SN74LS164NE4 Equivalent & Substitute Parts

Part Overview

The SN74LS164NE4 is an 8-bit serial-in parallel-out shift register manufactured by Texas Instruments, classified within the 74LS logic family. This component converts serial data input into parallel output across 8 bits, functioning as a fundamental building block in digital logic circuits requiring data serialization and timing control. The part is currently in active production status with 1071 units available in new original stock. Substitute parts are identified when equivalent electrical parameters, mechanical packaging, and compliance certifications align with the original specification, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LS164NE4 is determined by strict alignment across the following critical parameters:

Electrical Parameters: Logic type (Shift Register), number of bits per element (8), function (Serial to Parallel), output type (Push-Pull), supply voltage range (4.75V ~ 5.25V), and operating temperature range (0°C ~ 70°C).

Mechanical Parameters: Package type (14-DIP), physical dimensions (0.300", 7.62mm), and mounting method (Through Hole).

Compliance Parameters: RoHS3 compliance status, REACH status, and ECCN classification.

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The SN74LS164N qualifies as a parametric equivalent based on identical electrical specifications, mechanical packaging, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SN74LS164N serves as a direct parametric equivalent to the SN74LS164NE4. Both components are manufactured by Texas Instruments, maintain identical electrical specifications across supply voltage and operating temperature ranges, and share the same 14-DIP through-hole package configuration. Both parts carry active product status and maintain ROHS3 compliance with REACH unaffected designation, confirming regulatory alignment for current manufacturing and deployment standards.

Selection between these parts is determined by availability and packaging format (tube packaging is specified for both). The SN74LS164N currently maintains higher inventory availability at 15423 units compared to 1071 units for the SN74LS164NE4, making it a viable alternative when supply constraints exist for the original part number.

Frequently Asked Questions (FAQ)

Q: Can the SN74LS164N replace the SN74LS164NE4 in existing circuit designs?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, supply voltage requirements (4.75V ~ 5.25V), operating temperature range (0°C ~ 70°C), and 14-DIP package configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between SN74LS164NE4 and SN74LS164N?

A: The primary difference is the packaging designation suffix. Both parts are 8-bit serial-in parallel-out shift registers from Texas Instruments with identical functional specifications. The "NE4" and "N" suffixes indicate different packaging or distribution formats, but electrical and mechanical parameters remain equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both the SN74LS164NE4 and SN74LS164N are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronics manufacturing and deployment.

Q: What mounting method is required for these parts?

A: Both parts utilize through-hole mounting in a 14-DIP package with 0.300-inch (7.62mm) pitch. Installation requires standard through-hole PCB assembly processes.

Q: Can these parts operate at different supply voltages?

A: Both parts operate within the identical supply voltage range of 4.75V ~ 5.25V. Operation outside this range is not supported and may result in functional failure or component damage.
