DG542AP Equivalent & Substitute Parts

Part Overview

The DG542AP is a quad SPST video switch IC manufactured by Vishay Siliconix in a 16-DIP package. This component functions as a 4-channel video multiplexer/demultiplexer with 1:1 circuit configuration, designed for video signal routing applications. The DG542AP is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DG542AP is determined by the following critical parameters:

• Switch Configuration: SPST (Single Pole Single Throw) topology with 4 independent channels
• Package Compatibility: 16-DIP (0.300", 7.62mm) through-hole form factor
• Electrical Performance: On-state resistance, supply voltage range, and bandwidth specifications
• Supply Voltage Support: Dual supply (V±) capability for ±3V to ±15V operation
• Channel Count: Exactly 4 channels for direct functional replacement

The IH5352CPE+ qualifies as a manufacturer-recommended substitute based on matching package type, channel configuration, and SPST switch circuit topology. Both components maintain the same physical footprint and pinout compatibility required for direct board-level substitution.

Parameter Comparison

Engineering Selection Recommendations

The IH5352CPE+ is an active, in-production component suitable for replacing the obsolete DG542AP in new designs. Key considerations for selection:

Compliance: The IH5352CPE+ meets ROHS3 compliance requirements, whereas the DG542AP is non-compliant. For applications subject to RoHS regulations, the IH5352CPE+ is the required choice.

Product Lifecycle: The DG542AP is obsolete with no ongoing manufacturing. The IH5352CPE+ is actively produced, ensuring long-term availability and supply chain stability.

Electrical Differences: The IH5352CPE+ exhibits a maximum on-state resistance of 75Ω compared to 60Ω for the DG542AP. The dual supply voltage range begins at ±5V rather than ±3V. Operating temperature range is narrower (0°C ~ 70°C versus -55°C ~ 125°C). These differences must be evaluated against specific application requirements.

Package Compatibility: Both components use identical 16-DIP (0.300", 7.62mm) through-hole packaging, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the IH5352CPE+ directly replace the DG542AP without circuit modifications?

A: Both components share the same 16-DIP package and pinout. However, verify that your application tolerates the IH5352CPE+ specifications: maximum 75Ω on-state resistance, ±5V minimum dual supply voltage, and 0°C ~ 70°C operating temperature range.

Q: What is the primary reason for substituting the DG542AP?

A: The DG542AP is obsolete and no longer manufactured. The IH5352CPE+ is the manufacturer-recommended active substitute for continued production and new designs.

Q: Are there packaging alternatives to the 16-DIP form factor?

A: The provided substitute part list includes only the IH5352CPE+, which maintains the 16-DIP package. No alternative package options are specified in this reference.

Q: Does the IH5352CPE+ meet modern compliance standards?

A: Yes, the IH5352CPE+ is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The DG542AP is RoHS non-compliant.

Q: What is the significance of the on-state resistance difference?

A: The DG542AP specifies 60Ω maximum on-state resistance, while the IH5352CPE+ specifies 75Ω. This 15Ω difference affects signal attenuation and power dissipation in video switching applications. Verify compatibility with your circuit design specifications.

Q: Are the supply voltage ranges compatible?

A: The DG542AP supports ±3V ~ 15V dual supply, while the IH5352CPE+ requires ±5V ~ 15V. Applications operating below ±5V cannot use the IH5352CPE+ as a substitute.
