TS339CN - 16V Micropower Quad CMOS Comparator | STMicroelectronics

STMicroelectronics TS339CN is a micropower quad CMOS voltage comparator with four independent comparison channels, open-drain outputs, and a 14-pin through-hole DIP package. The device operates from a single supply up to 16 V, consumes 9 uA typical per comparator, provides 1 pA typical input offset current, and has input impedance of 10^12 ohms typical. These characteristics make it suitable for low-power sensing, threshold detection, and analog signal conditioning. A voltage comparator is an integrated circuit that compares two input voltages and changes its output state according to their relative polarity. The TS339 belongs to the comparator hierarchy, where a comparator is a type of analog integrated circuit and signal-conditioning semiconductor. Its four channels provide flexible logic-level sensing, while the open-drain outputs allow wired connections or external pull-up networks when a push-pull output is not required. The principal benefits of the TS339CN are its low 9 uA typical supply current per comparator, extremely low 1 pA typical input offset current, and high 10^12 ohm typical input impedance. These characteristics reduce loading on high-impedance sensors and support battery-operated or low-leakage measurement systems. The open-drain architecture also supports wired-AND behavior, provided suitable pull-up resistors and an appropriate supply voltage are used. The TS339CN is designed around a CMOS input stage and four independent comparator channels. Its response time is 1.5 us typical for a 5 mV overdrive condition, making it suitable for many threshold and control functions where microsecond-scale decisions are sufficient. The manufacturer also identifies the device as pin-to-pin and functionally compatible with the bipolar LM339, which can simplify qualification of an existing comparator-based design. Typical uses include battery-powered sensor interfaces, low-voltage monitoring circuits, threshold detection, window comparators formed from pairs of channels, and general control logic. Because the outputs are open-drain, an application must include pull-up resistors whenever a valid high output level is required. The four-channel architecture also allows multiple independent measurements from a single IC. For a new through-hole design, allow adequate clearance around the 14-pin DIP footprint and route sensitive input traces away from switching nodes and output pull-up networks. Input common-mode range, output saturation levels, supply current, and output timing should be checked against the manufacturer datasheet for the intended supply voltage and temperature conditions. This page organizes the key TS339CN specifications, comparison information, practical design notes, and verified sourcing references. It also highlights the device's open-drain output architecture, low-power operation, and LM339 compatibility considerations for engineers evaluating PCB and firmware changes.

TS339ID - Micropower Quad CMOS Comparator | STMicroelectronics

STMicroelectronics TS339ID is a micropower quad CMOS voltage comparator with four independent open-drain outputs, a supply range of ±8 V to ±16 V, and a 14-pin SOIC package. Each comparator typically consumes 9 µA, while the device is designed for low-input-bias and low-input-offset-current measurements. A voltage comparator is an analog semiconductor that compares two input voltages and produces a digital logic result indicating which input is higher. The TS339ID belongs to the comparator hierarchy, combining four general-purpose channels in one package. Its CMOS construction reduces current consumption compared with a conventional bipolar LM339, while the open-drain outputs support wired logic, level translation, and systems using external pull-up resistors. Each channel provides non-inverting and inverting inputs. Key characteristics include extremely low input bias current, a typical input offset current of 1 pA, and typical input impedance of 10^12 ohms. The TS339ID is pin-to-pin and functionally compatible with the bipolar LM339 device. Its typical response time is 1.5 µs for a 5 mV overdrive, making it suitable for threshold detection rather than high-speed signal-chain comparison. The open-drain output architecture requires an external pull-up resistor when a logic-high level is needed. Because the output stage can pull the node low but cannot actively drive it high, several comparator outputs can be combined in a wired-AND arrangement. This characteristic is useful for supervision, window detection, and fault signaling, although circuit design must account for the pull-up value, output leakage, and bus rise time. Typical uses include power-supply sequencing, battery monitoring, overvoltage and undervoltage detection, temperature-control thresholds, industrial sensor interfaces, and simple digital control systems. The quad arrangement reduces board area and component count when four independent thresholds are required, particularly in industrial monitoring, instrumentation, and embedded-control equipment. Designers should verify input common-mode limits, output pull-up requirements, and absolute maximum supply voltage against the manufacturer datasheet before implementation. The open-drain node should include a pull-up to a valid logic rail, and unused inputs must be tied to a defined potential rather than left floating. PCB layout should keep sensitive input traces away from switching nodes and high-current return paths. This product overview combines the exact TS339ID characteristics with practical guidance for open-drain logic, threshold detection, PCB implementation, and comparison against pin-compatible LM339-family devices. It also organizes the available technical information for engineers evaluating power consumption, response time, input impedance, package compatibility, and lifecycle-sensitive redesigns.

The 1.35 V to 16 V supply range allows operation from low-voltage battery systems through conventional industrial rails, while the 1 pA typical input bias current reduces loading on high-impedance sensors. A 5 mV typical input offset voltage defines the baseline comparison accuracy, and the 1.5 microsecond response time supports threshold decisions without adding substantial propagation delay. Each comparator channel operates independently, allowing one device to implement four related decisions. The open-drain output architecture requires an external pull-up resistor, but it also provides flexible output-interface options. Designers can use the pull-up voltage to match downstream logic levels and can connect open-drain outputs in wired-AND configurations where appropriate. Dual-supply operation is supported up to a total supply span of 8 V. Typical uses include industrial sensor interfaces, battery-powered monitoring, digital control thresholds, window comparators, and general signal-conditioning systems. The low input bias current is particularly useful with resistive dividers, sensor outputs, and leakage-sensitive measurement circuits. The 14-DIP format also supports through-hole assembly and repairable industrial equipment where surface-mount packages would be inconvenient. When designing around the TS339IN, account for the open-drain output when selecting pull-up values and external logic supply levels. Keep input and output paths away from noisy switching nodes, and verify offset and common-mode behavior against the minimum signal separation required by the application. The operating range of -40°C to +125°C supports industrial temperature environments when the complete assembly is properly qualified.

A voltage comparator is an analog signal-processing IC that compares an input voltage against a reference voltage and changes its output state when the differential input crosses the switching threshold. A dual comparator integrates two independent channels into one package. Within the broader semiconductor hierarchy, TS372CD belongs to the comparator and amplifier IC family, where it bridges low-power analog sensing and digital logic control. The TS372CD emphasizes low power and precision. The manufacturer specifies a very low supply current of 0.1 mA per comparator, independent of supply voltage. Its extremely low input bias current is typically 1 pA, and its input offset current is also typically 1 pA.

It produces open-drain, TTL-compatible outputs and combines very low supply current with extremely low input bias current. A voltage comparator is an analog integrated circuit that compares two input voltages and changes its output state when the difference crosses a reference level. Comparators belong to the broader interface and signal-conditioning hierarchy, where they convert physical voltage relationships into logic-level events. The TS372CN’s dual-channel architecture provides independent decisions within one package, reducing board area compared with two separate single comparators. Key characteristics include supply current of 0.1 mA per comparator independent of supply voltage, input bias current of 1 pA typical, and input offset current of 1 pA typical. The device operates from a 1.5 V to 8 V single supply or from dual supplies within the stated ±8 V limit. Its open-drain outputs can support TTL-compatible interfacing, while the low-power operation is useful when continuously powered sensing is required. The CMOS input stage is suited to monitoring high-impedance sources because the extremely low bias current minimizes loading of the measured node. Each comparator can evaluate an input against a reference voltage or against the other input when configured as a differential comparator. The manufacturer datasheet should be consulted for the complete electrical characteristics, input common-mode limits, output sink-current limits, and propagation-delay curves. Typical applications include battery-powered threshold detection, sensor-condition interfaces, window comparators, overvoltage and undervoltage indication, low-level signal crossings, and general dual-threshold logic. Two independent channels can also implement hysteresis, zero-cross detection, or a pair of complementary limit checks without requiring two separate IC packages. Designers should account for the open-drain output architecture by providing a pull-up resistor at every output used with subsequent digital logic. Input common-mode voltage, output timing, and supply bypass requirements must remain within the manufacturer’s specified operating limits. Decoupling capacitance should be placed close to the supply pins, while sensitive input traces should be kept short and away from switching nodes.

TS372ID

TS372ID - Dual CMOS Voltage Comparator, 8-SOIC | STMicroelectronics

The STMicroelectronics TS372ID is a low-power dual CMOS voltage comparator in an 8-pin SOIC package. It contains two independent precision differential comparators designed for single-supply operation from 3 V to 16 V or dual-supply operation from plus or minus 1.5 V to plus or minus 8 V. Each comparator offers an open-drain output suitable for TTL-compatible interfacing. A voltage comparator is an analog integrated circuit that compares two input voltages and produces a digital logic state indicating which input is higher. The TS372ID belongs to the comparator category within analog and mixed-signal integrated circuits, where it is used for threshold detection, level sensing, signal conditioning, and simple control decisions. Its dual architecture allows two independent comparisons in one package, reducing component count when two threshold functions are required. The TS372ID uses STMicroelectronics silicon linMOS technology and emphasizes low power consumption. The manufacturer specifies a very low supply current of 0.1 mA per comparator, independent of supply voltage. Its extremely low input bias current is typically 1 pA, and its input offset current is also typically 1 pA, making the device suitable for high-impedance sensing circuits where source leakage could otherwise change the decision point. The wide operating-supply range allows the same device family to support low-voltage single-rail systems or balanced dual rails. Because the outputs are open-drain, each output requires an external pull-up resistor. This arrangement supports wired logic functions and allows the output transition speed to be adjusted through the pull-up resistance and circuit capacitance, but it also means an external pull-up is required to obtain a valid high output state. Typical uses include battery-powered threshold detection, sensor signal conditioning, overvoltage and undervoltage monitoring, window-comparison functions, and low-power control logic. When two comparators operate from the same supply, their individual input, output, and supply pins still require careful routing to avoid unintended coupling or output contention. For layout, place input and output traces away from high-current switching nodes and preserve a short return path to the supply ground. Select pull-up resistors according to the required rise time and available output current, and ensure that the input common-mode range remains within the limits stated in the manufacturer datasheet for the selected supply voltage. Decoupling capacitors should be placed close to the supply pins, with the ground connection kept short. This page organizes the TS372ID supply, input-current, package, output, and application information into an engineering-oriented selection guide. It also documents where to find the official datasheet, how to interpret the package and pinout, what to verify before making a replacement, and how to request a quotation through the XAIPART Request a Quote form.

The device can also participate in line-driver or receiver designs where open-drain outputs are pulled up to a suitable logic supply. In dual-supply systems, it is useful when signals may fall below ground or rise above a midpoint reference. Design the input network so the differential signal remains within the comparator’s specified common-mode operating range, especially when operating from a 3 V single supply.

The device supports single- or dual-supply operation, provides open-drain outputs compatible with CMOS, MOS, and TTL logic, and combines a typical response time of 200 ns with very low power consumption. Its four-channel arrangement allows one package to implement four independent sensing or threshold functions. A voltage comparator is an analog semiconductor that compares two input voltages and changes its output state when the difference crosses a defined threshold. The TS374CD belongs to the comparator hierarchy within analog and interface ICs. Each channel has differential inputs, high input impedance, and an open-drain output that can pull a logic node low. When used with a pull-up resistor, the open-drain architecture supports wired logic, level translation, and direct interfacing with multiple open-drain devices. The principal device characteristics include four independent channels, a typical input impedance of 10^12 ohms, a typical input bias current of 1 pA at 5 V, and a maximum quiescent current of 250 microamperes. The fast typical response time of 200 ns is useful for signal crossing, threshold detection, and control-loop applications where the comparator must react quickly after an input differential changes polarity. Open-drain outputs provide flexible system integration without driving the output high actively. The TS374CD uses four independent precision voltage comparators implemented with STMicroelectronics silicon linear MOS technology. This process is intended to provide a favorable balance between consumption and operating speed. The very high input impedance reduces loading on the signals being measured, while the low typical bias current is beneficial when the comparator monitors high-impedance sensors or threshold networks. Because the output is open drain, its rising voltage is established by an external pull-up resistor rather than an internal active pull-up. Typical applications include sensor-threshold detection, overvoltage and undervoltage monitoring, window comparison, zero-cross detection, industrial control logic, and general-purpose analog signal conditioning. Four channels can also be used as independent comparator elements in a compact design, reducing package count compared with discrete or single-channel implementations. A pull-up resistor should be selected according to the target logic family, bus capacitance, and required rise time. When designing with the TS374CD, account for open-drain behavior and provide a suitable pull-up on every output used by downstream logic. Review input common-mode limits, supply range, output sink current, and propagation timing in the manufacturer datasheet before setting thresholds. Because this ordering code is listed as obsolete, confirm lifecycle status and obtain an approved replacement or a supported availability plan before beginning a new production design.

Its open-drain outputs allow the output node to be pulled up to a compatible supply through an external resistor, which supports wired-AND or wired-OR behavior when several outputs share a node. Typical input offset voltage is low, while the approximately 10^12-ohm typical input impedance minimizes loading on high-impedance sensor and divider networks. Operation from 3 V to 16 V makes the device suitable for 5 V logic systems and higher-voltage industrial interfaces. Maximum quiescent current is listed as 250 uA, reducing the impact of continuous comparator operation.

Typical uses include sensor threshold detection, battery and power-supply monitoring, window comparators, overvoltage and undervoltage protection, signal crossing detection, and four-channel digital conditioning. The 200 ns typical response is suitable for many control and monitoring loops, although propagation-delay variation, input overdrive, and output pull-up resistance must be checked in fast systems. The principal design consideration is the open-drain output. Every used output requires an external pull-up resistor, and the resistor must satisfy the sink-current and rise-time requirements of the connected logic.

The STMicroelectronics TS393CD is a dual micropower CMOS voltage comparator with 9 µA typical supply current per comparator, a 2.5 µs typical response time, and an 8-pin SOIC package. Each channel provides an open-drain output, high input impedance, and compatibility with the electrical behavior of bipolar LM393-class comparators. A voltage comparator is an analog integrated circuit that evaluates two input voltages and changes its output state when their relationship crosses a defined threshold. The TS393 belongs to the comparator hierarchy, where it combines analog signal comparison with digital open-drain output signaling. Two independent channels in one package conserve board area in low-power sensing, monitoring, and control systems. The principal advantages are low power consumption, high input impedance, and a response time suited to general-purpose decision circuits. Each comparator consumes 9 µA typically, while the datasheet describes this as approximately 20 times lower consumption than a bipolar LM393. The open-drain outputs permit wired logic, wired-OR operation, and level translation when an external pull-up resistor is used. The 2.7 V to 16 V supply range supports low-voltage systems while retaining operating temperature coverage from -40 °C to 125 °C. The TS393CD uses CMOS input stages to achieve a typical input impedance of 10^12 ohms. This makes the device suitable for high-impedance sensors and divider networks because the input stage draws very little current. Its maximum input offset voltage of 6.5 mV defines the practical input-referred threshold uncertainty around the comparison point. Although the response time is not as short as that of a dedicated high-speed comparator, 2.5 µs is suitable for envelope detection, threshold supervision, and slow digital control loops. Typical uses include battery-powered sensor conditioning, window or level detection, overvoltage and undervoltage supervision, temperature threshold systems, and industrial control inputs. The two channels can monitor two independent quantities, or they can be used together when a more complex decision or hysteresis arrangement is required. Open-drain outputs are especially useful when multiple comparators must share a common bus. The principal design consideration is the open-drain output. Every output requires a pull-up resistor to the appropriate logic supply, and the selected resistor must satisfy the output's sink-current and rise-time requirements. The input common-mode range, output saturation levels, and pull-up voltage must also be checked against the circuit operating conditions before deployment. This product page combines manufacturer specifications, package and pin information, application guidance, and a focused replacement comparison.

TS393CN - Micropower Dual CMOS Comparator | STMicroelectronics

The STMicroelectronics TS393CN is a micropower dual CMOS voltage comparator featuring two independent comparison channels, open-drain outputs, and a typical supply current of 9 µA per comparator. It is packaged in an 8-pin DIP and is designed as a micropower alternative to the bipolar LM393. Its input impedance is typically 10^12 ohms, while its typical response time is 2.5 µs with 5 mV overdrive. These characteristics make the TS393CN suitable for low-power threshold detection, signal conditioning, and sensing circuits where dual-channel comparison is useful. A voltage comparator is a type of analog interface IC that compares two input voltages and produces a digital logic result indicating which input is higher. In this product hierarchy, the TS393CN is a dual-channel comparator, belonging to the broader comparator and analog interface IC families. Each channel can monitor a sensor, measurement node, or control threshold independently, allowing one package to perform two related comparison functions while consuming only 9 µA typically per channel. The TS393CN offers high input impedance of 10^12 ohms typically, minimizing loading on the circuit being measured. Its 2.5 µs typical response time for 5 mV overdrive provides useful speed for threshold-control applications while retaining the low current consumption associated with CMOS design. Open-drain outputs also support wired-AND, wired-OR, and level-shifting arrangements when suitable pull-up resistors are added. The manufacturer identifies the device as pin-to-pin and functionally compatible with the bipolar LM393. Because both channels are implemented in CMOS, the TS393CN avoids the comparatively high quiescent current of conventional bipolar LM393 implementations. The manufacturer describes its typical consumption as 20 times lower than the bipolar LM393 while retaining similar performance. This makes it particularly attractive in battery-operated equipment where the comparator can remain active continuously without imposing the same continuous bias-current burden as a bipolar counterpart. Typical uses include battery threshold monitoring, window-comparison systems, temperature-limit detection, low-voltage signaling, and general-purpose sensing interfaces. The two independent channels can compare two sensed quantities against separate references or implement complementary threshold decisions. Its 8-pin DIP format also supports through-hole prototyping, educational equipment, repair work, and industrial control assemblies where socketed or leaded components are preferred. Designers should account for the open-drain output architecture by placing a pull-up resistor on each output. Input common-mode range, supply-voltage limits, output sink current, and operating temperature boundaries must be checked against the manufacturer datasheet before final circuit release. The DIP package also requires adequate lead spacing and mechanical clearance from nearby conductors, especially in high-voltage or densely populated assemblies. This page combines the core electrical characteristics of the TS393CN with package information, practical comparator design guidance, and a focused comparison with documented LM393-compatible devices. It is intended to help engineers identify where the micropower CMOS implementation offers a practical advantage without overlooking the open-drain pull-up requirements and application-specific limits of the original design.

TS393ID

TS393ID - Dual Micropower CMOS Comparator | STMicroelectronics

STMicroelectronics TS393ID is a micropower dual CMOS voltage comparator with an operating supply range of 2.7 V to 16 V, typical consumption of 9 µA per comparator, and open-drain outputs in an 8-pin SOIC package. The device contains two independent comparison channels, making it suitable for dual-threshold, window-monitoring, sensing, and low-power signal-conditioning circuits. Its typical supply current is stated as approximately 20 times lower than that of the bipolar LM393, while retaining the familiar open-drain output architecture. A voltage comparator is an analog integrated circuit that compares two input voltages and changes its output state according to their relationship. The TS393ID belongs to the comparator hierarchy within analog and mixed-signal semiconductors. Its CMOS implementation emphasizes low supply current, and its open-drain outputs allow multiple devices to share a common pull-up when wired-AND behavior is required. These characteristics place it between simple threshold logic and more complex analog front ends. The primary features include two independent CMOS comparators, a 2.7 V to 16 V supply range, and 9 µA typical current consumption per comparator. Each output is open drain and requires an external pull-up resistor when a logic-high output is required. The SOIC-8 package provides a conventional surface-mount footprint suitable for compact industrial, consumer, instrumentation, and embedded-control designs. The manufacturer also identifies the TS3702 as a related dual micropower comparator offering similar performance with push-pull CMOS outputs. Electrically, the open-drain stage can pull its output low but cannot actively drive a high level. This gives designers control over rise time through the pull-up resistor and allows several comparator outputs to share a bus. That flexibility is useful in battery-powered equipment where minimizing activity is important, although the external pull-up contributes its own continuous current after an output is released. The two channels can compare different signal pairs or operate together for window supervision. Typical applications include battery-powered threshold detection, sensor signal conditioning, overvoltage and undervoltage indication, temperature-alarm circuits, industrial control interfaces, and low-power monitoring modules. The comparator may be used with op-amp-like input networks, dividers, current sensors, or digital control inputs where the required decision is binary. Because output polarity and timing determine system behavior, both input and output details should be checked against the manufacturer datasheet before final circuit release. A key design consideration is the external pull-up on each open-drain output. Select its resistance to balance noise immunity, switching speed, and power consumption, then confirm that every connected output can safely share the same node. Account for input common-mode limits, supply decoupling, output rise time, and any required hysteresis. The two channels are independent, so grounding or signal-conditioning requirements should be evaluated separately for each comparator. This page combines the TS393ID's verified electrical and packaging characteristics with drop-in candidate evaluation, parameter-by-parameter comparison, sourcing guidance, and practical circuit-design notes. It is intended to accelerate component selection while preserving the need to confirm detailed operating limits and timing behavior against the manufacturer datasheet.

TS393IN

TS393IN - 2-Channel 9 uA CMOS Comparator | STMicroelectronics

The STMicroelectronics TS393IN is a micropower dual CMOS voltage comparator with two independent comparison channels, a typical supply current of 9 uA per comparator, and a typical response time of 2.5 us in an 8-pin DIP package. It provides an open-drain output configuration and is designed as a low-power alternative to the conventional bipolar LM393. A voltage comparator is an analog integrated circuit that compares two input voltages and changes its output state when the non-inverting input rises above the inverting input, or conversely. Within the broader semiconductor hierarchy, the TS393IN belongs to the comparator and amplifier IC class, supporting signal conditioning, threshold detection, sensing, and control applications. Its CMOS construction combines low bias current with high input impedance, helping preserve weak sensor signals. Key features include extremely high input impedance of 10^12 ohms typical, low typical consumption of 9 uA per comparator, and a response time of 2.5 us typical. The device is compatible with bipolar LM393 applications while offering CMOS input behavior. Two independent channels allow simultaneous comparisons or the implementation of window-comparator and independent threshold-detection functions within one package. The open-drain outputs require an external pull-up resistor when the output must reach a defined logic-high voltage. This arrangement supports wired-open-drain logic, level translation, and system designs in which several devices share a bus, provided the pull-up voltage and sink-current limits are checked. Each comparator can also operate in the standard comparator configuration, with one input serving as the threshold and the other accepting the sensed signal. Typical uses include battery-powered sensor interfaces, low-voltage threshold detection, industrial control logic, monitoring systems, and compact embedded equipment. The TS393IN is particularly useful when the signal source has high source impedance and conventional bipolar comparators would load the input. Its low power consumption also benefits longer-running battery systems, although total system current should include pull-up resistors and external circuitry. For PCB layout, place the pull-up resistors close to the open-drain output nets and keep sensitive input traces away from switching nodes and high-current return paths. Confirm the absolute maximum supply voltage, input common-mode range, output sink current, and input protection limits against the manufacturer datasheet before applying either input beyond the recommended operating range. This product page combines the TS393IN electrical characteristics, pin assignment, package information, practical comparator design guidance, application examples, and drop-in replacement analysis to support faster component selection and board-level implementation.

TS393MD

TS393MD - Micropower Dual CMOS Comparator | STMicroelectronics

The STMicroelectronics TS393MD is a micropower dual CMOS voltage comparator with two independent comparison channels, open-drain outputs, and an 8-pin SOIC package. Each channel consumes 9 uA typically, has a typical input impedance of 10^12 ohm, and provides a typical response time of 2.5 us. The device is designed for low-power sensing and control circuits requiring high input impedance. A voltage comparator is an analog integrated circuit that compares an input voltage against a reference voltage and changes its output state when the relationship between those voltages changes. Comparators are used within analog signal chains, embedded control systems, and power management equipment. The TS393 belongs to the comparator family, the amplifier and analog IC hierarchy, and ultimately the broader integrated-circuit and semiconductor categories. The TS393MD provides two CMOS comparator channels in one package, reducing component count in dual-threshold or dual-signal systems. Its open-drain outputs permit wired-AND behavior when suitable pull-up resistors are installed. High input impedance minimizes loading of the sensed source, while the 2.5 us typical response time supports applications that need meaningful response speed without the continuous power demand of a faster bipolar comparator. The 9 uA typical supply current per comparator makes the device suitable for battery-operated instruments, portable monitors, and low-power sensor interfaces. STMicroelectronics describes the TS393 as compatible with the bipolar LM393 architecture, which can simplify comparison with conventional dual-comparator designs. The manufacturer also offers the similar TS3702 as a push-pull-output alternative, although its output topology is not interchangeable with the TS393MD open-drain interface without circuit changes. Typical uses include battery-powered threshold detection, sensor signal conditioning, industrial control inputs, and low-power monitoring systems. In each case, the two channels can monitor independent quantities or provide complementary decisions around a reference voltage. The TS393MD is also suitable where the source impedance is high and the comparator should avoid materially loading the monitored node. Designers should account for the open-drain output when selecting pull-up voltage and resistance. Input common-mode limits, supply-voltage range, offset behavior over temperature, and output sink-current capability must be checked in the manufacturer datasheet before finalizing a circuit. PCB placement should keep the comparator input paths short and away from high-current switching nodes to reduce noise coupling. This page combines the manufacturer device description, distributor package information, practical application guidance, and verified drop-in replacement information. It also identifies the measurable differences among directly compatible SOIC-8 options, helping engineers compare output type, supply current, temperature range, and qualification requirements before making a board-level replacement.

The Texas Instruments TS3A27518ERTWR is a bidirectional 6-channel 1:2 (SPDT) analog multiplexer/demultiplexer with 6.2 ohm on-resistance, 240 MHz bandwidth, and integrated IEC 61000-4-2 ESD protection, housed in a 24-pin WQFN (4x4 mm) package operating from a 1.65 V to 3.6 V single supply. An analog multiplexer is a signal-routing semiconductor that selects one of several input channels and connects it to a common output, functioning as a digitally controlled switch for both analog and digital signals. Within the signal-chain hierarchy, it sits between passive switches and full crosspoint matrices, and belongs to the broader family of interface and analog switch ICs used in power management and signal conditioning subsystems. Key features include low 6.2 ohm typical on-resistance for minimal signal attenuation, 21.5 pF typical switch capacitance, up to 240 MHz bandwidth for high-speed rail-to-rail signal handling, and -62 dB crosstalk and OFF isolation. The device also provides isolation in power-down mode (VCC = 0 V), and 1.8 V logic-threshold-compatible control inputs that allow direct interfacing with low-voltage microcontrollers. Architecturally, the TS3A27518E uses two control pins, each simultaneously controlling three 1:2 multiplexer sections, plus an enable pin that places all outputs in high-impedance mode. Integrated ESD cells rated to IEC 61000-4-2 on the signal pins eliminate the need for external TVS diodes in USB and port-protection designs, and the device is qualified for automotive applications. Typical applications include USB 2.0 high-speed signal switching, audio jack and headset detection, battery-powered portable equipment, and general-purpose analog signal routing in industrial systems. A key design consideration is on-resistance flatness across the signal range: at lower VCC the Ron rises, so budget for insertion loss at 1.65 V operation, and keep stub lengths short to preserve the 240 MHz bandwidth. This page adds value beyond the datasheet by synthesizing distributor pricing tiers, drop-in alternatives, cross-reference data, and practical design notes in one reference.

TS3A44159RGTR

TS3A44159RGTR - 0.45Ω Quad SPDT Analog Switch | TI

The Texas Instruments TS3A44159RGTR is a 0.45-Ω quad-channel single-pole double-throw (SPDT) analog switch housed in a 16-pin VQFN (RGT) 3x3 mm package. Operating from 1.65 V to 4.3 V, it delivers low on-state resistance with excellent Ron matching across four independent 2:1 multiplexers and supports bidirectional signal flow on every channel. Two logic-level control inputs select between the NO/NC paths of all four switches simultaneously, simplifying firmware-driven signal routing. An analog switch is a solid-state semiconductor device that routes analog or digital signals between two or more terminals under the control of a logic-level signal. It belongs to the analog switch and multiplexer family, which sits inside the broader interface IC category of integrated circuits. Quad SPDT switches are commonly used to swap between two sources on four channels at once, an arrangement also called a 2-channel DPDT function in this device. Key features include 0.45 Ω typical on-state resistance, 50 pA typical switch leakage, break-before-make switching to prevent momentary channel cross-connection, and a -3 dB bandwidth greater than 35 MHz. The control inputs are 1.8 V logic-compatible, while supply operation extends from 1.65 V to 4.3 V. ESD protection on the switch pins exceeds 2000 V per the HBM model. Architecturally the part uses CMOS transmission gates with integrated charge-pump-derived well biasing, enabling low Ron and rail-to-rail signal swing on a single positive supply. Ron flatness is held tight across the input common-mode range, which preserves harmonic distortion performance in audio paths. The device draws only microamps of quiescent current, which is essential for battery-powered systems. Typical applications include portable audio routing between headphone jack and Bluetooth receiver, USB 2.0 high-speed signal switching, SPI/I²C bus multiplexing, smartphone audio codec path selection, and PDA or portable media player source switching. Industrial uses include 4-wire resistance measurement multiplexing and analog front-end signal routing. When designing with this part, ensure that the logic-high level on IN1/IN2 exceeds 0.85 x VDD and the logic-low is below 0.15 x VDD to guarantee full CMOS-level switching. Place 0.1 µF bypass capacitors within 5 mm of the VDD pin to keep digital control noise out of the analog path.

TS3A4741DCNR

TS3A4741DCNR - 0.9Ω Dual SPST Analog Switch | TI SOT-23-8

The Texas Instruments TS3A4741DCNR is a 0.9 Ω low on-resistance, low-voltage, single-supply, dual single-pole single-throw (SPST) analog switch housed in an 8-pin SOT-23 (DCN) package. It integrates two independent normally open (NO) switches, each with a 1:1 (SPST) topology, designed for 1.8 V logic compatibility when operated from a single 3 V supply rail. What is an SPST analog switch? An SPST (Single-Pole Single-Throw) analog switch is a solid-state semiconductor device that routes analog signals by electrically connecting or isolating one signal path. The TS3A4741 belongs to the broader category of analog switches and multiplexers, a subfamily of interface ICs used for signal routing in mixed-signal and low-power systems. Compared with mechanical relays, analog switches offer far faster switching speeds, lower power, smaller PCB area, and no mechanical bounce, at the cost of lower absolute voltage and current handling. Key specifications include a 0.9 Ω typical on-resistance (Ron), 1.8 V CMOS-compatible digital logic inputs, rail-to-rail analog signal handling, very low quiescent current, and integrated ESD protection. The two switches operate completely independently, allowing them to be used as separate signal paths or as complementary paths in a single function. The device is fabricated in a CMOS process and supports fast switching speeds, low off-leakage current, and bidirectional analog signal flow. Its small SOT-23-8 footprint and 1.8 V logic compatibility make it well suited to portable and battery-powered designs. Typical applications include audio signal routing in portable devices, switching between two sensors in handheld instruments, power rail multiplexing in low-power systems, and general-purpose signal gating in test equipment and consumer electronics. When designing with the TS3A4741, ensure the analog signal stays within the supply rails to avoid distortion or excessive leakage, and add 0.1 µF decoupling close to VCC. For applications requiring normally closed (NC) switches, use the pin-compatible TS3A4742.

TS3A4751PWR

TS3A4751PWR - 0.9-Ohm Quad SPST Analog Switch | Texas Instruments

The Texas Instruments TS3A4751PWR is a bidirectional, 4-channel, normally-open (NO) single-pole single-throw (SPST) analog switch in a 14-pin TSSOP package. It operates from a single 1.6V to 3.6V supply, delivers a maximum on-state resistance of 0.9 ohm at a 3V supply, and handles rail-to-rail analog signals with fast switching speeds and very low quiescent power. An analog switch is an IC that routes or isolates analog signal paths under digital control. Within the signal-routing hierarchy, the TS3A4751 belongs to the SPST switch family, a subset of analog switches and multiplexers used in signal conditioning and power-management systems. Key features include 0.9-ohm maximum Ron at 3V (1.5-ohm maximum at 1.8V), Ron flatness of 0.4-ohm maximum at 3V, and Ron matching of 0.05-ohm maximum at 3V. The 1.8-V CMOS-compatible digital inputs allow direct interface with low-voltage GPIO when using a 3-V supply, eliminating level-shift circuitry. The device is available in 14-pin TSSOP (PW), 14-pin VQFN (RGY), and 2x2-mm micro X2QFN (RUC) packages. The low Ron supports power-switching and low-distortion signal paths, while rail-to-rail operation preserves full signal swing on 1.8V, 2.5V, and 3.3V rails. Typical applications include low-voltage power switching, audio signal routing in portable devices, battery-powered test points, and general-purpose signal muxing in smartphones, tablets, and industrial sensing modules. Its normally-open configuration makes it suitable for fail-safe, default-disconnected paths. When designing, remember that Ron rises at lower supply voltages: at a 1.8-V supply the maximum Ron is 1.5 ohm, so account for insertion loss and on-resistance flatness in high-fidelity or precision-current paths. According to TI datasheet, the TS3A4751 is the NO-switch counterpart within the TI low-voltage quad SPST family.

TS3A5018PWR

TS3A5018PWR - 10-Ohm Quad SPDT Analog Switch | Texas Instruments

The Texas Instruments TS3A5018PWR is a quad single-pole double-throw (SPDT) analog switch designed to operate from a 1.8V to 3.6V supply in a 16-pin TSSOP (PW) package rated from -40C to +85C. It handles both digital and analog signals, and signals up to V+ can be transmitted in either direction. An analog switch is a semiconductor device that selectively connects or disconnects an analog signal path under digital control. It is a fundamental signal-routing building block in the broader family of multiplexers, demultiplexers, and interface ICs. Analog switches provide a low-resistance path when ON and a high-impedance path when OFF, replacing bulky mechanical relays in audio/video routing, data acquisition, and communication systems. Key features include the wide 1.8V to 3.6V operating range (ideal for battery-powered and 3.3V systems), low 10-ohm ON-state resistance with excellent channel-to-channel matching, and low charge injection that minimizes glitches during switch transitions. All four SPDT switches share a common enable function so the entire device can be disabled to reduce power consumption. The TS3A5018 is built on TI CMOS process technology, providing low quiescent power dissipation and high reliability. Bidirectional signal flow means either of the two throw terminals can serve as the port, essential for multiplexing and demultiplexing on the same hardware. Turn-on and turn-off times are fast, supporting high-speed signal routing in data converters and communication interfaces. Typical applications include audio signal routing in portable devices, battery-powered data acquisition front ends, communication interface switching, and test equipment signal multiplexing. The low power consumption and wide supply range make it well suited for portable and industrial designs. Design consideration: the 10-ohm ON resistance introduces series attenuation in high-impedance circuits, so prefer low-impedance loads or buffer the switched node. Place a 0.1uF decoupling capacitor close to the V+ pin, and use the enable pin in battery designs to cut standby current when switching is idle.

TS3A5018QPWRQ1

TS3A5018QPWRQ1 - 10-Ohm Quad SPDT Analog Switch | Texas Instruments

The Texas Instruments TS3A5018QPWRQ1 is an automotive-qualified (AEC-Q100) quad single-pole double-throw (SPDT) analog switch designed to operate from a 1.8V to 3.6V supply. Packaged in a 16-pin TSSOP (PW), it provides four independent SPDT switches with a low 10-ohm on-resistance, handling both digital and analog signals up to V+ in either direction. An analog switch (also called an analog multiplexer/demultiplexer or bidirectional switch IC) is a semiconductor device that routes analog or digital signals through a MOSFET transmission gate controlled by a digital select input. Analog switches sit within the broader signal-routing hierarchy: analog switch IC -> signal multiplexer -> interface and switching IC -> analog signal chain. They are fundamental building blocks wherever a processor must dynamically reconfigure signal paths without degrading signal integrity. Key features of the TS3A5018QPWRQ1 include the low 10-ohm typical on-resistance, wide 1.8V to 3.6V single-supply operation suited to battery-powered and low-voltage systems, full rail-to-rail signal handling, and break-before-make switching that prevents momentary shorting of signal sources. The Q1 suffix denotes AEC-Q100 qualification for automotive environments, with an extended operating temperature range supporting under-hood and body electronics applications. The device uses CMOS transmission-gate architecture, which keeps on-resistance relatively flat across the signal range and minimizes signal distortion for audio and data-routing tasks. Because signals up to V+ can pass in either direction, the switches work equally well for multiplexing and demultiplexing, such as sharing a codec between microphone and headset paths or switching antenna and test signals. Typical applications include automotive infotainment audio routing, battery-management cell-monitoring multiplexing, portable instrument signal switching, and general-purpose I/O expansion in industrial control boards. Design tip: minimize RON signal loss by keeping source impedance low, and always provide a solid V+ decoupling capacitor (0.1uF close to the pin). Remember that the analog signal range is limited to the 0V-to-V+ supply window; signals outside this range must be blocked or level-shifted.

TS3USB3000MRSER

TS3USB3000MRSER - DPDT USB 2.0/MHL Switch | TI | UQFN-10

The Texas Instruments TS3USB3000MRSER is a double-pole, double-throw (DPDT) analog switch that combines a USB 2.0 High-Speed (480 Mbps) switch and a Mobile High-Definition Link (MHL) switch in a single 10-pin UQFN (RSE) package measuring 1.5 mm × 2.0 mm. It supports a -3 dB bandwidth of 6.1 GHz on the MHL path and operates from a 2.3 V to 4.8 V supply. The device is designed to share a common USB or Micro-USB connector between USB 2.0 data and MHL video signals in mobile phones, tablets, and portable media devices. A USB switch IC is a special-purpose analog multiplexer that routes high-speed differential signals between a single downstream port and two upstream paths (host vs. MHL sink). In the hierarchy of power management and signal routing components, this part belongs to the USB interface IC category, sitting between the connector and the application processor. DPDT switches such as the TS3USB3000 are critical because they must pass 480 Mbps USB signals and up to 3 GHz MHL content with minimal insertion loss, low crosstalk, and high off-isolation. Key features of the TS3USB3000 include low on-resistance (Ron) on the USB data paths, low on-capacitance (Con) for high-bandwidth signal transmission, 1.8-V-compatible select pins for direct GPIO control from a mobile processor, and a quiescent current of approximately 5 uA. The wide supply range (2.3 V to 4.8 V) covers both 3.3 V system rails and the typical 3.8 V Li-ion battery range without additional regulation. The small 1.5 mm × 2 mm UQFN footprint makes it ideal for space-constrained mobile applications. The TS3USB3000 uses a charge-pump-less architecture with simple CMOS logic-level select inputs. The two select pins (S1 and S0 per TI documentation) determine whether the common port is routed to the USB path or the MHL path. Internal ESD protection on the signal pins improves robustness against connector-level transients, which is critical for hot-plug consumer electronics. Typical applications include smartphones and tablets with MHL-enabled video output, automotive infotainment systems that mirror mobile content via USB or MHL, portable media players, and USB/MHL dongles. The wide bandwidth also makes it suitable for any system needing to multiplex two high-speed differential pairs onto a single connector. When designing with this part, place the device as close as possible to the USB/MHL connector to minimize stub lengths and signal-integrity degradation. Use controlled-impedance differential routing (90 ohm) on both sides of the switch, and provide adequate ground stitching vias along the signal path to maintain return-current continuity.

TS507CD

TS507CD - 1.9MHz Precision Rail-to-Rail Op Amp | STMicroelectronics

The STMicroelectronics TS507CD is a single-circuit, high-precision operational amplifier with rail-to-rail input and output operation, a 1.9 MHz gain-bandwidth product, and an 8-SOIC package. It is designed for general-purpose precision signal conditioning and supports stable operation across its supply-voltage range. An operational amplifier is a voltage-feedback amplifier used to amplify, buffer, filter, or compare small analog signals. The TS507 belongs to the operational-amplifier hierarchy within analog ICs and broader semiconductor signal-conditioning systems. Its rail-to-rail input stage accepts signals close to the supply rails, while the rail-to-rail output stage provides useful output swing near both limits. The TS507CD uses precision trimming to achieve low input-offset voltage without external zeroing. Its listed maximum input-offset voltage is 550 µV, and its typical common-mode rejection ratio is 115 dB. A 1.9 MHz gain-bandwidth product supports general-purpose closed-loop operation, while the low 850 µA supply current suits low-power analog systems. The device is specified as a single general-purpose amplifier in an 8-SOIC package. Its operating temperature range is listed as 0°C to 85°C, and its typical output-current capability is 128 mA. These characteristics make it appropriate for precision sensor interfaces, active filters, signal buffers, and portable equipment where low offset and low supply current are more important than high bandwidth. Typical uses include bridge-sensor amplification, transducer-signal conditioning, low-frequency active filters, and buffered analog measurements. Because the amplifier operates rail-to-rail at the input and output, system designers can use more of the available supply range, but common-mode and output-swing limits still require verification under the intended load and supply conditions. When laying out a TS507CD circuit, keep feedback components and the input source connections short, and route high-impedance inputs away from switching nodes. Decoupling capacitors should be placed close to the supply and ground pins. Confirm gain-bandwidth, output-swing, and stability requirements against the actual gain, load, supply voltage, and operating temperature. This page combines the TS507CD device description, package information, application guidance, comparison parameters, and verified sourcing references to help engineers evaluate the amplifier and identify technically suitable alternatives before PCB release.
