74HC4094N,652 Equivalent & Substitute Parts

Part Overview

The 74HC4094N,652 is an 8-stage shift register with serial-to-parallel and serial output functions, manufactured by NXP Semiconductors in a 16-DIP through-hole package. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing production and maintenance applications. The shift register operates across a 2V to 6V supply voltage range and supports tri-state output configuration, making it suitable for bus-oriented digital logic applications requiring serial data conversion.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC4094N,652 is determined by the following critical parameters:

• Base product number (74HC4094) ensures functional equivalence
• Logic type (Shift Register) and bit configuration (1 Element, 8 Bit)
• Output type (Tri-State) and function (Serial to Parallel, Serial)
• Supply voltage range (2V ~ 6V) and operating temperature compatibility
• RoHS3 compliance and REACH unaffected status for regulatory alignment

Two substitute parts meet these criteria with variations in mounting technology and product status. The CD74HC4094E represents an active upgrade option with extended temperature range, while the 74HC4094D,653 offers an active surface-mount alternative with identical electrical specifications to the original part.

Parameter Comparison

Engineering Selection Recommendations

The 74HC4094N,652 is obsolete and requires substitution for new designs and ongoing procurement. Both substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

The CD74HC4094E (Texas Instruments) is suitable for applications requiring extended low-temperature operation (-55°C minimum versus -40°C). This part retains the through-hole 16-DIP package, enabling direct socket replacement without PCB redesign. The extended temperature range provides additional operational margin for demanding environments.

The 74HC4094D,653 (Nexperia USA Inc.) is the manufacturer-recommended substitute, offering identical electrical specifications and operating temperature range to the original part. This part transitions to surface-mount 16-SOIC packaging, requiring PCB layout modification but providing reduced board footprint and improved thermal characteristics. This option is preferred for new PCB designs and high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4094E directly replace the 74HC4094N,652 in existing through-hole designs?

A: Yes. The CD74HC4094E maintains the 16-DIP through-hole package and identical pin configuration. The extended operating temperature range (-55°C to 125°C) provides additional environmental margin without affecting electrical compatibility.

Q: What is the primary difference between the CD74HC4094E and 74HC4094D,653?

A: The CD74HC4094E uses through-hole 16-DIP packaging, while the 74HC4094D,653 uses surface-mount 16-SOIC packaging. Both are electrically equivalent with identical supply voltage (2V ~ 6V) and tri-state output characteristics. Package selection depends on PCB assembly technology and design constraints.

Q: Is the 74HC4094D,653 compatible with existing through-hole PCB layouts?

A: No. The 74HC4094D,653 requires surface-mount assembly and cannot be used in through-hole sockets. PCB redesign is necessary for this substitution. For through-hole compatibility, use the CD74HC4094E.

Q: Do all substitute parts meet the same compliance standards as the original?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment for industrial and commercial applications.

Q: What is the functional difference between the "Serial to Parallel, Serial" and "Serial to Parallel" function specifications?

A: The original 74HC4094N,652 and 74HC4094D,653 support both serial-to-parallel conversion and serial output modes. The CD74HC4094E specifies serial-to-parallel function. Verify application requirements for serial output functionality before selecting the CD74HC4094E.
