Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74LS164DRE4 is determined by strict equivalence across the following parameters:

• Logic type and function (Shift Register, Serial to Parallel conversion)
• Bit configuration (1 Element, 8 Bits per Element)
• Output type (Push-Pull)
• Electrical specifications (4.75V ~ 5.25V supply, 0°C ~ 70°C operating range)
• Package and pinout (14-SOIC with identical mechanical dimensions)
• Series classification (74LS)

The SN74LS164DR meets all these criteria and qualifies as a parametric equivalent. Both parts share identical electrical and mechanical specifications, with the primary distinction being packaging format and product availability status.
