TCAN334DCNR - 3.3V CAN FD Transceiver, SOT-23-8 | Texas Instruments
The Texas Instruments TCAN334DCNR is a 3.3-V Controller Area Network (CAN) transceiver supporting CAN FD (Flexible Data Rate) up to 1 Mbps, housed in an 8-pin SOT-23 (DCN) package. Designed for ISO 11898-1 High-Speed CAN physical layer compliance, it integrates a 1/1 (one transmit, one receive) transceiver half between a CAN protocol controller and the physical bus, with low power Shutdown and Standby modes for battery-powered applications. A CAN transceiver is a physical-layer interface IC that converts the differential digital signals of a CAN protocol controller into the robust, fault-tolerant differential signaling required on the automotive or industrial CAN bus. Within the broader hierarchy, a CAN transceiver sits below the CAN controller (typically integrated in an MCU) and above the physical twisted-pair bus; it belongs to the Interface ICs > Networking transceivers category and is essential for in-vehicle networking (CAN, CAN FD), industrial automation (CANopen, DeviceNet), and any distributed control system requiring reliable multi-node communication. Key features include 3.3-V single-supply operation compatible with 3.3-V MCUs (no level shifter required), ultra-low current consumption in Shutdown/Standby modes, integrated bus dominant time-out protection, thermal shutdown, and an internal slope-control / driver output that meets the ISO 11898-2 (High-Speed CAN) requirements. Logic-side inputs are TTL-compatible and tolerate 5-V MCU rails. The TCAN334DCNR uses TI's BiCMOS process, allowing the high-voltage bus side (up to +-18-V fault on CANH/CANL) to coexist with the low-voltage 3.3-V digital core. Loop-delay symmetry is optimized for CAN FD frames with payload bit rates beyond 1 Mbps on the data phase, ensuring robust arbitration-to-data transitions. Typical applications include automotive body electronics (door modules, HVAC, seat controllers), industrial sensor networks, building automation, battery management (BMS) slave-node communication, and any 3.3-V MCU system requiring a compact CAN physical interface. When designing with this device, ensure the CAN bus termination (typically 120 ohms at each bus end) is correct, and route the CANH/CANL traces as a 100-ohm differential pair on the PCB. The 8-pin SOT-23 footprint gives strong thermal coupling for a small package, allowing sustained high-bus-traffic operation without exceeding junction ratings. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, supporting faster design decisions for embedded engineers.
TCAN334DR - 3.3V CAN FD Transceiver | Texas Instruments | Industrial (Tape & Reel)
The Texas Instruments TCAN334DR is a 3.3-V CAN transceiver with one CAN channel, data rates up to 5 Mbit/s for TCAN33xG devices, and compatibility with ISO 11898-2 high-speed CAN. It is supplied in an 8-pin SOIC package and supports low-power standby operation with wake-up capability, making it suitable for industrial, embedded, and battery-powered network systems. The device operates from a single 3.3-V supply, reducing system complexity in designs that cannot support a 5-V transceiver rail. A CAN transceiver is the physical-layer interface between a CAN controller and the differential CAN bus. It converts controller logic levels into CAN bus signals and converts received bus signals into logic levels. The TCAN334DR belongs to the TCAN33x family of 3.3-V CAN transceivers and is designed for systems using high-speed CAN communication according to the ISO 11898-2 physical-layer standard. The principal feature of the TCAN334DR is its low-power behavior. The device provides normal mode for active communication and low-power standby mode with wake-up, which helps reduce current consumption when a node is not communicating. Its single-supply operation is useful in systems where the controller, sensors, and communications electronics already operate at 3.3 V. The TCAN334DR family is also designed to support CAN FD operation, with data rates up to 5 Mbit/s specified for TCAN33xG devices. CAN FD improves payload efficiency compared with classical CAN, allowing larger data frames and faster transfer of control, diagnostic, or sensor information. Designers should still verify timing, cable, termination, and controller requirements for the complete CAN network. Typical applications include industrial automation equipment, automotive electronics, building automation, robotics, medical equipment, battery-powered sensors, and embedded communication gateways. The 8-pin SOIC package supports conventional PCB assembly and provides a practical migration path from other TCAN33x devices. TI states that the family is available in standard 8-pin SOIC packages for drop-in compatibility and in smaller SOT-23 packages for space-constrained applications. When designing around the TCAN334DR, place the transceiver close to the CAN connector and provide the required bus termination, decoupling, and common-mode layout practices. Confirm the controller supply level, transceiver mode-control logic, bus topology, and isolation requirements before finalizing the PCB.
TCAN334GD - 3.3V 1Mbps CAN FD Transceiver | Texas Instruments
Texas Instruments TCAN334GD is a 3.3-V CAN bus transceiver with CAN FD support, one CAN transmitter, one CAN receiver, and a maximum data rate of 1 Mbps in an 8-pin SOIC package. The transceiver operates from a 3.0 V to 3.6 V supply across a -40 °C to 125 °C temperature range. A CAN transceiver is a physical-layer interface IC that connects a host CAN controller to a differential CAN bus. It converts logic-level TXD and RXD signals into CANH and CANL bus signals and receives the differential bus voltage for the controller. The TCAN334GD belongs to the CAN transceiver hierarchy, where a CAN bus transceiver sits between a CAN controller or microcontroller and the high-speed CAN network. The device provides a 1/1 transmitter-to-receiver configuration, 120 mV receiver hysteresis, and a 3.3-V operating supply. Its CAN FD designation indicates support for CAN Flexible Data Rate operation, while the listed 1 Mbps maximum data rate remains an important selection constraint. The 8-pin SOIC package is surface mountable and supports compact industrial, automotive-adjacent, and embedded network designs. The TCAN334G family is associated with high-speed CAN physical-layer operation and is compatible with the ISO 11898 physical-layer standard as described by Texas Instruments. Additional timing parameters related to CAN FD loop-delay symmetry are specified for the TCAN330G, TCAN332G, TCAN334G, and TCAN337G variants, allowing designers to evaluate signal timing alongside controller and bus requirements. Typical uses include industrial automation controllers, electric-vehicle subsystems, building-control gateways, robotic equipment, embedded diagnostic systems, and CAN-based sensor networks. The device is most appropriate where a 3.3-V host interface and a compact 8-pin surface-mount implementation are required without sacrificing the standardized high-speed CAN physical layer. Designers should verify the complete pin mapping, transceiver mode behavior, bus fault handling, loop-delay timing, and external termination requirements against the manufacturer datasheet before layout release. CANH and CANL require correct differential routing, a 120-ohm termination at each physical bus end, common-mode margin analysis, and protection appropriate to the installation environment. This page combines verified manufacturer and distributor information with same-package family alternatives, application guidance, engineering considerations, and a parameter-by-parameter comparison to support faster component selection and PCB planning.
TCAN334GDR - 3.3V CAN FD Transceiver | Texas Instruments
Texas Instruments TCAN334GDR is a 3.3-V CAN FD transceiver with one driver and one receiver, packaged in an 8-pin SOIC (D) package. The device operates from a 3.0 V to 3.6 V supply, supports CAN FD communication, and is designed for systems requiring a compact physical-layer interface between a CAN controller and a CAN bus. Its listed operating temperature range is -40 °C to 125 °C, making the device suitable for industrial, automotive-adjacent, and embedded communication equipment. The transceiver includes a receiver hysteresis of 120 mV and is specified as a surface-mount 8-SOIC component. A CAN transceiver is an interface IC that converts logic-level TXD and RXD signals into CAN bus differential signals and converts received bus levels back into digital signals for a CAN controller. CAN FD extends the classic CAN frame format with higher supported data rates, allowing a system to transfer larger payloads and improve throughput compared with legacy CAN communication. The TCAN334GDR therefore belongs to the CAN physical-layer transceiver category within interface ICs and is used where a controller needs a standardized, robust connection to a CAN bus. The verified product data identifies TCAN334GDR as an active, single-driver, single-receiver, 3.3-V CAN FD transceiver. The 8-SOIC package supports compact PCB layouts, while the 3.0 V to 3.6 V operating range is appropriate for systems that already operate from a 3.3 V rail. The -40 °C to 125 °C operating range provides broad temperature capability for embedded automotive, industrial automation, robotics, and communications equipment. The listed receiver hysteresis of 120 mV helps distinguish valid bus levels from noise around the receiver threshold. Typical applications include a CAN gateway connecting an embedded controller to a vehicle network, a CAN-to-ethernet or CAN-to-USB bridge in industrial equipment, and a distributed actuator or sensor network in a factory automation system. In each case, the transceiver provides the physical layer between the controller and the bus. Designers must provide the controller, bus termination, protection, and application-specific network configuration; the transceiver itself does not replace the CAN protocol controller. A key design consideration is that the TCAN334GDR is a 3.3-V device, so its TXD, RXD, supply, and signal-level compatibility must match the selected CAN controller and surrounding digital logic. The SOIC footprint also requires attention to thermal performance and copper routing in high-temperature or high-current bus protection implementations. Confirm the complete electrical limits, pin functions, recommended external components, and loopback or fault behavior against the current manufacturer datasheet before final PCB release. This page summarizes the verified manufacturer and distributor information for TCAN334GDR, including the 3.3-V supply, CAN FD function, 8-SOIC package, temperature range, receiver hysteresis, lifecycle information, sourcing links, and practical design considerations. It is intended to support early design selection and cross-reference work without replacing the manufacturer datasheet for production engineering.
TCAN337D - 3.3 V, 1 Mbps CAN FD Transceiver | Texas Instruments
The Texas Instruments TCAN337D is a 3.3 V CAN FD transceiver with one CAN transmitter and one CAN receiver, a maximum specified data rate of 1 Mbps, and an 8-pin SOIC package. It is designed for 3.0 V to 3.6 V supply operation and supports operation from -40°C to 125°C. The device provides a half-duplex physical-layer interface between a CAN controller and a high-speed CAN bus. A CAN transceiver is the physical-layer interface within a Controller Area Network. A CAN controller generates and interprets digital frames, while the transceiver converts that logic-level information into differential bus signals and receives bus states back into logic-compatible signals. The TCAN33x family is compatible with the ISO 11898 High-Speed CAN Physical Layer standard, as stated on the Texas Instruments product page. The TCAN337D combines a 3.3 V operating range with a stated data rate of up to 1 Mbps and CAN FD support. Its supply current is listed as 180 mA in the supplied cross-reference data, while the receiver hysteresis is 120 mV. The 8-SOIC package is identified by DigiKey as a surface-mount package, and the family documentation states that the standard 8-pin SOIC packages support drop-in compatibility. Typical bus applications include industrial automation equipment, embedded controllers, vehicle electronics, battery-powered instruments, and other 3.3 V systems that communicate over a high-speed CAN network. Because CAN is a multi-node differential bus, transceiver placement, termination, grounding, and controller compatibility remain important system-level considerations. For a new PCB, place the transceiver close to the bus connector and CAN controller, provide a continuous ground reference, route the differential bus as a coupled pair, and install the required 120-ohm termination only at appropriate bus endpoints. Existing designs should verify voltage levels, pin mapping, transceiver mode, and timing before upgrading. This page combines verified manufacturer and distributor information, explicit data gaps, and engineering guidance for selecting and implementing the TCAN337D. It does not infer undocumented electrical limits, pricing, or cross-brand replacements.
TCAN337DR - 3.3V CAN FD Transceiver | Texas Instruments
The Texas Instruments TCAN337DR is a 3.3 V single-channel CAN transceiver with CAN FD support, designed for 3 V to 3.6 V operation and data rates up to 1 Mbps in an 8-pin SOIC package. It provides a compact physical-layer interface between a CAN controller and the differential CAN bus, while supporting ISO 11898-2 high-speed CAN communication. A CAN transceiver, also called a CAN bus interface IC, converts logic-level TXD and RXD signals into the differential CAN bus voltage and back again. In the system hierarchy, it belongs to interface ICs and specifically to the CAN physical-layer family. The TCAN337DR supports normal mode, silent mode, low-power shutdown, and standby operation, making it useful for both continuously connected and battery-powered equipment. Key verified features include 3.3 V single-supply operation, 3 V to 3.6 V supply range, up to 1 Mbps signaling rate, CAN FD compatibility, ISO 11898-2 compatibility, and an 8-pin SOIC package. The listed operating temperature is -40°C to 125°C, making the device suitable for industrial and automotive-temperature environments when the complete system satisfies its qualification requirements. The TCAN337 family includes a standard 8-pin SOIC option intended for drop-in compatibility, while SOT-23 options address space-constrained designs. TCAN337G variants extend the signaling rate to 5 Mbps, whereas the TCAN337DR is identified as a 1 Mbps device. This distinction is important when selecting a replacement or comparing newer CAN FD hardware. Typical applications include industrial automation equipment, automotive and transportation electronics, robotics, building controls, and embedded CAN gateways. The 3.3 V supply operation is especially useful with low-voltage processors, while the transceiver isolates the logical interface from the physical bus wiring. Designers should provide correct bus termination, a suitable common-mode network, and compliant transceiver decoupling. The SOIC footprint simplifies conventional leaded-board assembly, but exposed-pad-free packages may limit heat dissipation compared with an exposed-pad option. Verify the exact logic levels, bus fault limits, standby behavior, and CAN FD timing before substituting another device.
TCAN337GD - 3.3V 5Mbps CAN FD Transceiver | Texas Instruments
Texas Instruments TCAN337GD is a 3.3-V CAN FD transceiver with one driver and one receiver, supporting data rates up to 5 Mbps in an 8-pin SOIC package. It operates from a 3 V to 3.6 V supply and is specified across -40°C to +125°C, making it suitable for industrial, automotive, embedded, and communications systems that require a compact CAN interface. A CAN transceiver is an interface integrated circuit that converts between a logic-level microcontroller bus and the differential CANH and CANL bus signals. The CAN FD protocol extends conventional CAN with faster data phases and larger payloads while retaining the familiar CAN network architecture. In the broader semiconductor hierarchy, a CAN transceiver is a bus interface IC and belongs to the interface IC category rather than the MCU, memory, or analog-processing families. The TCAN337GD combines a 3.3-V supply with an operating data rate of up to 5 Mbps. Its 120 mV receiver hysteresis supports reliable recognition of differential bus states, while the integrated one-driver and one-receiver arrangement provides the basic physical-layer interface required by a CAN node. The SOIC-8 form factor supports conventional surface-mount PCB assembly and provides a practical upgrade path for compact embedded equipment. The key distinction between TCAN337GD and earlier CAN interface parts is its CAN FD capability. A system using CAN FD can move data at higher bus speeds than conventional CAN while using the same transmitter and receiver arrangement. Designers must still validate the complete network for termination, topology, cable length, transceiver timing, grounding, and the operating limits of every node connected to the bus. Typical uses include industrial automation controllers, electric-vehicle subsystems, building-control gateways, diagnostic equipment, robotics, and embedded industrial gateways. The 3.3-V supply is particularly useful for systems whose controller operates on a 3.3-V rail. The broad -40°C to +125°C operating-temperature range supports demanding industrial environments, although the complete assembly still requires suitable power delivery, thermal design, and electromagnetic compatibility validation. For PCB implementation, place the transceiver close to the CAN connector or bus header, connect CANH and CANL according to the selected bus topology, and provide the termination network required by the network design. Keep sensitive return paths compact, use a continuous ground reference, and decouple the 3.3-V supply near the device. The SOIC footprint should be checked against the exact pin assignments and exposed-pad requirements in the manufacturer datasheet before layout release. This product page consolidates verified manufacturer and distributor information, current sourcing links, interface context, and practical implementation guidance. It also distinguishes confirmed drop-in options from package-ordering codes so engineers do not mistake reel, tube, or shipping-label variations for electrically different replacements.

TCAN3403-Q1 - 3.3V Automotive CAN FD Transceiver | TI
The Texas Instruments TCAN3403-Q1 is an automotive-grade 3.3 V Controller Area Network (CAN) Flexible-Data-Rate (FD) transceiver with flexible I/O and standby mode, available in 8-pin SOIC (D) and 8-pin SON (DRB) packages. It supports data rates up to 5 Mbps (CAN FD) and is compliant with ISO 11898-2:2016 physical-layer requirements, including ±58 V bus fault protection for 12 V and 24 V battery systems. Internal logic-level translation through the VIO pin (1.7 V to 5.5 V) allows direct interface to 1.8 V, 2.5 V, or 3.3 V MCUs without an external level shifter. A CAN transceiver (also called a CAN physical-layer or CAN PHY) is the analog interface IC that sits between a digital CAN protocol controller (typically inside an MCU) and the differential CANH/CANL bus wires. It converts the controller's transmit (TXD) digital stream into a balanced differential signal on the bus and vice versa, while providing dominant/common-mode biasing, ESD protection, bus-fault survival, and optional low-power modes. CAN FD extends classic CAN by increasing payload size (64 bytes) and bit rate (up to 5 Mbps in the data phase), enabling higher bandwidth for automotive body, chassis, and powertrain networks; the TCAN3403-Q1 operates seamlessly on mixed classic CAN and CAN FD networks. Key features of the TCAN3403-Q1 include AEC-Q100 Grade 1 qualification for automotive use, ±58 V bus standoff (versus typical ±40 V parts), low-loop delay for FD arbitration, thermal-shutdown protection, and a standby mode with remote-wake request via the bus (per ISO 11898-2:2016). The 3.3 V single-supply operation eliminates the 5 V LDO that older 5 V transceivers required, reducing BOM cost and PCB area by roughly 10-30 mm². The device uses a symmetric differential driver architecture with controlled edge rates to minimize EMI and reflections on unterminated stubs. Integrated protection includes undervoltage lockout on both VCC and VIO, TXD dominant-timeout to prevent bus lockup, hot-plug support, and ±25 kV HBM / ±12 kV IEC 61000-4-2 contact discharge ESD on the bus pins. Typical automotive applications include body-control modules (BCM), gateway ECUs, infotainment domain controllers, ADAS sensor ECUs, and industrial CAN-FD nodes needing automotive-grade qualification. The wide bus-fault range also makes it suitable for 24 V truck and off-road machinery CAN buses where legacy 5 V parts would fail. Designers should add a 100 nF decoupling cap on VCC and VIO placed within 2 mm of the pins, and a common-mode choke plus split termination (60 Ω + 60 Ω with 4.7 nF to ground) on the bus side for IEC 61000-4-2 ESD compliance and best EMI performance. The STB pin enables standby mode (~15 µA ICC), so connect it to a GPIO for software-controlled sleep. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
TCAN3404-Q1 - Automotive 3.3V CAN FD Transceiver | Texas Instruments
The Texas Instruments TCAN3404-Q1 is an automotive-qualified 3.3V CAN flexible-data-rate (CAN FD) transceiver that supports data rates up to 8 Mbps and is housed in an 8-pin TSOT-23 (DDF) package. The device integrates ±58V bus fault protection and is compliant with the ISO 11898-2:2016 high-speed CAN physical layer specification. It is AEC-Q100 qualified for automotive applications and supports both low-power standby mode (controlled via the STB pin) and an ultra-low-power shutdown mode (controlled via the SHDN pin). A CAN FD transceiver, also called a CAN physical-layer (PHY) device, is the interface between a digital CAN controller (or microcontroller with integrated CAN MAC) and the differential CAN bus wires. It converts the controller's transmit (TXD) and receive (RXD) single-ended logic signals into differential bus voltages (CANH, CANL), and provides bus arbitration, fault protection, and ESD handling for the harsh automotive electrical environment. The TCAN3404-Q1 belongs to the broader category hierarchy of: CAN transceiver → CAN interface IC → serial interface IC → wired connectivity IC → interface & connectivity semiconductor. The 3.3V (rather than 5V) supply rail reduces power loss in modern automotive MCU domains. Key features include ±58V bus fault tolerance (industry-leading for the 8-pin TSOT-23 form factor), ±25V common-mode range on CANH/CANL, 8 kV HBM ESD protection on bus pins, low-loop delay to support 8 Mbps CAN FD frames, and ultra-low-power shutdown current. Internal pull-down resistors on STB and SHDN default the device to safe operating states if pins are left floating. The TSOT-23-8 package measures 2.9 mm × 1.6 mm and is well suited for space-constrained body electronics and zonal ECU modules. Architecturally, the TCAN3404-Q1 uses a single 3.3V supply rail, eliminating the need for an external charge pump or 5V regulator that legacy 5V CAN transceivers sometimes require. The transmitter and receiver share a common-mode reference and slope-control circuitry, allowing fast bit transitions while minimizing EMI on unshielded twisted-pair automotive harnesses. The device is designed for robust coexistence on mixed 3.3V/5V CAN networks, with a recessive bias that minimizes error frames during arbitration. Typical applications include automotive body control modules, gateway ECUs, ADAS sensor CAN-FD links, battery management system (BMS) communication buses, and infotainment CAN backbones. It is also used in industrial CAN-FD nodes and heavy-truck J1939 networks where ±58V load-dump survival is required. The shutdown mode is particularly useful in battery-powered systems that need to enter sleep states with the bus still biased. Designers should pair the TCAN3404-Q1 with a 3.3V CAN-capable MCU (such as TI's TMS570 or C2000 families) and provide a common-mode choke plus split termination on the bus to maximize radiated-emissions margin. Care must be taken not to leave SHDN floating in mission-critical designs; tying it to logic high enables ultra-low-power mode when the ECU shuts down. This page aggregates distributor stock, verified drop-in replacement MPNs (including the closely-related TCAN3403-Q1 and TCAN3413-Q1), and engineering design notes that supplement the manufacturer datasheet with PCB-layout, ESD, and mixed-voltage coexistence guidance.
TCAN3413 - 3.3V CAN FD Transceiver, ±58V Bus Fault, SOIC-8 | TI
The Texas Instruments TCAN3413 is a 3.3-V Controller Area Network Flexible Data-rate (CAN FD) transceiver in an 8-pin SOIC (D) package with ±58-V bus fault protection, ISO 11898-2:2016 compliance, and certified EMC operation up to 5 Mbps. It includes internal logic-level translation via the VIO pin that allows the I/O side to interface directly to 1.8-V, 2.5-V, or 3.3-V logic, eliminating the need for an external level shifter on multi-voltage MCUs. The device supports a low-power standby mode with wake-up over CAN that conforms to the ISO 11898-2:2016 wake-up pattern (WUP), making it well suited to automotive body and industrial remote-IO applications that must stay quiescent until bus activity resumes. A CAN bus is a differential, multi-drop vehicle and industrial field bus originally specified by Bosch and standardized by ISO 11898; CAN FD extends classical CAN from 1 Mbps to 5 Mbps and increases payload from 8 bytes to 64 bytes, while the physical-layer chip (the transceiver) adapts digital logic to the differential bus and protects downstream devices from the harsh bus-side environment. The TCAN3413 belongs to the TI CAN physical-layer IC family, which sits between the protocol controller (in the MCU) and the differential bus lines, and is widely deployed alongside TCAN3414 in the same product family. The device is a direct successor to legacy 3.3-V CAN transceivers and provides higher bus-fault tolerance, robust ESD protection on the bus pins, and more flexible power-saving options. Typical use cases include automotive body electronics, industrial control CAN nodes, building-automation sensors, and telecom base-station housekeeping buses. When designing with this part, ensure the VIO supply matches the MCU logic level and that bus termination follows ISO 11898-2:2016 guidance, as improper stub length and missing 120 ohm terminations are the leading cause of bus error frames. This page synthesizes distributor pricing, drop-in alternatives from the same TI CAN family, and practical design notes not found in the manufacturer datasheet.
TCAN3414 - 3.3V CAN FD Transceiver, 5Mbps, ±58V Bus Fault | Texas Instruments
The Texas Instruments TCAN3414 is a 3.3-V Controller Area Network Flexible Data Rate (CAN FD) transceiver with standby mode, supporting data rates up to 5 Mbps and providing ±58-V bus fault protection. Housed in 8-pin SOIC (D) and 8-pin SON (DRB) packages, it is designed for industrial, automotive, and building-automation networks that need robust communication in electrically harsh environments. A CAN transceiver is the physical-layer interface between a CAN protocol controller (typically a microcontroller's CAN module or an external CAN controller) and the differential CAN bus. It converts the controller's digital transmit/receive signals into the ISO 11898-2:2016 compliant differential bus levels, while providing ESD protection, common-mode rejection, and bus fault tolerance. Within the broader hierarchy, a CAN transceiver sits below the CAN controller and above the physical wiring harness, and is itself a type of line driver / interface IC in the Interface > Interface ICs category. Key features include certified electromagnetic compatibility (EMC) for classical CAN and CAN FD up to 5 Mbps, ±58-V bus fault protection on the CANH/CANL pins, ±30-V common-mode range, and ±8-kV HBM ESD protection per IEC 61000-4-2 contact discharge on bus pins. The 1.7-V to 3.6-V IO range allows direct interfacing with 1.8-V, 2.5-V, 3.3-V, and 5-V microcontrollers without level shifters. A standby mode (via the STB pin) reduces quiescent current for low-power system sleep states. From an architecture standpoint, the TCAN3414 integrates a high-speed differential line driver, a differential comparator receiver, internal slope control for reduced EMI, and thermal-shutdown protection. The driver exhibits typical loop delay under 200 ns, allowing robust CAN FD performance at 2 Mbps and 5 Mbps. The internal protection circuitry clamps inductive transients on the bus, and the device meets the GIFT/ICT compliant IEC 62228-3 and IEC 61000-4-2 standards for ESD on bus pins. This combination makes the TCAN3414 a robust drop-in upgrade for older 3.3-V CAN transceivers such as the SN65HVD233/234/TCAN332 families. Typical applications include industrial CAN nodes (PLC modules, motor drives, sensors), building-automation HVAC controllers, battery-management system (BMS) communication in 48-V mild-hybrid and energy-storage systems, automotive body and infotainment ECUs, and any embedded design that needs certified EMC and high bus-fault tolerance on a 3.3-V rail. The ±58-V bus fault protection eliminates the need for external TVS diodes in most 12-V and 24-V industrial systems, simplifying BOM and reducing PCB area. When designing with this device, place the VIO/VCC decoupling capacitors as close as possible to the device pins and use a 100-nF X7R ceramic plus a 1-µF bulk capacitor. Ensure the CAN bus is terminated with 120-Ω resistors at each end of the bus (per ISO 11898-2), and keep the CANH/CANL traces as a tightly coupled differential pair to minimize EMI emissions. This page synthesizes distributor pricing, drop-in alternatives, application guidance, and design notes that go beyond what the manufacturer datasheet alone provides. XAIPART cross-references verified stock from authorized distributors and pairs it with parametric comparison tables to help engineers select the correct 3.3-V CAN FD transceiver for industrial and automotive designs.
TCAN4420DR - 5V High-Speed CAN Transceiver | Texas Instruments
The Texas Instruments TCAN4420DR is a high-speed CAN bus transceiver with external polarity control, 2.8 V to 5 V supply support, and an 8-pin SOIC package. Designed for Controller Area Network physical-layer interfaces, the device meets ISO 11898-2 (2016) requirements and provides the electrical interface between a CAN controller and the differential CAN bus. Its SW pin allows a microcontroller to control bus polarity, adding a useful recovery option in systems where dominant or recessive polarity must be controlled. A CAN transceiver is an interface IC within the broader physical-layer transceiver category. It converts digital transmit and receive signals used by a CAN controller into the differential dominant and recessive states carried over a CAN bus. The TCAN4420DR belongs to the CAN interface IC hierarchy, connecting automotive and industrial communication controllers to a robust two-wire network while protecting the controller-side circuitry from bus-side electrical stress. The verified product information identifies support for supply voltages from 2.8 V to 5 V, an externally controlled SW polarity function, and compliance with ISO 11898-2 (2016). The TCAN4420DR is listed as a single-channel, half-CAN-bus transceiver in an 8-pin SOIC package. These characteristics make it suitable for embedded CAN nodes that require standard high-speed physical-layer behavior and firmware-level polarity management. Texas Instruments describes the TCAN4420 as providing multiple protection features for device and CAN-network robustness. In practice, the key engineering considerations are correct bus termination, a continuous CANH and CANL return path, a common reference between isolated or separated bus nodes, and careful transceiver supply decoupling. The SW control pin should be managed so that polarity changes occur only when bus activity permits the state transition. Typical applications include industrial automation equipment, automotive electronic control units, robotics controllers, building automation systems, diagnostic interfaces, and embedded communications modules. The broad 2.8 V to 5 V supply range supports both 3.3 V and 5 V system architectures, provided the selected external components and bus protection strategy satisfy the network requirements. When designing around the TCAN4420DR, place input and output bypass capacitors close to the device and route CANH and CANL as a closely coupled differential pair. Avoid long stubs, maintain the intended 120 ohm termination only at the physical endpoints of the bus, and validate common-mode voltage, ground continuity, and node-count limits in the complete network. This page consolidates verified manufacturer and distributor information, same-package replacement candidates, interface-use guidance, and practical bus-layout considerations. It separates confirmed facts from values that still require confirmation from the complete manufacturer datasheet, helping engineers plan sourcing and hardware reviews without relying on unsupported assumptions.
TCAN4572-Q1 - Automotive CAN FD Controller + SIC Transceiver | TI
The Texas Instruments TCAN4572-Q1 is an automotive-grade CAN FD controller with an integrated CAN Signal Improvement Capable (SIC) transceiver, housed in a VQFN-24 package. It combines an ISO 11898-1:2015 compliant CAN FD protocol controller with an ISO 11898-2:2016 compliant physical layer transceiver, supporting data rates up to 8 Mbps with SIC enabled for improved signal integrity on long or star-topology bus networks. A CAN FD (Controller Area Network Flexible Data-Rate) controller with integrated transceiver is a system-on-chip that combines a CAN protocol engine and a physical layer transceiver in one device. The protocol controller manages message framing, arbitration, and error handling per the ISO 11898-1 standard, while the transceiver converts digital logic levels to the differential CANH/CANL bus signals per ISO 11898-2. By integrating both blocks, the TCAN4572-Q1 reduces PCB area, BOM count, and host MCU CAN peripheral requirements, placing it within the broader hierarchy of automotive interface IC > CAN interface > CAN FD transceiver/controller > in-vehicle networking IC. Key features include support for classic CAN and CAN FD frames, an SPI interface to the host microcontroller, AEC-Q100 qualification for automotive applications, and SIC (Signal Improvement Capability) for cleaner signal edges on complex topologies. The device operates over a wide supply range suitable for 12V automotive battery rails and includes thermal shutdown, bus dominant time-out, and undervoltage protection. The architecture pairs a dedicated CAN FD controller core with a low-emission differential transceiver. By performing in-situ signal conditioning via SIC, the TCAN4572-Q1 allows designers to deploy CAN FD networks across unshielded cable, mixed topologies, or nodes with significant stub lengths without compromising the bit-time budget. Typical applications include automotive body and chassis ECUs, ADAS sensor networks, battery management system (BMS) communication in electric vehicles, industrial CAN FD gateways, and CAN FD Light systems. The integrated MCU interface simplifies bring-up across zonal architectures where the host processor may lack an on-chip CAN FD peripheral. Designers must evaluate bus topology termination, stub length, and SIC enable/disable timing relative to network jitter budgets. The SPI clock and chip-select routing should be kept short to avoid protocol-controller timing violations during bus error interrupts. This page synthesizes distributor availability, drop-in alternative candidates, and practical design guidance drawn from the Texas Instruments TCAN4572-Q1 datasheet in a single product brief not found on the manufacturer page or distributor listings alone.
TCAN6062-Q1 - CAN XL Transceiver, AEC-Q100, SOIC-8 | TI
The Texas Instruments TCAN6062-Q1 is an automotive-grade, high-speed Controller Area Network (CAN) transceiver that meets the physical layer requirements of the ISO 11898-2:2024 Annex A (CAN XL) specification, housed in an 8-pin SOIC (D) package. Key parameters include CAN XL data-rate support up to 20 Mbps, integrated Signal Improvement Capability (SIC) mode, and PWM decoding on the TXD pin for FAST TX/FAST RX operation. A CAN transceiver is a physical-layer interface IC that converts the differential CAN bus signals (CANH, CANL) into the single-ended TXD/RXD logic levels required by a host microcontroller or CAN controller. It sits in the hierarchy bus transceiver -> bus interface IC -> interface IC -> semiconductor, providing galvanic isolation, level shifting, bus dominant/recessive arbitration, and EMC/ESD protection for the in-vehicle network. Modern CAN XL extends classical CAN and CAN FD by adding a higher data-rate payload channel while preserving backward compatibility with ISO 11898-2. Key features include an integrated standby mode for low-power sleep current, ±8 kV IEC 61000-4-2 ESD protection on the bus pins, ±58 V bus fault protection, and AEC-Q100 Grade 1 qualification (–40 °C to +125 °C ambient). The TCAN6062-Q1 also supports PWM-decoded signaling on TXD, enabling the SIC mode to actively reduce signal ringing during dominant-to-recessive transitions, which is critical for reliable multi-drop CAN XL networks at high data rates. The device architecture pairs a high-speed differential driver/receiver pair with an internal logic core that monitors TXD and decodes PWM-coded commands to switch between normal, FAST TX, FAST RX, SIC, and standby states. Compared with legacy CAN FD transceivers (e.g. TCAN1044A-Q1), the TCAN6062-Q1 adds CAN XL PHY support and the signal-conditioning features required for ISO 11898-2:2024 Annex A compliance, while remaining pin-compatible to 8-pin SOIC footprints used by prior TCAN families. Typical applications include automotive CAN XL backbone and zone-architecture networks, ADAS sensor ECUs (radar, lidar, camera), powertrain and chassis CAN nodes, body-domain controllers, and industrial CAN networks migrating from CAN FD to CAN XL. A key design consideration: ensure the bus termination (typically 120 Ω at each end of the CAN XL backbone, with SIC transceivers often allowing split termination) is sized according to the cable DC resistance and number of in-line stubs. STB pin logic levels must respect the wake/sleep timing in the datasheet to avoid bus contention on cold-start. This page synthesizes manufacturer specifications, distributor availability, AEC-Q100 compliance signals, and same-package cross-reference MPNs (TCAN1044A-Q1, TCAN1472-Q1) into a single engineering reference not duplicated on the TI datasheet alone.

TDA19989BET/C1551 - 150MHz HDMI 1.4 Transmitter | NXP
The NXP TDA19989BET/C1551 is a 150 MHz pixel rate HDMI 1.4 transmitter IC with HDCP 1.3 content protection and CEC support, housed in a 64-ball TFBGA (4.5 x 4.5 mm) package. It accepts parallel digital video (RGB/YCbCr, ITU656) and serializes it for HDMI or DVI output at pixel rates up to 150 MHz. An HDMI transmitter is a video interface IC that converts parallel or digital video bus data into the TMDS (Transition Minimized Differential Signaling) serial stream defined by the HDMI and DVI standards. Within the system hierarchy, it sits in the video signal chain between a graphics source (SoC, FPGA, or video processor) and the physical HDMI connector, and belongs to the broader class of interface ICs and video processing ICs. Key features include the 150 MHz pixel clock supporting 1080p60 video, compliance with CEA-861B, DVI 1.0, and HDMI v1.3a signaling with HDMI 1.4 capability, and integrated HDCP 1.3 cipher engine for protected content. An I2C host interface programs registers, controls the HDCP state machine, and reads EDID from the sink via DDC. CEC support enables consumer electronics control channel communication over the HDMI cable. Architecturally, the TDA19989 family combines input video formatting, TMDS serialization, audio embedding, infoframe generation, and HDCP encryption in a single low-power CMOS die. The 3 x 8-bit video input bus accepts RGB or YCbCr formats, while audio is accepted via I2S or S/PDIF-style inputs and multiplexed into the TMDS stream. Typical applications include set-top boxes, Blu-ray/DVD players, digital media adapters, automotive infotainment head units, and embedded boards with HDMI display outputs. Its compact 4.5 mm BGA suits space-constrained consumer and industrial designs. Designers should note that HDCP license agreements govern use of the cipher, and that the 64-TFBGA requires controlled-impedance TMDS routing on the PCB. Note the part is listed as obsolete by some sources, so verify lifecycle for new designs.

TDA51S-41HC - 5kVrms Isolator w/ DC-DC 150Mbps | MORNSUN
The MORNSUN TDA51S-41HC is a high-performance reinforced digital isolator with an integrated isolated DC-DC converter, providing 5000Vrms isolation, 150Mbps signal rate, and 150kV/us common-mode transient immunity in a 16-pin SOIC-16-300mil (wide-body) package. It operates from -40C to +125C, with a primary-side supply of 3.13V to 3.56V (3.3V nominal) and a secondary-side supply supporting up to 5.5V, and carries a UL1577-based 5000Vrms isolation rating. An isolated data transceiver with an integrated isolated power supply is a device that combines galvanic signal isolation and an on-chip (or on-module) isolated power source in one package. In the power-management hierarchy, it sits above standalone digital isolators, which require a separate isolated DC-DC converter or power module to energize the isolated side. By eliminating that external isolated supply, this device class delivers a complete, small-form-factor isolation solution with fewer components, lower BOM cost, and reduced layout risk. Key features of the TDA51S-41HC include the integrated isolated DC-DC converter, which removes the need for a separate isolated power supply; 150Mbps data rate for high-speed serial links; 150kV/us CMTI for immunity against fast switching transients typical of SiC and IGBT power stages; 5000Vrms reinforced isolation per UL1577; and a wide -40C to +125C industrial operating range. The device provides three forward-direction and one reverse-direction channel, with a fail-safe option: if the input signal is lost, the default output is low for devices with the H suffix, which matches the 41HC suffix in this MPN. The integrated power architecture uses on-chip transformer-based isolation for both signal and power transfer, keeping the total solution footprint small while maintaining reinforced-insulation creepage and clearance in the SOIC-16-300mil wide body. Typical applications include isolated RS-485/fieldbus nodes in industrial automation, isolated power and communication for IGBT/SiC gate-drive circuits, battery management systems, and PLC I/O modules. The combination of signal and power isolation is especially valuable where board space or single-supply constraints make a discrete isolated supply impractical. Design consideration: verify that the integrated DC-DC output power budget covers the isolated-side load; the converter is intended to supply the isolated-side transceiver and light external loads, not full power rails. This page synthesizes distributor data, the MORNSUN datasheet, drop-in family alternatives, and practical design notes not found on the manufacturer product page.
TDA51S485HC - Isolated RS-485 Transceiver 500kbps | MORNSUN
The MORNSUN TDA51S485HC is an isolated, half-duplex enhanced RS-485/RS-422 transceiver with integrated signal isolation, fully compliant with the TIA/EIA-485-A standard, supporting data rates up to 500 kbps in a 16-pin SOIC-16 (300 mil) package. An isolated RS-485 transceiver is a communication interface IC that combines a differential line driver and receiver with galvanic isolation between the logic side and the bus side. Isolation is a critical layer in industrial system hierarchy: within power management and interface electronics, it breaks ground loops, blocks common-mode transients, and protects low-voltage controllers from high-voltage faults on long cable runs in factories and buildings. Key features of the TDA51S485HC include full TIA/EIA-485-A compliance, half-duplex operation on a single twisted pair, data transmission up to 500 kbps, and an integrated fail-safe circuit. The fail-safe function guarantees a defined receiver output state when the bus is idle, shorted, or open, eliminating false characters caused by undriven bus conditions - a common problem in legacy RS-485 networks that otherwise requires external bias resistors. The enhanced transceiver architecture integrates the isolation barrier in a compact SOIC-16-300mil body, reducing board area compared to discrete optocoupler-plus-transceiver designs. It is engineered for harsh industrial environments where robust differential signaling, noise immunity, and long-distance communication over twisted-pair cable are required. Typical applications include industrial automation and PLC networks, building control and HVAC systems, motor control and inverter communication buses, energy metering, and security or access-control systems that communicate over RS-485 fieldbus segments. A key design consideration is bus termination and biasing: even with the internal fail-safe circuit, verify that your network topology, node count, and cable length remain within RS-485 loading and 500 kbps timing budgets; add 120-ohm termination at both cable ends for long runs. This page synthesizes distributor pricing, stock data, drop-in alternative information, and practical design notes not found in the manufacturer datasheet alone.
TDA51SCANHC - 5kV Isolated CAN Transceiver 1Mbps | MORNSUN
The MORNSUN TDA51SCANHC is an isolated CAN bus transceiver module with an integrated 5 V isolated power supply, compliant with the ISO11898-2 standard, capable of data rates up to 1 Mbps in a 16-pin SOIC (SOIC-16-300mil, 7.50 mm width) package. An isolated CAN transceiver is an interface IC that provides galvanic isolation between a CAN protocol controller and the physical two-wire CAN bus. Isolation breaks ground loops, protects low-voltage circuitry from common-mode transients, and is essential where nodes span large ground potential differences. Within the signal-chain hierarchy, the TDA51SCANHC belongs to the isolated interface family: transceiver -> bus transceiver -> isolated CAN transceiver -> isolation and interface module. Key features include 5000 VDC galvanic isolation, a common-mode transient immunity of 150 kV/us, and an integrated, efficient 5 V isolated power output that eliminates the need for a separate isolated DC-DC converter on the bus side. The device provides differential transmit and receive capability between the CANH/CANL physical bus and the protocol controller, and it operates across the full -40C to +125C industrial-extended temperature range. A notable protection feature is the TXD dominant time-out function: if a hardware or software fault forces the TXD pin permanently low, the built-in dominant time-out timer prevents the bus from being blocked in a permanent dominant state, safeguarding network availability. Typical applications include industrial fieldbus nodes (Profibus/CANopen gateways), battery management systems, motor-drive control networks, building automation, and medical equipment where isolation between the controller domain and the bus is mandated by safety or robustness requirements. Design consideration: because the part integrates an isolated 5 V power stage, PCB layout must respect the creepage and clearance distances across the isolation barrier defined for the SOIC-16-300mil package, and the integrated power output should be decoupled per the manufacturer datasheet recommendations. This page synthesizes distributor pricing, availability data, family drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
TDA8029HL/C207 - Smart Card Reader IC, 5V, LQFP-32 | NXP
The NXP TDA8029HL/C207 is a complete single-chip, low-power, low-cost, robust smart card reader IC supplied in a 32-pin LQFP (7x7 mm) package. It supports ISO 7816-3 and EMV 4.x smart cards and integrates a DC-DC converter capable of operating from a wide supply range, plus a precision card-supply supervisor with spike-killing and power-on reset. The device targets portable POS terminals, set-top box conditional-access modules, identification readers, and SIM/SAM interface designs. Key specifications include operation from a 3 V to 6 V host supply (with 5 V tolerance on the host interface), an on-chip DC-DC converter that can be configured as a doubler, tripler, or follower to generate the card VCC (typically 1.8 V, 3 V or 5 V), card-clock division ratios from 1 to 16, support for synchronous cards (up to 10.8 ETU for the C207 variant), and ISO UART handling with automatic CRCI/LRC computation on T=0 and T=1 protocols. A smart card interface IC (also called a contact smart card reader or ISO 7816 interface) sits between a host microcontroller and a contact-based smart card, providing level shifting, ESD protection, card-presence detection, clock generation and data framing. The TDA8029 family belongs to NXP's smart-card interface portfolio and is widely used in payment terminals, government/eID readers and telecom SIM sockets, forming a dedicated bridge between the secure card world and a general-purpose MCU. The architecture combines an 8-bit parallel host interface with internal FIFOs, on-chip voltage generation and supervision, and dedicated active-low card detect / CMDVKO logic so that the host MCU only has to issue high-level commands. Compared to discrete implementations built from a LDO plus discrete transceivers, the TDA8029HL integrates protection, signal-conditioning and the entire ISO 7816 protocol engine on one die, reducing BOM count and PCB area for compact portable readers. Typical applications include EMV contactless/contact payment terminals, government and healthcare eID document readers, set-top box conditional-access smart cards, USB token readers and PC-linked reader dongles, and industrial access-control terminals. The wide supply range and low standby current make it particularly attractive for battery-powered handheld POS. Designers should pay attention to the decoupling network on the card side (typically 100 nF + 220 nF) and to the chosen step-up/step-down topology - the C207 variant supports synchronous card timing at 10.8 ETU which is mandatory for some payment cards. The host-side software must drive the dedicated power-down mode to achieve the lowest quiescent current when no card is present. This page synthesises authoritative datasheet data, current distributor pricing, drop-in part numbers within the TDA8029 family and cross-vendor equivalents, plus practical design notes that go beyond the manufacturer datasheet alone.
TDC1000QPWRQ1 - Automotive Ultrasonic AFE | Texas Instruments

An ultrasonic sensing analog front end is a specialized integrated circuit that interfaces between a microcontroller and an ultrasonic transducer. It generates the excitation pulses to drive the transducer, amplifies the returning echo signal, and converts the time-of-flight into a digital value. This enables precise distance, level, or flow measurements. The TDC1000-Q1 belongs to the family of ultrasonic sensing AFEs, which are part of the broader category of sensor signal conditioning ICs within the analog front end product group. Key features of the TDC1000QPWRQ1 include a programmable transmit frequency up to 1 MHz, a receive amplifier with adjustable gain, and a time-to-digital converter with a resolution of 10 ps. It supports multiple transducer configurations and includes an internal temperature sensor for compensation. The device is AEC-Q100 qualified for automotive applications, ensuring reliability under extreme conditions. Technically, the TDC1000-Q1 uses a time-to-digital conversion architecture that measures the round-trip time of an ultrasonic pulse. This approach provides high accuracy and immunity to amplitude variations. The device includes a low-noise amplifier (LNA) with a programmable gain range, a band-pass filter, and a comparator to detect the echo. The digital output is a 16-bit time measurement that can be read via an SPI interface. Typical applications include automotive fuel level sensing, washer fluid level detection, and industrial tank level monitoring. The device is also used in concentration sensing for urea or diesel exhaust fluid (DEF) in vehicles. Its automotive qualification and wide temperature range make it ideal for under-hood and chassis-mounted sensors. When designing with the TDC1000QPWRQ1, ensure proper decoupling of the power supply and careful layout of the transducer connections to minimize noise. The SPI interface should be isolated from high-current traces to avoid interference. Refer to the TIDA-00322 reference design for a complete automotive ultrasonic fluid level sensing solution.
THS6052CD - 175mA ±12V ADSL CPE Line Driver | TI
The Texas Instruments THS6052CD is a 175 mA, ±12 V ADSL CPE and PLC line driver integrated circuit in an 8-SOIC package. It is designed for full-rate ADSL and G.Lite applications, with a noninverting current-noise density of 2.7 pA/√Hz and a wide supply-voltage range suitable for dual-polarity line-driver circuits. The device provides two driver outputs, supports operation from a 1:1 transformer ratio, and is intended for customer-premises equipment, splitters, and other high-current telephone-line interface applications. An ADSL line driver is a specialized interface amplifier that converts a low-level transmit signal into the voltage and current levels required by a copper telephone line. The THS6052CD belongs to the interface-IC and line-driver hierarchy, combining signal conditioning with the drive capability needed to overcome line attenuation and transformer losses. Its ±12 V operating capability also makes it suitable for bipolar line interfaces where a single positive supply would not provide adequate output swing. The main feature of the THS6052CD is its combination of high output current, low current noise, and a wide supply range. The 175 mA output-current capability provides margin for driving the line through transformer windings and termination networks. The 2.7 pA/√Hz noninverting current-noise specification helps preserve signal integrity when the driver is used in sensitive transmit paths. A wide operating supply range supports both conventional ADSL equipment and power-line-related line-driver circuits. The THS6052CD uses an 8-SOIC package, which is a surface-mount package in the SOIC family. The device is specified for 0 to 70 °C operation in the distributor data supplied for the THS6052CD. Its architecture is intended for high-current line driving rather than general-purpose low-power signal conditioning, so the external transformer, termination, protection, and biasing network must be designed around the specified output-current and supply-voltage limits. Typical applications include ADSL customer-premises equipment, G.Lite modems, DSL line-interface networks, telephone-line splitters, and PLC-style line-driver interfaces. In these systems, the THS6052CD is placed between the upstream transmit signal path and the line transformer, with local feedback used to establish the required drive level and bandwidth. The device can reduce the number of external drive components when its current capability and noise performance match the transformer and network requirements. Designers should pay particular attention to supply bypassing, transformer selection, output-current margin, and protection against transient events on the telephone line. The SOIC package also requires careful thermal assessment when operating continuously near the 175 mA output-current capability. The available verified information does not provide a complete pinout table, detailed timing characteristics, or a complete set of quantitative electrical limits, so those values are identified in the specification fields as data needed for final design sign-off. This page combines the verified Texas Instruments product identity, distributor package and pricing information, relevant source links, and engineering-oriented selection guidance. It is intended to help engineers identify whether the THS6052CD matches the required ADSL line-driver application before downloading the official manufacturer datasheet and completing detailed circuit validation.
THS6053ID - 175mA Dual ADSL Line Driver | Texas Instruments
The Texas Instruments THS6053ID is a dual high-speed DSL line driver designed for ADSL customer-premises-equipment and power-line communications. It provides two output channels, each capable of sourcing 175 mA, and operates from a 5 V to 15 V supply in a 14-pin SOIC package. The device is intended for dual ±12 V operation, with 5.2 mA of supply current per channel and a shutdown function for reducing power consumption when the line driver is not needed. A DSL line driver is an interface integrated circuit that converts a low-voltage logic signal into a high-current, low-voltage differential signal suitable for transmission over a twisted pair. Within the signal-chain hierarchy, the THS6053ID is a line driver within the broader category of interface ICs, bridging digital logic and telephone-line or power-line networks. Its 175 mA output capability provides the current needed to drive a 1:1 ratio isolation transformer and a line termination network. The THS6053ID supports both full-rate ADSL and G.Lite applications. A documented current-noise density of 2.7 pA/√Hz is particularly useful in this environment because it limits the broadband noise coupled into the hybrid and the downstream channel. Wide supply-voltage tolerance permits operation from single-ended rails or from split ±12 V supplies, while the shutdown input supports power-management strategies in multichannel CPE equipment. The device provides two line drivers and no receivers. Its key design consideration is that the line-driver outputs must remain compatible with the external transformer, termination, protection, and filtering network. Output-current headroom and thermal dissipation should be checked against the selected transformer and cable length rather than inferred only from the nominal 175 mA rating. Typical uses include ADSL CPE line interfaces, PLC modems, splitter and filter assemblies, and other high-speed DSL or line-driver subsystems. This page also consolidates verified pricing, same-package alternatives, pin and application guidance, and comparison information that is not presented together in a single manufacturer document.
