CD74HCT4052ME4 Equivalent & Substitute Parts

Part Overview

The CD74HCT4052ME4 is a dual 4:1 analog multiplexer/demultiplexer switch IC manufactured by Texas Instruments, housed in a 16-SOIC surface mount package. This component functions as a precision switch for analog signal routing applications, featuring SP4T (Single Pole, 4-Throw) switching architecture with 130Ohm on-state resistance.

The CD74HCT4052ME4 has been discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HCT4052ME4 is determined by the following critical parameters:

Switch Architecture: SP4T configuration with 4:1 multiplexer/demultiplexer functionality
Circuit Count: Dual circuit (2 circuits) requirement
On-State Resistance: Maximum 130Ohm specification
Supply Voltage Compatibility: 4.5V ~ 5.5V single supply or ±1V ~ 5V dual supply operation
Package Type: 16-SOIC surface mount form factor
Bandwidth Performance: Minimum 180MHz -3dB bandwidth
Leakage Current: Maximum 200nA specification
Temperature Range: Operating range of -55°C to 125°C

Substitute parts must maintain functional equivalence across these parameters. Variations in on-state resistance, leakage current, or bandwidth within acceptable engineering tolerances do not preclude substitution if the core switching architecture and package remain identical.

Engineering Selection Recommendations

CD74HCT4052M (Texas Instruments)

This part maintains identical electrical specifications to the CD74HCT4052ME4, including on-state resistance, bandwidth, and leakage current. The primary difference is packaging format (Tube versus bulk). Current inventory status is Last Time Buy, indicating limited future availability. This substitute is recommended for applications requiring exact parameter matching and continued Texas Instruments supply chain support.

74HCT4052D,118 (Nexperia USA Inc.)

This part provides functional substitution with measurable parameter variations: on-state resistance increases to 150Ohm (20Ohm higher), leakage current increases to 2µA (10x higher), and operating temperature range is reduced to -40°C ~ 125°C (5°C reduction at lower bound). Bandwidth remains acceptable at 180MHz. Product status is Active, ensuring long-term availability. This substitute is suitable for applications where the parameter variations fall within design tolerances and extended temperature operation below -40°C is not required.

Both substitutes maintain ROHS3 compliance, MSL Level 1 rating, and 16-SOIC package compatibility. Selection should be based on specific application requirements regarding on-state resistance, leakage current, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 74HCT4052D,118 replace the CD74HCT4052ME4 in all applications?

A: The 74HCT4052D,118 is functionally compatible for most applications but exhibits higher on-state resistance (150Ohm vs. 130Ohm) and higher leakage current (2µA vs. 200nA). Applications sensitive to signal attenuation or requiring ultra-low leakage performance should evaluate these parameter differences against design specifications. The reduced operating temperature range (-40°C minimum vs. -55°C minimum) may also be a limiting factor for extreme cold environment applications.

Q: What is the difference between CD74HCT4052M and CD74HCT4052ME4?

A: Both parts are manufactured by Texas Instruments with identical electrical specifications. The primary difference is packaging: CD74HCT4052ME4 is supplied in bulk packaging, while CD74HCT4052M is supplied in Tube packaging. Electrical performance, pin configuration, and functional behavior are equivalent.

Q: Are all three parts pin-compatible?

A: Yes. All three parts (CD74HCT4052ME4, CD74HCT4052M, and 74HCT4052D,118) use the 16-SOIC package with identical pin assignments. Direct PCB substitution is possible without layout modifications.

Q: Which substitute offers the best long-term availability?

A: The 74HCT4052D,118 from Nexperia USA Inc. carries Active product status, indicating ongoing manufacturing and supply chain support. The CD74HCT4052M is designated Last Time Buy, indicating limited future availability. For new designs requiring extended production support, the Nexperia part is recommended.

Q: Do all parts meet RoHS and REACH compliance requirements?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.
