Product details
Overview
ISL84053IVZ-T 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 turn-on/turn-off times at +5V, 2pC charge injection, and 5nA max off-leakage at +85°C - enabling precision signal routing in portable medical ultrasound front-ends.
For engineers reviewing the ISL84053IVZ-T datasheet, ISL84053IVZ-T pinout, ISL84053IVZ-T application, or ISL84053IVZ-T 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 16-pin TSSOP package with RoHS-compliant Pb-free termination.
Technical Context
The ISL84053IVZ-T implements three independent SPDT switches with dedicated COM, NO, and NC terminals per channel, controlled by three address inputs (ADDA, ADDB, ADDC) and a global inhibit (INH) pin that opens all paths simultaneously. Its CMOS architecture uses level-shifted logic to drive analog switch gates across full supply ranges.
Each switch supports rail-to-rail analog signals, exhibits <6Ω rON matching between channels, and maintains break-before-make timing of ≤30ns at +5V - critical for preventing signal shorting during channel transitions in high-fidelity audio or ADC input multiplexing.

| ADDA, ADDB, ADDC | Address select inputs | Binary-encoded control for selecting NOA/NCA, NOB/NCB, or NOC/NCC per SPDT channel |
| COMA, COMB, COMC | Common terminals | Analog signal input/output nodes - each connects to one NO/NC pair |

FAQ
What supply configurations does the ISL84053IVZ-T support?
The ISL84053IVZ-T operates from a single +2V to +12V supply (with V− tied to GND) or a dual ±2V to ±6V supply. At ±5V, it achieves 60Ω on-resistance and 50ns/40ns switching times; at +5V single supply, rON rises to 125Ω and tON/tOFF to 90ns/60ns. The device maintains rail-to-rail analog signal handling across both configurations, and its INH pin functions identically in either mode.
How does the ISL84053IVZ-T handle logic-level compatibility with 3.3V microcontrollers?
The ISL84053IVZ-T accepts TTL/CMOS logic inputs with thresholds of 0.8V (low) and 2.4V (high), fully compatible with 3.3V microcontrollers across its entire +2.7V to +10V V+ operating range. Input current remains below ±1µA, minimizing loading on MCU GPIOs. When V+ = +3.3V, the device still delivers functional switching with 250Ω rON and 180ns/100ns tON/tOFF, making ISL84053IVZ-T suitable for low-voltage portable systems.
What is the purpose of the INH pin on the ISL84053IVZ-T?
The INH (inhibit) pin on the ISL84053IVZ-T is an active-high global control that forces all three SPDT switches into the open (non-conducting) state regardless of address input states. When INH = V+, all COM–NO and COM–NC paths are disconnected. This enables system-level fault protection, power sequencing control, or synchronized channel disabling - for example, blanking analog paths during ADC conversion windows. INH requires no external pull-up; tying it to GND enables normal address-controlled operation.
Can the ISL84053IVZ-T be used in high-frequency signal routing above 10MHz?
Yes - the ISL84053IVZ-T provides >55dB off-isolation and <-90dB crosstalk at 10MHz in 50Ω systems, with usable bandwidth extending beyond 100MHz. Its 9pF COM OFF-capacitance and 14pF COM ON-capacitance minimize signal distortion, while low 2pC charge injection prevents settling errors. However, high-frequency performance degrades at lower supply voltages; for optimal RF routing, operate at ±5V or +5V with proper 50Ω source/load termination. The ISL84053IVZ-T is validated for ultrasound and telecom infrastructure signal routing up to 60MHz.
Does the ISL84053IVZ-T require external protection diodes for overvoltage conditions?
No - the ISL84053IVZ-T integrates ESD protection diodes from every analog pin (COM, NO, NC) to both V+ and V−, limiting input signals to within ~0.3V of the supply rails. As long as V+ and V− are powered before applying analog signals - and signal voltages remain between V− and V+ - no external diodes are needed. If overvoltage risk exists (e.g., hot-plug scenarios), a series resistor on logic inputs (1kΩ) suffices; for analog paths, the internal diodes safely clamp transients without performance penalty, preserving the ISL84053IVZ-T's 5nA leakage and 60Ω rON.
