ISL83699IV - Quad SPDT Analog Switch, 450mOhm, 16-TSSOP
MPN: ISL83699IV ✓ AktifISL83699IV Ringkasan
An analog switch is a semiconductor interface that routes electrical signals between circuit nodes under digital control. The ISL83699 belongs to the SPDT analog-switch hierarchy, combining four bidirectional SPDT switches, also described as a dual DPDT configuration. This product type supports signal routing in compact, low-voltage electronic systems where fewer GPIO pins, limited board area, and faster switching are important.
The quad-channel architecture provides four selectable signal paths in one package. Each switch has a specified 450 mOhm on-resistance and supports fast switching, with the manufacturer documentation reporting 10 ns tON and 7 ns tOFF. Bidirectional operation allows the same analog path to carry signals in either direction, making the device suitable for shared test, measurement, communication, and signal-routing interfaces.
The ISL83699IV is designed for single-supply operation from +1.65 V to +3.6 V, covering common low-voltage system rails. Its control interface is compatible with 1.8 V logic when the device uses a single +3 V supply. This combination allows a system designer to connect low-voltage digital control signals directly to the switch while maintaining operation from a compact power source.
Typical uses include battery-powered portable equipment, mobile-phone and portable-device signal routing, test-and-measurement systems, and other applications that need to multiplex analog signals through a limited number of external pins. The 16-pin TSSOP package supports surface-mount assembly, while the four-switch configuration consolidates routing functions into one component.
Designers should verify the complete logic levels, signal amplitude, channel configuration, and timing requirements in the Renesas ISL83699 datasheet. Care is especially important when a switched node carries signals near the supply limits, when break-before-make behavior matters, or when control inputs remain active during power sequencing.
This page organizes the switch function, electrical limits, package details, application guidance, verified specifications, and engineering design considerations. It also distinguishes the IV ordering code from related tube, reel, and QFN packaging options so engineers can select the correct orderable configuration without confusing electrical compatibility with mechanical interchangeability.

Aplikasi Umum
ISL83699IV cocok untuk 6 aplikasis: Battery-Powered Portable Device Signal Routing, Mobile Communication Signal Multiplexing, Test and Measurement Equipment, Low-Voltage Sensor Interface Switching, General-Purpose GPIO and Analog Multiplexing, Industrial Control Signal Interconnect.
Battery-Powered Portable Device Signal Routing
The ISL83699IV fits portable systems that need several selectable analog paths while operating from a compact supply. Its four bidirectional 2:1 channels provide more routing capability than individual discrete switches, while the +1.65 V to +3.6 V single-supply range supports low-voltage designs. According to the Renesas ISL83699 datasheet, 450 mOhm on-resistance and 10 ns turn-on behavior help preserve signal integrity when the source impedance is sufficiently low. The device can sit between a sensor, communications block, or peripheral and a shared internal bus, provided switched voltages remain inside the specified limits.
Mobile Communication Signal Multiplexing
The ISL83699IV is appropriate for compact communications equipment requiring multiple bidirectional paths controlled by a low-voltage processor. Its four 2:1 channels can connect separate RF-control, audio, or data lines to shared routing resources without relying on numerous package pins. The manufacturer specifies 450 mOhm on-resistance and switching times of 10 ns turn-on and 7 ns turn-off, which support rapid path selection. The 16-pin TSSOP footprint also offers a practical option for space-constrained boards, although RF signal integrity still depends on trace geometry, return paths, and shielding.
Test and Measurement Equipment
The ISL83699IV can route test signals among multiple sources, instruments, or DUT connections in compact measurement hardware. Four independently addressed SPDT paths reduce the number of discrete relays or mechanical switches needed for basic signal selection. Its bidirectional channels support either source-to-destination or return-path routing, and the 450 mOhm on-resistance is useful where the external circuit presents a substantially higher impedance. For precision measurements, verify leakage, bandwidth, channel isolation, off impedance, and the switch's contribution to the complete error budget before finalizing the front end.
Low-Voltage Sensor Interface Switching
The ISL83699IV is useful when multiple sensor outputs must share a common amplifier, converter, or processor input. The four 2:1 switches allow one control bus to select among several sensor channels, while bidirectional paths support source-following or shared-bus arrangements. Operation from +1.65 V to +3.6 V fits many sensor platforms, and 1.8 V-compatible control supports direct interfacing with low-voltage digital logic. Designers should account for the 450 mOhm on-resistance, leakage, settling behavior, and the sensor output amplitude when calculating gain and error terms.
General-Purpose GPIO and Analog Multiplexing
The ISL83699IV can reduce the pin burden on systems that expose both general-purpose I/O and analog functions through a shared connector. Its four 2:1 channels permit a controller to route compatible signals in either direction, consolidating several switch operations into one 16-pin TSSOP device. The specified 10 ns turn-on and 7 ns turn-off times are suitable for rapid selection, although external pull resistors and connected circuit states can extend practical settling time. Use this arrangement when the signals tolerate the switch resistance and can remain within the device's supply-referenced voltage range.
Industrial Control Signal Interconnect
The ISL83699IV can support compact industrial-control modules that route low-voltage control or diagnostic signals through a common interface. Its industrial temperature grade and single +1.65 V to +3.6 V supply operation align with many embedded controller platforms, while the four-channel configuration consolidates multiple switching functions. The TSSOP package supports automated surface-mount assembly. Before deployment, confirm that transient levels at switched terminals, control thresholds, and grounding arrangements meet the manufacturer's limits, especially when the routed lines originate outside the controlled board boundary.

Catatan Desain
Treat the specified 450 mOhm on-resistance as part of the complete source and load impedance. Estimated insertion loss from the switch resistance for a 50 ohm system is approximately 0.039 dB when calculated as 10log10(1 + 0.45/50). This estimate excludes connector loss, trace loss, capacitance, and impedance discontinuities. Keep switched traces short, use a continuous reference plane, and avoid unnecessary stubs so the package does not become the dominant source of signal degradation.
Do not treat all ISL83699 suffixes as mechanically interchangeable. The ISL83699IV and ISL83699IV-T use the 16-pin TSSOP configuration, whereas the IR variants use a QFN package and require different PCB pads. Before releasing a board, compare the selected manufacturer's pin drawing, package outline, exposed-pad requirements, orientation mark, and tape orientation against the assembly package. This prevents a mechanically incorrect substitution from causing soldering or routing failures.
Operate the switch from a stable supply within +1.65 V to +3.6 V and ensure every switched signal remains within the device's specified signal and absolute-maximum limits. Because the analog paths are bidirectional, an externally driven node can influence behavior regardless of the nominal signal-flow direction. Use series resistance or control sequencing where necessary to limit fault current during power transitions, and do not allow control inputs to exceed the supply level specified for the operating condition.
Place the device near the signals it routes and maintain short, continuous traces for both common and switched terminals. Connect the supply and ground pins with low-impedance traces, and use a solid ground plane beneath the TSSOP footprint. Avoid routing sensitive analog lines beneath or immediately beside fast digital control nets when crosstalk could affect the measurement. The manufacturer pin description and recommended layout should govern the final trace and pad geometry.
