Product details
Overview
ISL84467IRTZ-T from Renesas Electronics is a quad SPDT (dual DPDT) analog switch optimized for low-voltage, battery-powered systems. It delivers 0.39Ω ON-resistance at 4.3V, 33ns turn-on/16ns turn-off times, and operates from +1.65V to +4.5V single supply - enabling high-fidelity audio/video routing in mobile phones and portable medical devices.
For engineers reviewing the ISL84467IRTZ-T datasheet, ISL84467IRTZ-T pinout, ISL84467IRTZ-T application, or ISL84467IRTZ-T equivalent, key selection criteria include rON flatness (±0.05Ω), break-before-make timing (3ns), 1.8V logic compatibility at 3V supply, and ESD robustness (9kV on COM pins).
Technical Context
The ISL84467IRTZ-T 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 gate drive to maintain low rON across the full 0–V+ analog signal range.
Break-before-make switching prevents signal shorting during transitions, while ultra-low charge injection (248pC typ. at 4.3V) and <0.01% THD ensure minimal distortion in audio paths. The device supports 104MHz –3dB bandwidth in 50Ω systems with >65dB off-isolation at 100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rON (4.3V) | 0.39Ω - enables <0.1% insertion loss in 50Ω RF/audio paths |
| tON/tOFF (4.3V) | 33ns / 16ns - supports high-speed multiplexing in portable test equipment |
| rON flatness | ±0.05Ω - ensures channel-to-channel gain matching <0.1dB in differential audio |
| Supply range | +1.65V to +4.5V - powers directly from Li-ion cell (3.0–4.2V) or LDO output |
| ESD rating (COM) | 9kV HBM - withstands handling and system-level ESD without external protection |
| Logic compatibility | 1.8V CMOS at 3V supply - interfaces directly with modern AP/SoC GPIOs |
| ICC (4.2V, 2.85V logic) | 12µA max - contributes <0.1µW static power in always-on sensor mux applications |
Pinout & Package
ISL84467IRTZ-T is packaged in a 16-lead 3×3 mm TQFN (RoHS-compliant, exposed paddle). Pin 1 is marked by an index area; the thermal paddle must be soldered to PCB ground for optimal thermal performance (θJA = 70°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply rail | Accepts +1.65V to +4.5V; powers internal CMOS switches and level shifters |
| GND | Ground reference | Return path for analog signals and digital logic; connects to exposed paddle |
| IN1–2 | Digital control input (Group 1) | Drives SPDT switches 1 & 2; logic "0" ≤0.5V, "1" ≥1.4V (3V supply) |
| IN3–4 | Digital control input (Group 2) | Drives SPDT switches 3 & 4; identical voltage thresholds to IN1–2 |
| COM1–4 | Analog common terminal | Bidirectional signal path; supports full 0–V+ analog swing |
| NO1–4 | Normally open switch terminal | Connected to COM when logic input = "1"; low-capacitance path (102pF) |
| NC1–4 | Normally closed switch terminal | Connected to COM when logic input = "0"; 38pF OFF capacitance minimizes feedthrough |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low rON flatness | ±0.05Ω variation across 0–V+ signal range - preserves linearity in precision sensor muxing |
| Break-before-make timing | 3ns guaranteed delay - eliminates cross-conduction in dual-path audio routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4677ETE+ | Higher rON (0.75Ω @ 3V), larger 16-pin TQFN (4×4mm), no 1.8V logic compatibility | Less suitable for ultra-low-voltage portable audio; requires PCB layout change for footprint | Choose when higher ESD tolerance (15kV HBM) is prioritized over size and low-voltage operation |
| TMUX1574RSVR | Lower rON (0.35Ω @ 3.3V), same 16-pin 3×3mm QFN, but only 1.2V logic compatible | Requires level-shifting for 1.8V GPIOs; better for industrial sensors than consumer audio | Prefer for high-precision instrumentation where rON matching (<0.03Ω) outweighs logic compatibility needs |
Compared with MAX4677ETE+ and TMUX1574RSVR, the ISL84467IRTZ-T uniquely balances ultra-low rON, 1.8V logic compatibility, and 3×3mm footprint - making it optimal for next-gen mobile and wearable designs where board space and battery life are critical.

FAQ
What is the maximum analog signal voltage supported by the ISL84467IRTZ-T?
The ISL84467IRTZ-T supports analog signals from 0V to V+, where V+ ranges from +1.65V to +4.5V. At V+ = 4.5V, the full analog signal range is 0–4.5V. Exceeding V+ or going below GND forward-biases internal ESD diodes, so signals must remain within these rails to avoid leakage or damage.
Does the ISL84467IRTZ-T require external level shifters when interfaced with 1.8V logic?
No. The ISL84467IRTZ-T is 1.8V logic-compatible when operated from a +3V supply: VINL ≤ 0.5V and VINH ≥ 1.4V meet standard 1.8V CMOS thresholds. At 3V supply, its logic inputs accept direct connection to 1.8V GPIOs without level shifting - confirmed in the datasheet's Figure 17 and Electrical Specifications tables.
How does the ISL84467IRTZ-T achieve low charge injection, and why does it matter?
The ISL84467IRTZ-T achieves low charge injection (248pC typical at 4.3V) via matched transistor geometry and optimized gate drive timing. This minimizes voltage glitches on high-impedance nodes - critical in audio DAC/ADC paths and sensor front-ends where pop/click or baseline shift degrades signal integrity.
Can the ISL84467IRTZ-T be used in differential signal applications like USB 2.0 or DisplayPort?
Yes. Its dual DPDT configuration supports differential 2:1 muxing, and its 104MHz –3dB bandwidth, –85dB crosstalk, and 65dB off-isolation at 100kHz meet requirements for USB 2.0 (480Mbps) and DisplayPort Alt Mode signal routing - provided layout follows 50Ω impedance control and tight pair matching.
What thermal considerations apply to the ISL84467IRTZ-T in the 3×3mm TQFN package?
The ISL84467IRTZ-T in 3×3mm TQFN has θJA = 70°C/W (typical). To maintain junction temperature below 125°C, ensure the exposed thermal paddle is soldered to a solid GND plane with ≥4 thermal vias. Power dissipation remains <1mW under typical 100mA switching, so thermal derating is rarely needed in portable applications.
