MAX4514CSA Equivalent & Substitute Parts

Part Overview

The MAX4514CSA is a single-circuit SPST (Single Pole Single Throw) normally-open IC switch manufactured by Analog Devices Inc./Maxim Integrated. This component operates as a 1:1 multiplexer/demultiplexer with a maximum on-state resistance of 20Ohm and is housed in an 8-SOIC surface mount package. The MAX4514CSA is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement planning.

Substitute Part Grouping Explanation

Substitution of the MAX4514CSA is determined by strict equivalence across the following critical parameters:

  • Switch Circuit Configuration: SPST - NO topology must be maintained
  • Multiplexer Ratio: 1:1 configuration required
  • On-State Resistance: Maximum 20Ohm specification
  • Supply Voltage Range: 2V ~ 12V single supply operation
  • Switching Performance: Ton ≤ 150ns, Toff ≤ 100ns
  • Charge Injection: 2pC maximum
  • Channel Capacitance: CS(off) and CD(off) at 14pF each
  • Leakage Current: IS(off) ≤ 1nA
  • Operating Temperature: 0°C ~ 70°C range
  • Package: 8-SOIC surface mount form factor

The MAX4514CSA+ is identified as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations

The MAX4514CSA+ is the direct functional equivalent of the MAX4514CSA. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The MAX4514CSA+ is preferred for new designs and ongoing procurement due to its active product status and ROHS3 compliance certification. The MAX4514CSA, classified as obsolete, should be replaced with the MAX4514CSA+ in applications where component availability and regulatory compliance are considerations. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share the same base product number (MAX4514), confirming design compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MAX4514CSA+ be used as a direct replacement for the MAX4514CSA?

A: Yes. The MAX4514CSA+ is electrically and mechanically identical to the MAX4514CSA across all specified parameters, including on-state resistance, switching times, charge injection, and package configuration. Both parts are pin-compatible 8-SOIC surface mount devices.

Q: What is the primary difference between these two parts?

A: The MAX4514CSA is classified as obsolete, while the MAX4514CSA+ maintains active product status. Additionally, the MAX4514CSA+ is ROHS3 compliant, whereas the MAX4514CSA is RoHS non-compliant. Electrical performance is identical.

Q: Are there any package or pinout differences?

A: No. Both the MAX4514CSA and MAX4514CSA+ use the 8-SOIC (0.154", 3.90mm Width) surface mount package with identical pinout and mechanical dimensions.

Q: What supply voltage range does this switch support?

A: Both parts operate with a single supply voltage range of 2V ~ 12V, making them suitable for low-voltage and standard logic applications.

Q: What is the maximum on-state resistance specification?

A: The maximum on-state resistance for both parts is 20Ohm, which determines the insertion loss and power dissipation characteristics in switching applications.

Q: What are the switching speed specifications?

A: Turn-on time (Ton) is specified at 150ns maximum, and turn-off time (Toff) is specified at 100ns maximum for both parts.
