TPS3701DDCR

TPS3701DDCR - 36V Window Comparator | Texas Instruments

The Texas Instruments TPS3701DDCR is a 36 V window voltage comparator with an internal 400 mV reference, two open-drain outputs, and a 1.8 V to 36 V supply range, packaged in a 6-pin SOT-23-THIN. It monitors overvoltage and undervoltage conditions in industrial, embedded, and power-management systems. The two precision comparators can operate together as a window detector or independently as two voltage monitors, while external resistors set the monitored thresholds. A window comparator is a specialized voltage-monitoring IC that compares an input voltage against programmed upper and lower limits. Unlike a simple power-supply supervisor, this device combines two precision comparators, a low-power 400 mV reference, and separate fault outputs. It belongs to the broader hierarchy of comparator, voltage supervisor, power-management IC, and semiconductor categories. Its open-drain outputs can pull fault lines or enable signals low and may be wired for wired-AND behavior when required by the system architecture. Key features include a wide 1.8 V to 36 V supply operating range, thresholds adjustable down to 400 mV, low typical quiescent current of 7 microamperes, and high threshold accuracy. The outputs, identified as OUTA and OUTB, are rated to 25 V for overvoltage and undervoltage signaling. The monitored voltage is established with external resistor networks, allowing the same device to address different system rails without changing the comparator package. The TPS3701 architecture is useful when a system must distinguish a valid operating window from an unsafe condition. Two open-drain outputs provide separate information for undervoltage and overvoltage events, helping a controller, protection circuit, or system-management block respond without interpreting a single ambiguous fault signal. The internal reference improves repeatability when the monitored rail is divided down to the reference range. Typical applications include industrial control systems, embedded power rails, battery-powered equipment, power-supply sequencing, automotive-style voltage supervision, and general overvoltage or undervoltage protection. The 36 V supply capability is useful for systems whose monitored rails exceed conventional low-voltage logic levels, while the open-drain outputs allow flexible pull-up selection and interface-level adaptation. When designing the circuit, verify the external resistor divider limits, open-drain pull-up voltage, monitored-voltage range, and output timing before connecting the device. The 6-pin SOT-23-THIN package requires careful placement and adequate copper area. Because the outputs are open-drain, each line needs an appropriate pull-up unless it is intentionally connected to another open-drain node. This page combines manufacturer specifications, distributor availability information, application guidance, and verified replacement analysis. It is intended to help engineers identify whether the TPS3701DDCR fits a voltage-window monitoring design and to distinguish genuine same-footprint replacements from parts that only provide similar monitoring functions.

TPS3701DDCT

TPS3701DDCT - 36V Dual Window Comparator | Texas Instruments

The Texas Instruments TPS3701DDCT is a dual window voltage detector with two precision comparators, a 400 mV internal reference, and two open-drain outputs rated to 25 V, packaged in a 6-pin SOT-23-THIN configuration. It operates from 1.8 V to 36 V and is designed for overvoltage and undervoltage monitoring. A window comparator is a voltage detector that checks whether an input voltage lies between programmable upper and lower thresholds. Unlike a general-purpose comparator, this device integrates two comparison channels and a reference, allowing one IC to monitor both rail boundaries. In the power-management hierarchy, it belongs to the comparator and voltage-supervisor family rather than a power-regulator family. Key features include the 1.8 V to 36 V supply range, a 400 mV internal reference, two open-drain outputs, and monitoring flexibility through external resistor networks. The open-drain outputs can be pulled up to an appropriate external voltage, allowing wired interface use and flexible system-level signaling. Reported low quiescent current is approximately 7 µA typical, making the device suitable for low-power monitoring systems. The TPS3701 can operate as a window detector or as two independent voltage monitors. The monitored thresholds are established with external resistors, while the internal reference provides the comparison basis. Its high-voltage operating range allows monitoring of industrial supplies and other rails where input transients or nominal voltages exceed the range of simpler low-voltage supervisors. Response time is reported in distributor data as approximately 155 µs. Typical applications include industrial automation, battery systems, power-supply protection, sensor interfaces, and embedded control systems. It is especially useful when a system must assert separate fault signals when a monitored voltage becomes too high or too low. Because the outputs are open-drain, pull-up resistors are required unless the output is connected directly to a compatible pull-up arrangement. Designers should verify the full datasheet pinout, threshold tolerances, timing, output ratings, and capacitor or resistor recommendations before production. The SOT-23-THIN footprint supports compact layouts, but the open-drain pins and monitor-input network require careful routing. For replacements, compare the complete pinout and threshold architecture rather than selecting a part only by supply voltage or package name. This page combines verified manufacturer information, distributor pricing references, and practical design guidance.

TPS4141-Q1 - 1200V Configurable Divider | Texas Instruments

The Texas Instruments TPS4141-Q1 is a high-voltage precision matched resistor divider with an integrated programmable-gain amplifier (PGA), designed for accurate high-voltage measurement in automotive and industrial applications. The device supports input voltages up to 1200V and provides four configurable divider ratios via the DIV0 and DIV1 inputs. It is available in a 10.30mm × 10.30mm SOIC-11 (DWQ) package, optimized for space-constrained automotive systems. A high-voltage precision resistor divider is a specialized analog front-end IC that scales high-voltage inputs down to a safe range for downstream ADC or microcontroller measurement. It combines matched precision resistors with a PGA to maintain accuracy across temperature and voltage extremes, eliminating the need for discrete resistor networks and trimming. This architecture reduces board area and improves measurement reliability in high-voltage environments. The TPS4141-Q1 integrates a high-voltage switch that connects or disconnects the high-voltage sense pin, providing uni-directional current blocking when disconnected. The programmable-gain amplifier supports four divider ratios using DIV0 and DIV1, enabling flexible measurement scaling for different voltage ranges. External precision reference voltage can be supplied from REF to HVGND for bi-directional voltage measurement, and switching between uni-directional and bi-directional sensing during operation is possible. The device is AEC-Q100 qualified for automotive applications, ensuring robust performance over a wide temperature range. Its high-voltage capability and integrated switch make it suitable for battery management systems, traction inverters, and industrial motor drives where precise voltage monitoring is critical. The integrated PGA and matched resistors provide high accuracy, reducing system calibration overhead. Typical applications include electric vehicle battery pack voltage monitoring, solar inverter DC bus sensing, and industrial 24V/48V system voltage measurement. The high-voltage switch allows the sense line to be disconnected for safety or power saving, while the divider ratios allow the same device to serve multiple voltage ranges. Designers should ensure proper PCB clearance and creepage distances for 1200V operation, and use the external REF for bi-directional measurements when needed.

TPS65193RGER

TPS65193RGER - Dual High-Voltage TFT-LCD Scan Driver | TI

The Texas Instruments TPS65193RGER is a dual high-voltage scan driver for amorphous-silicon-gate TFT LCD panels, providing high-voltage gate-line outputs from -28 V to 35 V in a 24-VQFN 4 mm x 4 mm package. Each scan-driver section accepts a logic-level CPV input and produces complementary CKV and CKVB outputs, while a logic-level STV input generates the high-voltage STVP output. A high-voltage scan driver is a specialized interface IC that transfers low-voltage timing commands from the host controller to the elevated voltages required by TFT gate lines. Its position in the display hierarchy is controller interface, then row-driver interface, then gate-line scan driver. This device does not process image data; instead, it supplies the high-voltage, charge-sharing waveforms that select and bias TFT rows. Key features include a 35 V high output-voltage level, an output swing down to -28 V, scan-driver output charge sharing, and four logic-level inputs. The 24-VQFN package measures 4 mm on each side, supporting compact display-module designs where connector count and board area are constrained. The RGER orderable designation identifies the 4 mm x 4 mm VQFN package configuration. Each high-voltage scan driver receives CPVx and generates two outputs, CKVx and CKVBx. A separate STV logic input produces the STVP output. Charge sharing reduces peak drive demand by transferring charge between the complementary outputs rather than driving each output as an isolated hard switch, helping lower switching loss in the gate-line drive network. Typical applications are amorphous-silicon TFT LCD modules, including small-panel monitors, portable instruments, industrial HMIs, test equipment, and control-system displays. The device is most appropriate where the panel requires negative off-level and positive high-level gate drive but does not require a separate source-driver solution from the same device. Designers must account for the -28 V to 35 V output range, provide suitable bypassing on the high-voltage supply rails, and validate output timing against the target TFT panel. Panel bias requirements, leakage into neighboring rows, and clock-edge placement determine whether the charge-sharing outputs provide adequate settling time. This page consolidates the verified manufacturer and distributor information, separates documented specifications from unavailable data, and provides application guidance and comparison considerations that are not presented as a substitute for the complete Texas Instruments datasheet.

TPS65195YFFR

TPS65195YFFR 8-Channel Display Level Shifter | TI

The Texas Instruments TPS65195YFFR is an 8-channel display power and level-shifting integrated circuit packaged in a 30-pin DSBGA. Distributor records classify the device as a video processing IC and an 8-channel level shifter, placing it within the display-interface and video-signal-conversion segment of integrated-circuit applications. Its defining verified characteristics are the eight-channel architecture, display-oriented level-shifting function, and compact 30-DSBGA package. Detailed electrical ratings, supported logic standards, voltage limits, timing values, and thermal limits were not included in the supplied source material and therefore require confirmation from the manufacturer datasheet before schematic or layout release. A display level shifter is an interface IC that translates signals between voltage domains that use different electrical thresholds. This allows a host processor, graphics engine, or display controller to communicate more reliably with display-panel circuitry when input and output levels are not directly compatible. In the broader semiconductor hierarchy, the TPS65195YFFR belongs to interface ICs and, more specifically, to video interface ICs. Its eight channels allow multiple display-related signals to be handled within one package, reducing the component count compared with discrete translators. The verified distributor listing identifies the part as an 8-channel level shifter in a 30-pin DSBGA. This combination can be valuable in compact display modules where board area is constrained and several voltage-domain crossings are required. The BGA form factor also supports dense routing, although it demands assembly processes capable of handling fine-pitch balls. Package dimensions, ball pitch, exposed-pad details, soldering profiles, and reflow requirements must be taken from the official package drawing rather than inferred from the distributor description. Typical design use is a display controller interface, an LCD panel bias or signal interface, and a compact embedded display module. These uses follow from the verified display power and level-shifting classification; the supplied data does not enumerate supported panel interfaces or timing standards. Engineers should therefore treat the TPS65195YFFR as a display-interface candidate, not as a complete or independently characterized video processor, until channel direction, signal type, voltage ranges, and timing constraints are verified. A key implementation consideration is validating every connected display signal against the manufacturer's absolute-maximum and recommended operating limits. Because no pinout was supplied in the verified results, no pin assignments are asserted here. The official datasheet and land-pattern information must be used to confirm signal direction, supply pins, ground pins, and unused-ball handling before PCB routing begins. This page consolidates the verified distributor identity, package, and sourcing information with a structured engineering workflow for datasheet validation, alternative qualification, and display-interface design. It distinguishes confirmed facts from unavailable parameters rather than filling gaps with guessed electrical values.

TPS65197RUYR

TPS65197RUYR - 8-Channel LCD Level Shifter | Texas Instruments

The Texas Instruments TPS65197RUYR is an 8-channel level-shifter IC for LCD display applications, packaged in a 28-pin WQFN (RUY) package measuring 4 mm by 4 mm. It supports 2-channel and 3-channel charge-sharing methods, normal level-shifting operation, and panel discharge to VGH during shutdown. The device is designed to translate timing-controller logic-level signals into the higher gate-level signals required by gate-in-panel (GIP) LCD panels. TPS65197RUYR belongs to the interface IC and display-driver ecosystem. A level shifter is an interface IC that translates voltage domains while preserving signal timing and logic function. In an LCD system, the timing controller operates at lower logic voltages, while GIP row and column driver circuits may require elevated panel voltages. The TPS65197 provides eight channels for this signal conversion and supports panel-specific charge-sharing sequences that help control panel charging and discharge behavior. The principal feature set includes eight level-shifting channels, support for no-charge-sharing, 2-channel charge-sharing, and 3-channel charge-sharing operation, and a dedicated panel-discharge function. The manufacturer product page identifies the device as an 8-channel level-shifter supporting 2-channel and 3-channel charge-sharing and panel discharge in the WQFN (RUY) package with 28 pins. Because GIP panels can accumulate charge and generate transient loads during startup, the charge-sharing architecture is important. The supported operating modes let a system select a charging strategy according to panel timing requirements rather than using a simple fixed level translation approach. The shutdown discharge path provides a defined mechanism for returning panel nodes toward VGH during power-down. Typical uses include notebook computer LCD panels, desktop monitors, television panels, and other GIP-based display systems. The device is most appropriate when the source logic levels, panel gate-drive levels, supported charge-sharing sequence, and shutdown behavior must all be evaluated together. A replacement should not be selected solely by channel count; the timing of each output, panel discharge behavior, voltage ratings, and board footprint must be confirmed against the original design. This page combines the verified manufacturer description, distributor package information, drop-in alternatives, and engineering-oriented design guidance. The 28-pin WQFN footprint, exposed thermal pad, high-speed panel signals, and power-sequencing requirements should be reviewed against the complete manufacturer datasheet before layout or replacement qualification.

TPS65198RUYR

TPS65198RUYR - 13-Channel LCD Level Shifter | Texas Instruments

The Texas Instruments TPS65198RUYR is a 13-channel level shifter with an integrated operational amplifier for LCD televisions and monitors, supplied in a 28-pin WQFN (RUY) package measuring 4 x 4 mm. It supports an operating temperature range of -40 C to +85 C and is designed for display-interface applications where multiple voltage domains and signal buffering are required. A level shifter is an interface IC that translates logic signals between voltage domains whose high and low thresholds differ. In an LCD television or monitor, source electronics, timing controllers, panel interfaces, and backlight systems may operate from different supply rails. A multi-channel level shifter allows those signals to cross between incompatible voltage domains, while the integrated operational amplifier provides buffering for a signal that requires drive or amplification. The TPS65198RUYR's 13-channel architecture consolidates multiple translated logic connections in one package. This can reduce the number of discrete level-shifter components and simplify printed-circuit-board layout compared with a collection of individual translators. Its 4 x 4 mm WQFN format also supports compact display-control designs where connector density and panel-interface routing leave limited board area. The verified operating temperature range is -40 C to +85 C, covering industrial temperature conditions commonly encountered in display electronics. The available LCSC listing identifies an 8 V to 20 V supply-related value, but the provided source excerpt does not clearly identify that parameter or its test conditions; consequently, voltage limits, channel direction, translation thresholds, and the integrated amplifier's electrical ratings require confirmation in the manufacturer datasheet before design release. Typical uses include LCD monitor panel-interface circuits, television timing and control boards, display power-sequence logic, and other multi-rail display systems where a compact level-translation stage is needed. Because this device combines translation and amplification, it can simplify signal-interface design when the source impedance and loading requirements of the translated channels differ. Engineers should confirm every channel's direction, voltage domain, enable behavior, and the exposed-pad connection directly against the TI datasheet and the PCB footprint. The 28-pin WQFN package is also thermally and assembly sensitive; proper land-pattern compliance, paste control, and exposed-pad soldering are required for reliable production yield. This page consolidates the verified manufacturer identification, distributor package data, temperature rating, and supply-range excerpt for TPS65198RUYR, while clearly separating missing electrical data from confirmed values. It also documents the absence of a manufacturer-verified drop-in substitute rather than presenting an unverified package conversion as a drop-in replacement.

TPS65198RUYT

TPS65198RUYT - 13-Channel Level Shifter | Texas Instruments

The Texas Instruments TPS65198RUYT is a 13-channel level shifter with an integrated operational amplifier for GIP-based LCD television and monitor applications, packaged in a 28-pin WQFN (RUY) 4 x 4 mm package. It accepts five timing-controller input signals, uses an internal state machine to generate twelve output signals, and combines level shifting with op-amp signal conditioning. Its specified operating-temperature range is -40°C to +85°C. A level shifter is an interface device that translates logic-voltage levels so circuits using different voltage domains can communicate reliably. In this application, the TPS65198 belongs to the display-driver interface hierarchy: logic level translation, display timing-interface conversion, voltage-domain interfacing, and display-driver ICs. Its integrated op amp provides an additional analog signal-conditioning function alongside the digital level-shift outputs. The principal feature is the combination of a 13-channel level-shifting architecture, five external inputs, twelve internally generated outputs, and op-amp integration. This consolidation can simplify the circuitry associated with GIP panel timing control. The built-in state machine sequences the generated outputs according to the panel-interface requirements, while the integrated amplifier can support signal conditioning where the timing interface requires amplification or level adjustment. TPS65198RUYT is intended for LCD TVs and monitors using GIP technology, where multiple panel signals must be shifted between source-driver, gate-driver, and timing-controller voltage domains. The 4 x 4 mm WQFN package supports compact display-controller boards, but its exposed thermal-pad construction requires careful PCB layout for electrical return paths and heat spreading. Designers should also account for the high-speed edge behavior of the interface when routing signals and selecting input and output impedance. Typical uses include large-panel LCD television timing control, LCD monitor panel interfaces, and other GIP display systems that require coordinated multi-channel level translation. Because the verified source set identifies a 28-pin WQFN package and a -40°C to +85°C range, the device is appropriate for industrial and consumer display environments requiring operation across that temperature span. The principal design consideration is to follow the manufacturer datasheet exactly for exposed-pad connection, decoupling, signal routing, and output-state sequencing. Place input and output return paths close to the device, provide the specified supply and bypass capacitance, and avoid introducing stubs on timing signals. Verify every panel connector voltage domain and the state-machine timing before releasing a display board. This page consolidates the verified manufacturer and distributor information, distinguishes a true drop-in replacement from a packaging-only ordering variant, and highlights application-specific design considerations that are not apparent from a basic distributor listing.

TPS66021YBGR

TPS66021YBGR - 20V Sink, 5V Source USB-C Switch | TI

The Texas Instruments TPS66021YBGR is a one-channel integrated USB-C Power Delivery source-and-sink power multiplexer with a 20V sink path, a 5V source path, and a 5V dead-battery VBUS LDO, housed in a 28-ball DSBGA package measuring 1.61 mm by 2.81 mm. It combines two directional power paths in a compact device intended to manage charging, powering, and protection around a USB-C connection. A USB-C power-path multiplexer is a specialized power-management integrated circuit that controls current between a connector and internal supply rails. It belongs to the hierarchy power multiplexer, power-path controller, power-management IC, and semiconductor. By combining source and sink switching, it can route external VBUS power into a system, provide regulated 5V power from an internal source, and isolate paths during faults or operating-mode changes. The verified manufacturer data identifies a 4V-to-22V sink power path and a 5V source path. The source path enters constant-current operation when its load exceeds the selected current-limit threshold. Each path includes overtemperature and reverse-current protection, while the family supports a fault indication for overcurrent and overtemperature events. The integrated high-voltage VBUS LDO provides 5V for this device and other system components under dead-battery conditions. The TPS66021 integrates a 20V USB-C sink capability and 5V source capability rather than acting only as a passive analog switch. Its VBUS-side architecture allows the system to distinguish and control external power conditions, while the source path supplies a defined output level. The fault function gives the host circuitry a signal when protection circuitry has detected an abnormal event, enabling controlled shutdown or fault recovery. Typical uses include USB-C laptop and tablet power adapters, portable equipment, battery-powered industrial products, and compact systems that must accept external USB-C power while retaining a safe internal 5V supply. The integrated source, sink, and dead-battery functions can reduce board area compared with a discrete switch network. Designers must still validate connector orientation, CC behavior, capacitor selection, current limits, thermal performance, and system power sequencing against the full manufacturer documentation. For PCB layout, follow the manufacturer package land pattern and place high-current input, output, and ground connections with short, wide paths. Place required input and output capacitors close to their associated balls and keep sensitive control and fault traces away from high-di/dt power loops. Verify the selected current threshold, startup behavior, and fault response in the final USB-C system. This page consolidates verified manufacturer descriptions, distributor availability, package information, replacement evidence, and application guidance. It also distinguishes confirmed facts from parameters that require the complete datasheet, preventing unsupported electrical or compliance assumptions during design review.

TPS8802DCPR

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.

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

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.

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

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. This page combines the manufacturer's functional description, package information, comparator performance characteristics, verified cross-reference candidates, and practical design guidance to support component selection, schematic review, and PCB implementation.

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.

TS339ID

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 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. 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.

Each comparator provides CMOS, MOS, or TTL-compatible open-drain output operation for interfacing with mixed logic systems. 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. 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.

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.

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.

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.
