Product details
Overview
ISL43L210IHZ-T7A from Intersil is a single-pole/double-throw (SPDT) analog switch optimized for ultra-low on-resistance (0.34 Ω at 4.3 V), fast switching (tON = 7 ns, tOFF = 3 ns), and single-supply operation from +1.1 V to +4.5 V. It serves as a bidirectional signal path selector in battery-powered portable systems, delivering guaranteed break-before-make timing and 1.8 V CMOS logic compatibility at 3 V supply.
For engineers reviewing the ISL43L210IHZ-T7A datasheet, ISL43L210IHZ-T7A pinout, ISL43L210IHZ-T7A application, or ISL43L210IHZ-T7A equivalent, this device supports high-fidelity audio/video routing, low-distortion sensor multiplexing, and space-constrained ASIC I/O expansion where sub-1 Ω RON, <10 ns transition times, and SC70 footprint are critical.
Technical Context
The ISL43L210IHZ-T7A implements a committed SPDT topology with one normally open (NO) and one normally closed (NC) channel, enabling both switching and 2:1 multiplexer functions. Its submicron CMOS process delivers precise RON matching (≤0.003 Ω) and flatness (≤0.08 Ω) across the full analog signal range (0 V to V+).
Internal level shifters translate 1.8 V-compatible digital inputs (VINH ≥1.4 V, VINL ≤0.5 V at 3 V) into full-rail gate drive for the analog switches. ESD protection diodes (HBM >6 kV) are integrated on all I/O pins, requiring proper supply sequencing-V+ must be applied before analog or digital signals to avoid forward-biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.1 V to +4.5 V single supply - enables direct integration with Li-ion, coin-cell, and low-voltage logic rails without level-shifting. |
| ON Resistance (RON) | 0.34 Ω at V+ = 4.3 V - minimizes insertion loss and voltage drop in precision analog paths and high-current audio routing. |
| RON Matching | 0.003 Ω max - ensures matched gain/attenuation between NO and NC channels in differential or ratiometric applications. |
| Switching Speed | tON = 7 ns / tOFF = 3 ns at V+ = 3.9 V - supports high-speed data acquisition, burst-mode signal routing, and RF front-end control. |
| Break-Before-Make Delay | 1–3 ns - prevents momentary short-circuit between NO and NC during state transitions, critical for power domain isolation. |
| Leakage Current | ±100 nA max (NO/NC OFF, COM ON) - preserves signal integrity in high-impedance sensor interfaces and battery-monitoring circuits. |
| Package | 6-lead SC70 (2.15 mm × 1.35 mm × 0.95 mm) - reduces PCB area by >50% vs. SOT-23 while maintaining thermal resistance of 590°C/W. |
Pinout & Package
ISL43L210IHZ-T7A is housed in a Pb-free 6-lead SC70 package (JEDEC MO203AB, Intersil P6.049). The package features gull-wing leads, 0.65 mm pitch, and a nominal body size of 2.15 mm × 1.35 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital Control Input | CMOS-compatible logic input; accepts 0.5 V low / 1.4 V high thresholds at 3 V supply; drives internal level shifter. |
| 2 (V+) | Positive Supply Rail | Single analog/digital supply input; powers internal switches, logic, and level shifters; absolute max = +4.7 V. |
| 3 (GND) | Ground Reference | Common return for analog signal paths, digital logic, and ESD protection diodes; must be low-impedance. |
| 4 (NO) | Normally Open Switch Terminal | Analog path connected to COM only when IN = logic high; supports bidirectional signal flow up to ±150 mA. |
| 5 (NC) | Normally Closed Switch Terminal | Analog path connected to COM only when IN = logic low; shares same RON, leakage, and capacitance specs as NO. |
| 6 (COM) | Common Analog Terminal | Shared I/O node for SPDT function; handles full analog signal range (0 V to V+) and charge injection <25 pC. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RON | 0.34 Ω at 4.3 V enables <0.1% gain error in 50 Ω video/audio lines and <1 mV drop at 100 mA load current. |
| Guaranteed Break-Before-Make | 1–3 ns delay prevents signal shorting during switching - essential for avoiding glitches in power-sensitive analog chains. |
| Low Charge Injection | 25 pC max minimizes voltage step artifacts at COM during switching - critical for sample-and-hold and ADC front-end designs. |
| High Off Isolation | −70 dB at 100 kHz ensures >3 mV crosstalk suppression in multi-channel audio routing and sensor multiplexing. |
| Pb-Free SC70 Packaging | RoHS-compliant 6-lead SC70 footprint (P6.049) supports automated assembly and meets IPC/JEDEC J-STD-020 MSL3 reflow profiles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4714ETA+ | Pin-compatible drop-in replacement per datasheet; identical RON (0.34 Ω), tON/tOFF, and SC70-6 package; slightly lower ESD rating (HBM >4 kV vs. >6 kV). | Same use cases but less robust in high-ESD environments (e.g., handheld test gear exposed to user handling). | Select MAX4714ETA+ if legacy design validation exists and ESD margin above 4 kV is sufficient. |
| TMUX1574DSGR | Higher supply range (1.08–4.5 V); lower RON flatness (0.03 Ω); higher leakage (±250 nA); same SC70-6 footprint but different pinout (IN/COM swapped). | Not pin-compatible; requires PCB layout change; better for ultra-low-distortion audio but unsuitable for space-constrained drop-in upgrades. | Choose TMUX1574DSGR only for new designs prioritizing RON flatness over layout reuse or leakage-critical medical sensing. |
Compared with MAX4714ETA+, ISL43L210IHZ-T7A offers superior ESD robustness and identical performance in RON and speed; versus TMUX1574DSGR, it trades slightly higher RON flatness for guaranteed pin compatibility, lower leakage, and proven field reliability in portable consumer electronics.

FAQ
What is the minimum operating supply voltage for ISL43L210IHZ-T7A?
The ISL43L210IHZ-T7A operates down to +1.1 V, enabling compatibility with deeply discharged lithium coin cells and low-power microcontrollers. At this voltage, RON rises to 3.5 Ω and tON increases to 28 ns, but the device remains fully functional and guaranteed per datasheet specifications across −40°C to +85°C.
Does ISL43L210IHZ-T7A support break-before-make switching?
Yes, ISL43L210IHZ-T7A guarantees break-before-make operation with a 1–3 ns delay between channel turn-off and turn-on. This prevents momentary shorting between NO and NC terminals, which is essential for protecting downstream circuitry in power-switching and signal-routing applications.
Can ISL43L210IHZ-T7A be used with 1.8 V logic levels?
Yes - at a +3 V supply, ISL43L210IHZ-T7A accepts 1.8 V CMOS logic inputs (VINH ≥1.4 V, VINL ≤0.5 V). Its internal level shifter ensures reliable switching even with marginal logic margins, making it ideal for interfacing with modern low-voltage FPGAs and application processors.
What is the thermal resistance (θJA) of ISL43L210IHZ-T7A in its SC70 package?
The ISL43L210IHZ-T7A has a typical junction-to-ambient thermal resistance (θJA) of 590°C/W in the 6-lead SC70 package, measured on a high-thermal-conductivity test board in free air. This value reflects the package's compact size and limited copper exposure; thermal design should include local ground pour and minimal trace length for high-current analog paths.
Is ISL43L210IHZ-T7A RoHS compliant and Pb-free?
Yes, ISL43L210IHZ-T7A is RoHS compliant and Pb-free, using 100% matte tin-plated terminations and lead-free molding compounds. It meets IPC/JEDEC J-STD-020 reflow requirements for Pb-free processes and is rated MSL3, supporting standard surface-mount assembly without special handling.
