MAX4547ESE Video Switch IC - Equivalent & Substitute Parts

Part Overview

The MAX4547ESE is a bidirectional RF video switch IC manufactured by Analog Devices Inc./Maxim Integrated. This 2-channel SPDT (Single Pole Double Throw) video switch is designed for video signal routing applications requiring low on-state resistance and high bandwidth performance. The device operates across a wide supply voltage range and features break-before-make switching configuration.

The MAX4547ESE is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, production continuity, and long-term system support where original inventory becomes depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4547ESE is determined by strict equivalence across the following critical parameters:

• Switch Architecture: SPDT configuration with 2 channels
• Electrical Performance: On-state resistance maximum of 20Ω, -3dB bandwidth of 300MHz
• Supply Voltage Compatibility: Single supply 2.7V ~ 12V and dual supply ±2.7V ~ 6V
• Operating Temperature Range: -40°C ~ 85°C
• Package Specification: 16-SOIC form factor with identical pin configuration
• Functional Features: Bi-directional switching with break-before-make operation

The MAX4547ESE+ qualifies as a direct substitute based on complete electrical and mechanical parameter equivalence. The primary distinction is product status and compliance certification, not functional or performance characteristics.

Engineering Selection Recommendations

The MAX4547ESE+ is the direct functional equivalent of the MAX4547ESE. Selection between these parts should be based on the following criteria:

Product Status: The MAX4547ESE is obsolete, while the MAX4547ESE+ maintains active product status with ongoing manufacturer support and availability.

Compliance Requirements: The MAX4547ESE+ is ROHS3 compliant, whereas the MAX4547ESE is RoHS non-compliant. Applications subject to RoHS directives or customer specifications requiring RoHS compliance must use the MAX4547ESE+.

Supply Chain Continuity: The MAX4547ESE+ is available in tube packaging with documented inventory. The MAX4547ESE, though currently in stock (3300 pcs), represents a declining resource as an obsolete part.

Electrical and Mechanical Equivalence: Both parts are electrically and mechanically identical. Pin configuration, signal integrity, and performance characteristics are equivalent across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can MAX4547ESE+ be used as a direct replacement for MAX4547ESE in existing designs?

A: Yes. The MAX4547ESE+ is electrically and mechanically equivalent. No circuit modifications or PCB redesign is required. Both parts share identical pin configuration, electrical specifications, and functional characteristics.

Q: What is the difference between MAX4547ESE and MAX4547ESE+?

A: The primary differences are product status and compliance certification. The MAX4547ESE is obsolete and RoHS non-compliant. The MAX4547ESE+ is an active product with ROHS3 compliance. Electrical performance and package specifications are identical.

Q: Are there any package compatibility issues when substituting MAX4547ESE with MAX4547ESE+?

A: No. Both parts use the 16-SOIC package with identical dimensions (0.154", 3.90mm width). PCB footprints and assembly processes remain unchanged.

Q: Which part should be selected for new designs?

A: The MAX4547ESE+ should be selected for new designs. It offers active product status, RoHS compliance, and assured long-term availability.

Q: Is the -3dB bandwidth specification identical between both parts?

A: Yes. Both MAX4547ESE and MAX4547ESE+ specify 300MHz -3dB bandwidth. Signal integrity and frequency response characteristics are equivalent.

Q: What supply voltage options are supported by both parts?

A: Both parts support single supply operation (2.7V ~ 12V) and dual supply operation (±2.7V ~ 6V). Circuit design flexibility remains unchanged between the two parts.
