Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74HC164D14 are qualified based on the following critical parameters that determine functional and mechanical interchangeability:

• Logic Type and Function: Shift Register with Serial to Parallel conversion capability
• Bit Configuration: 1 Element, 8 Bits per Element
• Output Characteristics: Push-Pull output type
• Electrical Specifications: Supply voltage range 2V ~ 6V and operating temperature range -40°C ~ 125°C
• Physical Compatibility: 14-pin DIP package with 0.300" (7.62mm) pitch
• Series Compatibility: 74HC logic family
• Regulatory Compliance: ROHS3 Compliant and REACH Unaffected status

The SN74HC164N from Texas Instruments meets all these criteria and is therefore a direct parametric equivalent.
