Product details
Overview
ISL84053IVZ from Intersil is a triple single-pole/double-throw (SPDT) analog switch configured for 2-to-1 multiplexing, operating from single +2V to +12V or dual ±2V to ±6V supplies. It delivers 60Ω ON-resistance at ±5V, 90ns/60ns tON/tOFF switching at +5V, and 5nA max off-leakage at +85°C, enabling precision signal routing in portable medical ultrasound front-ends and telecom infrastructure channel selection.
For engineers reviewing the ISL84053IVZ datasheet, ISL84053IVZ pinout, ISL84053IVZ application, or ISL84053IVZ equivalent, key selection criteria include its rail-to-rail analog signal handling, break-before-make timing (30ns max at +5V), TTL/CMOS logic compatibility across 3.3V/5V supplies, and triple SPDT topology optimized for redundant signal path switching.
Technical Context
The ISL84053IVZ implements three independent SPDT switches with shared digital control logic, each featuring CMOS transmission gates driven by level-shifted address inputs (ADDA, ADDB, ADDC) and a global inhibit (INH) pin that forces all paths open simultaneously. Its architecture supports both unipolar and bipolar supply configurations without internal GND reference in the analog path.
Switch operation follows strict break-before-make timing (≤30ns at +5V) to prevent momentary shorting between NC and NO terminals. Charge injection is limited to 2pC, and off-capacitance is 9pF per COM terminal - critical for maintaining signal integrity in high-frequency multiplexed ADC/DAC interfaces up to 100MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Triple SPDT analog switch for 2:1 signal path selection per channel |
| ON-resistance (rON) | 60Ω max at ±5V supply - ensures minimal signal attenuation in precision sensor interfaces |
| Switching time (tON/tOFF) | 90ns/60ns max at +5V - enables high-speed channel scanning in ATE systems |
| Off-leakage current | 5nA max at +85°C with ±5V supply - preserves accuracy in low-current sample-and-hold circuits |
| Analog signal range | Rail-to-rail (0V to V+ or V− to V+) - supports full-scale input in single-supply data acquisition |
| Logic compatibility | 0.8V–2.4V thresholds at 2.7V–10V V+ - interoperable with 3.3V and 5V microcontrollers without level shifters |
| Charge injection | 2pC typical - minimizes voltage glitch in integrator reset and switched-capacitor applications |
Pinout & Package
ISL84053IVZ is housed in a 16-lead TSSOP package (Pb-free, RoHS compliant) with 0.65mm lead pitch and exposed thermal pad. The package supports reflow soldering per Intersil's Pb-Free Reflow Profile and has θJA = 110°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive power supply | Drives analog switch gates and internal logic; sets upper analog signal limit |
| V− | Negative power supply | Required for dual-supply operation; sets lower analog signal limit; connect to GND for single-supply use |
| GND | Ground reference | Reference for digital inputs only; no connection to analog signal path |
| INH | Inhibit control | Active-high global disable: drives all switches open when pulled to V+ |
| ADDA, ADDB, ADDC | Address select inputs | Binary-encoded control of NC/NO selection per SPDT channel (e.g., ADDA=0 selects NCA) |
| COMA, COMB, COMC | Common terminals | Three independent analog inputs/outputs - each connects to selected NC or NO path |
| NOA, NOB, NOC | Normally-open terminals | Signal paths closed when corresponding address bit = 1 |
| NCA, NCB, NCC | Normally-closed terminals | Signal paths closed when corresponding address bit = 0; provides default path during power-up or INH assertion |
Key Features
| Feature | Design Value |
|---|---|
| Triple SPDT topology | Enables simultaneous 2:1 selection across three independent signal chains - ideal for redundant sensor inputs or dual-path audio routing |
| Break-before-make timing | Guaranteed ≤30ns at +5V prevents cross-conduction during switching - essential for protecting downstream amplifiers in medical imaging front-ends |
| rON matching | <12Ω max mismatch between channels at ±5V - ensures consistent gain and phase response in multi-channel instrumentation |
| Low charge injection | 2pC typical - eliminates measurable settling error in high-impedance integrator reset circuits used in CT scanner signal conditioning |
| Single/dual supply flexibility | +2V to +12V or ±2V to ±6V operation - simplifies power architecture in mixed-signal systems with legacy ±5V rails and modern 3.3V logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4053ESE+ | Pin-compatible, same triple SPDT function, but 125Ω rON at +5V vs ISL84053IVZ's 125Ω (typical 125Ω, max 225Ω); 100ns tON at +5V | Suitable for lower-speed industrial I/O where 100ns switching suffices; less optimal for >1MHz multiplexed ADC sampling | Select MAX4053ESE+ when legacy design reuse or second-source qualification is required, accepting higher rON and slower switching |
| 74HC4053PW | Pin-compatible CMOS analog switch; 120Ω rON at +5V, 200ns tON, no dual-supply support - operates +2V to +10V only | Limited to single-supply systems; unsuitable for ±5V signal conditioning or rail-to-rail bipolar inputs | Choose 74HC4053PW for cost-sensitive consumer electronics with 3.3V/5V-only signal chains and relaxed speed requirements |
Compared with MAX4053ESE+ and 74HC4053PW, ISL84053IVZ offers superior dual-supply capability, faster switching (90ns vs ≥100ns), and guaranteed low leakage (5nA vs 10nA) - making it the preferred choice for precision medical and telecom signal routing where supply flexibility and signal integrity are critical.

FAQ
What supply voltage ranges does the ISL84053IVZ support?
The ISL84053IVZ operates from a single +2V to +12V supply or dual ±2V to ±6V supplies. When using single-supply mode, V− must be connected to GND. Absolute maximum ratings allow V+ to V− up to 15V, providing margin for 12V supply tolerance and noise spikes. Performance specifications such as rON and switching times are characterized across these ranges.
How does the INH pin function on the ISL84053IVZ?
The INH (inhibit) pin on the ISL84053IVZ is an active-high global control that forces all three SPDT switches into the open state regardless of address input states. When INH is pulled to V+, all COM-to-NO and COM-to-NC paths disconnect. During normal operation, INH must be tied to GND. This feature enables system-level fault protection and synchronized channel disabling in safety-critical applications like medical imaging.
What is the maximum allowable analog signal voltage range for ISL84053IVZ?
The ISL84053IVZ supports rail-to-rail analog signals: from V− to V+ in dual-supply mode, or from GND to V+ in single-supply mode. Input voltages exceeding these limits forward-bias internal ESD diodes, so signals must remain within (V− − 0.3V) to (V+ + 0.3V). For example, with ±5V supplies, the safe analog range is −5.3V to +5.3V; with +5V/GND, it is 0V to +5.3V.
Does ISL84053IVZ require external level-shifting for 3.3V logic control?
No, ISL84053IVZ does not require external level-shifting for 3.3V logic control. Its digital inputs (INH, ADDA–ADDC) have TTL/CMOS-compatible thresholds (0.8V low, 2.4V high) validated over V+ = 2.7V to 10V. When powered from +3.3V or +5V, standard 3.3V microcontroller GPIOs directly drive the address and inhibit pins without additional circuitry.
What is the thermal resistance of the ISL84053IVZ in its TSSOP package?
The ISL84053IVZ in the 16-lead TSSOP package has a junction-to-ambient thermal resistance (θJA) of 110°C/W and junction-to-case (θJC) of 33°C/W, measured under standard JEDEC conditions. These values assume mounting on a high-thermal-conductivity PCB with adequate copper pour. The package's exposed thermal pad must be soldered to a ground plane for optimal heat dissipation in continuous 30mA-per-channel operation.
