TCA9554PWR

TCA9554PWR - 8-Bit I2C I/O Expander | Texas Instruments

Texas Instruments TCA9554PWR is an 8-bit I2C and SMBus I/O expander with an interrupt output and configuration registers, designed for low-voltage systems operating from 1.65 V to 5.5 V. It adds eight general-purpose parallel I/O lines to a host microcontroller through the two-wire I2C bus and is supplied in a 16-pin TSSOP package. The device supports I2C communication up to 400 kHz and includes hardware-selectable A0, A1, and A2 address pins, allowing up to eight devices on one bus. An I/O expander is an interface IC used to extend the number of digital input and output lines available to a microcontroller or processor. The TCA9554 belongs to the I2C interface family within the broader interface-controller and power-management-system hierarchy. It is useful when a system needs additional control signals, status inputs, LEDs, relays, or switch sensing without allocating direct host-controller pins. Key features include eight configurable I/O ports, an interrupt output for input-state changes, weak pull-up configuration registers, and a power-on reset that restores the default device state when the supply is cycled. The 1.65 V to 5.5 V operating range supports low-voltage embedded systems, while the 400 kHz bus capability allows relatively fast host-to-expander communication. The device also provides separate register-based control for input and output ports. The TCA9554 uses the I2C or SMBus-compatible serial interface for register access and parallel port data transfer. Its address pins provide hardware configuration, reducing firmware complexity when several expanders share a bus. The interrupt output allows the host to remain in a low-power state until an input changes, rather than polling all eight inputs continuously. The interrupt behavior and configurable pull-up functions make the device useful for both active control and monitored input designs. Typical applications include Arduino-compatible boards, ESP32 systems, industrial control panels, LED and relay interfaces, keypad or switch monitoring, home-automation controllers, and compact embedded instruments. In an ESP32 design, the expander can provide eight additional lines for sensors, indicators, or actuators while preserving the host processor resources for communication and control. Designers should route I2C traces away from noisy switching nodes, confirm address assignments before software configuration, and account for open-drain bus pull-up requirements. The manufacturer datasheet is the authoritative reference for pin assignments, register behavior, electrical limits, and timing values. Use the device when a low-voltage, interrupt-capable, eight-line expansion function fits the system architecture. This page consolidates the manufacturer product information, ordering details, technical comparisons, and practical implementation guidance for engineers evaluating TCA9554PWR in embedded and industrial designs.

TCA9555DBR - 16-Bit I/O Expander | Texas Instruments
TCA9555DBR

TCA9555DBR - 16-Bit I/O Expander | Texas Instruments

The Texas Instruments TCA9555DBR is a 16-bit I2C and SMBus I/O expander operating from a 1.65 V to 5.5 V supply, with an I2C bus speed up to 400 kHz. It is packaged in a 24-pin SSOP (DB) package and is intended for -40°C to +85°C industrial operation. The device adds 16 configurable digital input or output ports while conserving limited microcontroller GPIO pins. An I2C I/O expander is an interface IC that converts a serial two-wire bus connection into multiple parallel digital ports. Its place in the hierarchy is interface IC, then bus interface and port expander, then semiconductor. This expansion function is useful when a system needs more control or status signals than the host microcontroller can expose directly. The TCA9555DBR also supports SMBus-style communication, interrupt signaling, configuration registers, and weak pull-ups. Key features include 16 independently configurable I/O bits, a 1.65 V minimum operating supply, a 5.5 V maximum operating supply, and a maximum stated bus frequency of 400 kHz. An interrupt output lets the connected processor respond to a change at one of the external ports without continuous polling. Configuration registers allow the port direction and operating state to be established through the serial interface, reducing the number of dedicated GPIO pins required by the host controller. The weak pull-up characteristic supports systems in which external resistors are used for the I2C bus. The external bus determines the final pull-up strength and should be selected with the complete bus capacitance and voltage level in mind. Because the TCA9555DBR operates from the same low-voltage range used by common embedded processors, it can simplify power-domain design when the host operates at 1.8 V, 2.5 V, 3.3 V, or 5 V. Typical applications include industrial control panels, sensor-hub boards, programmable logic controllers, test equipment, and compact embedded systems that need additional digital lines. In a sensor-hub design, inputs can monitor switches or fault flags while outputs can control enables or indicators. The interrupt line reduces processor activity when multiple distributed inputs must be monitored. The primary design consideration is I2C address allocation. If several expanders share one bus, address-select pins and hardware straps must produce unique addresses without creating excessive leakage or bus loading. The 400 kHz bus limit must also be respected when longer cables, higher capacitance, or additional peripherals are present. This product page combines the manufacturer’s interface specifications with practical application guidance, package information, and a focused comparison of documented alternatives. It highlights where the TCA9555DBR fits and where engineers should verify address behavior, electrical timing, and device-specific functions before approving a substitution.

TCA9555DBT - 16-Bit I/O Expander | Texas Instruments

The Texas Instruments TCA9555DBT is a 16-bit I2C and SMBus I/O expander with interrupt output, configuration registers, and weak pull-ups, designed for 1.65 V to 5.5 V operation in a 24-pin SSOP package. The device supports bus frequencies up to 400 kHz and provides eight programmable addresses according to the Texas Instruments product documentation. An I/O expander is an interface IC that increases the number of digital input and output pins available to a host controller. It connects through a two-wire I2C or SMBus interface and reduces the number of general-purpose pins required on a microcontroller, processor, or programmable logic device. The TCA9555 belongs to the interface-controller hierarchy, where I2C/SMBus expansion reduces interconnect complexity while preserving digital control over attached peripherals. The TCA9555 provides 16 I/O lines, an interrupt output, configuration registers, and weak pull-up capability. According to the Texas Instruments product page, it operates from 1.65 V to 5.5 V and supports I2C/SMBus communication at up to 400 kHz. Its configurable I/O architecture allows a system designer to group external lines into input, output, or mixed operating arrangements and to read their states through the serial interface. The interrupt output provides a hardware indication that a change has occurred on an input, allowing the connected controller to respond without continuous polling. Configuration registers define the direction of each I/O line, while the optional weak pull-ups can support open-drain-style bus arrangements when external pull-ups are not present. These features make the device useful when a design needs more control lines than the host device can expose directly. Typical uses include low-voltage embedded control, display interfaces, key matrices, relay and sensor interfaces, and general-purpose I/O expansion. The 1.65 V minimum supply voltage also supports systems operating below conventional 3.3 V and 5 V logic levels, although every connected I2C device must use a compatible voltage range and the I/O levels must be checked against the system requirements. For implementation, connect the supply and ground pins to the same appropriate voltage domain, route the I2C clock and data lines to the host bus, and place pull-up resistors where the bus requires them. Use the configuration registers to establish input or output direction before driving an output. Treat the weak pull-ups as a limited auxiliary feature rather than a substitute for correctly sized external bus pull-ups. This page consolidates the device's principal interface, voltage, frequency, addressing, and package characteristics with engineering guidance for layout, firmware, and component selection. It also distinguishes verified drop-in replacements from devices that merely perform a similar function, helping engineers preserve footprint and pin compatibility during sourcing and design reviews.

TCA9555PWR

TCA9555PWR - 16-bit I2C/SMBus I/O Expander w/ Interrupt | TI

The Texas Instruments TCA9555PWR is a 16-bit I2C/SMBus I/O expander with interrupt output and configuration registers, operating from 1.65 V to 5.5 V VCC and housed in a 24-pin TSSOP (PW) package. It provides remote 16-bit general-purpose parallel I/O expansion through the two-line bidirectional I2C bus and supports SMBus signaling up to 400 kHz in the TI variant (with 1 MHz capability in the UMW second-source marking). The device integrates three hardware address pins (A0/A1/A2), an open-drain active-low INT output, and per-port weak pull-up resistors that can be enabled via the configuration register. An I2C I/O expander is a category of bus-interface IC that allows a host microcontroller with limited native GPIO to gain additional digital inputs or outputs over a two-wire serial bus. The taxonomy is: I/O expander -> parallel I/O -> digital interface IC -> interface IC -> integrated circuit. The TCA9555 belongs to the second-generation TI family characterized by wider VCC range (down to 1.65 V), higher SMBus speed, lower standby current, and the addition of weak pull-ups. It is widely used to recover GPIO budget on small-pin-count MCUs, add level-translated interfaces, and aggregate slow peripherals such as keypads, LEDs, or push-buttons. Key features of the TCA9555PWR include 16 individually configurable I/O bits, 5 V tolerant I/O ports, 25 mA sink/source per bit (with total package limits), an active-low interrupt line that fires on any input state change, and three programmable I2C address pins supporting up to eight devices on the same bus (64 I/O total). The internal power-on reset brings all I/O to inputs and clears the configuration, polarity-inversion, and mask registers to defaults, eliminating spurious writes at startup. The architecture is a CMOS parallel expansion core driven by a finite state machine on the I2C/SMBus interface. Writes go through a write-protection check and into 8-bit configuration, polarity, and output registers; reads decode the input and output registers with optional polarity inversion. Hardware behavior is fully static and register-mapped, so no clock is required externally. Typical applications include MCU GPIO expansion in industrial control panels, signal aggregation in telecom baseband cards, keypad/LED scanning, and portable consumer devices such as e-readers where any-pin-as-input is needed for button wake events. A representative circuit places the TCA9555PWR on the host's I2C bus with 4.7 kohm pull-ups on SDA/SCL, bypassed VCC, and optional 10 kohm pull-ups on the interrupt and reset pins. INT can be wired to the MCU's edge-sensitive external interrupt so the host wakes only when an input state changes, saving overall system power. When designing with this device, confirm VCC level compatibility - the 1.65 V lower bound matches low-voltage MCUs, but the host and the device must share a common reference. Allow total DC current budget per bank and per package; aggregate sink/source must be derated for high-bit-count use. Use the configuration register to enable or disable weak pull-ups based on the external pull-up strength present on the line.

TCA9617BDGKR - 1MHz FM+ I2C Bus Repeater, VSSOP-8 | Texas Instruments
TCA9617BDGKR

TCA9617BDGKR - 1MHz FM+ I2C Bus Repeater, VSSOP-8 | Texas Instruments

The Texas Instruments TCA9617BDGKR is a 2-bit bidirectional I2C/SMBus buffer and repeater that performs voltage level translation between mixed-voltage buses in a single 8-pin VSSOP (DGK) package. It supports I2C Standard-mode, Fast-mode, and Fast-mode Plus (Fm+) operation up to 1 MHz, and translates bidirectionally between a low-voltage A-side bus (0.8 V to 5.5 V) and a high-voltage B-side bus (2.2 V to 5.5 V), enabling seamless interconnect between legacy 3.3 V/5 V microcontrollers and modern low-voltage processors operating at 1.0 V, 1.2 V, or 1.8 V rails. An I2C bus repeater is a specialized bus interface device that electrically isolates two physical I2C segments while still allowing them to behave as one logical bus. By buffering the SCL and SDA lines, a repeater overcomes the classic I2C limitation of bus capacitance: each segment of the bus is loaded independently, so engineers can attach far more devices, run longer PCB traces, or use longer cables than would otherwise be possible. The TCA9617B also performs voltage level translation (also called a level shifter), so the same repeater allows a low-voltage MCU to talk to a 5 V sensor without dedicated glue logic. Key specifications of the TCA9617BDGKR include: 1 MHz maximum clock frequency, support for 0.8 V to 5.5 V on the A-side, 2.2 V to 5.5 V on the B-side, EN (enable) input with powered-off high-impedance behavior, low standby current (VCCA suspend), and integrated pull-up current sources that eliminate the need for external bus pull-ups on the B-side. The BiCMOS internal design provides clean edges and controlled rise/fall times even at full Fm+ speed. The device is offered in three temperature grades with -40 °C to +85 °C as the commercial grade. Typical applications include I2C bus extension between boards, voltage translation between low-voltage MCUs and 3.3 V/5 V peripherals, server backplanes, telecommunications equipment, and any system where the total bus capacitance exceeds the 400 pF Fast-mode or 550 pF Fast-mode Plus limit imposed by the I2C specification. The repeater transparently regenerates SCL and SDA so that slaves on either side see a clean, well-formed waveform. When designing with the TCA9617B, observe that the A-side and B-side each require their own pull-up resistors; the B-side pull-ups must be to VCCB and the A-side pull-ups must be to VCCA. Avoid enabling the device with EN high before both VCCA and VCCB rails have ramped. Series resistance on the bus should be kept low to preserve Fm+ rise-time margins. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, providing a single reference for engineers selecting an I2C repeater/level shifter for mixed-voltage systems.

TCA965B - Window Comparator, 4.5-30 V, 14-DIP | Infineon
TCA965B

TCA965B - Window Comparator, 4.5-30 V, 14-DIP | Infineon

The Infineon Technologies TCA965B is a bipolar window discriminator with two adjustable window settings, adjustable hysteresis, and two open-collector digital outputs rated for 50 mA. Its verified supply range is 4.5 V to 30 V, and the specified commercial package is the 14-pin PG-DIP-14-1 through-hole package. The device indicates whether an input voltage is below, inside, or above a defined comparison window. A window comparator is a specialized comparator integrated within the broader voltage-comparator and analog-interface hierarchy. Instead of providing only one switching threshold, it evaluates an input against two limits and reports when that input lies outside the acceptable band. This makes the TCA965B useful for voltage supervision, tracking control, dead-band control, and DC-voltage selection tasks identified in the manufacturer documentation. The window edges can be configured directly, or the window can be established indirectly from its center voltage and half-width. Adjustable hysteresis reduces output chatter when the monitored voltage changes near an edge, while an adjustable reference supports threshold calibration. The open-collector outputs permit wired logic, relay interfaces, and pulled-up buses, but external pull-up resistors and suitable sink-current limits are required. The bipolar implementation supports operation from 4.5 V through 30 V, making the TCA965B appropriate for industrial control systems operating above conventional low-voltage logic rails. Because its outputs are open collector, the device can interface with systems whose logic supply differs from the comparator supply. Designers must account for output rise time, pull-up resistance, load capacitance, and the common-emitter arrangement when wiring the outputs. Typical uses include power-supply sequencing, battery-voltage qualification, tracking power controllers, process-control dead-band monitors, and DC-voltage selection within an allowed tolerance. In each circuit, the two window references determine acceptance limits while the digital outputs report undervoltage, in-window, and overvoltage conditions. The principal tradeoff is that the legacy 14-DIP package is larger than modern surface-mount alternatives, but it supports straightforward prototyping and through-hole assembly. When designing around the TCA965B, begin with the verified supply requirement, configure the reference and window network using the manufacturer guidance, and confirm every output pull-up voltage. Do not assume logic-level compatibility from the 30 V supply capability because the open-collector pins do not actively drive a high output. Check hysteresis against noise and load-transient requirements, then validate the complete threshold system across temperature and supply variation. This page combines the verified manufacturer and distributor records with package, application, comparison, and design guidance. It also distinguishes verified facts from unavailable electrical details rather than estimating unstated thresholds, propagation delays, package dimensions, or prices.

The device meets the requirements of ISO 11898-2 for automotive CAN, providing robust communication with a 1/1 driver/receiver configuration and half-duplex operation. Technically, TCAN1042GVDRQ1 integrates a differential driver and receiver, providing differential transmit and receive capability. The I/O level shifting feature allows direct connection to microcontrollers with lower logic levels, eliminating the need for external level translators. Fault protection safeguards the device and bus against short circuits, thermal stress, and voltage surges, ensuring reliable communication in noisy environments. Typical applications include automotive body control modules, gateways, battery management systems, industrial automation, and medical devices where reliable CAN communication is required. The wide operating temperature range and AEC-Q100 qualification (implied by automotive designation) make it suitable for under-hood and harsh environment deployments. During design, ensure proper decoupling capacitors (100 nF and 10 uF) are placed close to the VCC pin to minimize noise, and use the appropriate bus termination resistors (120 ohms) at both ends of the bus. The SOIC-8 package allows compact PCB layouts, but thermal management should be considered for high-temperature environments.

The device is intended for automotive and industrial networks requiring robust bus fault handling. A CAN transceiver is the physical-layer interface between a CAN controller and a differential CAN bus. It converts logic-level TXD and RXD signals into CAN bus levels and back again. Within the hierarchy of automotive communication ICs, a CAN transceiver is a network interface transceiver, a bus-interface IC, and ultimately a semiconductor. Fault protection adds the ability to survive specified bus faults without permanent damage. The TCAN1042HD provides classic CAN operation together with CAN FD support up to 2 Mbps. Its single-driver, single-receiver organization is suitable for a conventional CAN node rather than a multi-node bus interface. The 4.5 V to 5.5 V supply range supports regulated 5 V systems, while the -55°C to +125°C rating covers demanding automotive temperature ranges. Its 8-pin SOIC package supports conventional surface-mount assembly. The transceiver provides a defined interface between a CAN controller and the differential CANH and CANL conductors. The TXD input accepts controller-generated logic, while RXD presents a logic-level receive signal to the controller. Fault-protected operation is important when the bus may be exposed to short circuits, abnormal voltage conditions, or other faults. ISO 11898-2:2016 physical-layer compliance is specifically identified for this device family. Typical uses include automotive body and powertrain electronics, industrial automation controllers, robotics, building automation, and embedded CAN gateways. A controller such as a CAN FD-capable microcontroller can use the TCAN1042HD for the physical network connection, while external bus protection and filtering may be added where the cable length, topology, or electromagnetic environment requires it. PCB design should keep the CANH and CANL route as a closely coupled differential pair and minimize the area between their return paths. Place transceiver and termination components near the connector or bus-entry point, observe the manufacturer’s grounding and supply-decoupling recommendations, and verify that the controller interface voltage levels match the transceiver logic requirements. This product page combines the device specifications, package and lifecycle information, sourcing workflow, same-family drop-in alternatives, and practical CAN-interface design guidance. It is intended to help engineers identify the correct device and plan a robust PCB implementation without relying solely on a basic distributor listing.

It supports both classical CAN and CAN FD (Flexible Data-Rate) networks at data rates up to 8 megabits per second (Mbps), and ships in an 8-pin SOIC (DRB) package with an operating temperature range of -40 C to +125 C. A CAN transceiver is a physical-layer interface IC that bridges a digital CAN protocol controller (typically embedded in a microcontroller) to a differential two-wire CAN bus. The transceiver translates the controller's single-ended TXD/RXD logic signals to the bus's dominant/recessive differential signaling required by ISO 11898-2, while providing bus-side ESD protection, common-mode range, and dominant-time-out fault protection. The TCAN1044-Q1 family sits in the CAN interface IC -> interface IC -> integrated circuit hierarchy and is a foundational building block for in-vehicle networks (IVN). Key features include 8 Mbps CAN FD data-rate support for next-generation vehicle networks, IEC 61000-4-2 ESD protection on bus pins, low-loop delay for propagation-tight networks, and a low-power standby mode with a remote-wake-up wake request via the bus (per the TCAN1044 family datasheet). The device operates from a single 4.5 V to 5.5 V VCC supply, draws typically 50 mA in normal mode, and integrates thermal shutdown plus bus-dominant time-out to prevent network lockup. The TCAN1044DRQ1 architecture uses a high-speed differential driver and a wide-common-mode receiver that exceeds the -2 V to +7 V common-mode range required by ISO 11898-2:2016. Internal level shifting on TXD/RXD allows direct connection to 3.3 V or 5 V microcontrollers without external logic-level translators, and the integrated bus fault protection tolerates -58 V to +58 V transients common in automotive 12 V/24 V systems. Typical applications include automotive body and chassis CAN nodes (BCM, gateway modules), CAN FD powertrain networks, industrial CAN-bus field-bus nodes, and electric-vehicle battery management system (BMS) master/slave communication. The AEC-Q100 Grade 1 qualification makes it appropriate for under-hood and safety-critical vehicle ECUs. When designing with this part, observe the 60 ohm bus termination requirement of ISO 11898-2 and place a 100 nF VCC decoupling capacitor within 2 mm of the supply pin. Avoid routing the CANH/CANL differential pair over splits in reference planes, and use a 120 ohm characteristic-impedance cable/trace geometry.

It meets ISO 11898-2:2016 for high-speed CAN and ISO 11898-5:2007 for CAN FD physical-layer behavior. These standards define the physical signaling, timing, and fault-handling expectations used by compatible CAN controllers and network equipment. Typical applications include industrial automation controllers, electric-vehicle and vehicle-control modules, robot communication networks, building automation gateways, diagnostic interfaces, and embedded industrial computers. In each case, the transceiver sits between a CAN controller and the differential bus while isolating the controller from the physical CANH and CANL network. Bus termination, common-mode filtering, protection components, and decoupling must be implemented according to the manufacturer data sheet. For PCB design, place the transceiver close to the connector or bus interface to minimize trace area on CANH and CANL. Use a symmetrical pair routing, controlled return-current paths, and the recommended power and ground decoupling. Keep sensitive logic and analog circuitry away from high-energy bus connections, and verify the selected transceiver's sleep-state, enable, and logic-level behavior against the host controller. This product page combines device specifications, standards coverage, engineering application guidance, and drop-in replacement analysis. It is intended to support component selection, PCB planning, and qualification decisions without substituting a new footprint or changing the installed eight-pin SOIC land pattern.

TCAN1145DRQ1 - Automotive CAN FD Transceiver | Texas Instruments

The Texas Instruments TCAN1145DRQ1 is an automotive CAN FD transceiver with selective wake and SPI-configurable operation, supporting data rates up to 5 Mbps and processor I/O voltages from 1.8 V to 5 V in a 14-pin SOIC package. It is designed for high-speed CAN networks that need enhanced data rates, reduced-node sleep operation, and controlled low-power wake behavior. A CAN transceiver is the physical-layer interface between a host processor and a Controller Area Network bus. The TCAN1145-Q1 family supports enhanced high-speed CAN FD and high-speed CAN operation, while its selective-wake function uses wake-up frame identification to reduce the number of active network nodes. Its SPI interface provides access to device configuration and status functions, allowing a microcontroller to manage transceiver behavior without relying on undisclosed control assumptions. The principal verified feature set includes support for CAN FD data rates up to 5 Mbps, nominal processor I/O operation from 1.8 V to 5 V, and selective wake for partial networking. The TCAN1145DRQ1 ordering variant is identified by DigiKey as a 1/1 half-CANbus transceiver in a 14-SOIC package. The TI product description also associates the device with automotive CAN FD applications and ISO 11898-2:2016-compatible selective-wake functionality. The device is intended for vehicle body, comfort, infotainment, gateway, and distributed control networks where sleeping nodes must be awakened selectively. Compared with a conventional always-on CAN transceiver, the selective-wake architecture can reduce activity in a partial network and preserve energy when only selected nodes communicate. The SPI interface also supports firmware-controlled configuration, which is useful when a system needs programmable bus-management behavior. Designers should confirm the complete electrical limits, pin functions, transceiver modes, ESD behavior, loopback behavior, and timing values from the manufacturer datasheet before layout release. CAN bus routing requires controlled differential impedance, appropriate termination, common-mode protection according to the vehicle design, and careful separation from noisy high-current paths. The transceiver should be placed near the connector and bus protection network, while SPI and ground returns should be routed away from the CANH and CANL conductors. TCAN1145DRQ1 is best suited to new automotive electronic systems that specifically need CAN FD, selective wake, SPI access, and a 1.8 V to 5 V processor interface. The TCAN1042HGDR comparison reference is useful for evaluating a different TI CAN transceiver, but it should not be treated as a drop-in replacement without confirming its pinout and electrical requirements.

TCAN1472-Q1 - Automotive CAN SIC Transceiver, 8Mbps, 8-SOIC | TI
TCAN1472-Q1

TCAN1472-Q1 - Automotive CAN SIC Transceiver, 8Mbps, 8-SOIC | TI

The Texas Instruments TCAN1472-Q1 is an automotive-grade, fault-protected CAN FD transceiver with Signal Improvement Capability (SIC) that supports classical CAN and CAN FD up to 8 Mbps, available in an 8-pin SOIC (D) package with industry-standard pin-out. It is qualified to AEC-Q100, listed as Functional Safety-Capable, and is designed to meet the physical-layer requirements of ISO 11898-2:2024 Annex A (CAN SIC). A CAN (Controller Area Network) transceiver is the physical-layer interface between a CAN protocol controller (typically an MCU or ASIC) and the differential CAN bus wiring. It converts the controller's TX/RX logic-level signals to the bus's dominant/recessive differential voltages and adds bus-side protection, fault detection, and EMC filtering. SIC is an optional extension layer that actively reshapes the bus waveform to reduce ringing on long stubs and high-speed topologies, allowing faster bit rates (up to 8 Mbps with CAN FD) on networks that previously had to slow down for signal integrity reasons. Key features of the TCAN1472-Q1 include: support for classical CAN and CAN FD up to 8 Mbps with active SIC; ±58 V (typ.) fault-protected CAN bus pins; IEC 61000-4-2 ESD rating of ±8 kV contact / ±15 kV air on bus pins; low-current standby mode with remote wake-up via bus; and an operating voltage range of 4.5 V to 28 V (load-dump tolerant up to 40 V). 'V'-suffix variants (e.g. TCAN1472VDRQ1, TCAN1472VDFFRQ1) include a VIO logic-level supply pin so the device can interface directly with 1.8 V / 2.5 V / 3.3 V MCUs without external level shifters. The device integrates a 3.3 V / 5 V tolerant reference output, thermal shutdown, driver-dominant time-out, and under-voltage lockout on both VCC and VIO. Its bus-side hardware meets ISO 11898-2:2024 Annex A (SIC), ISO 11898-2:2016, and SAE J2284, making it drop-in compatible with existing 8-pin CAN FD footprints such as TCAN1042-Q1 and TCAN1044A-Q1 while adding the SIC waveform improvement stage. Typical applications include automotive body and chassis ECUs (BCM, gateway, HVAC, lighting), ADAS sensor fusion ECUs, xEV battery-management and powertrain controllers, industrial CAN networks with long stub lengths, and any automotive CAN FD node that needs to coexist with classical CAN on the same bus. The wide supply range also makes the part well suited for 12 V and 24 V truck and off-road CAN bus systems. When designing with the TCAN1472-Q1, place a 100 nF decoupling capacitor as close as possible to VCC and (on V-suffix parts) VIO, and a 4.7 µF or larger bulk capacitor on the bus-side CAN supply. On long-stub networks, leave SIC enabled to suppress reflections; on point-to-point links SIC can be turned off for the lowest loop delay. Always verify that the chosen package thermal pad layout matches the 8-pin SOIC land pattern.

TCAN330D - 3.3V 1Mbps CAN Transceiver | Texas Instruments

Texas Instruments TCAN330D is a 3.3-V, one-half CAN bus transceiver with a maximum specified data rate of 1 Mbps, ISO 11898 high-speed CAN physical-layer compatibility, and an 8-pin SOIC package. It is designed to connect a 3.3-V CAN controller to a physical CAN bus in industrial, automotive, and embedded systems. The device also provides ultra-low-power Shutdown and Standby modes for battery-powered equipment. A CAN transceiver is the physical-layer interface between a digital CAN controller and the differential CANH and CANL bus conductors. Unlike a general-purpose differential line driver, a CAN transceiver combines transmit, receive, bus-fault, and low-power functions in one device. The TCAN330 belongs to the TCAN33x family of 3.3-V CAN transceivers and is positioned for systems using ISO 11898 high-speed CAN. Verified device features include one-half CAN transceiver operation, data rates up to 1 Mbps, 3.3-V operation, an 8-SOIC package, and Shutdown and Standby operating states. The SOIC package supports conventional surface-mount assembly, while the low-power modes are useful when a portable or battery-operated controller must disconnect from the bus without losing its local supply. Texas Instruments states that this family is available in standard 8-pin SOIC packages for drop-in compatibility. The TCAN330D physically separates the controller-side TXD and RXD signals from the bus-side CANH and CANL interface. Designers must still provide correct controller logic levels, bus termination, decoupling, and protection appropriate to the vehicle or industrial environment. The provided data does not establish every absolute maximum rating, transceiver delay, output-level value, or bus-fault threshold, so those specifications should be confirmed in the manufacturer datasheet before release. Typical uses include industrial automation controllers, electric-vehicle subsystems, battery management gateways, motor-control equipment, diagnostic interfaces, and embedded CAN nodes. For a compact design, the logic interface is tied to a 3.3-V CAN controller, while the differential bus side connects to CANH and CANL through the application's termination and protection network. Layout and power integrity remain critical even in an eight-pin interface IC. Place required decoupling capacitors close to the supply pins, keep bus traces short and appropriately routed as a differential pair, and verify common-mode and fault-tolerance requirements against the complete system. Because no verified pricing, lifecycle, or complete pin-level table was supplied, those details remain marked for confirmation rather than inferred. This product page combines verified distributor and manufacturer information, CAN physical-layer context, practical design guidance, and explicit data gaps. The resulting TCAN330D reference is intended to accelerate component review while keeping engineering decisions traceable to the supplied sources.

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.

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.
