SN74LVC157ANSRE4 Equivalent & Substitute Parts

Part Overview

The SN74LVC157ANSRE4 is a 4 x 2:1 multiplexer logic integrated circuit manufactured by Texas Instruments in a 16-SOIC surface mount package. 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 discontinued at DiGi Electronics, making identification of equivalent substitute components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74LVC157ANSRE4 is determined by strict equivalence across the following critical parameters:

• Multiplexer circuit configuration (4 x 2:1)
• Output current specifications (24mA high and low)
• Supply voltage range (2V ~ 3.6V)
• Operating temperature range (-40°C ~ 85°C)
• Package type (16-SOIC surface mount)
• Compliance certifications (RoHS3, REACH Unaffected)

The SN74LVC157ANSR meets all these criteria and serves as the direct manufacturer-recommended substitute. The primary distinction between the main part and substitute is product status and packaging format availability.

Parameter Comparison

Engineering Selection Recommendations

The SN74LVC157ANSR is the direct substitute for the SN74LVC157ANSRE4. Both parts are manufactured by Texas Instruments with identical electrical specifications, package dimensions, and compliance certifications. The SN74LVC157ANSR is currently in active production status, ensuring long-term availability and supply chain continuity. Selection of the SN74LVC157ANSR eliminates obsolescence risk while maintaining full functional and mechanical compatibility with designs originally specified for the SN74LVC157ANSRE4.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC157ANSR be used as a direct replacement for the SN74LVC157ANSRE4?

A: Yes. Both parts are electrically and mechanically identical. The SN74LVC157ANSR differs only in product status (active versus discontinued) and packaging format availability. Pin configuration, electrical performance, and package dimensions are equivalent.

Q: What is the difference between the SN74LVC157ANSRE4 and SN74LVC157ANSR?

A: The SN74LVC157ANSRE4 is discontinued at DiGi Electronics, while the SN74LVC157ANSR remains in active production. The "E4" suffix in the original part number indicates a specific packaging or distribution format. The core logic device is identical.

Q: Are there any voltage or temperature limitations when substituting these parts?

A: No. Both parts operate within the same voltage supply range (2V ~ 3.6V) and temperature range (-40°C ~ 85°C). Substitution does not introduce any operational constraints.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SN74LVC157ANSRE4 and SN74LVC157ANSR are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited).

Q: What is the package type for these multiplexer ICs?

A: Both parts use a 16-SOIC (Small Outline Integrated Circuit) surface mount package with a width of 0.209 inches (5.30mm). This package type is standard for 16-pin logic multiplexers in this series.
