Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74AC153PC is determined by the following critical parameters:

• Circuit configuration: 2 x 4:1 multiplexer topology
• Package type: 16-DIP through-hole form factor
• Output current capability: 24mA high and low
• Supply voltage compatibility: Single supply operation
• Base product series: 74AC logic family

The CD74AC153E qualifies as a direct substitute based on identical circuit configuration, matching package specification, equivalent output current ratings, and compatible supply voltage operation within the 74AC logic family. Both parts implement the same functional multiplexer architecture and are pin-compatible in 16-DIP packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the 74AC153PC and CD74AC153E are obsolete components. Selection between these parts should be based on the following factors:

Voltage Supply Requirements: The CD74AC153E supports a lower minimum supply voltage (1.5V) compared to the 74AC153PC (2V). If your application operates at supply voltages below 2V, the CD74AC153E is the appropriate choice.

Temperature Operating Range: The CD74AC153E provides an extended operating temperature range (-55°C to 125°C) versus the 74AC153PC (-40°C to 85°C). Applications requiring operation at temperatures below -40°C or above 85°C require the CD74AC153E.

Compliance Status: The CD74AC153E is marked as RoHS non-compliant. If RoHS compliance is a system requirement, verify that your application permits non-compliant components or consider alternative modern multiplexer solutions.

Packaging and Availability: Both parts use identical 16-DIP through-hole packaging. Verify PCB layout compatibility and soldering process requirements for through-hole components.

Frequently Asked Questions (FAQ)

Q: Are the 74AC153PC and CD74AC153E pin-compatible? A: Yes. Both components use the 16-DIP package with identical pinout. Direct socket substitution is possible without PCB modification.

Q: Can I use the CD74AC153E as a drop-in replacement for the 74AC153PC? A: Yes, provided your application operates within the CD74AC153E's voltage supply range (1.5V ~ 5.5V) and temperature range (-55°C ~ 125°C). The CD74AC153E's extended specifications make it compatible with 74AC153PC applications.

Q: What is the difference in voltage supply specifications? A: The 74AC153PC operates from 2V to 6V, while the CD74AC153E operates from 1.5V to 5.5V. The CD74AC153E supports lower minimum voltage but has a lower maximum voltage ceiling.

Q: Are there any compliance differences between these parts? A: The CD74AC153E is RoHS non-compliant, while the 74AC153PC status is REACH Unaffected. Verify your system's compliance requirements before selection.

Q: Why are both parts marked as obsolete? A: Both the 74AC153PC and CD74AC153E are legacy 74AC logic components. Modern applications typically use newer logic families. Obsolete status indicates limited or discontinued manufacturing.

Q: Can these parts be used in new designs? A: While technically possible, using obsolete components in new designs introduces supply chain risk. Evaluate modern multiplexer alternatives for new development projects.
