74HC253N,652 Equivalent & Substitute Parts

Part Overview

The 74HC253N,652 is a 2 x 4:1 multiplexer logic integrated circuit manufactured by NXP USA Inc. in a 16-DIP through-hole package. This component is classified as obsolete, indicating discontinued production and limited availability from original sources. The part operates with a single supply voltage ranging from 2V to 6V and is suitable for applications requiring signal multiplexing in digital logic circuits. Due to its obsolete status, equivalent substitute parts from active manufacturers or alternative packaging options are necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC253N,652 is determined by functional equivalence across the 74HC253 logic family. All substitute parts maintain identical multiplexer circuit configuration (2 x 4:1), output current specifications (7.8mA), and supply voltage range (2V to 6V). Substitutes are grouped by two primary differentiators: package type and product status.

Key Parameters for Substitution:

• Multiplexer circuit: 2 x 4:1 (mandatory match)
• Output current: 7.8mA high and low (mandatory match)
• Supply voltage: 2V to 6V (mandatory match)
• Package/mounting type: Determines physical compatibility
• Product status: Indicates availability and long-term support

Parameter Comparison

Engineering Selection Recommendations

SN74HC253N (Texas Instruments) is the primary substitute for new designs and production applications. This part maintains identical electrical specifications and through-hole DIP packaging, ensuring direct compatibility with existing PCB layouts. The active product status guarantees ongoing availability and manufacturer support. ROHS3 compliance aligns with current environmental and regulatory standards.

CD74HC253E (Harris Corporation) provides functional equivalence in through-hole DIP packaging with extended operating temperature range (-55°C to 125°C). This part is suitable for applications requiring wider temperature operation. However, RoHS non-compliance may restrict use in regulated industries or applications with strict environmental requirements.

CD74HC253M (Harris Corporation) offers the same electrical specifications in a 16-SOIC surface-mount package. This option is applicable only for designs utilizing surface-mount assembly processes and PCB layouts designed for SOIC footprints. The extended temperature range (-55°C to 125°C) supports demanding thermal environments.

Frequently Asked Questions (FAQ)

Q: Can SN74HC253N directly replace 74HC253N,652 in existing designs? A: Yes. Both parts share identical multiplexer configuration (2 x 4:1), output current (7.8mA), supply voltage range (2V to 6V), and 16-DIP through-hole packaging. The SN74HC253N is pin-compatible and functionally equivalent.

Q: What is the difference between CD74HC253E and CD74HC253M? A: The primary difference is package type. CD74HC253E uses 16-PDIP through-hole packaging, while CD74HC253M uses 16-SOIC surface-mount packaging. Both maintain identical electrical specifications and extended operating temperature range (-55°C to 125°C).

Q: Does RoHS compliance affect substitution decisions? A: RoHS compliance is a regulatory and environmental consideration. SN74HC253N (ROHS3 compliant) is preferred for applications subject to environmental regulations. CD74HC253E and CD74HC253M (RoHS non-compliant) may be restricted in certain industries or geographic markets.

Q: Are there temperature range differences between substitutes? A: Yes. SN74HC253N operates from -40°C to 85°C, while CD74HC253E and CD74HC253M operate from -55°C to 125°C. Select based on application thermal requirements.

Q: Can CD74HC253M be used in through-hole PCB designs? A: No. CD74HC253M is a surface-mount component in 16-SOIC packaging. It requires PCB layouts and assembly processes designed for surface-mount technology. For through-hole designs, use SN74HC253N or CD74HC253E.
