ISL8393IB - 4-Channel SPST Analog Switch | Renesas
MPN: ISL8393IB ✗ Akhir HayatISL8393IB Ringkasan
An analog switch is an electronic routing component that connects or disconnects analog signals under digital control. A single-pole single-throw, or SPST, switch provides one controlled signal path. The ISL8393 combines four such paths in one package, making it useful for signal routing, test and measurement systems, data acquisition equipment, battery-powered instruments, and communication equipment. In the component hierarchy, it is an analog switch, also described as a CMOS analog switch or interface IC.
The four separately controlled channels provide independent signal-path selection. The Renesas family page identifies pin-compatible replacements for the Maxim MAX391 through MAX393 family and for the DG411, DG412, and DG413 families. Its low 1 micro watt power consumption is particularly valuable in battery-operated equipment, while the 2.5 nA maximum leakage specification helps preserve sensor and measurement accuracy when a channel is disconnected.
Switching performance is optimized for short transition intervals: the family specification lists 60 ns typical turn-on time and 30 ns typical turn-off time. The 35 ohm maximum on-resistance is suitable for general low-voltage signal-routing applications where resistance variation and leakage are more important than very low ohmic values. A 1 ohm channel-to-channel resistance-matching specification helps preserve balance between channels in matched systems.
Typical uses include battery-powered test equipment, portable measurement systems, communication equipment, and analog signal multiplexing arrangements. The wide single- and dual-supply ranges allow the same device family to operate from low single-cell or dual-rail systems. Control signals should be compatible with the selected supply configuration, and unused control or signal pins must follow the manufacturer datasheet guidance.
The principal design trade-off is on-resistance versus power and leakage performance. The ISL8393 prioritizes low power, low leakage, compact integration, and fast switching rather than ultra-low resistance. Designers should verify signal amplitude, bandwidth, charge injection, off isolation, and supply compatibility against the manufacturer datasheet before finalizing a high-precision application.
This page consolidates verified family specifications, manufacturer-supported pin-compatible references, procurement data, comparison parameters, and practical engineering guidance. It distinguishes documented values from parameters that require confirmation from the full datasheet, providing a practical starting point for schematic capture, footprint selection, and replacement planning.

Aplikasi Biasa
ISL8393IB patut untuk 6 aplikasis: Battery-Powered Test Instruments, Portable Data Acquisition Systems, Communication Signal Routing, Analog Signal Multiplexing, Battery-Powered Sensor Acquisition, Industrial Control Signal Isolation.
Battery-Powered Test Instruments
The ISL8393IB fits battery-powered test instruments because its low 1 µW power consumption and 2.5 nA maximum leakage at 85°C limit the burden placed on portable equipment. Four independently controlled SPST paths can route sensors, references, or measurement inputs without requiring a separate switch for every signal. The 35 ohm maximum on-resistance is suitable for many conventional measurement ranges, while 60 ns typical turn-on and 30 ns typical turn-off times support rapid range or path changes. Designers should still verify leakage at the actual operating temperature and confirm that the 35 ohm resistance is acceptable for the source impedance, ADC input, and required accuracy.

Portable Data Acquisition Systems
The four SPST channels of the ISL8393IB support signal multiplexing in portable data-acquisition systems where board area and energy use are constrained. Its single +2 V to +12 V operating range suits low-voltage embedded systems, and the documented 1 µW power consumption is useful when the acquisition system operates from a battery. A designer can use the channels to select external sensors, filters, or calibration references. The key engineering check is the 35 ohm maximum on-resistance, because series resistance can affect high-impedance sensors and the settling behavior of the downstream ADC.
Disebarkan
Communication Signal Routing
The ISL8393IB can route low-voltage communication signals through four independently controlled SPST paths in compact interface equipment. Typical turn-on and turn-off times of 60 ns and 30 ns are fast enough for many control and low-to-moderate-speed routing functions, while TTL compatibility supports conventional digital control interfaces. The 35 ohm maximum on-resistance introduces insertion loss and may affect impedance matching at higher frequencies, so bandwidth and off-isolation must be checked from the manufacturer datasheet. For RF paths above the validated range, a dedicated RF switch is the better architecture.
Disebarkan
Analog Signal Multiplexing
The ISL8393IB is useful as a four-channel analog multiplexer element in systems that must select among several low-level signals. Its 1 ohm channel-matching specification helps maintain consistency between channels, while the family’s 2.5 nA maximum leakage supports measurements where disconnected-node bias must not drift. Four separately controlled switches make the routing architecture straightforward in firmware-controlled instruments. Precision designs should evaluate charge injection and off isolation, neither of which is available in the supplied web excerpts, because switch transitions can create errors even when on-resistance and leakage are acceptable.
Disebarkan
Battery-Powered Sensor Acquisition
The ISL8393IB can connect or disconnect low-level sensor signals in battery-powered acquisition modules. Its low leakage of 2.5 nA maximum at 85°C helps prevent connected and disconnected channels from loading sensitive sensor nodes, while 1 µW power consumption minimizes continuous drain. The device operates from +2 V to +12 V, making it appropriate for low-voltage rails commonly found in compact sensing equipment. Engineer the switched path around the 35 ohm maximum on-resistance and verify that leakage, settling time, and injected charge remain acceptable at the sensor’s impedance and operating temperature.
Disebarkan
Industrial Control Signal Isolation
The ISL8393IB can provide four controllable isolation paths in low-voltage industrial control and test equipment. Independent SPST channels allow a controller to disconnect external lines temporarily, isolate a faulted branch, or route a signal toward a monitoring circuit. Its 1 µW power consumption and low leakage suit compact control boards, while the 2 V to 12 V single-supply range simplifies integration with low-voltage logic. Industrial users must confirm operating-temperature ratings, isolation withstand requirements, and ESD behavior because the supplied excerpts do not establish that the ISL8393IB provides reinforced galvanic isolation.

Catatan Desain
Use the documented 1 µW power-consumption figure as a family-level starting point, not as a complete worst-case design value. Confirm the exact supply condition, control state, signal voltage, and temperature in the manufacturer datasheet. In a battery-powered instrument, even microamp-level differences can dominate standby life, so include the switched-load leakage and any external pull resistors in the complete power budget. Avoid adding pull-up or pull-down networks when they remain continuously energized and defeat the low-power advantage of the switch.
The 35 ohm maximum on-resistance creates a source impedance in the selected signal path. Check its interaction with the receiving circuit’s input impedance, cable capacitance, ADC sample-and-hold behavior, and required settling time. Estimated: with a 10 nF load, an RC network formed by 35 ohm and 10 nF has a 350 ns time constant, so an acquisition path requiring substantially faster settling may need a lower-resistance switch. This estimate must be checked against actual load capacitance, source resistance, and timing requirements.
Place the ISL8393IB close to the switched nodes to minimize PCB trace resistance and susceptibility to injected noise. Route high-impedance signal traces away from clocks, switch-control edges, and power-converter nodes. Keep ground connections short and use a continuous ground plane where practical. Because this is a 16-pin SOIC, verify land pattern, lead pitch, solder mask, and courtyard dimensions against the official package drawing rather than relying only on a generic SOIC footprint.
Do not assume that all four channels can switch signals outside the selected supply rails. The device supports +2 V to +12 V single supply or ±2 V to ±6 V dual supply, and the allowable input and control levels must be checked in the full datasheet. Also verify control polarity before firmware is written, because a family-level pin-compatible claim does not guarantee identical logic functions. For any DG411, DG412, or DG413 substitution, compare absolute maximum ratings, supply behavior, leakage, and switching timing rather than relying only on the 16-pin footprint.
Maklumat Kesediaan
The supplied verified data does not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status for ISL8393IB. AEC-Q100 is not applicable because this is an analog switch rather than an automotive-qualified device.
