74F353PC Equivalent & Substitute Parts

Part Overview

The 74F353PC is a 2 x 4:1 multiplexer logic integrated circuit manufactured by onsemi in a 16-DIP through-hole package. This component is classified as obsolete and is no longer in active production. The 74F353PC operates with a single supply voltage between 4.5V and 5.5V and is designed for applications requiring multiplexing of multiple input signals. Due to its obsolete status, identifying functionally equivalent substitute components is essential for system maintenance, repair, and redesign applications where continued availability cannot be guaranteed.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74F353PC is determined by the following critical parameters that must remain consistent:

• Circuit Configuration: 2 x 4:1 multiplexer topology
• Package Type: 16-DIP (0.300", 7.62mm) through-hole package
• Voltage Supply Range: 4.5V ~ 5.5V single supply operation
• Functional Classification: Logic multiplexer with identical pin configuration

The CD74ACT153E qualifies as a substitute based on matching all critical parameters. Both components share identical circuit topology, package form factor, and voltage supply requirements, enabling direct functional replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

Both the 74F353PC and CD74ACT153E are classified as obsolete components. Selection between these parts should be based on the following factors:

74F353PC (onsemi): Suitable for applications where the original design specification explicitly requires the 74F series logic family and where the restricted operating temperature range of 0°C to 70°C is acceptable.

CD74ACT153E (Harris Corporation): Applicable for designs requiring extended operating temperature coverage from -55°C to 125°C. The specified output current ratings of 24mA for both high and low states provide defined electrical performance characteristics. This component offers broader environmental operating conditions while maintaining identical circuit topology and package compatibility.

Both components share identical voltage supply requirements, package form factors, and circuit configurations, enabling direct substitution based on application temperature requirements and availability constraints.

Frequently Asked Questions (FAQ)

Q: Can the CD74ACT153E directly replace the 74F353PC in existing circuit boards?

A: Yes. Both components feature identical 16-DIP package dimensions (0.300", 7.62mm), through-hole mounting, and pin configurations. Direct board-level substitution is possible without PCB modifications.

Q: What are the key differences between these two multiplexer components?

A: The primary differences are operating temperature range and specified output current. The CD74ACT153E operates from -55°C to 125°C compared to the 74F353PC range of 0°C to 70°C. The CD74ACT153E specifies output current ratings of 24mA for both high and low states, while the 74F353PC does not provide this specification. Both maintain identical voltage supply requirements of 4.5V to 5.5V.

Q: Are there any compliance or regulatory differences between these parts?

A: Both components are classified as RoHS non-compliant and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. No compliance advantage exists between the two options.

Q: Which component should be selected for new designs?

A: Since both components are obsolete, neither is recommended for new designs. Current production alternatives within the multiplexer logic category should be evaluated for new applications.

Q: What is the significance of the 74F and 74ACT series designations?

A: These designations indicate different logic family implementations. The 74F series represents Fairchild Advanced Schottky logic, while 74ACT represents Advanced CMOS Technology. Both families maintain compatible voltage supply ranges and package standards, enabling functional substitution despite different internal circuit implementations.
