Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC563N,652 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 1:8 or 8:8 (functionally equivalent for this application)
• Output Type: Tri-State
• Voltage Supply Range: 2V ~ 6V (minimum overlap required)
• Package / Case: 20-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Base Product Number: 74HC563

Electrical Performance Parameters:

• Propagation Delay Time
• Output Current Ratings (High/Low)
• Operating Temperature Range

The substitute parts CD74HC563E and SN74HC563N meet all mandatory compatibility criteria and share the same base product number (74HC563), confirming functional equivalence within the 74HC logic family. Both alternatives are manufactured by Texas Instruments and maintain active product status, providing long-term availability advantages over the obsolete NXP part.

Parameter Comparison

Engineering Selection Recommendations

CD74HC563E (Texas Instruments)

This substitute offers the fastest propagation delay at 12ns and the widest operating temperature range (-55°C to 125°C), providing superior performance margins for timing-critical applications and extended environmental operation. Active product status ensures sustained availability and manufacturing support. ROHS3 compliance and REACH unaffected status confirm regulatory alignment.

SN74HC563N (Texas Instruments)

This alternative maintains full electrical compatibility with output current specifications and supply voltage range identical to the original part. Active product status guarantees long-term procurement viability. Operating temperature range of -40°C to 85°C covers standard industrial applications. ROHS3 compliance and REACH unaffected status satisfy regulatory requirements. Propagation delay of 23ns remains within acceptable parameters for non-time-critical logic circuits.

Both Texas Instruments substitutes eliminate obsolescence risk associated with the NXP part while maintaining functional equivalence, package compatibility, and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can CD74HC563E and SN74HC563N be used interchangeably with 74HC563N,652?

A: Both Texas Instruments parts are functionally equivalent substitutes. They share identical logic type, tri-state output configuration, supply voltage range, and 20-DIP package specifications. Selection between them depends on application timing requirements and operating temperature constraints.

Q: What is the difference between the 1:8 and 8:8 circuit configurations?

A: The circuit designation refers to the latch configuration. Both configurations provide functionally equivalent D-Type transparent latch operation within the 74HC563 family. The 8:8 designation in the substitute parts indicates full 8-bit latch capability, maintaining compatibility with the original 1:8 configuration.

Q: Are there temperature range considerations when selecting a substitute?

A: The CD74HC563E operates from -55°C to 125°C, providing the widest temperature margin. The SN74HC563N operates from -40°C to 85°C. The original 74HC563N,652 operates from -40°C to 125°C. Application requirements determine which temperature range is appropriate.

Q: How do propagation delay differences affect circuit performance?

A: CD74HC563E provides 12ns delay, the original part 14ns, and SN74HC563N 23ns. For timing-critical applications, CD74HC563E offers the fastest response. For standard logic circuits, all three parts meet typical propagation delay requirements.

Q: Are both substitutes RoHS and REACH compliant?

A: Yes. Both CD74HC563E and SN74HC563N are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original 74HC563N,652.

Q: What is the packaging difference between the main part and substitutes?

A: All three parts use identical 20-DIP (0.300", 7.62mm) through-hole packages. Physical footprint and pin configuration are identical, enabling direct board-level substitution without layout modifications.
