CD74HC4016E Equivalent & Substitute Parts

Part Overview

The CD74HC4016E is a 4-circuit SPST-NO (Single Pole Single Throw - Normally Open) analog switch manufactured by Texas Instruments, housed in a 14-DIP through-hole package. This component functions as a general-purpose electronic switch for signal routing and multiplexing applications across a 2V to 10V single supply voltage range. The CD74HC4016E is classified as Last Time Buy, indicating end-of-life status. Identifying equivalent and substitute parts is essential for ongoing design support, production continuity, and long-term system reliability when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution of the CD74HC4016E is determined by the following critical parameters:

Functional Equivalence: Switch circuit type (SPST-NO), number of circuits (4), and multiplexer configuration (1:1) must remain identical
Electrical Compatibility: Supply voltage range (2V ~ 10V) and operating temperature range (-55°C ~ 125°C) must be maintained or exceeded
Regulatory Compliance: RoHS3 compliance and REACH unaffected status must be preserved
Package Consideration: Substitutes may differ in mounting type (through-hole versus surface mount) and physical package dimensions, provided the functional pin configuration remains compatible with the application's integration method

The CD74HC4066M96 qualifies as a manufacturer-recommended substitute based on identical functional specifications, equivalent electrical performance within acceptable parameters, and maintained regulatory compliance.

Engineering Selection Recommendations

The CD74HC4066M96 is the manufacturer-recommended substitute for the CD74HC4016E. Both devices maintain identical functional specifications (4-circuit SPST-NO configuration, 1:1 multiplexer topology, 2V to 10V supply range, and -55°C to 125°C operating temperature). Both achieve ROHS3 compliance and REACH unaffected status.

The primary distinction is packaging: the CD74HC4016E uses through-hole 14-DIP mounting, while the CD74HC4066M96 employs surface-mount 14-SOIC technology. This difference requires PCB redesign if direct pin-for-pin substitution on existing through-hole layouts is required. However, the CD74HC4066M96 offers superior electrical performance, including lower on-state resistance (70Ohm versus 170Ohm), tighter channel-to-channel matching (500mOhm versus 8.5Ohm), higher bandwidth (200MHz versus 20MHz), and lower channel capacitance (5pF versus 10pF).

The CD74HC4066M96 is in active production status, ensuring long-term availability and supply chain stability, whereas the CD74HC4016E is Last Time Buy.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4066M96 directly replace the CD74HC4016E on existing PCBs?

A: Direct PCB replacement is not possible without redesign. The CD74HC4016E uses through-hole 14-DIP packaging, while the CD74HC4066M96 uses surface-mount 14-SOIC packaging. PCB layout and footprint modifications are required. However, the pin functional configuration is identical, allowing schematic-level substitution with appropriate PCB redesign.

Q: Are the electrical specifications compatible between these two parts?

A: Yes. Both devices operate across the identical 2V to 10V supply voltage range and -55°C to 125°C temperature range. The CD74HC4066M96 provides improved electrical performance with lower on-state resistance and higher bandwidth, making it suitable for applications requiring enhanced signal integrity.

Q: What is the significance of the Last Time Buy status for the CD74HC4016E?

A: Last Time Buy indicates that the CD74HC4016E has reached end-of-life. Texas Instruments will discontinue production after existing inventory is exhausted. New designs should transition to the CD74HC4066M96 or equivalent active-status alternatives to ensure long-term component availability and supply chain continuity.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the CD74HC4016E and CD74HC4066M96 are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: What are the key performance differences between these parts?

A: The CD74HC4066M96 offers superior performance: on-state resistance is reduced from 170Ohm to 70Ohm, channel-to-channel matching improves from 8.5Ohm to 500mOhm, bandwidth increases from 20MHz to 200MHz, and channel capacitance decreases from 10pF to 5pF. These improvements benefit high-speed signal routing and low-distortion applications.

Q: Which part should be selected for new designs?

A: The CD74HC4066M96 should be selected for new designs. It is in active production, offers superior electrical performance, and provides long-term design support and availability.
