Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ACTQ153PC is determined by the following critical parameters:

• Circuit Configuration: Must be 2 x 4:1 multiplexer topology
• Package Type: Must be 16-DIP (0.300", 7.62mm) for mechanical and electrical compatibility
• Mounting Method: Must be through-hole compatible
• Voltage Supply Range: Must support 4.5V ~ 5.5V single supply operation
• Output Current Capability: Must provide minimum 24mA output current (high and low)
• Functional Equivalence: Must perform identical multiplexer selection and data routing functions

The CD74ACT153E from Harris Corporation meets all substitution criteria, maintaining identical circuit configuration, package dimensions, and electrical performance specifications within the defined operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The CD74ACT153E serves as a direct functional equivalent to the 74ACTQ153PC. Both components are classified as obsolete products, requiring substitution for new procurement activities.

The CD74ACT153E provides an extended operating temperature range (-55°C ~ 125°C) compared to the 74ACTQ153PC (-40°C ~ 85°C), making it suitable for applications requiring broader thermal performance. All critical electrical parameters—voltage supply, output current, and circuit configuration—are identical between the two parts.

The CD74ACT153E is supplied in tube packaging, whereas the 74ACTQ153PC information does not specify packaging format. This difference affects handling and storage procedures but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CD74ACT153E directly replace the 74ACTQ153PC in existing designs?

A: Yes. The CD74ACT153E is electrically and mechanically equivalent. Both components feature identical 2 x 4:1 multiplexer configuration, 16-DIP package dimensions, voltage supply range (4.5V ~ 5.5V), and output current specifications (24mA). Pin-for-pin compatibility is maintained.

Q: What is the significance of the extended temperature range in the CD74ACT153E?

A: The CD74ACT153E operates from -55°C ~ 125°C, exceeding the 74ACTQ153PC range of -40°C ~ 85°C. This extended range provides design flexibility for applications requiring operation in wider thermal environments. If your application operates within the original -40°C ~ 85°C specification, both parts perform identically.

Q: Are there differences in packaging that affect circuit board assembly?

A: Both parts use 16-DIP through-hole packages with identical 0.300" (7.62mm) body width. The CD74ACT153E is supplied in tube packaging format. This affects component handling and tape-and-reel availability but does not impact PCB footprint or soldering procedures.

Q: Why are both parts classified as obsolete?

A: Both the 74ACTQ153PC and CD74ACT153E are obsolete products. Modern designs typically utilize surface-mount logic devices or programmable logic solutions. These through-hole DIP packages represent legacy technology. Substitution is necessary for maintenance, repair, or continuation of existing designs using these components.

Q: What compliance certifications apply to these parts?

A: Both components carry EAR99 export classification and HTSUS code 8542.39.0001. The CD74ACT153E is marked as RoHS non-compliant. Compliance requirements should be verified against your specific application and regional regulations.
