DM74164N Equivalent & Substitute Parts

Part Overview

The DM74164N is an 8-bit serial-in/parallel-out shift register manufactured by onsemi, housed in a 14-DIP package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The shift register performs serial-to-parallel data conversion with push-pull output configuration, operating within the 4.75V to 5.25V supply voltage range and 0°C to 70°C temperature specifications typical of 7400 series logic devices.

Substitute Part Grouping Explanation

Substitute parts for the DM74164N are qualified based on strict parameter matching across the following criteria:

• Logic Type: Shift Register (1 element, 8-bit configuration)
• Function: Serial to Parallel conversion
• Output Type: Push-Pull
• Voltage Supply Range: 4.75V ~ 5.25V
• Operating Temperature Range: 0°C ~ 70°C
• Package: 14-DIP (0.300", 7.62mm)
• Mounting: Through Hole

The identified substitutes belong to the 74LS series, which maintains full electrical and mechanical compatibility with the original DM74164N while offering active product status and modern compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both SN74LS164N and SN74LS164NE4 are direct functional equivalents to the DM74164N. Selection between these substitutes should be based on the following factors:

SN74LS164N is recommended for applications requiring standard tube packaging and maximum inventory availability (15,423 units in stock). This part maintains active product status with ROHS3 compliance certification.

SN74LS164NE4 is recommended for applications where specific device package designation (14-PDIP) is required by procurement or design specifications. This part also maintains active product status with ROHS3 compliance certification and is available in smaller quantities (1,071 units in stock).

Both substitutes are REACH Unaffected and carry the same ECCN and HTSUS classifications as the original DM74164N, ensuring regulatory compliance across international markets.

Frequently Asked Questions (FAQ)

Q: Can SN74LS164N or SN74LS164NE4 be used as direct replacements for DM74164N in existing designs?

A: Yes. Both parts are parametrically equivalent across all critical electrical and mechanical specifications: 8-bit serial-to-parallel shift register function, push-pull output, 4.75V–5.25V supply voltage, 0°C–70°C operating temperature, and 14-DIP package form factor. No circuit modifications are required.

Q: What is the difference between SN74LS164N and SN74LS164NE4?

A: Both parts are functionally identical. The primary difference is packaging designation: SN74LS164N uses tube packaging, while SN74LS164NE4 specifies 14-PDIP supplier device package. Selection depends on procurement requirements and inventory availability.

Q: Why is the DM74164N listed as obsolete?

A: The DM74164N is an older 7400 series component. The 74LS series variants (SN74LS164N and SN74LS164NE4) represent the active, modern equivalent with improved compliance certifications and continued manufacturing support.

Q: Are there any compliance differences between the original and substitute parts?

A: The substitute parts (SN74LS164N and SN74LS164NE4) carry ROHS3 compliance certification, whereas the original DM74164N does not specify RoHS status. All three parts are REACH Unaffected and share identical ECCN and HTSUS classifications.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. All three parts use the same 14-DIP (0.300", 7.62mm) through-hole package, enabling direct pin-compatible substitution without PCB layout modifications.
