Product details
Overview
ISL5120IBZ-T from Intersil is a low-voltage, single-supply, dual SPST analog switch with two normally open (NO) channels. It operates from +2.7V to +12V, delivers 19Ω ON-resistance at 5V, 28ns turn-on time, and 10nA max leakage current, enabling high-fidelity signal routing in space-constrained portable systems such as cellular handsets and medical ultrasound front-ends.
For engineers reviewing the ISL5120IBZ-T datasheet, ISL5120IBZ-T pinout, ISL5120IBZ-T application, or ISL5120IBZ-T equivalent, key selection criteria include guaranteed dual NO configuration, SOT-23-8 package compatibility, sub-30ns switching performance at 3.3V/5V/12V, and <5µW quiescent power consumption in battery-powered designs.
Technical Context
The ISL5120IBZ-T implements fully CMOS-based bidirectional analog switches with integrated level shifters that translate TTL/CMOS logic inputs (0.8V/2.4V thresholds) into full-rail gate drive for the internal transmission gates. Its architecture ensures symmetrical analog conduction and minimal charge injection (≤5pC).
Unlike SPDT or mixed NO/NC variants, the ISL5120IBZ-T's dedicated dual-NO topology eliminates break-before-make timing constraints and simplifies control logic in applications requiring parallel signal path enablement-e.g., dual-channel ADC input multiplexing or redundant sensor interface selection.

FAQ
What is the maximum supply voltage rating for the ISL5120IBZ-T?
The ISL5120IBZ-T has an absolute maximum supply voltage of 15V, with recommended operation from +2.7V to +12V. At 12V, its ON-resistance drops to 11Ω typical and switching times improve to 25ns/17ns (tON/tOFF). Operating beyond 12V is not advised for sustained use, as electrical specifications are only guaranteed up to 12V per the FN6022 datasheet.
Does the ISL5120IBZ-T support bidirectional analog signal flow?
Yes, the ISL5120IBZ-T supports fully bidirectional analog signal routing on both channels. Each NO–COM path conducts equally in either direction when enabled, with no polarity restrictions. This enables flexible use in sample-and-hold circuits, operational amplifier gain-switching networks, and other applications requiring reversible signal paths.
What is the guaranteed operating temperature range for the ISL5120IBZ-T?
The ISL5120IBZ-T is specified for operation from –40°C to +85°C, denoted by the "I" grade in its part number suffix. All key parameters-including rON, leakage current, and switching times-are tested and guaranteed across this full industrial temperature range, making it suitable for automotive cabin modules and outdoor industrial sensors.
Can the ISL5120IBZ-T be used with 3.3V logic controllers?
Yes, the ISL5120IBZ-T accepts standard 3.3V logic inputs directly: its input voltage high (VINH) threshold is 2.4V minimum, and input voltage low (VINL) is 0.8V maximum-fully compatible with 3.3V CMOS and TTL outputs. No level-shifting circuitry is needed, simplifying interface design with modern microcontrollers and FPGAs.
Is the ISL5120IBZ-T pin-compatible with earlier Intersil analog switches?
Yes, the ISL5120IBZ-T is a pin-compatible replacement for the ISL84541, as explicitly stated in the datasheet Features section. It retains identical SOT-23-8 pinout, electrical behavior, and footprint, allowing drop-in upgrades to achieve lower rON, faster switching, and improved leakage performance without PCB redesign.
