MAX4546ESE Video Switch IC - Equivalent & Substitute Parts

Part Overview

The MAX4546ESE is a bidirectional RF video switch IC manufactured by Analog Devices Inc./Maxim Integrated. This 2-channel SPST (Single Pole Single Throw) video switch operates across a wide supply voltage range and delivers 300MHz bandwidth performance suitable for video multiplexing and demultiplexing applications. The main part number MAX4546ESE is currently classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4546ESE is determined by strict equivalence across the following critical parameters:

• Package / Case: 16-SOIC (0.154", 3.90mm Width) — ensures mechanical and thermal compatibility with existing PCB layouts
• Number of Channels: 2 — maintains functional channel count
• Switch Circuit: SPST — preserves switching topology
• On-State Resistance (Max): 20Ω — ensures signal integrity and impedance matching
• Voltage - Supply, Single (V+): 2.7V ~ 12V — confirms power supply compatibility
• Voltage - Supply, Dual (V±): ±2.7V ~ 6V — confirms dual supply compatibility
• -3dB Bandwidth: 300MHz — maintains RF/video signal fidelity
• Operating Temperature: -40°C ~ 85°C (TA) — ensures thermal operating range compatibility
• Features: Bi-Directional, Break-Before-Make, T-Switch Configuration — preserves functional behavior

The substitute part MAX4546ESE+ meets all these criteria and is therefore electrically and mechanically equivalent to the main part number.

Parameter Comparison

Engineering Selection Recommendations

The MAX4546ESE+ is the direct substitute for MAX4546ESE based on complete electrical and mechanical parameter equivalence. The primary distinction between these part numbers is product lifecycle status and regulatory compliance:

• MAX4546ESE is classified as obsolete and carries RoHS non-compliant status
• MAX4546ESE+ is classified as active and carries ROHS3 compliant status

For new designs and ongoing system support, MAX4546ESE+ is the appropriate selection. Both parts are REACH Unaffected and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The active product status of MAX4546ESE+ ensures continued availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can MAX4546ESE+ be used as a direct replacement for MAX4546ESE in existing designs?

A: Yes. MAX4546ESE+ is electrically and mechanically equivalent across all critical parameters including package, channel count, switching topology, impedance, supply voltage ranges, bandwidth, and operating temperature. No circuit modifications are required.

Q: What is the difference between MAX4546ESE and MAX4546ESE+?

A: The primary differences are product status and regulatory compliance. MAX4546ESE is obsolete and RoHS non-compliant, while MAX4546ESE+ is active and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these part numbers?

A: Both parts use the 16-SOIC package. MAX4546ESE+ is supplied in Tube packaging, while MAX4546ESE packaging is not specified in the available data.

Q: What supply voltage configurations does this video switch support?

A: The MAX4546ESE and MAX4546ESE+ support both single supply (2.7V ~ 12V) and dual supply (±2.7V ~ 6V) configurations, providing flexibility for various system architectures.

Q: Is the 300MHz bandwidth suitable for standard video applications?

A: Yes. The 300MHz -3dB bandwidth is suitable for RF and video multiplexing/demultiplexing applications within the specified operating parameters.

Q: What is the significance of the break-before-make feature?

A: Break-before-make ensures that the switch disconnects the previous signal path before connecting the new signal path, preventing signal glitches and cross-talk during switching transitions.
