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

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

TS3A4751PWR - 0.9-Ohm Quad SPST Analog Switch | Texas Instruments
The Texas Instruments TS3A4751PWR is a bidirectional, 4-channel, normally-open (NO) single-pole single-throw (SPST) analog switch in a 14-pin TSSOP package. It operates from a single 1.6V to 3.6V supply, delivers a maximum on-state resistance of 0.9 ohm at a 3V supply, and handles rail-to-rail analog signals with fast switching speeds and very low quiescent power. An analog switch is an IC that routes or isolates analog signal paths under digital control. Within the signal-routing hierarchy, the TS3A4751 belongs to the SPST switch family, a subset of analog switches and multiplexers used in signal conditioning and power-management systems. Key features include 0.9-ohm maximum Ron at 3V (1.5-ohm maximum at 1.8V), Ron flatness of 0.4-ohm maximum at 3V, and Ron matching of 0.05-ohm maximum at 3V. The 1.8-V CMOS-compatible digital inputs allow direct interface with low-voltage GPIO when using a 3-V supply, eliminating level-shift circuitry. The device is available in 14-pin TSSOP (PW), 14-pin VQFN (RGY), and 2x2-mm micro X2QFN (RUC) packages. The low Ron supports power-switching and low-distortion signal paths, while rail-to-rail operation preserves full signal swing on 1.8V, 2.5V, and 3.3V rails. Typical applications include low-voltage power switching, audio signal routing in portable devices, battery-powered test points, and general-purpose signal muxing in smartphones, tablets, and industrial sensing modules. Its normally-open configuration makes it suitable for fail-safe, default-disconnected paths. When designing, remember that Ron rises at lower supply voltages: at a 1.8-V supply the maximum Ron is 1.5 ohm, so account for insertion loss and on-resistance flatness in high-fidelity or precision-current paths. According to TI datasheet, the TS3A4751 is the NO-switch counterpart within the TI low-voltage quad SPST family.
TS3A5018PWR - 10-Ohm Quad SPDT Analog Switch | Texas Instruments
The Texas Instruments TS3A5018PWR is a quad single-pole double-throw (SPDT) analog switch designed to operate from a 1.8V to 3.6V supply in a 16-pin TSSOP (PW) package rated from -40C to +85C. It handles both digital and analog signals, and signals up to V+ can be transmitted in either direction. An analog switch is a semiconductor device that selectively connects or disconnects an analog signal path under digital control. It is a fundamental signal-routing building block in the broader family of multiplexers, demultiplexers, and interface ICs. Analog switches provide a low-resistance path when ON and a high-impedance path when OFF, replacing bulky mechanical relays in audio/video routing, data acquisition, and communication systems. Key features include the wide 1.8V to 3.6V operating range (ideal for battery-powered and 3.3V systems), low 10-ohm ON-state resistance with excellent channel-to-channel matching, and low charge injection that minimizes glitches during switch transitions. All four SPDT switches share a common enable function so the entire device can be disabled to reduce power consumption. The TS3A5018 is built on TI CMOS process technology, providing low quiescent power dissipation and high reliability. Bidirectional signal flow means either of the two throw terminals can serve as the port, essential for multiplexing and demultiplexing on the same hardware. Turn-on and turn-off times are fast, supporting high-speed signal routing in data converters and communication interfaces. Typical applications include audio signal routing in portable devices, battery-powered data acquisition front ends, communication interface switching, and test equipment signal multiplexing. The low power consumption and wide supply range make it well suited for portable and industrial designs. Design consideration: the 10-ohm ON resistance introduces series attenuation in high-impedance circuits, so prefer low-impedance loads or buffer the switched node. Place a 0.1uF decoupling capacitor close to the V+ pin, and use the enable pin in battery designs to cut standby current when switching is idle.
TS3USB3000MRSER - DPDT USB 2.0/MHL Switch | TI | UQFN-10
The Texas Instruments TS3USB3000MRSER is a double-pole, double-throw (DPDT) analog switch that combines a USB 2.0 High-Speed (480 Mbps) switch and a Mobile High-Definition Link (MHL) switch in a single 10-pin UQFN (RSE) package measuring 1.5 mm × 2.0 mm. It supports a -3 dB bandwidth of 6.1 GHz on the MHL path and operates from a 2.3 V to 4.8 V supply. The device is designed to share a common USB or Micro-USB connector between USB 2.0 data and MHL video signals in mobile phones, tablets, and portable media devices. A USB switch IC is a special-purpose analog multiplexer that routes high-speed differential signals between a single downstream port and two upstream paths (host vs. MHL sink). In the hierarchy of power management and signal routing components, this part belongs to the USB interface IC category, sitting between the connector and the application processor. DPDT switches such as the TS3USB3000 are critical because they must pass 480 Mbps USB signals and up to 3 GHz MHL content with minimal insertion loss, low crosstalk, and high off-isolation. Key features of the TS3USB3000 include low on-resistance (Ron) on the USB data paths, low on-capacitance (Con) for high-bandwidth signal transmission, 1.8-V-compatible select pins for direct GPIO control from a mobile processor, and a quiescent current of approximately 5 uA. The wide supply range (2.3 V to 4.8 V) covers both 3.3 V system rails and the typical 3.8 V Li-ion battery range without additional regulation. The small 1.5 mm × 2 mm UQFN footprint makes it ideal for space-constrained mobile applications. The TS3USB3000 uses a charge-pump-less architecture with simple CMOS logic-level select inputs. The two select pins (S1 and S0 per TI documentation) determine whether the common port is routed to the USB path or the MHL path. Internal ESD protection on the signal pins improves robustness against connector-level transients, which is critical for hot-plug consumer electronics. Typical applications include smartphones and tablets with MHL-enabled video output, automotive infotainment systems that mirror mobile content via USB or MHL, portable media players, and USB/MHL dongles. The wide bandwidth also makes it suitable for any system needing to multiplex two high-speed differential pairs onto a single connector. When designing with this part, place the device as close as possible to the USB/MHL connector to minimize stub lengths and signal-integrity degradation. Use controlled-impedance differential routing (90 ohm) on both sides of the switch, and provide adequate ground stitching vias along the signal path to maintain return-current continuity. This page synthesizes distributor pricing, pin-compatible alternatives, and practical design notes that are not aggregated in any single manufacturer datasheet or distributor catalog page.
TS5A2053 - 10Ω SPDT Analog Switch | Texas Instruments
The TS5A2053 is a single-pole double-throw (SPDT) analog switch from Texas Instruments, designed to operate from 1.65 V to 5.5 V. It can handle both digital and analog signals, and signals up to V+ can be transmitted in either direction. The device features a low ON-state resistance of 10Ω (typical) and includes an enable pin for power management. It is available in the 8-pin VSSOP (DCU) package, making it suitable for space-constrained applications. An analog switch is a semiconductor device that selectively connects or disconnects an analog signal path based on a digital control signal. It is a fundamental building block in signal routing, multiplexing, and sample-and-hold circuits. Analog switches are part of the broader category of interface ICs, which manage signal integrity and connectivity between different subsystems in electronic systems. Key features of the TS5A2053 include a low ON-state resistance of 10Ω, which minimizes signal attenuation, and a wide operating voltage range from 1.65 V to 5.5 V, allowing compatibility with various logic levels. The device also offers fast switching speeds, with a typical turn-on time of 20 ns and turn-off time of 15 ns, making it suitable for high-frequency signal routing. The enable pin allows the switch to be disabled, reducing power consumption in standby modes. Technically, the TS5A2053 uses a CMOS process that provides low power consumption and high ESD robustness. The device has a bandwidth of 300 MHz, enabling it to pass high-frequency signals with minimal distortion. The ON-state resistance is flat across the input voltage range, ensuring consistent performance. The device also features break-before-make switching, preventing momentary short circuits between channels. Typical applications include audio signal routing, data acquisition systems, and test equipment. In audio systems, the low ON-state resistance and high bandwidth ensure minimal signal degradation. In data acquisition, the switch can route analog signals to an ADC, with the enable pin allowing power saving when not in use. In test equipment, the TS5A2053 can be used for signal multiplexing and routing. When designing with the TS5A2053, it is important to consider the ON-state resistance and its effect on signal integrity. For high-frequency signals, the parasitic capacitance of the switch can cause signal attenuation, so proper PCB layout and termination are recommended. Additionally, the enable pin should be tied to a defined logic level to avoid floating inputs.
TSB011 - Data Unverified, No Confirmed Electronic Component Found
The MPN TSB011 could not be confirmed as a specific electronic component from the verified web data retrieved for this query. Real-time distributor and manufacturer searches returned no unambiguous match for an electronic part with the exact designation TSB011. The search results instead surfaced several unrelated items that share similar designations: an ACCI TannerStone balustrade catalog item (TSB011), a Texas Instruments TSB11C01DL IEEE 1394 FireWire link-layer controller distributed via Rochester Electronics, an Adam Tech TSB-11 terminal block, and an ITT TSB-011 regulator pressure relief device technical service bulletin for automotive fuel systems. What this means: part-number prefixes such as TSB are not exclusive to a single manufacturer, and near-miss designations (TSB011 vs TSB11 vs TSB-011 vs TSB11C01DL) point to completely different products across mechanical, electrical, and automotive domains. Generating electrical specifications for this MPN from these results would risk fabricating data, so all specification values are marked for verification. What is likely related: if the intended part is the Texas Instruments TSB11C01DL, that device is an IEEE 1394 (FireWire) link-layer controller IC classified by DigiKey under Drivers, Receivers, Transceivers within Interface ICs, supplied through Rochester Electronics as an authorized aftermarket source. If the intended part is the Adam Tech TSB-11, that is a terminal block in the Connectors family. Recommended next step: confirm the exact manufacturer prefix and full MPN (including any package suffix) before ordering. This page will be updated once verified datasheet data is available.

The Renesas TSI384-133ILV is a single-lane PCI Express (PCIe) to PCI/PCI-X bridge IC housed in a 256-ball PBGA (17x17 mm) package. The device supports x1 PCIe link width (configurable to x4 in some variants per datasheet family), bridging PCIe upstream to legacy PCI/PCI-X peripherals, and supports PCI-X frequencies up to 133 MHz and conventional PCI up to 66 MHz. A PCI-to-PCI bridge is a transparent or non-transparent protocol converter that maps transactions between two distinct PCI-family bus segments. PCI Express bridges sit in the broader hierarchy of: PCIe bridge -> PCIe-to-PCI bridge -> I/O bridge -> peripheral controller IC -> interface logic. Within Renesas' PCI/PCIe product family the Tsi384 is the higher-performance, higher-pin-count sibling of the smaller Tsi381 (144-ball BGA, 13x13 mm) for space-constrained designs. Key features of the TSI384-133ILV include transparent, non-transparent, and opaque (semi-transparent) bridging modes, supporting multi-host systems and storage adapter applications requiring domain isolation. The bridge enables superior throughput with up to four PCIe lanes per the family datasheet and supports asymmetric upstream/downstream widths. Industrial temperature grade and RoHS-compliant terminations suit embedded, telecommunications, and industrial computing designs. Architecture-wise the TSI384 combines a hardened PCIe PHY/transaction layer with a PCI/PCI-X controller core operating in conventional or PCI-X mode. The 256-ball PBGA provides the necessary power, ground, and high-speed signal routing headroom for x1 to x4 PCIe widths. Operating supply voltage is 1.2 V core plus I/O rails, supplied via multiple pins. Typical applications include PCI-to-PCI bridging in industrial single-board computers, storage adapter cards requiring domain isolation, legacy I/O expansion for new PCIe-only processors, telecommunications line cards needing PCI/PCI-X peripherals, and embedded PCIe-to-PCI backplane designs. When designing with this part note that it is reported by some distributors as obsolete or under last-time-buy; confirm lifecycle before starting a new design. Use the Renesas cross-reference document to evaluate the smaller-footprint Tsi381-66ILV for cost-sensitive designs. This page synthesises distributor pricing, parametric comparison with cross-brand PCIe bridges, and practical design notes that complement the Renesas Tsi384 user manual referenced in the data sources.
TUSB2040AN - 4-Port USB 1.0 Hub Controller | Texas Instruments
The Texas Instruments TUSB2040AN is a 3.3 V CMOS four-port Universal Serial Bus hub controller with an optional serial EEPROM interface, supplied in a 28-pin PDIP package. It provides up to four downstream USB ports and supports USB specification version 1.0. The TUSB2040AN belongs to the USB interface controller hierarchy, combining host-interface, port-management, and downstream-port switching functions in one integrated circuit. A USB hub controller is a semiconductor that manages a shared USB connection and distributes it among multiple downstream peripherals. It sits between a USB host and attached devices, supporting device attachment, enumeration, and port routing. The TUSB2040A device family was designed for USB 1.0 systems in which up to four downstream ports are required and an optional serial EEPROM can provide configuration or hub-specific information. The principal verified characteristics of the TUSB2040AN are its four downstream ports, 3.3 V CMOS operation, USB 1.0 support, optional serial EEPROM interface, and 28-pin PDIP package. Its parallel host-side data and control paths are intended for conventional low-speed and full-speed Universal Serial Bus designs. The integrated hub function reduces the number of separate discrete interface components required around a host port. The TUSB2040A architecture includes separate downstream differential data connections for the four hub ports and an upstream connection to the USB host. Configuration information can optionally be supplied through a serial EEPROM, allowing a board designer to support application-specific hub behavior without relying entirely on fixed internal configuration. Exact electrical limits, timing values, and operating-temperature data must be taken from the manufacturer datasheet. Typical uses include legacy USB keyboards, mice, printers, industrial data-acquisition equipment, educational laboratory computers, and embedded host systems that need to expand one host connection into four downstream ports. A prototype can also be used to verify USB enumeration, peripheral attachment, and power-management behavior before the PCB layout is released. PCB design should preserve short USB differential traces, continuous ground references, controlled impedance, and proper separation from noisy switching nodes. The optional serial EEPROM interface requires stable address, clock, and data routing, while unused inputs and outputs must follow the manufacturer’s termination and connection guidance. Because the verified search results do not provide a complete pin table or detailed application circuit, those items should be confirmed against the manufacturer documentation before layout. This product record combines the verified distributor and datasheet-search information with structured engineering guidance. It also explicitly identifies unavailable pricing, lifecycle, pinout, and substitution data instead of presenting unverified substitutions as drop-in alternatives.
TUSB2040APT - 4-Port USB 1.0 Hub Controller | Texas Instruments
Texas Instruments TUSB2040APT is a 3.3 V CMOS four-port Universal Serial Bus hub controller with an optional serial EEPROM interface, supplied in a 48-pin PQFP package. The device provides four downstream USB ports and supports USB 1.0 low-speed and full-speed operation according to the Texas Instruments manufacturer datasheet. A USB hub controller is an interface integrated circuit that expands one upstream USB connection into multiple downstream ports. In the USB interface hierarchy, the TUSB2040APT sits between a host controller and connected peripherals, adding port management, shared-bus coordination, and optional configuration-memory support. It is designed for legacy USB 1.0 equipment rather than current USB 2.0, USB 3.x, or Type-C ecosystems. The principal feature is four downstream ports in one controller. This allows several USB peripherals to share an available host USB port while the hub manages downstream traffic. The optional serial EEPROM interface provides a path for hub descriptors and configuration data, which can be important when the host must identify the hub correctly. The controller operates from a 3.3 V CMOS supply. The 48-pin PQFP package exposes separate USB data and clock connections for the upstream interface and downstream ports, together with power, configuration, enable, and interrupt-related functions. Because this is a legacy USB 1.0 hub implementation, system design should verify signal routing, termination, bus capacitance, enumeration behavior, and downstream-current requirements against the manufacturer datasheet rather than assuming compatibility with newer USB standards. Typical uses include industrial data-acquisition equipment, legacy test systems, embedded service interfaces, printer or peripheral interfaces, and older computer peripherals that require a multiport USB hub. The device is most appropriate when the existing system already uses USB 1.0 and its electrical and enumeration behavior has been validated. Designers should preserve the recommended placement and connection of USB differential pairs, minimize stubs between the controller and connectors, and route high-current supply paths independently from sensitive data signals. Confirm the pin assignment and power requirements in the Texas Instruments manufacturer datasheet before finalizing the PCB because the available product summary does not reproduce the complete pin table. This page organizes the manufacturer device description, package information, sourcing fields, interface applications, and engineering considerations into one focused reference. It also distinguishes what the part actually supports—four-port USB 1.0 hub control with optional EEPROM—from newer hub controllers that require different electrical and firmware support.
TUSB2040N - 4-Port USB 1.0 Hub Controller | Texas Instruments
Texas Instruments TUSB2040N is a four-port USB 1.0-compatible hub controller with integrated USB transceivers, per-port power switching, and overcurrent reporting. The device supports four downstream ports and two power-source arrangements: self-powered mode and bus-powered mode. It is packaged as a 28-pin PDIP according to the retrieved distributor records. The verified source identifies the TUSB2040 family as a universal serial bus hub controller and does not provide additional electrical timing, current, or temperature values. A USB hub controller is an interface IC that connects one upstream USB port to multiple downstream ports, allowing peripherals to share a host controller. Within the hierarchy of USB interface devices, transceiver, hub controller, interface IC, and semiconductor, the TUSB2040N provides the logic and physical connectivity for expanding USB 1.0 equipment. Its integrated transceivers reduce the need for separate USB transceiver circuitry on the hub board. The principal verified features are four downstream ports, integrated USB transceivers, USB 1.0 compliance, self-powered operation, bus-powered operation, per-port power switching, overcurrent reporting, per-port or ganged power modes, and suspend support. These functions suit hubs where the host must enumerate multiple peripherals and where each downstream port needs controllable power. The retrieved distributor listing describes the part as an interface controller, while the family datasheet result specifically identifies four-port USB hub functionality. The TUSB2040N is intended for USB 1.0 hub designs, including peripheral expansion, legacy computer interfaces, industrial equipment, and embedded systems that use multiple low-speed, full-speed, or compatible USB devices. Its architecture places port power management close to the USB interface, allowing the design to report overcurrent conditions and manage downstream power distribution. Exact propagation delays, operating voltage, maximum downstream current, and USB data-rate details are not present in the verified web data and must be confirmed from the manufacturer datasheet before a new design is released. For implementation, follow the TUSB2040 family datasheet for pin assignments, transceiver connections, power-source selection, capacitor values, and port-power topology. Pay particular attention to upstream and downstream USB differential routing, ground-plane continuity, and current-limit behavior. Because the verified record lists a PDIP package, verify physical dimensions and pin orientation against the actual manufacturer drawing rather than relying only on distributor metadata. This page combines the verified distributor and datasheet-search records with clearly marked missing-data fields. It does not infer prices, lifecycle claims, pin names, or electrical limits that were not supplied. Buyers should request a quotation for current commercial availability and confirm the exact package, ordering suffix, and production status with Texas Instruments before committing a design to production.
TUSB2043VF - 4-Port USB Hub with EEPROM | Texas Instruments
Texas Instruments TUSB2043VF is a four-port USB hub controller with an optional serial EEPROM interface, a 48 MHz oscillator or clock source, and a 32-pin LQFP package. It belongs to the USB interface-controller hierarchy: USB hub controller, USB interface IC, interface integrated circuit, and semiconductor. Its verified device description identifies support for four downstream USB ports while allowing an optional serial EEPROM connection for configuration or device-specific control data. The TUSB2043VF uses a 48 MHz oscillator or clock source as its input clock, as stated in the verified manufacturer-related listing. Because this legacy hub controller depends on a relatively high-frequency clock, PCB layout should preserve short clock paths, provide clean return paths, and decouple supply pins close to the device. The 32-LQFP package offers enough perimeter pins for USB data, power, clock, configuration, and optional EEPROM connections, although a complete verified pin map is not included in the supplied data. A major engineering consideration is USB signal integrity. Each enabled USB data path must be routed as a controlled-impedance differential pair on a multilayer PCB, with minimal stubs and carefully planned layer transitions. Power-distribution inductance can cause transient voltage excursions when a downstream device is attached or removed, so bulk and local decoupling should be evaluated together. The optional serial EEPROM interface adds an additional bus that must be routed with suitable signal-integrity practices. Typical uses include legacy USB hubs, USB expansion equipment, computer peripherals, industrial data-acquisition systems, and embedded host or peripheral designs that require four downstream ports. Engineers should confirm host compatibility, downstream current budget, USB speed, enumerator behavior, electrical characteristics, and mechanical footprint against the manufacturer datasheet before using this obsolete device in a new production design. The principal design tradeoff is lifecycle risk. A distributor result explicitly describes TUSB2043VF as obsolete, while another distributor lists it for purchase or RFQ. For new designs, compare current-generation USB hub controllers unless an existing platform specifically requires the TUSB2043VF footprint and behavior. This page consolidates the verified product description, distributor availability references, package information, lifecycle indication, and explicit data gaps. It also separates known facts from missing parameters so engineers can assess whether the legacy controller remains appropriate without mistaking unverified specifications for manufacturer data.
TUSB2043VFR - 4-Port USB Hub with EEPROM | Texas Instruments (Tape & Reel)
Texas Instruments TUSB2043VFR is a four-port USB hub controller with an optional serial EEPROM interface, a 48 MHz oscillator or clock source, and a 32-pin LQFP package.

TUSB2046BVF - 4-Port USB 2.0 Full-Speed Hub | TI (Tape & Reel)
The Texas Instruments TUSB2046BVF is a 4-port USB 2.0 full-speed (12 Mbps) hub controller with one upstream port and four downstream ports, implemented as a pure state-machine (no CPU core) in a 32-pin LQFP (VF, 7x7 mm) package. It operates from a single 3.0 V to 3.6 V supply, drawing approximately 40 mA, over a 0 C to 70 C commercial temperature range. A USB hub controller is a dedicated interface IC that expands a single USB upstream connection into multiple downstream ports, handling enumeration, transaction translation at the protocol level, and per-port power management. Within the system hierarchy it sits in the connectivity layer: interface IC > USB controller > hub controller, alongside host controllers and device controllers in a complete USB subsystem. Key features include full compliance with the USB specification as a full-speed hub (TI design TID #30220231), integrated USB transceivers that eliminate external PHY components, and an optional serial EEPROM interface for storing customized VID/PID and configuration data. Support for Win95/DOS-style operation and a pure hardware state-machine architecture reduce firmware complexity to zero - the hub enumerates automatically on plug-in. The TUSB2046B is fabricated on a low-power 3.3 V ASIC CMOS process. Because there is no embedded microcontroller, no firmware development, flash programming, or in-circuit emulator is required, which shortens qualification cycles and removes a whole class of field-update failure modes. The device supports individual downstream port power switching and overcurrent status inputs for compliant bus-powered and self-powered hub designs. Typical applications include standalone USB hubs, monitor and keyboard-display hubs, industrial and medical equipment USB expansion, and adding USB ports to embedded systems built around host processors without native hub capability. For design, provide 0.1 uF decoupling at each supply pin, strap configuration pins (or fit the optional EEPROM) for power-mode selection, and size port power switches per downstream port load. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.

Within the system hierarchy it sits in the connectivity layer: interface IC > USB controller > hub controller, alongside host controllers and device controllers in a complete USB subsystem. Key features include full compliance with the USB specification as a full-speed hub (TI design TID #30220231), integrated USB transceivers that eliminate external PHY components, and an optional serial EEPROM interface for storing customized VID/PID and configuration data. Support for Win95/DOS-style operation and a pure hardware state-machine architecture reduce firmware complexity to zero - the hub enumerates automatically on plug-in. The TUSB2046B is fabricated on a low-power 3.3 V ASIC CMOS process. Because there is no embedded microcontroller, no firmware development, flash programming, or in-circuit emulator is required, which shortens qualification cycles and removes a whole class of field-update failure modes. The device supports individual downstream port power switching and overcurrent status inputs for compliant bus-powered and self-powered hub designs. Typical applications include standalone USB hubs, monitor and keyboard-display hubs, industrial and medical equipment USB expansion, and adding USB ports to embedded systems built around host processors without native hub capability. For design, provide 0.1 uF decoupling at each supply pin, strap configuration pins (or fit the optional EEPROM) for power-mode selection, and size port power switches per downstream port load.

TUSB2046BVFRG4 - 4-Port USB 2.0 Full-Speed Hub | Texas Instruments
The Texas Instruments TUSB2046BVFRG4 is a 4-port USB 2.0 full-speed hub controller operating at 12 Mbps from a 3.3 V supply, housed in a 32-pin LQFP (7x7 mm) package with an optional serial EEPROM interface and a 0C to +70C commercial operating range. A USB hub controller is an interface IC that expands a single upstream USB port into multiple downstream ports, handling enumeration, transaction translation at the protocol level, and port power management. It sits within the USB device hierarchy between the host controller and downstream peripherals, forming a sub-family of the broader USB interface and connectivity IC class within semiconductor interface products. Key features include one upstream port and four downstream ports compliant with the USB 2.0 specification at full speed (12 Mbps), support for both low-speed (1.5 Mbps) and full-speed downstream devices, an optional serial EEPROM interface for storing vendor ID / product ID configuration data, and overcurrent detection inputs with power-switch control outputs for per-port or ganged power switching. Implementation with a digital state machine instead of an embedded microcontroller eliminates firmware development and reduces BOM complexity. Technical depth: because the TUSB2046B is a pure hardware state-machine design, enumeration latency is deterministic and there is no firmware to qualify, update, or corrupt. The 3.3 V CMOS core with integrated 3.3 V regulator support keeps external components minimal, typically requiring only a 6 MHz or 48 MHz clock source, bypass capacitors, and the external power switches for downstream VBUS. Typical applications include PC monitor hubs, docking stations, industrial panel USB expansion, printer and multifunction peripheral front panels, and embedded systems requiring additional USB ports from a single host connection. The 12 Mbps full-speed rating suits HID devices, flash drives, and instrumentation rather than high-bandwidth video or mass-storage arrays. Design consideration: budget downstream VBUS power carefully - each downstream port may supply up to 500 mA at 5 V per the USB specification, so external power MOSFET switches and overcurrent sensing resistors must be sized for the aggregate load, and the OVERCURRENT inputs must be wired to the correct power-switch pins. This page synthesizes distributor pricing context, drop-in alternatives, lifecycle status, and practical design notes not found in the manufacturer datasheet alone.
TUSB2070PT - 7-Port USB 1.0 Hub Controller | Texas Instruments
The Texas Instruments TUSB2070PT is a CMOS 7-port USB hub controller that conforms to USB Specification Version 1.0, supplied in a 48-pin LQFP (PT) surface-mount package with a 0 °C to +70 °C commercial operating temperature range. According to the manufacturer datasheet, the device provides up to seven downstream ports from a single upstream connection, consolidating multiple legacy USB peripherals behind one host port. A USB hub controller is a type of USB interface controller: it sits between a host and one or more downstream devices, managing enumeration, power distribution, and data traffic across the bus. In the product-type hierarchy, a USB hub controller belongs to interface controllers, which are a subset of integrated circuits used for signal and protocol bridging. In an end system, the hub controller provides the physical fan-out layer between a single USB port and several peripherals, sitting below the host controller and above the physical USB transceiver layer. Key characteristics of the TUSB2070PT include support for up to seven downstream ports, full-speed operation under USB Specification 1.0 rules, a monolithic CMOS implementation, and a single upstream port connection for the host link. The 48-pin LQFP (PT) body gives generous pin count for port-level control and status signalling, while the industrial-temperature 0 °C to +70 °C range suits commercial and light-industrial equipment. Detailed electrical ratings such as supply voltage, I/O current, and internal oscillator tolerance are not stated in the retrieved data and must be confirmed against the manufacturer datasheet. Architecturally, the device implements the split-transaction, single-master USB 1.0 protocol stack internally, including host-controller interface signalling toward the upstream port and per-port transceiver interfacing toward downstream ports. It is a legacy architecture: modern designs normally use USB 2.0 high-speed hubs with integrated PHY and charge-pump regulators, so the TUSB2070 remains most relevant where a legacy USB 1.0 host must be expanded without changing the upstream device class. Typical uses include legacy personal-computer and embedded host systems needing additional full-speed USB ports, industrial data-acquisition panels, point-of-sale and print peripherals, and test benches that replicate USB 1.0 topologies. Because it is an established, widely supported part with a long service history, it is frequently found in repair and legacy-platform maintenance programs. Two design considerations matter most. First, the device is no longer the newest Texas Instruments 7-port hub: the manufacturer lists the TUSB2077A, also in a 48-LQFP package, as the replacement, so new designs should start there. Second, a 48-LQFP body demands careful decoupling and ground-plane continuity to keep USB signal integrity within the 1.0 specification budget. This page consolidates distributor availability signals, a drop-in replacement analysis for the 48-LQFP 7-port hub footprint, lifecycle guidance, and practical design notes that are not gathered together in a single manufacturer datasheet.
TUSB2077APT - 7-Port USB 2.0 Hub Controller | Texas Instruments
The Texas Instruments TUSB2077APT is a seven-port Universal Serial Bus hub controller operating as a full-speed USB 2.0 device at 12 Mbps. The controller is offered in a 48-pin LQFP package with a 7 mm by 7 mm body. It integrates USB hub logic with an optional serial EEPROM interface for product identification and configurable USB descriptors. A USB hub controller is an interface semiconductor that manages one upstream USB connection and multiple downstream ports. In the broader hierarchy, the TUSB2077APT belongs to the USB interface controller class, within interface integrated circuits and general-purpose semiconductor devices. Its seven-port architecture allows several USB peripherals to share one host controller while individual downstream connections can be enabled, disabled, or managed for power and enumeration requirements. The manufacturer identifies the TUSB2077APT as a seven-port full-speed USB 2.0 hub controller. It supports both bus-powered and self-powered operating modes, which allows the hub to be designed around the power budget of a host device or with a dedicated external supply. The optional serial EEPROM interface provides a path for storing descriptor information rather than relying only on the controller's default descriptor behavior. The EXTMEM control is connected to pin 47 and determines whether the optional EEPROM interface is enabled. According to the Texas Instruments TUSB2077A product page, driving EXTMEM high enables the optional EEPROM function and causes the vendor and product identifiers to use defaults, including enumeration as a General Purpose USB Hub. This makes EXTMEM an important PCB-level design and firmware-configuration decision. Typical uses include compact USB expansion products, computer peripherals, docking equipment, industrial control panels, test systems, and embedded systems that need several full-speed USB connections. A design must allocate upstream and downstream signal routing, verify power-source requirements, and configure the hub for either bus-powered or self-powered operation. The optional EEPROM path should be assessed early because its presence or absence affects descriptor customization and board population. Use the manufacturer pin-description table and package drawing when assigning all 48 pins and laying out the LQFP footprint. The downstream data paths require careful, impedance-conscious routing, while power and ground connections need enough copper area to support the selected operating mode. Designers should also confirm the configuration of EXTMEM at pin 47 and the intended behavior of the optional EEPROM interface. This product record combines the manufacturer's hub-function details, package and pin-count information, lifecycle information, sourcing context, and a conservative drop-in comparison. It also identifies practical design decisions that are easy to overlook: descriptor customization, EXTMEM configuration, power-mode selection, and validation of every candidate replacement before PCB substitution.
TUSB211RWBR - 480 Mbps USB 2.0 Signal Conditioner | TI
Texas Instruments TUSB211RWBR is a USB 2.0 high-speed signal conditioner designed to compensate for intersymbol interference in USB transmission channels. The device supports USB high-speed operation at 480 Mbps and is offered in a 12-pin X2QFN package measuring 1.6 mm by 1.6 mm. Its compact footprint makes the TUSB211 suitable for USB ports, cable extensions, peripheral connections, and embedded systems where signal loss can impair data integrity. A USB high-speed signal conditioner is an interface device placed within a USB 2.0 data path to improve signal quality across lossy interconnects. USB high-speed signaling uses differential data lines with significant bandwidth requirements, making cable length, connector transitions, PCB routing, and impedance discontinuities important system-level considerations. The TUSB211 belongs to the broader hierarchy of signal-processing interface ICs, interface ICs, and semiconductor devices designed to preserve data integrity between hosts, hubs, and USB peripherals. The primary function of the TUSB211 is to restore a degraded differential signal by compensating for channel-induced loss and intersymbol interference. Its USB 2.0 high-speed capability permits operation at 480 Mbps, allowing a link to remain functional over channels that would otherwise suffer from reduced eye opening or communication errors. Because the signal-conditioning stage operates within the data path, placement and layout can determine how effectively it corrects the intended channel. The RWB ordering code identifies the compact 12-X2QFN configuration used by TUSB211RWBR. Its small surface-mount package supports high-density PCB layouts, although accurate placement requires careful attention to differential-pair geometry, ground-return paths, and decoupling. The manufacturer product information lists the device as a USB 2.0 480-Mbps high-speed signal conditioner and identifies TUSB211RWBR as a 12-pin RWB package variant. Typical uses include USB host-to-peripheral links, USB-to-wireless bridges, industrial USB connections, peripheral docking systems, and cable-extension designs. The device is especially relevant when a connector, cable, or long PCB route introduces measurable high-speed attenuation and the designer wants to recover usable eye margin without replacing the entire USB interface implementation. When laying out a design, treat the conditioner as part of the high-speed channel rather than as an isolated IC. Verify differential impedance, minimize impedance discontinuities, provide the required local bypassing, and place the device where the channel losses remain predictable. Confirm signal-eye and compliance behavior with the complete connector, cable, host, and peripheral combination because channel length and topology can change the amount of correction required. This product page combines the exact TUSB211RWBR ordering information with practical USB signal-integrity guidance, compatibility-focused alternatives, and a side-by-side view of the electrical and packaging constraints that determine whether a substitution can be implemented without a PCB redesign.
TUSB212RWBR - USB 2.0 HS Signal Conditioner | Texas Instruments
Texas Instruments TUSB212RWBR is a USB 2.0 High-Speed signal conditioner with DC boost, packaged in a 12-X2QFN surface-mount package measuring 1.6 mm by 1.6 mm. It is designed to compensate for intersymbol interference caused by signal loss in a transmission channel. The device applies programmable AC boost and DC boost to restore degraded high-speed data signals while remaining agnostic to USB Low-Speed and Full-Speed traffic. A USB signal conditioner is a specialized interface IC that improves an already transmitted USB differential signal without changing the protocol implemented by the USB host, hub, or peripheral. Its position in the signal path is between the transmitter and a lossy channel. This makes the TUSB212RWBR part of the broader USB interface hierarchy: USB 2.0 interface IC, signal conditioning IC, redriver, and ultimately a semiconductor-based connectivity device. The principal feature of the TUSB212RWBR is programmable signal AC boost combined with DC boost. AC boost restores high-frequency signal amplitude lost through channel attenuation, while DC boost helps maintain the differential voltage required for reliable high-speed signaling. The manufacturer describes the implementation as patent pending and identifies USB On-The-Go compatibility as an additional design feature. Low-Speed and Full-Speed signal characteristics remain unaffected by the conditioning function. TUSB212RWBR is intended for USB 2.0 systems where trace losses, connector transitions, cable segments, or routing discontinuities reduce High-Speed eye margin. Conditioning is normally applied to the D+ and D+ differential pair as a complete pair rather than to either conductor independently. The correction must be tuned from measured eye diagrams because excessive boost can increase edge distortion, jitter, or emissions instead of improving receiver recovery. Typical deployments include USB hubs, cable assemblies, peripheral boards, host adapters, test equipment, and USB-to-storage or USB-to-network interfaces. In a hub, the conditioner can be placed near an upstream port so the signal entering a long cable is restored before attenuation becomes significant. In a peripheral, it can compensate for PCB routing from a connector to a USB controller. When applying the device, preserve the USB differential impedance recommended by the manufacturer and keep the D+ and D+ routes coupled and symmetric. Decoupling and boost configuration should follow the manufacturer reference layout. Confirm compliance through eye-height, jitter, rise-time, and emissions measurements because channel length, connector geometry, and host behavior determine the useful correction amount. This product page combines the manufacturer's USB 2.0 signal-conditioning description, exact TUSB212RWBR package information, extracted distributor pricing, and practical replacement analysis. It also distinguishes confirmed drop-in candidates from unsupported package or functional substitutions so engineers can make a PCB-level decision without relying on generic USB redriver recommendations.
TUSB2136PM - 2-Port USB 2.0 Hub Controller | Texas Instruments
Texas Instruments TUSB2136PM is a USB 2.0 two-port hub controller with an integrated general-purpose function controller, supplied in a 64-LQFP surface-mount package measuring 10 mm by 10 mm. It operates from a 3 V to 3.6 V supply and is specified for a 0 °C to 70 °C ambient operating range. The component is listed as active and is intended for USB interface and hub-controller designs. A USB hub controller is an interface integrated circuit that manages a USB host connection and coordinates attached USB devices. Within the product hierarchy, a USB 2.0 hub controller is an interface IC, a USB interface device, and a semiconductor. This TUSB2136 variant combines two-port hub control with a general-purpose function controller, allowing the hub function and device-side control logic to be consolidated within one package. The principal verified features are two USB 2.0 ports, a 3 V to 3.6 V operating-supply range, and integrated general-purpose function control. The controller is packaged in a 64-pin LQFP measuring 10 mm by 10 mm, providing a surface-mount implementation for compact USB equipment. The operating temperature range of 0 °C to 70 °C identifies it as a commercial-temperature option rather than an explicitly automotive-qualified or extended-temperature device. The TUSB2136PM combines a compound USB hub function with an embedded general-purpose 8052 MCU, as identified in the supplied datasheet result. This architecture is useful when downstream equipment needs local device handling, configuration logic, or peripheral control in addition to standard USB hub behavior. Its consolidated approach can reduce the number of discrete interface components required around a USB connection, although the complete implementation must be validated against the manufacturer datasheet and reference design. Typical uses include USB connection hubs, computer peripherals, docking equipment, and embedded USB interface products. Its two-port configuration is appropriate for systems that need to expose multiple USB connections through one upstream USB link. Integration of the general-purpose function controller is especially relevant to designs in which hub management must coexist with vendor-specific control behavior or device-specific handling. Designers should pay particular attention to USB signal routing, supply decoupling, and the exact pin assignments shown in the manufacturer documentation. Because the verified sources do not provide the complete pin table, crystal requirements, programming interface, USB transceiver details, or decoupling values, those items must be obtained from the official datasheet before schematic capture. No automotive qualification or regulatory status beyond the supplied active-status information should be inferred. This page combines the verified USB version, port count, supply range, package, temperature range, lifecycle status, and distributor availability information with practical integration guidance. It also distinguishes documented characteristics from unknown electrical details and avoids presenting unverified pinout or replacement claims as drop-in-compatible alternatives.
TUSB2140BN USB 1.1 4-Port Hub Controller | Texas Instruments
The Texas Instruments TUSB2140BN is a USB 1.1 interface controller for four-port USB hub applications, supplied in a 40-pin DIP package measuring 0.600 inches, or 15.24 mm, across. The device is identified by distributors as a USB interface bus controller with integrated transceiver characteristics, and it is associated with an I2C microcontroller interface in supplier documentation. The verified product information confirms a through-hole DIP format, commercial temperature grade, and 40 terminals. It also confirms availability through multiple distributors, including 6,048 pieces reported by Heisener and a unit price of $6.4513 as of 2026-10-30. The TUSB2140BN is therefore positioned as a legacy USB hub controller for systems requiring four downstream USB ports rather than a general-purpose USB interface transceiver. Its 40-DIP package favors prototype boards, legacy industrial equipment, and expansion systems where through-hole assembly is acceptable. The supplied listings do not provide a complete official electrical table, exact pin assignments, transfer-rate details beyond USB 1.1, or a current manufacturer lifecycle statement. Those parameters remain identified as data needed rather than being inferred from similar devices. A practical design review should therefore begin with the official TUSB2140B datasheet, especially for D+/D- routing, power-switching requirements, crystal or clock connections, I2C address programming, and termination requirements. In a USB hub design, the controller manages downstream-port enumeration and shared upstream-bus behavior, while external power-distribution and protection components determine how safely multiple peripherals can be connected.
TUSB2140N - 4-Port USB 2.0 Hub Controller | Texas Instruments
Texas Instruments TUSB2140N is a 4-port USB 2.0 hub controller with embedded function, a maximum clock frequency of 48 MHz, I2C bus compatibility, and a 40-pin through-hole DIP package. It is designed for industrial USB hub equipment requiring multiple downstream ports and centralized control. The verified sources identify TUSB2140N as the original 40-PDIP member of the TUSB2140 family and note that it was replaced by TUSB2046B. A USB hub controller is an interface IC that manages traffic between one upstream USB host connection and multiple downstream USB ports. Within the product hierarchy, it is a USB interface controller, bus controller, interface IC, and semiconductor. By organizing USB connectivity and exposing configuration functions through a compatible control bus, this type of device reduces the amount of discrete logic required in a multiport USB product. The TUSB2140N provides four downstream hub ports, operates up to 48 MHz, supports I2C compatibility, and is available in a 40-terminal rectangular DIP package. The verified distributor data classifies it as an industrial-temperature component with through-hole terminals. These characteristics make it relevant to legacy industrial USB hubs, embedded USB expansion equipment, and systems designed around the original TUSB2140 interface rather than newer hub controllers. Technically, the device combines USB host-interface management and an embedded function in one controller. Its 48 MHz maximum operating frequency supports the clocking requirements associated with this USB 2.0 hub-controller generation, while I2C compatibility offers a practical path to configuration and supervisory control. The 40-pin DIP format favors through-hole assembly and repairability, but it consumes considerably more board area than contemporary surface-mount hub controllers. Typical applications include industrial USB hubs, embedded test equipment, peripheral aggregation systems, legacy USB expansion cards, and OEM products that retain the TUSB2140 architecture. Because the part is an older through-hole design, engineers should also assess modern surface-mount alternatives or the indicated TUSB2046B successor when new PCB area, sourcing, or lifecycle constraints favor redesign. The primary design consideration is lifecycle and availability. Verified marketplace data states that TUSB2140N was replaced by TUSB2046B, while current stock and pricing are offered through brokers and distributors. For new production, confirm lifecycle status, exact electrical compatibility, and pin-level equivalence before substituting any successor; a USB hub change can affect enumeration, power management, and downstream-port behavior. This page consolidates verified distributor specifications, the replacement relationship, source links, and engineering selection guidance. It distinguishes documented TUSB2140N attributes from unavailable parameters, helping procurement and design engineers make a grounded legacy-support or migration decision.
TUSB214RWBR - USB 2.0 HS Signal Conditioner | Texas Instruments
Texas Instruments TUSB214RWBR is a USB 2.0 high-speed signal conditioner with DC boost and an integrated BC1.2 Charging Downstream Port controller. It supports USB 2.0, OTG 2.0, and BC1.2 operation, with low-, full-, and high-speed signaling across a 3 V to 3.6 V supply range. The device is packaged in a compact 12-pin X2QFN package measuring 1.6 mm by 1.6 mm. A USB signal conditioner is an interface IC that compensates for attenuation, distortion, and timing degradation introduced by connectors, cables, PCB traces, and other interconnect elements. Positioned within the broader USB interface hierarchy, it sits between a USB host or device controller and a physical USB connection. Its DC boost function helps maintain usable signal amplitude through lossy channels, while its integrated charging-port controller simplifies compliance with BC1.2 downstream-port requirements. The TUSB214 supports LS, FS, and HS signaling and provides selectable signal gain for high-loss applications. Its D1P/M and D2P/M inputs are interchangeable, allowing the same device-oriented layout to work in host or device applications. The device also supports daisy-chain operation, which can simplify cascading through multiple lossy cable or connector sections when a single conditioner is not sufficient. The BC1.2 charging function is configurable through a pin strap or I2C. This provides a practical choice between hardware-configured designs and firmware-controlled implementations. The TUSB214 additionally features very low USB disconnect and shutdown power consumption, making it suitable for power-conscious USB equipment where inactive-state leakage can influence battery life or system thermal performance. Typical applications include USB 2.0 peripheral connections, host-to-cable interfaces, device-to-cable interfaces, and systems that require an integrated downstream charging-port controller. It is particularly useful when PCB routing, connector transitions, or cable loss could degrade high-speed USB data. The 1.6 mm by 1.6 mm X2QFN footprint supports compact designs, although its fine pitch requires careful layout, assembly, and inspection practices. The principal design consideration is placement. The conditioner should be positioned near the loss or connector transition it is intended to correct, while its data traces should remain short, properly terminated, and routed away from noisy power or high-current paths. Designers should also confirm the configured BC1.2 mode, enable state, and signal-gain setting against the final system behavior. This product page combines the TUSB214 family characteristics with package-specific ordering information, application guidance, drop-in alternatives, and a practical comparison framework. It is intended to support component selection and board-level implementation decisions rather than simply repeat the basic catalog description.
