Number of circuits: 4 independent switch circuits
Multiplexer configuration: 1:1 (one input to one output per circuit)
Package type: 16-TSSOP form factor with 0.173" width and 4.40mm pitch

Electrical Compatibility Criteria:

On-state resistance must not exceed the application's maximum allowable value
Supply voltage range must encompass the system's operating voltage
Operating temperature range must cover the application's thermal requirements
Channel-to-channel matching (ΔRon) must meet signal integrity specifications

Engineering Selection Recommendations

Direct Functional Replacement (Highest Compatibility):

MAX4523EUE+ is the closest functional equivalent to the ISL43142IV. Both devices share identical on-state resistance (100Ohm specification range), matching switch timing characteristics (80ns/30ns), identical charge injection (1pC), and equivalent crosstalk performance (-90dB @ 100kHz). The MAX4523EUE+ operates within the ISL43142IV's supply voltage envelope and maintains the same operating temperature range (-40°C to 85°C). The primary advantage is active product status and RoHS3 compliance, ensuring long-term availability and regulatory alignment.

Lower On-State Resistance Alternatives:

For applications requiring reduced on-state resistance, the ADG1613BRUZ series (1.1Ohm) provides superior signal integrity with significantly lower resistance and improved channel matching (30mOhm). These parts operate across an extended supply voltage range (3.3V to 16V single supply) and support higher operating temperatures (-40°C to 125°C). The trade-off is increased switch time (156ns/87ns) and higher charge injection (170pC).

Mid-Range Resistance Options:

The ADG4613BRUZ (5.1Ohm) and DG456EQ-T1-E3 (5.3Ohm) offer intermediate resistance values suitable for applications where the ISL43142IV's 65Ohm resistance is excessive but lower-resistance variants are unnecessary. The ADG4613BRUZ maintains compatibility with the ISL43142IV's supply voltage range (3V to 12V), while the DG456EQ-T1-E3 requires higher supply voltages (12V to 36V).

Higher On-State Resistance Alternative:

MAX4713EUE+ (25Ohm) serves applications where moderate resistance is acceptable, offering improved bandwidth characteristics and reduced charge injection compared to the ISL43142IV.

Compliance and Availability:

All recommended substitutes carry RoHS3 compliance and active product status, ensuring regulatory alignment and long-term supply chain stability. Selection should prioritize on-state resistance compatibility with the target application's signal path requirements and supply voltage constraints.

Frequently Asked Questions (FAQ)

Q: Can the ADG1613BRUZ directly replace the ISL43142IV?

A: The ADG1613BRUZ is functionally compatible as a 4-circuit SPST-NO/NC switch in 16-TSSOP packaging. However, its 1.1Ohm on-state resistance differs significantly from the ISL43142IV's 65Ohm specification. Direct substitution is valid only if the application's circuit design accommodates lower resistance. The ADG1613BRUZ's extended supply voltage range (3.3V to 16V) and higher operating temperature limit (125°C) provide additional design flexibility.

Q: What is the primary difference between ADG1613BRUZ, ADG1613BRUZ-REEL, and ADG1613BRUZ-REEL7?

A: These part numbers represent identical electrical specifications with different packaging formats. ADG1613BRUZ is supplied in Tube packaging, ADG1613BRUZ-REEL in Tape & Reel (TR) format, and ADG1613BRUZ-REEL7 in Cut Tape (CT) & Digi-Reel® format. Selection depends on production volume and assembly equipment compatibility. All three variants maintain identical electrical performance and RoHS3 compliance.

Q: Is the MAX4523EUE+ a pin-for-pin replacement for the ISL43142IV?

A: Both devices use the 16-TSSOP package with identical pinout configuration. The MAX4523EUE+ is a pin-for-pin replacement with matching on-state resistance (100Ohm), identical switch timing (80ns/30ns), and equivalent electrical characteristics. This makes it the preferred substitute for direct board-level replacement without circuit redesign.

Q: Why does the DG456EQ-T1-E3 require higher supply voltages than the ISL43142IV?

A: The DG456EQ-T1-E3 is optimized for higher-voltage applications, with a minimum supply voltage of 12V (single supply) compared to the ISL43142IV's 2.7V minimum. This design choice enables extended voltage range operation (up to 36V) and improved performance characteristics at higher supply levels. Applications operating below 12V cannot use this device without external voltage regulation.

Q: What does Channel-to-Channel Matching (ΔRon) represent, and why is it important?

A: Channel-to-Channel Matching (ΔRon) specifies the maximum resistance variation between the four independent switch circuits within a single device. The ISL43142IV guarantees 2Ohm maximum matching, while the ADG1613BRUZ provides tighter matching at 30mOhm. Tighter matching improves signal uniformity across multiple channels and reduces crosstalk effects in multiplexed applications.

Q: Can I use the ADG5413BRUZ in a 5V single-supply application?

A: No. The ADG5413BRUZ requires a minimum supply voltage of 9V (single supply) or ±9V (dual supply). It is not suitable for 5V applications. For 5V operation, use the MAX4523EUE+, ADG4613BRUZ, or ADG1613BRUZ series, all of which support lower supply voltages.

Q: What is the significance of RoHS3 compliance for new designs?

A: RoHS3 compliance indicates the device meets current regulatory requirements for hazardous substance restrictions in electrical and electronic equipment. The ISL43142IV is RoHS non-compliant, making it unsuitable for new designs targeting markets with RoHS enforcement. All recommended substitutes carry RoHS3 compliance, ensuring regulatory alignment and market acceptance.
