Product details
Overview
ISL84053IAZ-T7A 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 at +5V, <6Ω rON matching, 2pC charge injection, and 5nA max off-leakage at +85°C - ideal for precision signal routing in portable medical ultrasound front-ends.
For engineers reviewing the ISL84053IAZ-T7A datasheet, ISL84053IAZ-T7A pinout, ISL84053IAZ-T7A application, or ISL84053IAZ-T7A equivalent, key selection criteria include rail-to-rail analog signal handling, break-before-make switching, TTL/CMOS logic compatibility at 3.3V/5V, and guaranteed performance across -40°C to +85°C with QSOP-16 packaging.
Technical Context
The ISL84053IAZ-T7A implements three independent SPDT switches with shared digital control: ADDA, ADDB, ADDC select channel state (NCA/NOA, NCB/NOB, NCC/NOC), while INH globally disables all paths. Its CMOS architecture uses level-shifted gate drive to maintain low rON across supply voltages without GND reference in the analog path.
Each switch features break-before-make timing (≤30ns at +5V), 9pF COM OFF-capacitance, and <−90dB crosstalk - enabling high-fidelity signal isolation in multi-channel ATE and imaging systems where channel-to-channel interference must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Triple SPDT analog switch for 2:1 multiplexing per channel |
| ON-resistance (rON) | 60Ω max at ±5V supply - ensures minimal signal attenuation in precision gain-switching networks |
| Switching time (tON/tOFF) | 90ns/60ns max at +5V - supports high-speed multiplexing in real-time data acquisition |
| rON matching | <6Ω between channels - critical for matched-path applications like differential signal routing |
| Charge injection | 2pC typical - reduces voltage glitch in sample-and-hold and integrator reset circuits |
| Off-leakage current | 5nA max at +85°C with ±5V supply - preserves accuracy in high-impedance sensor interfaces |
| Analog signal range | Rail-to-rail (0V to V+ or V− to V+) - enables full dynamic range utilization in ADC/DAC interfaces |
Pinout & Package
ISL84053IAZ-T7A is housed in a 16-lead QSOP package (Pb-free, RoHS compliant, M16.15A drawing), with 0.65mm lead pitch and exposed pad not present. Pin functions are validated per FN6047 Rev.10.00, Page 2 (top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive power supply input | Drives analog switch gates and internal logic; sets upper analog voltage limit |
| V− | Negative power supply input | Drives analog switch gates; connect to GND for single-supply operation |
| GND | Ground reference | Reference for digital inputs only; no analog path connection |
| INH | Inhibit control input | Logic high disables all three SPDT switches simultaneously |
| ADDA, ADDB, ADDC | Channel select address inputs | Binary-coded control: ADDA selects NOA/NCA, ADDB selects NOB/NCB, ADDC selects NOC/NCC |
| COMA, COMB, COMC | Common terminals | Center pins of each SPDT switch; carry routed analog signals |
| NOA, NOB, NOC | Normally open terminals | Connected to respective COM when corresponding ADDx = 1 |
| NCA, NCB, NCC | Normally closed terminals | Connected to respective COM when corresponding ADDx = 0 |
Key Features
| Feature | Design Value |
|---|---|
| Triple SPDT configuration | Enables independent 2:1 signal selection per channel without external logic or routing complexity |
| Break-before-make switching | Guarantees ≤30ns dead time at +5V to prevent momentary short-circuits during channel transitions |
| TTL/CMOS logic compatibility | 0.8V–2.4V input thresholds work directly with 3.3V/5V microcontrollers and FPGAs |
| Rail-to-rail analog signal handling | Supports full-scale signals from V− to V+ - essential for ±5V op-amp interfaces and unipolar DAC outputs |
| Low charge injection (2pC) | Minimizes voltage step errors in precision sample-and-hold and integrator reset applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4583ESE+ | Pin-compatible QSOP-16 triple SPDT; 120Ω rON at +5V (vs. 125Ω typ for ISL84053); 100ns/70ns tON/tOFF | Higher rON increases insertion loss in low-voltage sensor interfaces; suitable for less demanding 5V-only systems | Select MAX4583ESE+ when legacy MAX4583 footprint reuse is required and 60Ω rON is not critical |
| ADG1434BRUZ | 16-lead TSSOP triple SPDT; 4.7Ω rON at ±15V (not rated at ±5V); 125ns/100ns tON/tOFF; requires ≥±5V dual supply | Superior rON but incompatible with 3.3V/5V single-supply operation; higher supply voltage requirement limits portability | Choose ADG1434BRUZ only for high-precision, high-voltage industrial systems where ±15V rails are available |
Compared with MAX4583ESE+ and ADG1434BRUZ, ISL84053IAZ-T7A uniquely balances ultra-low leakage (5nA), wide supply flexibility (2V–12V), and fast switching (90ns) in a QSOP package - making it optimal for battery-powered medical and test equipment where power, precision, and supply headroom are constrained.

FAQ
What supply voltage ranges does the ISL84053IAZ-T7A support?
The ISL84053IAZ-T7A operates from a single +2V to +12V supply or dual ±2V to ±6V supplies. At +5V, it achieves 125Ω typical ON-resistance; at ±5V, rON drops to 60Ω. The device maintains specified performance across the full -40°C to +85°C temperature range under these conditions, and its absolute maximum rating allows transient exposure up to ±15V on V+/V−.
How does the ISL84053IAZ-T7A handle logic-level compatibility with 3.3V microcontrollers?
The ISL84053IAZ-T7A accepts TTL/CMOS logic inputs with guaranteed thresholds of 0.8V (VIL) and 2.4V (VIH) across its entire +2.7V to +10V V+ range. When powered from +3.3V or +5V, its digital inputs interface directly with standard 3.3V microcontrollers without level-shifting - confirmed by FN6047 Section "Digital Input Characteristics" and truth table behavior on Page 4.
Does the ISL84053IAZ-T7A provide break-before-make switching, and what is its timing specification?
Yes, the ISL84053IAZ-T7A guarantees break-before-make operation with a maximum tBBM of 30ns at +5V supply (Page 7, Electrical Specifications). This prevents momentary short-circuiting between NC and NO paths during channel transitions - critical for protecting sensitive downstream circuitry in medical and test equipment.
What is the analog signal bandwidth and isolation performance of the ISL84053IAZ-T7A?
At 10MHz in a 50Ω system, the ISL84053IAZ-T7A provides >55dB off-isolation and <−90dB crosstalk (Figure 18, Page 15). Its 9pF COM OFF-capacitance and high-frequency response support clean signal routing up to 100MHz - verified in Figure 17 - making it suitable for RF sampling and high-speed data acquisition where feedthrough must be minimized.
Can the ISL84053IAZ-T7A be used in single-supply configurations with ground-referenced signals?
Yes. When V− is tied to GND, the ISL84053IAZ-T7A operates as a single-supply device supporting 0V to V+ analog signals. Its COM, NO, and NC pins handle rail-to-rail inputs, and digital logic remains functional since V+ and GND power the internal level shifters - as detailed in the "Power-Supply Considerations" section (Page 13) and Absolute Maximum Ratings (Page 5).
