ISL8325IB - Dual SPST 60Ohm Analog Switch | Renesas
MPN: ISL8325IB ✓ AktifISL8325IB Genel Bakış
An analog switch is a semiconductor interface device that routes signals between circuit nodes under digital control. The SPST designation means each channel has a single-pole, single-throw arrangement, and 1:1 describes the signal-path configuration. As a dual analog switch, the ISL8325IB provides two switching sections that can be used for signal isolation, sample-and-hold paths, test-point routing, or other analog signal-routing systems. It belongs to the broader semiconductor hierarchy of analog switches, interface ICs, and signal-chain components.
The verified data specifically confirms two circuits, SPST configuration, 60-ohm on resistance, and an 8-pin SOIC package. The data also identifies an industrial temperature grade from distributor listings. Other electrical characteristics, including supply-voltage limits, control thresholds, leakage current, channel capacitance, switching time, and absolute maximum ratings, are not included in the supplied sources and are marked for data confirmation rather than estimated. This conservative approach prevents unverified parameters from being presented as guaranteed design values.
Typical use cases include low-voltage analog signal routing, measurement systems, communication interfaces, and test or control circuits where a digital control signal must select between analog paths. The SOIC-8 footprint is useful for conventional surface-mount PCB assembly. Because an analog switch can influence signal integrity, the input and output routing should be short and appropriately terminated, and control signals should be driven with compatible voltage levels. The 60-ohm resistance should be considered in the context of source impedance, load capacitance, bandwidth, and acceptable insertion loss.
The ISL8325IB is appropriate when the design requires two SPST analog routes and can operate within the verified device limits. Its compact SOIC package and two-channel arrangement can simplify layouts compared with discrete switch implementations. The primary trade-off is that the verified data does not provide enough detail to guarantee off-state isolation, dynamic performance, or power-consumption targets without consulting the complete manufacturer datasheet.
This page combines verified distributor identity, package information, datasheet availability, pricing-source links, and practical selection guidance. It also distinguishes confirmed facts from parameters that require engineering verification. Buyers should compare the complete datasheet, validate logic levels and signal amplitudes, and confirm lifecycle and qualification requirements before releasing a production design.

Tipik Uygulamalar
ISL8325IB için uygundur 6 uygulamas: Low-Voltage Analog Signal Routing, Test and Measurement Signal Selection, Industrial Control Signal Isolation, Low-Voltage Communication Interface Routing, Analog Front-End Channel Selection, Embedded Control and Sensor Interface.
Low-Voltage Analog Signal Routing
The ISL8325IB fits applications that need to route two low-voltage analog paths under digital control. Its verified dual SPST arrangement provides two single-pole, single-throw switching sections, while the confirmed 60-ohm on resistance should be included in the signal-path loss calculation. Use the device when the source and load impedances are compatible with that resistance and the signal amplitude remains within the unverified supply and signal limits. Place the SOIC-8 close to the analog nodes, keep traces short, and verify the official pinout and truth table before layout release.
Önerilen
Test and Measurement Signal Selection
The ISL8325IB can be used to select between low-voltage measurement paths when a system needs two independently controlled analog routes. The dual SPST configuration supports channel isolation, test-point routing, or front-end switching, but the supplied material does not verify capacitance, leakage, bandwidth, or off-state isolation. Those values determine settling time and measurement accuracy. Engineers should model the complete source impedance and load network, validate switching transients with the selected instrumentation, and confirm the manufacturer’s recommended control and supply conditions.
Önerilen
Industrial Control Signal Isolation
The industrial temperature-grade listing makes the ISL8325IB a candidate for industrial control systems that need to isolate or select low-voltage analog signals. The verified 60-ohm on resistance must be checked against the control circuit’s source impedance and load tolerance. Because the provided data does not confirm supply range, logic thresholds, or isolation performance, qualification should include worst-case voltage, temperature, noise, and fault-condition testing. Use a defined ground reference and protect control inputs where industrial transients are possible.
Önerilen
Low-Voltage Communication Interface Routing
The ISL8325IB can route controlled low-voltage signals inside communication equipment when two analog paths must be selected in a compact SOIC-8 footprint. Its two SPST channels provide a straightforward switching architecture for signal isolation or branch selection. The supplied source identifies a 1:1 configuration and 60-ohm resistance, but it does not establish insertion loss, off impedance, or high-frequency behavior. Use short, impedance-controlled routing where applicable, keep switching nodes away from sensitive clocks, and validate the complete interface against its required voltage and timing limits.
Önerilen
Analog Front-End Channel Selection
The ISL8325IB is suitable for selecting one of two low-voltage channels in an analog front end when the design can tolerate the verified 60-ohm series resistance. The dual SPST organization helps avoid separate discrete switch footprints, while the surface-mount SOIC-8 package supports compact assembly. The missing channel-capacitance, leakage, and switching-time data are critical for precision front ends, so evaluate settling, crosstalk, and offset behavior rather than relying only on the nominal resistance. Confirm the official pin configuration and control logic before fabrication.
Önerilen
Embedded Control and Sensor Interface
The ISL8325IB can provide analog path isolation in an embedded controller or sensor interface where two signal routes must be selected under firmware control. Its two SPST channels and 8-pin SOIC-8 package are convenient for compact mixed-signal boards, but the supplied data does not verify logic levels, supply voltage, or leakage. Confirm that the microcontroller output voltage can directly drive the control inputs or add suitable buffering. Validate ground noise, sensor settling time, and switch-induced transients across the intended temperature range.

Ana Farklılayıcılar
- Two-channel SPST analog switching (karşılaştırma:Single-channel or multiplexer devices)
- Confirmed 60-ohm on resistance (karşılaştırma:Lower-resistance switch families)
- Single-supply low-voltage positioning (karşılaştırma:Dual-supply or wider-range switch devices)
Tasarım Notları
Treat the confirmed 60-ohm on resistance as a permanent series element in the selected analog path. Estimate insertion loss from the source impedance, switch resistance, and load, then verify capacitance-driven settling and crosstalk using the complete datasheet values. Keep analog traces short, provide a continuous ground reference, and keep switching control traces away from sensitive analog nodes. Do not infer bandwidth or isolation from the nominal resistance alone.
Confirm the official SOIC-8 pin drawing and pin numbering before placing the footprint; the supplied sources identify the package but do not provide the individual pin names. Route each analog terminal according to the final channel assignment, keep the package away from noisy switching regulators and high-current paths, and provide local ground-return paths. Validate the control traces for voltage levels and timing after reviewing the manufacturer electrical limits.
Do not treat ISL8325, ISL8325IB-T, or related ISL834xx comparison candidates as drop-in parts solely because search results associate them with the family. Verify supply voltage, control thresholds, signal range, leakage, capacitance, switching time, temperature limits, and pinout. The supplied search data contains no complete comparative specification table, so any substitution requires manufacturer documentation or a controlled engineering evaluation.
Uyumluluk Bilgisi
The supplied verified snippets identify an industrial temperature grade but do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Confirm current compliance documentation with Renesas or the authorized distributor.
