CD74HC193M96 Equivalent & Substitute Parts

Part Overview

The CD74HC193M96 is a 4-bit binary counter IC manufactured by Texas Instruments in a 16-SOIC surface mount package. This logic component functions as a synchronous up/down counter with asynchronous reset capability, operating across a supply voltage range of 2V to 6V and a temperature range of -55°C to 125°C. The part is currently in active production status with 790 units available in inventory.

Substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design requirements permit functional equivalents from alternative manufacturers. The CD74HC193M96 has entered a transition phase where equivalent alternatives from other manufacturers provide identical or enhanced electrical performance while maintaining full functional compatibility.

Engineering Selection Recommendations

Primary Recommendation: 74HC193D,653 (NXP USA Inc.)

The 74HC193D,653 is the preferred substitute for new designs and ongoing production. This part maintains active product status with the highest inventory availability (9784 units), ensuring supply continuity. It meets all electrical and mechanical compatibility requirements with identical pin configuration and functional behavior. The part carries ROHS3 compliance and EAR99 export classification matching the original specification.

Secondary Recommendation: CD74HC193MT (Texas Instruments)

The CD74HC193MT provides continuity within the Texas Instruments product line with identical electrical specifications to the CD74HC193M96. This part is currently in Last Time Buy status, making it suitable for designs requiring extended production runs before transition to alternative sources. Inventory availability is substantial at 1764 units.

Alternative Option: 74HC193D,652 (Nexperia USA Inc.)

The 74HC193D,652 offers enhanced count rate performance at 49 MHz compared to the 29 MHz specification of the primary part. However, this part carries Obsolete product status, limiting its suitability for new production programs. The operating temperature range is restricted to -40°C to 125°C, which excludes the lower temperature extreme of -55°C specified for the original part.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC193MT be used as a direct replacement for the CD74HC193M96?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, pin configuration, and 16-SOIC package dimensions. The CD74HC193MT is a parametric equivalent suitable for direct substitution in existing designs.

Q: What is the difference between the Nexperia and NXP part numbers?

A: The 74HC193D,652 (Nexperia USA Inc.) and 74HC193D,653 (NXP USA Inc.) are variants of the same base product (74HC193) with different packaging and product status designations. The 74HC193D,653 is in active production status, while the 74HC193D,652 is obsolete.

Q: Are there any temperature range limitations when substituting with Nexperia or NXP parts?

A: The Nexperia 74HC193D,652 and NXP 74HC193D,653 both specify an operating temperature range of -40°C to 125°C. If your application requires operation at -55°C, the Texas Instruments CD74HC193M96 or CD74HC193MT must be used.

Q: Do all substitute parts have the same count rate?

A: No. The CD74HC193M96 and CD74HC193MT specify 29 MHz count rate. The Nexperia 74HC193D,652 and NXP 74HC193D,653 specify 49 MHz. Both rates are compatible with designs specified for 29 MHz operation.

Q: What packaging differences exist between these parts?

A: All parts use the 16-SOIC (0.154", 3.90mm Width) surface mount package with identical pin configuration and PCB footprint. No layout modifications are required when substituting between these parts.

Q: Which part should be selected for new production designs?

A: The 74HC193D,653 (NXP USA Inc.) is recommended for new production due to active product status and highest inventory availability. This ensures long-term supply security and design continuity.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting environmental and regulatory requirements equivalent to the original CD74HC193M96.
