TPS8802DCPR - Smoke Alarm AFE with CO Support | TI

The Texas Instruments TPS8802DCPR is a smoke-alarm analog front end (AFE) for residential smoke detectors, integrating the regulators, amplifiers, and drivers required for a dual-wave photoelectric smoke alarm and carbon monoxide detection system. The verified distributor listing identifies a 38-pin HTSSOP package and analog input with I2C output. TI describes the device as a high-performance, multi-channel, digital-input solution whose flexible architecture suits smoke-alarm systems where precision and power consumption are critical. What is a smoke-alarm analog front end? An AFE is a semiconductor that connects physical sensing elements to an embedded system. In a photoelectric alarm, light scattering and light-absorption signals require controlled excitation, amplification, filtering, and diagnosis. The TPS8802DCPR integrates those signal-chain functions together with supporting regulators and drivers, reducing the number of discrete components and helping designers create a compact, low-power detector platform. The verified TI product information highlights a wide input-voltage range, low standby-power consumption, and power-saving features designed to support 10-year battery-powered smoke-alarm systems. Its dual-wave photoelectric architecture and CO-detection capability allow one integrated platform to combine optical smoke sensing with electrochemical CO-sensor signal conditioning. The I2C interface provides a digital control and diagnostic path, while the analog input supports direct connection to sensing circuitry. The TPS8802DCPR is intended for residential smoke alarms, combination smoke-and-CO alarms, and other safety products requiring highly integrated sensing support. Its integrated regulators and amplifiers can simplify power-tree design compared with a discrete implementation, while digital configuration can support manufacturing tests and field diagnostics. Exact electrical limits, gain settings, timing values, and pin functions were not included in the supplied verified records and therefore require confirmation from the manufacturer datasheet before design release. For battery operation, standby current is especially important because the target application is a long-lived safety device. Designers should calculate average and peak current across the sensing duty cycle, confirm regulator startup behavior, and verify that low-power modes preserve alarm thresholds and diagnostic performance. The I2C pull-up arrangement, grounding, and decoupling should follow the manufacturer layout guidance to prevent communication errors or unintended current consumption. This product page consolidates the verified distributor classification, manufacturer application description, package information, source links, and design cautions. It does not invent electrical parameters or claim unverified drop-in equivalents. Confirm the complete pinout, absolute maximum ratings, recommended operating conditions, and lifecycle status in the current Texas Instruments documentation before schematic capture or PCB release.

TPS8804DCPR

TPS8804DCPR - Analog Front End for Commercial Smoke Detector | Texas Instruments

The Texas Instruments TPS8804DCPR is an integrated analog front end (AFE) and system power management IC for commercial smoke detectors. Housed in a 38-pin HTSSOP (DCP) package, it integrates multiple functions including photoelectric chamber driver circuitry, a piezo buzzer driver, an I2C communication interface, and a low-dropout (LDO) regulator chain to support battery-powered smoke alarm designs. A smoke detector AFE is a specialized analog front end that combines the bias and signal-conditioning paths used by optical or ionization smoke sensors with the housekeeping functions needed to run a battery-powered alarm. The TPS8804DCPR falls within the broader family of sensor and detector interface ICs that sit between the physical sensor element (photodiode or ionization chamber) and the system microcontroller or horns driver. Its role is to power, bias, read, and test the sensor while managing battery life, supervisory housekeeping, and interconnect functions across multi-unit networked installations. Key features include analog signal paths for both photoelectric and ionization smoke sensor types, an integrated boost converter for high-current piezo buzzer drive, an integrated LDO chain for system rails, an I2C interface for configuration and status readback, an interconnect driver for interlinking multiple smoke alarm units in a building, and on-chip timers for sensor self-test. The IC is intended for use with an external MCU that runs the smoke detection firmware. Operating voltage is designed to support common 9V battery and regulated mains-powered topologies. The TPS8804DCPR is optimized for ultra-low standby current so the detector can sit on a battery for years without replacement, while still providing rapid sensor biasing and high-current piezo drive during an alarm event. Its integrated boost converter eliminates the need for a discrete driver MOSFET and inductor for the buzzer, reducing BOM count. The HTSSOP-38 package provides adequate thermal dissipation for the piezo boost stage at typical alarm sound pressure levels. Typical applications include residential and commercial smoke alarms, CO-and-smoke combination detectors, heat detectors with piezo alarms, and industrial safety notification appliances. The interconnect feature lets installers link multiple units so that all alarms sound when any one unit triggers, a key requirement for multi-room buildings. When designing with this part, follow the reference layout in the TPS8804 datasheet for the boost inductor and feedback loop. Use low-leakage ceramic capacitors on the photo-sensor input to preserve low standby current and accurate chamber biasing.

TRS3221EIDBR - 3-5.5V RS-232 Transceiver, ±15kV ESD | Texas Instruments

The Texas Instruments TRS3221EIDBR is a 3-V to 5.5-V single-channel RS-232 line driver/receiver with ±15-kV IEC-ESD protection, packaged in a 16-pin SSOP (DB). It operates from a single supply rail and integrates a charge-pump that generates the ±RS-232 voltage swing from the input supply, so no external ±12 V rails are required. The device supports data rates up to 250 kbps and is rated for ±15-kV HBM, ±8-kV IEC 61000-4-2 contact, and ±15-kV IEC 61000-4-2 air-gap ESD strikes on the RS-232 bus pins. An RS-232 transceiver is a type of line driver/receiver IC that converts logic-level (typically 0/3.3 V or 0/5 V CMOS/CMOS) UART signals into the ±5 V to ±15 V voltage swings required by the TIA/EIA-232-F and ITU v.28 standards. It belongs to the broader interface-IC category, sitting between the UART block of a microcontroller/SoC and a DB-9 (or equivalent) connector on the serial port. Single-channel variants like the TRS3221E serve compact, point-to-point designs where two driver/receiver channels are not needed, helping shrink BOM cost and PCB area versus 2-channel parts. Key features include 1 driver and 1 receiver per channel, a dedicated enable input for power management, an auto-powerdown mode that drops quiescent current to 1 µA typical when the cable is disconnected, and an always-active supplementary receiver that monitors the ring-indicator path even in shutdown. The device meets or exceeds the TIA/EIA-232-F and ITU v.28 electrical specifications, and is offered in industrial temperature grades of -40 °C to +85 °C. A high-speed pin-compatible upgrade, the TRSF3221E, is available where 1 Mbit/s operation is required. The TRS3221E uses an on-chip switched-capacitor voltage converter with four external 0.1 µF charge-pump capacitors. The architecture tolerates supply rails as low as 3.0 V while still generating compliant ±5 V (minimum) RS-232 output swings, which is the headline advantage over legacy 5-V-only RS-232 transceivers. Drivers are slew-rate limited to keep EMI low, and the receivers include hysteresis to reject noise on long cables. Typical applications include industrial single-port serial ports, point-of-sale terminals, handheld data collectors, factory automation equipment, medical instruments with DB-9 serial interfaces, and any embedded system that needs a robust RS-232 link from a 3.3 V or 5 V UART. Designers often pair this part with a TVS array for additional surge protection when the cable is exposed to outdoor or industrial transients. When designing with the TRS3221EIDBR, place the four charge-pump capacitors (typically 0.1 µF X7R) as close as possible to the C0+, C0-, C1+, C1- pins to minimize supply ripple. Decouple VCC with a 0.1 µF + 1 µF combination near the pin, and respect the absolute-maximum ratings on the RS-232 outputs (typically ±13.2 V) by avoiding back-drive when the IC is unpowered.

TRS3221EIRGTR

TRS3221EIRGTR - 3-5.5V RS-232 Transceiver, 250kbps, ±15kV ESD | Texas Instruments

The Texas Instruments TRS3221EIRGTR is a 3- to 5.5-V single-channel RS-232 line driver/receiver delivering 250 kbps data rate with ±15 kV IEC-ESD protection in a 16-pin VQFN (RGT) package measuring 3x3 mm with an exposed thermal pad. The device integrates one driver and one receiver, supports VCC operation from 3.0 V to 5.5 V (compatible with TTL/CMOS logic levels), and meets or exceeds the requirements of TIA/EIA-232-F and ITU v.28 standards. An RS-232 transceiver is a charge-pump-based interface IC that translates between TTL/CMOS logic levels (0-3.3 V or 0-5 V) and the ±5 V to ±15 V swing required by the legacy TIA/EIA-232-F serial communication standard. RS-232 transceivers belong to the broader interface IC family, which sits hierarchically between discrete level-shifters and protocol controllers (UARTs) in wired communication systems. RS-232 remains widely deployed in industrial equipment, point-of-sale terminals, medical instruments, and embedded debug ports where simplicity, point-to-point connectivity, and proven robustness outweigh the bandwidth advantages of USB or Ethernet. Key features include ±15 kV Human-Body Model (HBM) ESD protection on RS-232 pins, ±8 kV IEC 61000-4-2 contact discharge, ±15 kV IEC 61000-4-2 air-gap discharge, and an automatic powerdown feature that disables drivers when no valid RS-232 cable is detected. The on-chip dual charge pump requires only four external 0.1 µF capacitors, enabling true 5 V operation from a single 3.3 V supply without a separate ±12 V rail. The 250 kbps data rate is adequate for all standard RS-232 baud rates up to and beyond 115200 with margin to spare. The architecture combines a regulated switched-capacitor voltage doubler/inverter with a proprietary low-dropout RS-232 driver stage and a precision hysteresis receiver. ESD protection is implemented at the cable-side pins using TI's integrated silicon-controlled-rectifier (SCR) clamps. The 16-pin VQFN package's exposed pad provides a low thermal resistance path, which is useful when the part operates near the upper end of its 1 mA quiescent current budget in warm enclosures. Typical applications include industrial PLC programming ports, point-of-sale (POS) terminals, medical device serial consoles, battery-powered handhelds, and embedded debug UARTs that need robust ESD performance in the field. The TRS3221EIRGTR's small 3x3 mm footprint suits space-constrained designs such as USB-to-serial dongles, IoT gateways, and barcode scanners. When designing with this part, place the four charge-pump capacitors as close as possible to the C1+ / C1- / C2+ / C2- pins and keep the RS-232 trace lengths short to maximize ESD margin. Note that the TRSF3221E is the higher-speed (1 Mbit/s) pin-compatible alternative if 250 kbps is insufficient.

TRSF3222CPW - 3V-5.5V RS-232 Transceiver, 2/2 Drivers | TI TSSOP-20

The Texas Instruments TRSF3222CPW is a 2-driver/2-receiver RS-232 line transceiver that operates from a single 3.0V to 5.5V supply in a 20-pin TSSOP package. It supports data rates up to 1 Mbit/s and accepts 5-V logic inputs when powered from a 3.3V rail, making it ideal for mixed-voltage system designs. A line transceiver is an interface device that bridges a logic-level UART (universal asynchronous receiver/transmitter) on a host microcontroller with the RS-232 standard, which swings between +12V and -12V on the bus side. It sits within the Interface IC hierarchy (RS-232 transceiver -> line transceiver -> interface IC -> integrated circuit) and converts TTL/CMOS logic levels to TIA/EIA-232-F compliant voltage levels while protecting the host from ESD events on the cable side. The TRSF3222CPW integrates a dual charge-pump that generates the required +5.5V and -5.5V rails from a single 3.3V supply using four small 0.1 uF external capacitors. Standby current is typically 1 uA, supporting low-power portable designs. The receivers remain active in shutdown, allowing wake-up characters to be detected without waking the host. ESD protection exceeds +/-15 kV HBM on the bus pins. Typical applications include industrial point-of-sale terminals, factory automation equipment, portable diagnostic instruments, and battery-powered barcode scanners where 3.3V logic must communicate with legacy RS-232 peripherals. The wide 3.0V-5.5V supply range also makes the part suitable for USB-to-serial bridges and embedded computing modules. When designing with this device, place the four charge-pump capacitors as close to the IC as possible to minimize loop inductance. The TSSOP-20 footprint requires standard surface-mount assembly with a maximum reflow temperature per JEDEC J-STD-020. Decouple VCC with a 0.1 uF ceramic plus a bulk tantalum if the supply impedance is high.

TS321ID

TS321ID - Single 30 V 800 kHz Op Amp | Texas Instruments

Texas Instruments TS321ID is a single bipolar operational amplifier rated for 30 V operation, an 800 kHz gain-bandwidth product, and an 8-pin SOIC package. It is intended for cost-sensitive applications where space savings matter, making it a compact general-purpose amplifier for industrial, instrumentation, and signal-conditioning systems. An operational amplifier is an analog integrated circuit that uses high open-loop gain to amplify the difference between two input voltages. The TS321 belongs to the broader hierarchy of operational amplifier, analog amplifier, signal-conditioning IC, and semiconductor. Its basic amplifier functions include voltage amplification, buffering, filtering, summing, and feedback-based control, provided the external feedback network and operating limits are respected. The verified product information identifies a single amplifier circuit, a 30 V maximum operating framework, 800 kHz bandwidth, general-purpose classification, and an 8-pin SOIC package. The bipolar architecture and low-power positioning suit cost-sensitive designs, while the SOIC footprint supports conventional surface-mount assembly. Exact offset, bias-current, noise, slew-rate, common-mode, and output-swing values require confirmation in the manufacturer datasheet before final circuit sign-off. TS321ID is useful as a general-purpose amplifier in low- and moderate-bandwidth analog paths. Its verified 800 kHz bandwidth makes it relevant to signal conditioning where the required closed-loop bandwidth is well below that level. The single-amplifier configuration can simplify designs that need one amplifier rather than a dual package, particularly in sensor interfaces, control loops, audio preamplification, and industrial measurement circuits. The principal design consideration is preserving signal headroom and stability. An 8-pin SOIC package requires adequate PCB spacing, controlled grounding, and decoupling close to the power pins. Feedback resistors, compensation components, and input or output loading determine the actual usable bandwidth and must be evaluated against the application. Because verified operating details beyond the supplied values are incomplete, engineers should consult the TS321 manufacturer datasheet before choosing component values. This page combines verified manufacturer and distributor information, structured technical context, sourcing guidance, and engineering notes. It also clearly identifies unavailable electrical parameters rather than presenting guessed values, helping engineers move from part selection to a validated TS321ID design with fewer sourcing and specification ambiguities.

TS339CD

TS339CD - Micropower Quad CMOS Comparator | STMicroelectronics

STMicroelectronics TS339CD is a micropower quad CMOS voltage comparator containing four independent general-purpose comparators in a 14-pin SOIC package. Each comparator features open-drain CMOS outputs, extremely low input bias current, and a typical supply current consumption of 9 µA per comparator. The device provides a typical response time of 1.5 µs for a 5 mV input overdrive. A voltage comparator is an analog integrated circuit that compares two input voltages and produces a digital logic result indicating which input is higher. The TS339 belongs to the broader comparator hierarchy, where a quad comparator integrates four independent analog-to-digital decision channels. Its CMOS construction combines low power consumption with high input impedance, making it suitable for battery-operated sensing, control, and signal-conditioning systems. The four channels can compare sensor outputs with adjustable references or supervise multiple operating conditions. Key characteristics include extremely low input bias current, a typical input offset current of 1 pA, and a typical input impedance of 10^12 ohms. The open-drain outputs allow the device to interface with pull-up resistors, level shifters, wired logic buses, and mixed-voltage systems. A typical response time of 1.5 µs for 5 mV overdrive supports applications requiring fast threshold decisions without the higher supply consumption commonly associated with bipolar comparator families. The TS339 is also described as pin-to-pin and functionally compatible with the bipolar LM339 family. This compatibility makes the open-drain architecture particularly useful when an existing board uses pull-up-based logic. Each comparator can independently monitor a sensor threshold, supply rail, window comparator, or control signal. Because the outputs are open drain, multiple device outputs can share a common pull-up when the system designer confirms that the combined sink-current and timing requirements remain acceptable. Typical uses include low-power battery monitoring, industrial threshold detection, sensor interface conditioning, overvoltage protection, and embedded control systems. The 14-pin SOIC package supports conventional surface-mount assembly and provides one channel per comparator, making channel assignment straightforward in multi-parameter monitoring systems. When laying out the circuit, route the comparator inputs away from switching nodes and place the open-drain pull-up resistors close to the output pins. Confirm input common-mode limits, supply-voltage range, output sink-current capability, and the effect of external pull-up resistance before using the device in a new design.

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.

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.

The TS339IN includes four general-purpose comparator channels with CMOS, open-drain outputs. 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.

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. These characteristics reduce disturbance from high-impedance sensors and make the device suitable for monitoring systems where the source impedance could otherwise create input-related errors. Its differential CMOS architecture supports single-supply or dual-supply operation. The wide single-supply range extends from 1.5 V to 8 V, while the dual-supply capability covers positive and negative sensing ranges. The open-drain outputs require an external pull-up resistor when the output must rise to a positive logic voltage. This configuration provides flexible bus-level interfacing and permits wired-AND behavior when multiple outputs share a pull-up node. Typical uses include battery-powered threshold detection, sensor signal conditioning, window monitoring, overvoltage and undervoltage detection, and low-speed control loops. The 600 ns response time is appropriate for power-management, industrial-control, and instrumentation systems that require a rapid decision without the higher energy consumption of a high-speed comparator. Design the pull-up network around the required logic level, output rise time, and total capacitance. Place the pull-up resistor close to the output net, keep comparator input traces away from switching nodes, and account for input bias current when driving very high source impedances.

The STMicroelectronics TS372CN is a low-power dual CMOS voltage comparator with two independent comparison channels, a 1.5 V to 8 V single-supply operating range, support for dual supplies up to ±8 V, and an 8-DIP package. 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. This page organizes the key electrical characteristics, commercial information, package details, application guidance, and available cross-reference information for engineers evaluating the TS372CN.

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.

TS372IN

TS372IN - Dual CMOS Voltage Comparator, 8-DIP | STMicroelectronics

The STMicroelectronics TS372IN is a low-power dual CMOS voltage comparator containing two independent precision comparators, with a 600 ns response time and a maximum input offset voltage of 12 mV. Housed in an 8-pin through-hole DIP package, it accepts single supplies from 3 V to 16 V or dual supplies from ±1.5 V to ±8 V. Each comparator consumes approximately 0.1 mA, making the device suitable for low-power signal-conditioning systems. A voltage comparator is an analog mixed-signal semiconductor that compares two input voltages and produces a digital-level indication of their relationship. The TS372IN belongs to the comparator hierarchy and uses CMOS input stages with open-drain outputs, allowing its outputs to support TTL-compatible interfacing. Two independent comparator channels in one package reduce component count when a system needs two sensing or threshold decisions. Key features include independent comparator operation, low supply current of 0.1 mA per comparator, and operation from either a single or dual supply. The single-supply range of 3 V to 16 V supports industrial logic systems, while the ±1.5 V to ±8 V dual-supply range permits comparison of signals around ground. The open-drain output architecture also enables wired-AND behavior when multiple comparator outputs share a pull-up resistor. The differential CMOS architecture provides a favorable balance between speed, power consumption, and input behavior. With a response time of 600 ns, the TS372IN is suitable for threshold monitoring, signal crossing detection, and control-loop qualification without the delay of slower micropower comparators. Its two independent channels can monitor separate sensor nodes or provide complementary decisions, although common-mode range and input-bias details should be checked against the manufacturer datasheet for the exact operating conditions. Typical applications include industrial sensor thresholding, battery and power-supply monitoring, overvoltage detection, window comparison in control systems, and low-power logic interfaces. 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. Place the pull-up resistor directly at each open-drain output and confirm that its value produces the intended rise time. Do not permit an output to exceed its supply voltage, and use the DIP footprint without relying on exposed-pad thermal dissipation because the package does not provide one. This product page combines supply-range and timing details with package-level engineering guidance, application analysis, and qualified same-footprint replacement information. It is intended to help engineers select the TS372IN, plan the input and output network, and assess drop-in alternatives without confusing package compatibility with guaranteed functional equivalence.

TS374CD

TS374CD - Low-Power Quad CMOS Comparator | STMicroelectronics

The STMicroelectronics TS374CD is a low-power quad differential CMOS voltage comparator containing four independent precision comparator channels in a 14-pin SOIC package. 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. This product page organizes the TS374CD’s comparator architecture, electrical characteristics, practical applications, verified equivalent information, and design considerations. It also highlights the lifecycle constraint and distinguishes a documented cross-brand alternative from components that may use the same 14-pin footprint but differ in output behavior, supply limits, or logic compatibility.

TS374CN - Quad CMOS Comparator, 3-16 V, 14-DIP | STMicroelectronics

The STMicroelectronics TS374CN is a low-power quad differential voltage comparator with four independent channels, open-drain outputs, and a 14-pin through-hole DIP package. It operates from 3 V to 16 V with a single supply or from ±1.5 V to ±8 V with dual supplies. Key characteristics include a typical response time of 200 ns, typical input impedance of 10^12 ohms, and very low input bias current of 1 pA at 5 V. A voltage comparator is an analog integrated circuit that compares two input voltages and produces a digital logic result indicating which input is higher. Comparators belong to the broader interface IC and signal-conditioning hierarchy, where they convert continuously varying analog signals into logic-compatible decisions. The TS374CN's four independent channels make it useful wherever several threshold or sorting decisions must be performed by one device. The TS374CN provides four low-power precision comparators using a LinCMOS process. 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. The open-drain architecture can also support level translation when the pull-up supply differs from the comparator supply, provided voltage and timing limits are respected. 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. Inputs should remain within the common-mode range, and unused comparator channels should be tied to defined logic levels rather than left floating. This page combines manufacturer-family characteristics, verified distributor packaging information, drop-in replacement guidance, comparison parameters, and practical circuit-design notes to support component selection and PCB implementation.

It provides a typical response time of 200 ns and a typical input impedance of 10^12 ohm, making it suitable for precision threshold, sensing, and signal-conditioning circuits. A voltage comparator is an analog signal-conditioning integrated circuit that compares two input voltages and changes its output state when the difference crosses a defined threshold. The TS374ID belongs to the comparator hierarchy, within analog ICs and signal-conditioning semiconductors.

Key characteristics include four independent differential comparators, low-power CMOS operation, low input offset voltage, a 3 V to 16 V operating range, and open-drain outputs. The open-drain architecture allows each output to be pulled up to the required logic level with an external resistor, which is useful when interfacing the TS374ID to systems operating above or below its supply voltage. The TS374ID uses STMicroelectronics silicon linear MOS technology to achieve its consumption-to-speed balance. Its typical 200 ns response time supports faster threshold decisions than general-purpose slow comparators, while the high typical input impedance reduces loading on the sensed source. Each differential input pair provides a non-inverting and an inverting comparison input, and the output indicates which input is higher. Typical uses include sensor threshold detection, battery and power-supply monitoring, industrial control logic, window comparators, overvoltage detection, and general digital control interfaces. The quad configuration is particularly useful when a board must monitor several independent analog quantities, such as temperature, pressure, current, or supply rails. Designers should use pull-up resistors on all open-drain outputs and confirm that output rise time, input common-mode range, and supply timing meet the system requirements. Care is also needed when several comparators can pull an output low simultaneously, because the shared pull-up resistor must tolerate the combined sink current. This page combines the TS374ID electrical characteristics, package details, practical circuit considerations, and package-compatible replacement guidance to support faster component selection, footprint verification, and second-source planning.

A 200 ns typical response time supports faster decision-making in monitoring and control circuits, while the open-drain output architecture permits wired logic, pull-up integration, and multi-node signal combinations. The STMicroelectronics silicon lin MOS process gives the device its low-power operating characteristics and favorable consumption-speed ratio. Each comparator can operate from single or dual supplies, allowing the TS374IN to suit low-voltage logic systems as well as broader analog interfaces.

TS393CD - Dual Micropower Comparator | STMicroelectronics

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. It highlights where the TS393CD differs from related open-drain comparator choices and explains the electrical checks required before approving a substitute in an existing PCB design.

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 - 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.

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.

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.

TS3A27518ERTWR

TS3A27518ERTWR - 6-Ch 2:1 Analog Mux, 240MHz | Texas Instruments

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.
