CD74HCT86EE4 Equivalent & Substitute Parts

Part Overview

The CD74HCT86EE4 is a 4-channel XOR (Exclusive OR) logic gate integrated circuit manufactured by Texas Instruments in a 14-pin DIP package. This component performs exclusive OR logic operations across four independent channels, each with two inputs. The device operates within the 4.5V to 5.5V supply voltage range and is designed for through-hole mounting applications.

The CD74HCT86EE4 maintains Active product status with full RoHS3 compliance and REACH unaffected certification. Identifying equivalent and substitute parts is necessary when the primary source becomes unavailable, when alternative manufacturers are required for supply chain diversification, or when specific compliance requirements necessitate component alternatives.

Substitution of the CD74HCT86EE4 is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Logic Type: XOR (Exclusive OR)
• Number of Circuits: 4 channels
• Number of Inputs: 2 inputs per channel

Electrical Parameters:

• Voltage - Supply: 4.5V ~ 5.5V
• Current - Quiescent (Max): 2 µA
• Current - Output High, Low: 4mA, 4mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Max Propagation Delay @ 4.5V, 50pF: 32ns
• Operating Temperature: -55°C ~ 125°C

Physical Parameters:

• Mounting Type: Through Hole
• Package / Case: 14-DIP (0.300", 7.62mm)
• Series: 74HCT

All substitute parts must match these parameters exactly to ensure functional and mechanical compatibility within the target application.

Engineering Selection Recommendations

CD74HCT86EE4 (Primary Selection)

The CD74HCT86EE4 from Texas Instruments is the recommended primary selection. This component maintains Active product status, ensuring continued availability and manufacturer support. Full RoHS3 compliance and REACH unaffected certification satisfy modern environmental and regulatory requirements for new designs and production environments with strict compliance mandates.

CD74HCT86E (Alternative Selection)

The CD74HCT86E from Harris Corporation provides parametric equivalence across all electrical and mechanical specifications. However, this part carries Obsolete product status, indicating discontinued manufacturing and limited availability. Additionally, RoHS non-compliance restricts its use in applications subject to RoHS regulations. This substitute is suitable only for legacy system maintenance, repair operations, or applications where RoHS compliance is not required.

Selection between these parts depends on application context: new designs and regulated environments require the CD74HCT86EE4; legacy system support may utilize the CD74HCT86E where compliance restrictions do not apply.

Frequently Asked Questions (FAQ)

Q: Can the CD74HCT86E replace the CD74HCT86EE4 in new production designs?

A: The CD74HCT86E matches all electrical and mechanical parameters required for functional substitution. However, its Obsolete status and RoHS non-compliance make it unsuitable for new production designs subject to modern regulatory requirements. The CD74HCT86EE4 is the appropriate choice for new designs.

Q: Are there any pin configuration differences between these parts?

A: Both parts use identical 14-DIP (0.300", 7.62mm) packaging with through-hole mounting. Pin configuration and spacing are equivalent, allowing direct socket substitution where electrical compliance permits.

Q: What is the significance of the RoHS compliance difference?

A: RoHS3 compliance (CD74HCT86EE4) restricts hazardous substances in electrical and electronic equipment. RoHS non-compliance (CD74HCT86E) indicates the part may contain restricted materials. Applications subject to RoHS regulations, including EU markets and regulated industries, require the compliant CD74HCT86EE4.

Q: Do both parts operate at identical voltage and temperature ranges?

A: Yes. Both the CD74HCT86EE4 and CD74HCT86E operate within 4.5V to 5.5V supply voltage and -55°C to 125°C temperature ranges. Electrical performance characteristics, including propagation delay, quiescent current, and output drive capability, are identical.

Q: Why is the CD74HCT86E listed as Obsolete?

A: Obsolete status indicates Harris Corporation has discontinued manufacturing this part. Existing inventory may be available through secondary distributors, but long-term availability cannot be assured. The Active status of the CD74HCT86EE4 ensures continued supply from Texas Instruments.
