Product details
Overview
ISL43L410IRZ-T from Intersil is a bidirectional, double-pole/double-throw (DPDT) analog switch optimized for low-voltage portable systems, featuring 0.25Ω ON-resistance at +3V, 12ns turn-on time, and single-supply operation from +1.65V to +3.6V. It integrates an inhibit pin to simultaneously disable all signal paths and supports 1.8V logic compatibility when powered from +3V - enabling use in cellular phone ASIC interface expansion and differential 2-to-1 multiplexing.
For engineers reviewing the ISL43L410IRZ-T datasheet, ISL43L410IRZ-T pinout, ISL43L410IRZ-T application, or ISL43L410IRZ-T equivalent, this device delivers ultra-low RON, guaranteed break-before-make timing, sub-60nA leakage, and dual small-form-factor packaging (3×3mm thin DFN or MSOP), making it critical for space-constrained, battery-powered audio/video switching and medical sensor front-ends.
Technical Context
The ISL43L410IRZ-T implements a committed DPDT architecture with two normally open (NO) and two normally closed (NC) switches per pole, configured for differential 2:1 multiplexing. Its CMOS transmission gate design uses level-shifted digital inputs to drive analog paths across the full supply range.
It guarantees break-before-make operation (tD ≥ 2ns), exhibits RON flatness of 0.03Ω over the signal range, and maintains RON matching ≤ 0.03Ω between channels - ensuring minimal gain error and crosstalk (< −95dB) in precision signal routing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance (RON) | 0.25Ω at V+ = +3.0V - enables <0.1% insertion loss in 50Ω systems and preserves signal integrity in high-fidelity audio paths |
| Turn-On / Turn-Off Time | 12ns / 5ns at V+ = +2.7V - supports >30MHz bandwidth and fast channel switching in portable test equipment |
| Supply Voltage Range | +1.65V to +3.6V - allows direct interfacing with Li-ion battery discharge profiles and 1.8V/3.3V logic domains |
| RON Matching | ≤0.03Ω between channels - ensures matched gain and phase response in differential signal paths |
| ESD HBM Rating | >9kV - provides robust handling margin for assembly in handheld device manufacturing lines |
| Leakage Current | ±60nA max over temperature - minimizes DC offset drift in medical sensor front-end multiplexing |
| Logic Compatibility | 1.8V input thresholds (VINH ≥1.4V, VINL ≤0.5V at +3V supply) - eliminates need for level shifters in mixed-voltage SoC interfaces |
Pinout & Package
ISL43L410IRZ-T is packaged in a Pb-free, 10-lead 3×3mm thin DFN (TDFN) with exposed thermal pad (pkg drawing L10.3x3A). Pin 1 is marked by a dot; pin numbering follows standard counter-clockwise top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive power supply input | Bias source for internal CMOS switches and level shifters; must be applied before any analog/digital signals to avoid ESD diode conduction |
| GND | Ground reference | Return path for analog signal currents and digital logic; forms low-impedance reference for RON stability and THD performance |
| INH | Inhibit control input | Active-high enable: logic high (≥1.4V) forces all switches open; used for system-level power gating or fault-safe shutdown |
| ADD | Address select input | Controls pole selection: logic low connects COM to NC pins; logic high connects COM to NO pins - defines DPDT switching state |
| COM1, COM2 | Analog common terminals | Signal input/output nodes shared between NO and NC paths; rated for ±300mA continuous current and ±500mA pulsed current |
| NO1, NO2 | Normally open analog terminals | Connected to respective COM pin only when ADD = high; exhibit 115pF OFF capacitance and <2pC charge injection |
| NC1, NC2 | Normally closed analog terminals | Connected to respective COM pin only when ADD = low; provide fail-safe signal continuity during logic low states |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RON flatness | 0.03Ω variation across full analog signal range (0V to V+) - ensures linear gain response in audio and sensor signal chains |
| Guaranteed break-before-make | Minimum 2ns delay between channel disconnect and reconnect - prevents momentary short-circuits in power-sensitive multiplexer designs |
| Low power consumption | <0.2µW quiescent power at V+ = +3V - extends battery life in always-on portable monitoring devices |
| High off-isolation | 68dB at 100kHz in 50Ω systems - suppresses interference between active and inactive signal paths in multi-channel audio routing |
| Pb-free RoHS compliance | Pb-free plus anneal process with 100% matte tin termination - compatible with SnPb and Pb-free reflow profiles per IPC/JEDEC J-STD-020 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX1574RTER | Higher RON (0.5Ω @ 3V), no inhibit pin, 12-bit precision grade | Targeted at precision data acquisition, not portable low-power systems | Choose TMUX1574RTER only if higher voltage tolerance (5.5V) and rail-to-rail analog range are required over ultra-low RON |
| ADG732BRUZ | 32-channel SPST (not DPDT), 4Ω RON @ 3V, no break-before-make guarantee | Designed for high-channel-count digital I/O expansion, not differential signal routing | Select ADG732BRUZ only when scaling to >4 switch poles is needed and RON flatness is non-critical |
Compared with TMUX1574RTER and ADG732BRUZ, the ISL43L410IRZ-T uniquely combines DPDT topology, sub-0.3Ω RON, integrated inhibit control, and guaranteed break-before-make - making it irreplaceable for compact, low-voltage differential multiplexing where signal fidelity and power efficiency are co-constrained.

FAQ
What is the maximum supply voltage rating for the ISL43L410IRZ-T?
The ISL43L410IRZ-T has an absolute maximum supply voltage (V+ to GND) of 4.7V. Its operational range is +1.65V to +3.6V, with the 4.7V rating providing margin for transient overshoot and noise spikes on 3.6V rails. Exceeding 4.7V risks permanent damage due to internal ESD diode conduction.
Does the ISL43L410IRZ-T support true break-before-make switching?
Yes, the ISL43L410IRZ-T guarantees break-before-make operation with a minimum delay (tD) of 2ns across the full temperature range (−40°C to +85°C). This prevents momentary short-circuits during pole transition and is verified in the datasheet's Electrical Specifications table under "Break-Before-Make Time Delay".
Can the ISL43L410IRZ-T operate from a 1.8V supply?
Yes, the ISL43L410IRZ-T operates down to +1.65V. At +1.8V supply, typical RON is 0.4Ω and switching times are 22ns/9ns (tON/tOFF). Performance degrades gradually below 2.0V, so design validation at the target supply is recommended per Figure 13 and Figure 14 in the datasheet.
What package type does the ISL43L410IRZ-T use, and is it RoHS compliant?
The ISL43L410IRZ-T uses a 10-lead 3×3mm thin DFN package (drawing L10.3x3A) with exposed thermal pad and Pb-free plus anneal construction. It is fully RoHS compliant, using 100% matte tin termination and materials qualified for both SnPb and Pb-free soldering per IPC/JEDEC J-STD-020.
How does the INH pin function in the ISL43L410IRZ-T?
The INH (inhibit) pin is an active-high digital control input. When pulled to V+, all four analog switches (NO1/NC1/NO2/NC2) are forced open regardless of the ADD pin state - providing system-level signal isolation. For normal operation, INH must be tied to GND. The pin accepts 1.8V logic levels when V+ = +3V.
