long-term supply chain reliability.

Q: Are there temperature range considerations for substitution?

A: The CD74HC157M96 operates from -55°C to 125°C. NXP's 74HC157D variants operate from -40°C to 125°C, which is acceptable for most applications but may not meet requirements for extended low-temperature operation below -40°C. Verify application requirements before selection.

Q: Do all substitutes carry the same compliance certifications?

A: All listed substitutes are RoHS3 compliant and REACH unaffected. Moisture sensitivity level is MSL 1 (Unlimited) across all parts, indicating no special storage or handling requirements.
