CD74HCT4067M Equivalent & Substitute Parts

Part Overview

The CD74HCT4067M is a 16:1 multiplexer/demultiplexer interface IC manufactured by Texas Instruments in a 24-SOIC surface mount package. This single-circuit switch device operates with a supply voltage range of 4.5V to 5.5V and features an on-state resistance of 180Ohm maximum. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are necessary when addressing supply chain constraints, inventory availability, or when design specifications permit operation within the broader electrical parameter ranges of alternative manufacturers' offerings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HCT4067M is determined by the following critical parameters:

Core Functional Requirements:

• Multiplexer/Demultiplexer configuration: 16:1
• Number of circuits: 1
• Package type: 24-SOIC surface mount

Electrical Compatibility Criteria:

• On-state resistance and channel-to-channel matching must be within acceptable design tolerances
• Supply voltage range must encompass or be compatible with the application's operating voltage
• Switch timing characteristics must support the required signal bandwidth
• Operating temperature range must cover the intended application environment

Compliance & Manufacturing Standards:

• RoHS3 compliance status
• Active product status from the manufacturer
• Moisture sensitivity level appropriate for assembly and storage conditions

The substitute parts listed below meet the core 16:1 multiplexer functionality and 24-SOIC package requirement. Electrical parameter variations exist and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

CD74HCT4067M (Texas Instruments) remains the primary choice when the specified electrical parameters—particularly the 180Ohm on-state resistance, 89MHz bandwidth, and 4.5V to 5.5V supply voltage range—are required by the application. This part offers MSL 1 rating, providing maximum flexibility in manufacturing and storage environments.

MC14067BDWG (onsemi) is suitable as a substitute when the application can tolerate higher on-state resistance (280Ohm maximum) and reduced bandwidth (15MHz). The wider supply voltage range (3V to 18V) provides operational flexibility across diverse power supply configurations. The MSL 3 rating requires controlled storage conditions (168-hour maximum floor life after moisture exposure). Both the CD74HCT4067M and MC14067BDWG share identical operating temperature range (-55°C to 125°C) and 24-SOIC packaging.

HEF4067BT,653 (NXP Semiconductors) is listed as a substitute option. Complete electrical parameter specifications are not provided in the available data; therefore, compatibility assessment requires direct reference to the NXP datasheet. This part carries MSL 1 rating and active product status.

All three parts maintain RoHS3 compliance and active manufacturing status, supporting long-term supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the MC14067BDWG replace the CD74HCT4067M in all applications?

A: The MC14067BDWG is functionally equivalent as a 16:1 multiplexer in 24-SOIC packaging. However, the higher on-state resistance (280Ohm vs. 180Ohm) and reduced bandwidth (15MHz vs. 89MHz) may impact signal integrity in high-frequency or low-impedance applications. Verify that your circuit design tolerates these parameter differences before substitution.

Q: What is the significance of the MSL 3 rating on the MC14067BDWG?

A: MSL 3 indicates a maximum floor life of 168 hours after moisture exposure. This part requires controlled storage and handling procedures. In contrast, the CD74HCT4067M and HEF4067BT,653 carry MSL 1 ratings, permitting unlimited floor life. Select MSL 1 parts when manufacturing processes cannot accommodate moisture-sensitive component handling.

Q: Are all three parts pin-compatible?

A: All three parts use the 24-SOIC package. Pin compatibility must be verified against individual manufacturer datasheets, as pinout configurations may differ between manufacturers despite identical package designations.

Q: What supply voltage should I use with the MC14067BDWG?

A: The MC14067BDWG operates across 3V to 18V. If your application uses the CD74HCT4067M's 4.5V to 5.5V range, the MC14067BDWG will function within this voltage window. However, verify that the wider voltage tolerance does not introduce unintended operational characteristics in your specific circuit design.

Q: Is the HEF4067BT,653 a direct replacement for the CD74HCT4067M?

A: The HEF4067BT,653 shares the 16:1 multiplexer function and MSL 1 rating. Complete electrical parameter alignment cannot be confirmed from available data. Consult the NXP datasheet to verify compatibility with your application's bandwidth, resistance, and timing requirements before implementation.
