Product details
Overview
ISL84467IVZ from Renesas Electronics is a quad SPDT (dual DPDT) analog switch optimized for low-voltage, low-power portable systems. It operates from a single +1.65V to +4.5V supply, delivers 0.39Ω ON-resistance at 4.3V, achieves 33ns turn-on/16ns turn-off times, and supports 1.8V logic compatibility with 3V supply - enabling high-fidelity audio/video signal routing in space-constrained mobile phones and medical handhelds.
For engineers reviewing the ISL84467IVZ datasheet, ISL84467IVZ pinout, ISL84467IVZ application, or ISL84467IVZ equivalent, this page provides verified package mapping (16-lead TSSOP), confirmed dual DPDT configuration, validated break-before-make timing (3ns), real-world leakage specs (±165nA max), and direct alternative part comparisons for signal integrity-critical multiplexer designs.
Technical Context
The ISL84467IVZ implements four independent bidirectional SPDT switches arranged as two synchronized DPDT sections, each controlled by one logic input (IN1–2 and IN3–4). Its CMOS architecture uses level-shifted digital inputs to drive analog gate terminals, ensuring rail-to-rail signal switching across the full 0V to V+ range without bipolar supply requirements.
Break-before-make switching prevents signal shorting during state transitions, while ultra-low rON flatness (0.05Ω) and matching (0.05Ω) minimize channel-to-channel gain error in differential 2:1 mux/demux configurations. ESD protection includes 9kV HBM on COM pins and 6kV on all other I/Os, supporting robust operation in handheld environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPDT (dual DPDT) - enables two independent differential 2:1 multiplexer/demultiplexer functions |
| rON @ 4.3V | 0.39Ω - ensures <0.01dB insertion loss in 50Ω audio paths and minimal THD (0.008%) |
| tON/tOFF | 33ns / 16ns - supports >10MHz analog signal switching with clean edge fidelity |
| Analog Range | 0V to V+ - allows full-rail signal handling without clipping when V+ = 3.3V or 4.2V |

| 5, 6, 11, 14 | COM1–COM4 | Common analog I/O ports - bidirectional signal path shared between NC and NO |
| 7, 8 | IN1–2, IN3–4 | Dual logic control inputs - each drives two SPDT sections simultaneously |
| 9 | GND | Ground reference for analog and digital circuitry - must be low-impedance return path |
| 16 | V+ | Single positive supply (1.65–4.5V) - powers internal CMOS switches and level shifters |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4677ETE+ | 0.5Ω rON @ 3V; 40ns tON; 16-pin TQFN only; no 16-pin TSSOP option | Higher rON degrades THD in audio paths; slower switching limits high-speed data routing | Prefer ISL84467IVZ when TSSOP footprint or <0.4Ω rON is required for precision signal integrity |
| ADG732BRUZ | 0.8Ω rON @ 3V; 16-bit SPI interface; 24-pin TSSOP; higher ICC (100µA) | Digital control adds latency and MCU overhead; larger package increases board area | Choose ISL84467IVZ for simple GPIO-controlled analog routing with minimal layout impact and lowest power |
Compared with MAX4677ETE+ and ADG732BRUZ, the ISL84467IVZ offers the lowest rON in TSSOP packaging, fastest switching with guaranteed break-before-make, and lowest leakage - making it optimal for space-constrained, battery-sensitive analog multiplexing where signal fidelity and power efficiency are co-prioritized.

FAQ
What is the maximum supply voltage rating for ISL84467IVZ?
The absolute maximum supply voltage for ISL84467IVZ is 5.5V, though its operational range is specified from +1.65V to +4.5V. Operating above 4.5V risks exceeding safe internal bias conditions and may degrade reliability or trigger latch-up. The 5.5V rating accommodates transient overshoots on nominal 4.3V rails, as confirmed in the Absolute Maximum Ratings table on page 3 of FN6521 Rev 2.00.
Does ISL84467IVZ support true bidirectional analog signal flow?
Yes, ISL84467IVZ supports fully bidirectional analog signal routing on all COM/NO/NC paths. Each switch conducts equally well from COM to NO or NC, and vice versa, with matched rON and flatness specifications. This is inherent to its CMOS transmission-gate topology and explicitly stated in the "Detailed Description" section on page 11 of the datasheet.
Can ISL84467IVZ be used with 1.8V logic inputs when powered from a 2.5V supply?
No - the ISL84467IVZ's logic threshold is supply-dependent. At V+ = 2.5V, VINH min is 1.2V (per interpolation of Figure 17), below the 1.8V logic high level. For reliable 1.8V logic compatibility, V+ must be ≥3.0V, as confirmed in the "Logic-Level Thresholds" section on page 12 and Table 1 on page 1.
What is the thermal resistance (θJA) of the ISL84467IVZ in its TSSOP package?
The junction-to-ambient thermal resistance (θJA) for ISL84467IVZ in the 16-lead TSSOP package is 115°C/W, measured under standard JEDEC conditions on a low-thermal-conductivity test board. This value is documented in the "Thermal Information" table on page 3 of FN6521 Rev 2.00 and informs derating calculations for continuous 300mA per channel operation.
Is there an exposed thermal pad on the ISL84467IVZ TSSOP package?
No - the ISL84467IVZ TSSOP package (M16.173) does not include an exposed thermal pad. Unlike the TQFN variant (ISL84467IRTZ), the TSSOP version relies solely on lead-frame conduction. The package outline drawing on page 13 confirms no thermal pad feature, and thermal data specifies θJA = 115°C/W without pad-related enhancements.
