Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC4514EN is determined by matching the following critical electrical and mechanical parameters:

• Functional Circuit: 1 x 4:16 decoder/demultiplexer configuration
• Output Current Specifications: 5.2mA high and low output current capability
• Supply Voltage Range: 2V ~ 6V single supply operation
• Operating Temperature Range: -55°C ~ 125°C
• Base Product Number: 74HC4514 series compatibility
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The CD74HC4514M96 qualifies as a direct functional substitute, maintaining identical electrical specifications while differing only in mounting technology (surface mount versus through hole) and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The CD74HC4514M96 is the primary substitute for the obsolete CD74HC4514EN. Both devices maintain identical electrical performance specifications and comply with ROHS3 and REACH requirements. The CD74HC4514M96 carries active product status, ensuring continued availability and manufacturing support from Texas Instruments.

Selection between these parts depends on board-level design constraints. The CD74HC4514EN uses through-hole mounting (24-DIP package), while the CD74HC4514M96 uses surface-mount technology (24-SOIC package). PCB layout, assembly process capability, and existing design infrastructure determine which package format is appropriate for a given application.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4514M96 directly replace the CD74HC4514EN in existing designs?

A: Electrical substitution is complete. The CD74HC4514M96 maintains all functional specifications, supply voltage range, output current ratings, and operating temperature range. Package and mounting type differ, requiring PCB redesign and assembly process adjustment.

Q: What are the key differences between these parts?

A: The primary differences are mounting technology and package format. The CD74HC4514EN is a through-hole 24-DIP device, while the CD74HC4514M96 is a surface-mount 24-SOIC device. Electrical performance is identical.

Q: Why is the CD74HC4514EN classified as obsolete?

A: The CD74HC4514EN has reached end-of-life status with Texas Instruments. The CD74HC4514M96 represents the active product continuation in the 74HC4514 family.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both devices.

Q: What supply voltage range do these devices support?

A: Both the CD74HC4514EN and CD74HC4514M96 operate with a single supply voltage range of 2V to 6V.

Q: Are the output current specifications identical?

A: Yes. Both devices provide 5.2mA output current capability for both high and low states.
