Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI5V330WEX is determined by the following critical parameters:

• Package Compatibility: 16-SOIC form factor (0.154", 3.90mm Width) - mechanical and electrical interface requirement
• Circuit Configuration: 2:1 multiplexer/demultiplexer with 4 channels - functional topology
• On-State Resistance: Maximum 10Ohm - signal integrity and power dissipation specification
• Supply Voltage: 5V single supply operation - power delivery compatibility
• Bandwidth: Minimum 400MHz -3dB bandwidth - video signal fidelity requirement
• Features: Bi-directional, RGB-capable switching - application-specific functionality
• Operating Temperature Range: -40°C to 85°C minimum - thermal operating envelope
• RoHS3 Compliance: Environmental and regulatory requirement

Two substitute parts meet these criteria with varying performance characteristics and availability status.

Parameter Comparison

Engineering Selection Recommendations

TS5V330DR (Texas Instruments) provides the closest functional match to the PI5V330WEX. Both parts share identical on-state resistance (10Ohm maximum), matching channel count, 2:1 circuit configuration, and RGB bi-directional capability. The TS5V330DR operates within a wider supply voltage range (4V to 5.5V) compared to the fixed 5V specification of the PI5V330WEX, offering improved design flexibility. However, the -3dB bandwidth is reduced to 300MHz minimum, which remains suitable for standard RGB video applications but represents a 25% reduction from the original specification. The TS5V330DR carries Last Time Buy status, indicating limited future availability.

ADG774BRZ (Analog Devices Inc.) is the manufacturer-recommended substitute with active product status, ensuring long-term availability and supply chain continuity. This part delivers superior electrical performance with 2.2Ohm typical on-state resistance (78% lower than the original specification), enabling reduced signal attenuation and lower power dissipation. The ADG774BRZ supports an extended operating temperature range (-40°C to 125°C), providing additional thermal margin. The -3dB bandwidth of 240MHz is below the original 400MHz specification and represents the lowest bandwidth among available options. The ADG774BRZ is suitable for applications where lower on-state resistance and extended temperature operation are beneficial, though bandwidth-sensitive video applications may require evaluation.

Both substitutes maintain ROHS3 compliance, identical package form factor, and 4-channel configuration. Selection between TS5V330DR and ADG774BRZ depends on prioritization of bandwidth preservation versus long-term availability and superior on-state resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can TS5V330DR directly replace PI5V330WEX in existing designs?

A: Yes, with bandwidth consideration. The TS5V330DR maintains identical on-state resistance (10Ohm), channel count (4), circuit topology (2:1), and RGB bi-directional features. The primary difference is -3dB bandwidth reduction from 400MHz to 300MHz. For standard RGB video switching applications operating below 300MHz, direct substitution is compatible. Applications requiring the full 400MHz bandwidth specification require evaluation or selection of alternative parts.

Q: What are the key differences between TS5V330DR and ADG774BRZ?

A: TS5V330DR prioritizes bandwidth preservation (300MHz) and on-state resistance matching (10Ohm), making it the closest electrical equivalent. ADG774BRZ prioritizes on-state resistance reduction (2.2Ohm typical) and extended temperature operation (-40°C to 125°C), with trade-off of lower bandwidth (240MHz). TS5V330DR has Last Time Buy status; ADG774BRZ has active status with indefinite availability.

Q: Are all three parts pin-compatible?

A: Yes. PI5V330WEX, TS5V330DR, and ADG774BRZ all use 16-SOIC packaging (0.154", 3.90mm width) with identical pinout for 4-channel 2:1 switching configuration. PCB layout modifications are not required for substitution.

Q: Does supply voltage range affect substitution compatibility?

A: The PI5V330WEX operates at fixed 5V supply. TS5V330DR accepts 4V to 5.5V, and ADG774BRZ accepts 3V to 5V. If your design uses regulated 5V supply, all three parts are compatible. If your design operates at voltages outside the 5V nominal range, verify the substitute part's supply voltage specification against your actual supply voltage.

Q: Which substitute should be selected for new designs?

A: ADG774BRZ is recommended for new designs due to active product status, ensuring availability throughout the design lifecycle. The superior on-state resistance (2.2Ohm typical) reduces signal attenuation and power dissipation. Verify that the 240MHz bandwidth meets your application requirements before selection.

Q: What is the impact of on-state resistance differences on circuit performance?

A: Lower on-state resistance reduces signal attenuation and power dissipation. ADG774BRZ at 2.2Ohm typical provides superior performance compared to PI5V330WEX and TS5V330DR at 10Ohm maximum. For video switching applications, this difference typically results in improved signal integrity and reduced thermal load, particularly in high-frequency or high-current switching scenarios.
